This combination is achieved through advances in device architecture and the use of 65nm technology making the devices suitable for high-volume, high-speed, low-cost applications. The LatticeECP3 device family expands look-up-table (LUT) capacity to 149K logic elements and supports up to 586 user I/Os. The LatticeECP3 device family also offers up to 320 18x18 multipliers and a wide range of parallel I/O standards. The LatticeECP3 FPGA fabric is optimized with high performance and low cost in mind. The LatticeECP3 devices utilize reconfigurable SRAM logic technology and provide popular building blocks such as LUT-based logic, distributed and embedded memory, Phase Locked Loops (PLLs), Delay Locked Loops (DLLs), pre-engineered source synchronous I/O support, enhanced sysDSP slices and advanced configuration support, including encryption and dual-boot capabilities. The pre-engineered source synchronous logic implemented in the LatticeECP3 device family supports a broad range of interface standards, including DDR3, XGMII and 7:1 LVDS. The LatticeECP3 device family also features high speed SERDES with dedicated PCS functions. High jitter tolerance and low transmit jitter allow the SERDES plus PCS blocks to be configured to support an array of popular data protocols including PCI Express, SMPTE, Ethernet (XAUI, GbE, and SGMII) and CPRI. Transmit Pre-emphasis and Receive Equalization settings make the SERDES suitable for transmission and reception over various forms of media. The LatticeECP3 devices also provide flexible, reliable and secure configuration options, such as dual-boot capability, bit-stream encryption, and TransFR field upgrade features. The Lattice DiamondTM and ispLEVER(R) design software allows large complex designs to be efficiently implemented using the LatticeECP3 FPGA family. Synthesis library support for LatticeECP3 is available for popular logic synthesis tools. Diamond and ispLEVER tools use the synthesis tool output along with the constraints from its floor planning tools to place and route the design in the LatticeECP3 device. The tools extract the timing from the routing and back-annotate it into the design for timing verification. Lattice provides many pre-engineered IP (Intellectual Property) modules for the LatticeECP3 family. By using these configurable soft core IPs as standardized blocks, designers are free to concentrate on the unique aspects of their design, increasing their productivity. 1-2 LatticeECP3 Family Data Sheet Architecture June 2013 Data Sheet DS1021 Architecture Overview Each LatticeECP3 device contains an array of logic blocks surrounded by Programmable I/O Cells (PIC). Interspersed between the rows of logic blocks are rows of sysMEMTM Embedded Block RAM (EBR) and rows of sysDSPTM Digital Signal Processing slices, as shown in Figure 2-1. The LatticeECP3-150 has four rows of DSP slices; all other LatticeECP3 devices have two rows of DSP slices. In addition, the LatticeECP3 family contains SERDES Quads on the bottom of the device. There are two kinds of logic blocks, the Programmable Functional Unit (PFU) and Programmable Functional Unit without RAM (PFF). The PFU contains the building blocks for logic, arithmetic, RAM and ROM functions. The PFF block contains building blocks for logic, arithmetic and ROM functions. Both PFU and PFF blocks are optimized for flexibility, allowing complex designs to be implemented quickly and efficiently. Logic Blocks are arranged in a twodimensional array. Only one type of block is used per row. The LatticeECP3 devices contain one or more rows of sysMEM EBR blocks. sysMEM EBRs are large, dedicated 18Kbit fast memory blocks. Each sysMEM block can be configured in a variety of depths and widths as RAM or ROM. In addition, LatticeECP3 devices contain up to two rows of DSP slices. Each DSP slice has multipliers and adder/accumulators, which are the building blocks for complex signal processing capabilities. The LatticeECP3 devices feature up to 16 embedded 3.2Gbps SERDES (Serializer / Deserializer) channels. Each SERDES channel contains independent 8b/10b encoding / decoding, polarity adjust and elastic buffer logic. Each group of four SERDES channels, along with its Physical Coding Sub-layer (PCS) block, creates a quad. The functionality of the SERDES/PCS quads can be controlled by memory cells set during device configuration or by registers that are addressable during device operation. The registers in every quad can be programmed via the SERDES Client Interface (SCI). These quads (up to four) are located at the bottom of the devices. Each PIC block encompasses two PIOs (PIO pairs) with their respective sysI/O buffers. The sysI/O buffers of the LatticeECP3 devices are arranged in seven banks, allowing the implementation of a wide variety of I/O standards. In addition, a separate I/O bank is provided for the programming interfaces. 50% of the PIO pairs on the left and right edges of the device can be configured as LVDS transmit/receive pairs. The PIC logic also includes pre-engineered support to aid in the implementation of high speed source synchronous standards such as XGMII, 7:1 LVDS, along with memory interfaces including DDR3. The LatticeECP3 registers in PFU and sysI/O can be configured to be SET or RESET. After power up and the device is configured, it enters into user mode with these registers SET/RESET according to the configuration setting, allowing the device entering to a known state for predictable system function. Other blocks provided include PLLs, DLLs and configuration functions. The LatticeECP3 architecture provides two Delay Locked Loops (DLLs) and up to ten Phase Locked Loops (PLLs). The PLL and DLL blocks are located at the end of the EBR/DSP rows. The configuration block that supports features such as configuration bit-stream decryption, transparent updates and dual-boot support is located toward the center of this EBR row. Every device in the LatticeECP3 family supports a sysCONFIGTM port located in the corner between banks one and two, which allows for serial or parallel device configuration. In addition, every device in the family has a JTAG port. This family also provides an on-chip oscillator and soft error detect capability. The LatticeECP3 devices use 1.2V as their core voltage.

PFU Blocks The core of the LatticeECP3 device consists of PFU blocks, which are provided in two forms, the PFU and PFF. The PFUs can be programmed to perform Logic, Arithmetic, Distributed RAM and Distributed ROM functions. PFF blocks can be programmed to perform Logic, Arithmetic and ROM functions. Except where necessary, the remainder of this data sheet will use the term PFU to refer to both PFU and PFF blocks. Each PFU block consists of four interconnected slices numbered 0-3 as shown in Figure 2-2. Each slice contains two LUTs. All the interconnections to and from PFU blocks are from routing. There are 50 inputs and 23 outputs associated with each PFU block. 2-2 Architecture LatticeECP3 Family Data Sheet Figure 2-2.

For PFUs, Slice 0 through Slice 2 can be configured as distributed memory, a capability not available in the PFF. Table 2-1 shows the capability of the slices in both PFF and PFU blocks along with the operation modes they enable. In addition, each PFU contains logic that allows the LUTs to be combined to perform functions such as LUT5, LUT6, LUT7 and LUT8. There is control logic to perform set/reset functions (programmable as synchronous/ asynchronous), clock select, chip-select and wider RAM/ROM functions. Table 2-1.

The registers in the slice can be configured for positive/negative and edge triggered or level sensitive clocks. Slices 0, 1 and 2 have 14 input signals: 13 signals from routing and one from the carry-chain (from the adjacent slice or PFU). There are seven outputs: six to routing and one to carry-chain (to the adjacent PFU). Slice 3 has 10 input signals from routing and four signals to routing.

See Figure 2-3 for connection details. 2. Requires two PFUs. 2-4 Architecture LatticeECP3 Family Data Sheet Modes of Operation Each slice has up to four potential modes of operation: Logic, Ripple, RAM and ROM. Logic Mode In this mode, the LUTs in each slice are configured as 4-input combinatorial lookup tables. A LUT4 can have 16 possible input combinations. Any four input logic functions can be generated by programming this lookup table. Since there are two LUT4s per slice, a LUT5 can be constructed within one slice. Larger look-up tables such as LUT6, LUT7 and LUT8 can be constructed by concatenating other slices. Note LUT8 requires more than four slices. Ripple Mode Ripple mode supports the efficient implementation of small arithmetic functions. In ripple mode, the following functions can be implemented by each slice: * Addition 2-bit * Subtraction 2-bit * Add/Subtract 2-bit using dynamic control * Up counter 2-bit * Down counter 2-bit * Up/Down counter with asynchronous clear * Up/Down counter with preload (sync) * Ripple mode multiplier building block * Multiplier support * Comparator functions of A and B inputs - A greater-than-or-equal-to B - A not-equal-to B - A less-than-or-equal-to B Ripple Mode includes an optional configuration that performs arithmetic using fast carry chain methods. In this configuration (also referred to as CCU2 mode) two additional signals, Carry Generate and Carry Propagate, are generated on a per slice basis to allow fast arithmetic functions to be constructed by concatenating Slices. RAM Mode In this mode, a 16x4-bit distributed single port RAM (SPR) can be constructed using each LUT block in Slice 0 and Slice 1 as a 16x1-bit memory. Slice 2 is used to provide memory address and control signals. A 16x2-bit pseudo dual port RAM (PDPR) memory is created by using one Slice as the read-write port and the other companion slice as the read-only port. LatticeECP3 devices support distributed memory initialization. The Lattice design tools support the creation of a variety of different size memories. Where appropriate, the software will construct these using distributed memory primitives that represent the capabilities of the PFU. Table 2-3 shows the number of slices required to implement different distributed RAM primitives. For more information about using RAM in LatticeECP3 devices, please see TN1179, LatticeECP3 Memory Usage Guide. Table 2-3. Number of Slices Required to Implement Distributed RAM Number of slices SPR 16X4 PDPR 16X4 3 3 Note: SPR = Single Port RAM, PDPR = Pseudo Dual Port RAM 2-5 Architecture LatticeECP3 Family Data Sheet ROM Mode ROM mode uses the LUT logic; hence, Slices 0 through 3 can be used in ROM mode. Preloading is accomplished through the programming interface during PFU configuration. For more information, please refer to TN1179, LatticeECP3 Memory Usage Guide. Routing There are many resources provided in the LatticeECP3 devices to route signals individually or as busses with related control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing) segments. The LatticeECP3 family has an enhanced routing architecture that produces a compact design. The Diamond and ispLEVER design software tool suites take the output of the synthesis tool and places and routes the design. sysCLOCK PLLs and DLLs The sysCLOCK PLLs provide the ability to synthesize clock frequencies. The devices in the LatticeECP3 family support two to ten full-featured General Purpose PLLs. General Purpose PLL The architecture of the PLL is shown in Figure 2-4. A description of the PLL functionality follows. CLKI is the reference frequency (generated either from the pin or from routing) for the PLL. CLKI feeds into the Input Clock Divider block. The CLKFB is the feedback signal (generated from CLKOP, CLKOS or from a user clock pin/logic). This signal feeds into the Feedback Divider. The Feedback Divider is used to multiply the reference frequency. Both the input path and feedback signals enter the Phase Frequency Detect Block (PFD) which detects first for the frequency, and then the phase, of the CLKI and CLKFB are the same which then drives the Voltage Controlled Oscillator (VCO) block. In this block the difference between the input path and feedback signals is used to control the frequency and phase of the oscillator. A LOCK signal is generated by the VCO to indicate that the VCO has locked onto the input clock signal. In dynamic mode, the PLL may lose lock after a dynamic delay adjustment and not relock until the tLOCK parameter has been satisfied. The output of the VCO then enters the CLKOP divider. The CLKOP divider allows the VCO to operate at higher frequencies than the clock output (CLKOP), thereby increasing the frequency range. The Phase/Duty Cycle/Duty Trim block adjusts the phase and duty cycle of the CLKOS signal. The phase/duty cycle setting can be pre-programmed or dynamically adjusted. A secondary divider takes the CLKOP or CLKOS signal and uses it to derive lower frequency outputs (CLKOK). The primary output from the CLKOP divider (CLKOP) along with the outputs from the secondary dividers (CLKOK and CLKOK2) and Phase/Duty select (CLKOS) are fed to the clock distribution network. The PLL allows two methods for adjusting the phase of signal. The first is referred to as Fine Delay Adjustment. This inserts up to 16 nominal 125ps delays to be applied to the secondary PLL output. The number of steps may be set statically or from the FPGA logic. The second method is referred to as Coarse Phase Adjustment. This allows the phase of the rising and falling edge of the secondary PLL output to be adjusted in 22.5 degree steps. The number of steps may be set statically or from the FPGA logic. 2-6 Architecture LatticeECP3 Family Data Sheet Figure 2-4.

CLKI is the input frequency (generated either from the pin or routing) for the DLL. CLKI feeds into the output muxes block to bypass the DLL, directly to the DELAY CHAIN block and (directly or through divider circuit) to the reference input of the Phase Detector (PD) input mux. The reference signal for the PD can also be generated from the Delay Chain signals. The feedback input to the PD is generated from the CLKFB pin or from a tapped signal from the Delay chain. The PD produces a binary number proportional to the phase and frequency difference between the reference and feedback signals. Based on these inputs, the ALU determines the correct digital control codes to send to the delay 2-7 Architecture LatticeECP3 Family Data Sheet chain in order to better match the reference and feedback signals. This digital code from the ALU is also transmitted via the Digital Control bus (DCNTL) bus to its associated Slave Delay lines (two per DLL). The ALUHOLD input allows the user to suspend the ALU output at its current value. The UDDCNTL signal allows the user to latch the current value on the DCNTL bus. The DLL has two clock outputs, CLKOP and CLKOS. These outputs can individually select one of the outputs from the tapped delay line. The CLKOS has optional fine delay shift and divider blocks to allow this output to be further modified, if required. The fine delay shift block allows the CLKOS output to phase shifted a further 45, 22.5 or 11.25 degrees relative to its normal position. Both the CLKOS and CLKOP outputs are available with optional duty cycle correction. Divide by two and divide by four frequencies are available at CLKOS. The LOCK output signal is asserted when the DLL is locked. Figure 2-5 shows the DLL block diagram and Table 2-5 provides a description of the DLL inputs and outputs. The user can configure the DLL for many common functions such as time reference delay mode and clock injection removal mode. Lattice provides primitives in its design tools for these functions.

The DLLs are in the lowest EBR row and located adjacent to the EBR. Each DLL replaces one EBR block. One Slave Delay line is placed adjacent to the DLL and the duplicate Slave Delay line (in Figure 2-6) for the DLL is placed in the I/O ring between Banks 6 and 7 and Banks 2 and 3. The outputs from the DLL and Slave Delay lines are fed to the clock distribution network. For more information, please see TN1178, LatticeECP3 sysCLOCK PLL/DLL Design and Usage Guide. Figure 2-6.

The allowable combinations are: * PLL to PLL supported * PLL to DLL supported The DLLs in the LatticeECP3 are used to shift the clock in relation to the data for source synchronous inputs. PLLs are used for frequency synthesis and clock generation for source synchronous interfaces. Cascading PLL and DLL blocks allows applications to utilize the unique benefits of both DLLs and PLLs. For further information about the DLL, please see the list of technical documentation at the end of this data sheet. PLL/DLL PIO Input Pin Connections All LatticeECP3 devices contains two DLLs and up to ten PLLs, arranged in quadrants. If a PLL and a DLL are next to each other, they share input pins as shown in the Figure 2-7. Figure 2-7. Sharing of PIO Pins by PLLs and DLLs in LatticeECP3 Devices PLL_PIO PLL DLL DLL_PIO Note: Not every PLL has an associated DLL. Clock Dividers LatticeECP3 devices have two clock dividers, one on the left side and one on the right side of the device. These are intended to generate a slower-speed system clock from a high-speed edge clock. The block operates in a /2, /4 or /8 mode and maintains a known phase relationship between the divided down clock and the high-speed clock based on the release of its reset signal. The clock dividers can be fed from selected PLL/DLL outputs, the Slave Delay lines, routing or from an external clock input. The clock divider outputs serve as primary clock sources and feed into the clock distribution network. The Reset (RST) control signal resets input and asynchronously forces all outputs to low. The RELEASE signal releases outputs synchronously to the input clock. For further information on clock dividers, please see TN1178, LatticeECP3 sysCLOCK PLL/DLL Design and Usage Guide. Figure 2-8 shows the clock divider connections. 2-10 Architecture LatticeECP3 Family Data Sheet Figure 2-8. Clock Divider Connections ECLK1 ECLK2 /1 CLKOP (PLL) CLKOP (DLL) /2 CLKDIV /4 RST /8 RELEASE Clock Distribution Network LatticeECP3 devices have eight quadrant-based primary clocks and eight secondary clock/control sources. Two high performance edge clocks are available on the top, left, and right edges of the device to support high speed interfaces. These clock sources are selected from external I/Os, the sysCLOCK PLLs, DLLs or routing. These clock sources are fed throughout the chip via a clock distribution system. Primary Clock Sources LatticeECP3 devices derive clocks from six primary source types: PLL outputs, DLL outputs, CLKDIV outputs, dedicated clock inputs, routing and SERDES Quads. LatticeECP3 devices have two to ten sysCLOCK PLLs and two DLLs, located on the left and right sides of the device. There are six dedicated clock inputs: two on the top side, two on the left side and two on the right side of the device. Figures 2-9, 2-10 and 2-11 show the primary clock sources for LatticeECP3 devices. Figure 2-9.

A global primary clock is a primary clock that is distributed to all quadrants. The clock routing structure in LatticeECP3 devices consists of a network of eight primary clock lines (CLK0 through CLK7) per quadrant. The primary clocks of each quadrant are generated from muxes located in the center of the device. All the clock sources are connected to these muxes. Figure 2-12 shows the clock routing for one quadrant. Each quadrant mux is identical. If desired, any clock can be routed globally. Figure 2-12.

When a clock network is disabled, all the logic fed by that clock does not toggle, reducing the overall power consumption of the device. Dynamic Clock Select (DCS) The DCS is a smart multiplexer function available in the primary clock routing. It switches between two independent input clock sources without any glitches or runt pulses. This is achieved regardless of when the select signal is toggled. There are two DCS blocks per quadrant; in total, there are eight DCS blocks per device. The inputs to the DCS block come from the center muxes. The output of the DCS is connected to primary clocks CLK6 and CLK7 (see Figure 2-12). Figure 2-13 shows the timing waveforms of the default DCS operating mode. The DCS block can be programmed to other modes. For more information about the DCS, please see the list of technical documentation at the end of this data sheet. Figure 2-13. DCS Waveforms CLK0 CLK1 SEL DCSOUT 2-13 Architecture LatticeECP3 Family Data Sheet Secondary Clock/Control Sources LatticeECP3 devices derive eight secondary clock sources (SC0 through SC7) from six dedicated clock input pads and the rest from routing. Figure 2-14 shows the secondary clock sources. All eight secondary clock sources are defined as inputs to a per-region mux SC0-SC7. SC0-SC3 are primary for control signals (CE and/or LSR), and SC4-SC7 are for the clock. In an actual implementation, there is some overlap to maximize routability. In addition to SC0-SC3, SC7 is also an input to the control signals (LSR or CE). SC0-SC2 are also inputs to clocks along with SC4-SC7. Figure 2-14.

Secondary Clock/Control Routing Global secondary clock is a secondary clock that is distributed to all regions. The purpose of the secondary clock routing is to distribute the secondary clock sources to the secondary clock regions. Secondary clocks in the LatticeECP3 devices are region-based resources. Certain EBR rows and special vertical routing channels bind the secondary clock regions. This special vertical routing channel aligns with either the left edge of the center DSP slice in the DSP row or the center of the DSP row. Figure 2-15 shows this special vertical routing channel and the 20 secondary clock regions for the LatticeECP3 family of devices. All devices in the LatticeECP3 family have eight secondary clock resources per region (SC0 to SC7). The same secondary clock routing can be used for control signals. 2-14 Architecture LatticeECP3 Family Data Sheet Table 2-6.

All the primary clocks and seven secondary clocks are routed to this clock selection mux. Other signals can be used as a clock input to the slices via routing. Slice controls are generated from the secondary clocks/controls or other signals connected via routing. If none of the signals are selected for both clock and control then the default value of the mux output is 1. Slice 3 does not have any registers; therefore it does not have the clock or control muxes. Figure 2-17.

Edge clock resources can be driven from adjacent edge clock PIOs, primary clock PIOs, PLLs, DLLs, Slave Delay and clock dividers as shown in Figure 2-19. Figure 2-19.

Clock inputs can be configured in differential or single ended mode. 2. The two DLLs can also drive the two top edge clocks. 3. The top left and top right PLL can also drive the two top edge clocks. Edge Clock Routing LatticeECP3 devices have a number of high-speed edge clocks that are intended for use with the PIOs in the implementation of high-speed interfaces. There are six edge clocks per device: two edge clocks on each of the top, left, and right edges. Different PLL and DLL outputs are routed to the two muxes on the left and right sides of the device. In addition, the CLKINDEL signal (generated from the DLL Slave Delay Line block) is routed to all the edge clock muxes on the left and right sides of the device. Figure 2-20 shows the selection muxes for these clocks. 2-17 Architecture LatticeECP3 Family Data Sheet Figure 2-20.

They are used to clock the I/O registers and thus are ideal for creating I/O interfaces with a single clock signal and a wide data bus. They are also used for DDR Memory or Generic DDR interfaces. 2-18 Architecture LatticeECP3 Family Data Sheet The edge clocks on the top, left, and right sides of the device can drive the secondary clocks or general routing resources of the device. The left and right side edge clocks also can drive the primary clock network through the clock dividers (CLKDIV). sysMEM Memory LatticeECP3 devices contain a number of sysMEM Embedded Block RAM (EBR). The EBR consists of an 18-Kbit RAM with memory core, dedicated input registers and output registers with separate clock and clock enable. Each EBR includes functionality to support true dual-port, pseudo dual-port, single-port RAM, ROM and FIFO buffers (via external PFUs). sysMEM Memory Block The sysMEM block can implement single port, dual port or pseudo dual port memories. Each block can be used in a variety of depths and widths as shown in Table 2-7. FIFOs can be implemented in sysMEM EBR blocks by implementing support logic with PFUs. The EBR block facilitates parity checking by supporting an optional parity bit for each data byte. EBR blocks provide byte-enable support for configurations with18-bit and 36-bit data widths. For more information, please see TN1179, LatticeECP3 Memory Usage Guide. Table 2-7. sysMEM Block Configurations Memory Mode Configurations Single Port 16,384 x 1 8,192 x 2 4,096 x 4 2,048 x 9 1,024 x 18 512 x 36 True Dual Port 16,384 x 1 8,192 x 2 4,096 x 4 2,048 x 9 1,024 x 18 Pseudo Dual Port 16,384 x 1 8,192 x 2 4,096 x 4 2,048 x 9 1,024 x 18 512 x 36 Bus Size Matching All of the multi-port memory modes support different widths on each of the ports. The RAM bits are mapped LSB word 0 to MSB word 0, LSB word 1 to MSB word 1, and so on. Although the word size and number of words for each port varies, this mapping scheme applies to each port. RAM Initialization and ROM Operation If desired, the contents of the RAM can be pre-loaded during device configuration. By preloading the RAM block during the chip configuration cycle and disabling the write controls, the sysMEM block can also be utilized as a ROM. Memory Cascading Larger and deeper blocks of RAM can be created using EBR sysMEM Blocks. Typically, the Lattice design tools cascade memory transparently, based on specific design inputs. 2-19 Architecture LatticeECP3 Family Data Sheet Single, Dual and Pseudo-Dual Port Modes In all the sysMEM RAM modes the input data and address for the ports are registered at the input of the memory array. The output data of the memory is optionally registered at the output. EBR memory supports the following forms of write behavior for single port or dual port operation: 1. Normal - Data on the output appears only during a read cycle. During a write cycle, the data (at the current address) does not appear on the output. This mode is supported for all data widths. 2. Write Through - A copy of the input data appears at the output of the same port during a write cycle. This mode is supported for all data widths. 3. Read-Before-Write (EA devices only) - When new data is written, the old content of the address appears at the output. This mode is supported for x9, x18, and x36 data widths. Memory Core Reset The memory array in the EBR utilizes latches at the A and B output ports. These latches can be reset asynchronously or synchronously. RSTA and RSTB are local signals, which reset the output latches associated with Port A and Port B, respectively. The Global Reset (GSRN) signal can reset both ports. The output data latches and associated resets for both ports are as shown in Figure 2-22. Figure 2-22. Memory Core Reset Memory Core D SET Q Port A[17:0] LCLR Output Data Latches D SET Q Port B[17:0] LCLR RSTA RSTB GSRN Programmable Disable For further information on the sysMEM EBR block, please see the list of technical documentation at the end of this data sheet. sysDSPTM Slice The LatticeECP3 family provides an enhanced sysDSP architecture, making it ideally suited for low-cost, high-performance Digital Signal Processing (DSP) applications. Typical functions used in these applications are Finite Impulse Response (FIR) filters, Fast Fourier Transforms (FFT) functions, Correlators, Reed-Solomon/Turbo/Convolution encoders and decoders. These complex signal processing functions use similar building blocks such as multiply-adders and multiply-accumulators. sysDSP Slice Approach Compared to General DSP Conventional general-purpose DSP chips typically contain one to four (Multiply and Accumulate) MAC units with fixed data-width multipliers; this leads to limited parallelism and limited throughput. Their throughput is increased by higher clock speeds. The LatticeECP3, on the other hand, has many DSP slices that support different data widths. 2-20 Architecture LatticeECP3 Family Data Sheet This allows designers to use highly parallel implementations of DSP functions. Designers can optimize DSP performance vs. area by choosing appropriate levels of parallelism. Figure 2-23 compares the fully serial implementation to the mixed parallel and serial implementation.

These enhancements provide improved flexibility and resource utilization. The LatticeECP3 sysDSP Slice supports many functions that include the following: * Multiply (one 18x36, two 18x18 or four 9x9 Multiplies per Slice) * Multiply (36x36 by cascading across two sysDSP slices) * Multiply Accumulate (up to 18x36 Multipliers feeding an Accumulator that can have up to 54-bit resolution) * Two Multiplies feeding one Accumulate per cycle for increased processing with lower latency (two 18x18 Multiplies feed into an accumulator that can accumulate up to 52 bits) * Flexible saturation and rounding options to satisfy a diverse set of applications situations * Flexible cascading across DSP slices - Minimizes fabric use for common DSP and ALU functions - Enables implementation of FIR Filter or similar structures using dedicated sysDSP slice resources only - Provides matching pipeline registers - Can be configured to continue cascading from one row of sysDSP slices to another for longer cascade chains * Flexible and Powerful Arithmetic Logic Unit (ALU) Supports: - Dynamically selectable ALU OPCODE - Ternary arithmetic (addition/subtraction of three inputs) - Bit-wise two-input logic operations (AND, OR, NAND, NOR, XOR and XNOR) - Eight flexible and programmable ALU flags that can be used for multiple pattern detection scenarios, such 2-21 Architecture LatticeECP3 Family Data Sheet as, overflow, underflow and convergent rounding, etc. - Flexible cascading across slices to get larger functions * RTL Synthesis friendly synchronous reset on all registers, while still supporting asynchronous reset for legacy users * Dynamic MUX selection to allow Time Division Multiplexing (TDM) of resources for applications that require processor-like flexibility that enables different functions for each clock cycle For most cases, as shown in Figure 2-24, the LatticeECP3 DSP slice is backwards-compatible with the LatticeECP2TM sysDSP block, such that, legacy applications can be targeted to the LatticeECP3 sysDSP slice. The functionality of one LatticeECP2 sysDSP Block can be mapped into two adjacent LatticeECP3 sysDSP slices, as shown in Figure 2-25. Figure 2-24.

The input register in all the elements can be directly loaded or can be loaded as a shift register from previous operand registers. By selecting "dynamic operation" the following operations are possible: * In the Add/Sub option the Accumulator can be switched between addition and subtraction on every cycle. * The loading of operands can switch between parallel and serial operations. 2-23 Architecture LatticeECP3 Family Data Sheet For further information, please refer to TN1182, LatticeECP3 sysDSP Usage Guide.

Adder trees are implemented fully in sysDSP slices, improving the performance. Cascading of slices uses the signals CIN, COUT and C Mux of the slice. Addition The LatticeECP3 sysDSP slice allows for the bypassing of multipliers and cascading of adder logic. High performance adder functions are implemented without the use of LUTs. The maximum width adders that can be implemented are 54-bit. Rounding The rounding operation is implemented in the ALU and is done by adding a constant followed by a truncation operation. The rounding methods supported are: * Rounding to zero (RTZ) * Rounding to infinity (RTI) * Dynamic rounding * Random rounding * Convergent rounding 2-29 Architecture LatticeECP3 Family Data Sheet ALU Flags The sysDSP slice provides a number of flags from the ALU including: * Equal to zero (EQZ) * Equal to zero with mask (EQZM) * Equal to one with mask (EQOM) * Equal to pattern with mask (EQPAT) * Equal to bit inverted pattern with mask (EQPATB) * Accumulator Overflow (OVER) * Accumulator Underflow (UNDER) * Either over or under flow supporting LatticeECP2 legacy designs (OVERUNDER) Clock, Clock Enable and Reset Resources Global Clock, Clock Enable and Reset signals from routing are available to every sysDSP slice.

GSRN Control from routing Global Set/Reset 1. Signals available on left/right/top edges only. 2. Selected PIO. PIO The PIO contains four blocks: an input register block, output register block, tristate register block and a control logic block. These blocks contain registers for operating in a variety of modes along with the necessary clock and selection logic. Input Register Block The input register blocks for the PIOs, in the left, right and top edges, contain delay elements and registers that can be used to condition high-speed interface signals, such as DDR memory interfaces and source synchronous interfaces, before they are passed to the device core. Figure 2-33 shows the input register block for the left, right and top edges. The input register block for the bottom edge contains one element to register the input signal and no DDR registers. The following description applies to the input register block for PIOs in the left, right and top edges only. 2-32 Architecture LatticeECP3 Family Data Sheet Input signals are fed from the sysI/O buffer to the input register block (as signal DI). If desired, the input signal can bypass the register and delay elements and be used directly as a combinatorial signal (INDD), a clock (INCK) and, in selected blocks, the input to the DQS delay block. If an input delay is desired, designers can select either a fixed delay or a dynamic delay DEL[3:0]. The delay, if selected, reduces input register hold time requirements when using a global clock. The input block allows three modes of operation. In single data rate (SDR) the data is registered with the system clock by one of the registers in the single data rate sync register block. In DDR mode, two registers are used to sample the data on the positive and negative edges of the modified DQS (ECLKDQSR) in the DDR Memory mode or ECLK signal when using DDR Generic mode, creating two data streams. Before entering the core, these two data streams are synchronized to the system clock to generate two data streams. A gearbox function can be implemented in each of the input registers on the left and right sides. The gearbox function takes a double data rate signal applied to PIOA and converts it as four data streams, INA, IPA, INB and IPB. The two data streams from the first set of DDR registers are synchronized to the edge clock and then to the system clock before entering the core. Figure 2-30 provides further information on the use of the gearbox function. The signal DDRCLKPOL controls the polarity of the clock used in the synchronization registers. It ensures adequate timing when data is transferred to the system clock domain from the ECLKDQSR (DDR Memory Interface mode) or ECLK (DDR Generic mode). The DDRLAT signal is used to ensure the data transfer from the synchronization registers to the clock transfer and gearbox registers. The ECLKDQSR, DDRCLKPOL and DDRLAT signals are generated in the DQS Read Control Logic Block. See Figure 2-37 for an overview of the DQS read control logic. Further discussion about using the DQS strobe in this module is discussed in the DDR Memory section of this data sheet. Please see TN1180, LatticeECP3 High-Speed I/O Interface for more information on this topic. 2-33 Architecture LatticeECP3 Family Data Sheet Figure 2-33.

Note: Simplified diagram does not show CE/SET/REST details. Output Register Block The output register block registers signals from the core of the device before they are passed to the sysI/O buffers. The blocks on the left and right PIOs contain registers for SDR and full DDR operation. The topside PIO block is the same as the left and right sides except it does not support ODDRX2 gearing of output logic. ODDRX2 gearing is used in DDR3 memory interfaces.The PIO blocks on the bottom contain the SDR registers but do not support generic DDR. Figure 2-34 shows the Output Register Block for PIOs on the left and right edges. In SDR mode, OPOSA feeds one of the flip-flops that then feeds the output. The flip-flop can be configured as a Dtype or latch. In DDR mode, two of the inputs are fed into registers on the positive edge of the clock. At the next clock cycle, one of the registered outputs is also latched. A multiplexer running off the same clock is used to switch the mux between the 11 and 01 inputs that will then feed the output. A gearbox function can be implemented in the output register block that takes four data streams: OPOSA, ONEGA, OPOSB and ONEGB. All four data inputs are registered on the positive edge of the system clock and two of them are also latched. The data is then output at a high rate using a multiplexer that runs off the DQCLK0 and DQCLK1 clocks. DQCLK0 and DQCLK1 are used in this case to transfer data from the system clock to the edge clock domain. These signals are generated in the DQS Write Control Logic block. See Figure 2-37 for an overview of the DQS write control logic. Please see TN1180, LatticeECP3 High-Speed I/O Interface for more information on this topic. Further discussion on using the DQS strobe in this module is discussed in the DDR Memory section of this data sheet. 2-34 Architecture LatticeECP3 Family Data Sheet Figure 2-34.

The block contains a register for SDR operation and an additional register for DDR operation. In SDR and non-gearing DDR modes, TS input feeds one of the flip-flops that then feeds the output. In DDRX2 mode, the register TS input is fed into another register that is clocked using the DQCLK0 and DQCLK1 signals. The output of this register is used as a tristate control. ISI Calibration The setting for Inter-Symbol Interference (ISI) cancellation occurs in the output register block. ISI correction is only available in the DDRX2 modes. ISI calibration settings exist once per output register block, so each I/O in a DQS12 group may have a different ISI calibration setting. The ISI block extends output signals at certain times, as a function of recent signal history. So, if the output pattern consists of a long strings of 0's to long strings of 1's, there are no delays on output signals. However, if there are quick, successive transitions from 010, the block will stretch out the binary 1. This is because the long trail of 0's will cause these symbols to interfere with the logic 1. Likewise, if there are quick, successive transitions from 101, the block will stretch out the binary 0. This block is controlled by a 3-bit delay control that can be set in the DQS control logic block. For more information about this topic, please see the list of technical documentation at the end of this data sheet. 2-35 Architecture LatticeECP3 Family Data Sheet Control Logic Block The control logic block allows the selection and modification of control signals for use in the PIO block. DDR Memory Support Certain PICs have additional circuitry to allow the implementation of high-speed source synchronous and DDR, DDR2 and DDR3 memory interfaces. The support varies by the edge of the device as detailed below. Left and Right Edges The left and right sides of the PIC have fully functional elements supporting DDR, DDR2, and DDR3 memory interfaces. One of every 12 PIOs supports the dedicated DQS pins with the DQS control logic block. Figure 2-35 shows the DQS bus spanning 11 I/O pins. Two of every 12 PIOs support the dedicated DQS and DQS# pins with the DQS control logic block. Bottom Edge PICs on the bottom edge of the device do not support DDR memory and Generic DDR interfaces. Top Edge PICs on the top side are similar to the PIO elements on the left and right sides but do not support gearing on the output registers. Hence, the modes to support output/tristate DDR3 memory are removed on the top side. The exact DQS pins are shown in a dual function in the Logic Signal Connections table in this data sheet. Additional detail is provided in the Signal Descriptions table. The DQS signal from the bus is used to strobe the DDR data from the memory into input register blocks. Interfaces on the left, right and top edges are designed for DDR memories that support 10 bits of data. Figure 2-35. DQS Grouping on the Left, Right and Top Edges PIO A PADA "T" PIO B PADB "C" LVDS Pair PIO A PADA "T" PIO B PADB "C" PIO A PADA "T" PIO B PADB "C" LVDS Pair LVDS Pair PIO A DQS sysIO Buffer Delay PIO B Assigned DQS Pin PADA "T" LVDS Pair PADB "C" PIO A PADA "T" PIO B PADB "C" PIO A PADA "T" PIO B PADB "C" LVDS Pair LVDS Pair DLL Calibrated DQS Delay Block Source synchronous interfaces generally require the input clock to be adjusted in order to correctly capture data at the input register. For most interfaces, a PLL is used for this adjustment. However, in DDR memories the clock 2-36 Architecture LatticeECP3 Family Data Sheet (referred to as DQS) is not free-running so this approach cannot be used. The DQS Delay block provides the required clock alignment for DDR memory interfaces. The delay required for the DQS signal is generated by two dedicated DLLs (DDR DLL) on opposite side of the device. Each DLL creates DQS delays in its half of the device as shown in Figure 2-36. The DDR DLL on the left side will generate delays for all the DQS Strobe pins on Banks 0, 7 and 6 and DDR DLL on the right will generate delays for all the DQS pins on Banks 1, 2 and 3. The DDR DLL loop compensates for temperature, voltage and process variations by using the system clock and DLL feedback loop. DDR DLL communicates the required delay to the DQS delay block using a 7-bit calibration bus (DCNTL[6:0]) The DQS signal (selected PIOs only, as shown in Figure 2-35) feeds from the PAD through a DQS control logic block to a dedicated DQS routing resource. The DQS control logic block consists of DQS Read Control logic block that generates control signals for the read side and DQS Write Control logic that generates the control signals required for the write side. A more detailed DQS control diagram is shown in Figure 2-37, which shows how the DQS control blocks interact with the data paths. The DQS Read control logic receives the delay generated by the DDR DLL on its side and delays the incoming DQS signal by 90 degrees. This delayed ECLKDQSR is routed to 10 or 11 DQ pads covered by that DQS signal. This block also contains a polarity control logic that generates a DDRCLKPOL signal, which controls the polarity of the clock to the sync registers in the input register blocks. The DQS Read control logic also generates a DDRLAT signal that is in the input register block to transfer data from the first set of DDR register to the second set of DDR registers when using the DDRX2 gearbox mode for DDR3 memory interface. The DQS Write control logic block generates the DQCLK0 and DQCLK1 clocks used to control the output gearing in the Output register block which generates the DDR data output and the DQS output. They are also used to control the generation of the DQS output through the DQS output register block. In addition to the DCNTL [6:0] input from the DDR DLL, the DQS Write control block also uses a Dynamic Delay DYN DEL [7:0] attribute which is used to further delay the DQS to accomplish the write leveling found in DDR3 memory. Write leveling is controlled by the DDR memory controller implementation. The DYN DELAY can set 128 possible delay step settings. In addition, the most significant bit will invert the clock for a 180-degree shift of the incoming clock. This will generate the DQSW signal used to generate the DQS output in the DQS output register block. Figure 2-36 and Figure 2-37 show how the DQS transition signals that are routed to the PIOs. Please see TN1180, LatticeECP3 High-Speed I/O Interface for more information on this topic. 2-37 Architecture LatticeECP3 Family Data Sheet Figure 2-36.

DQS Local Bus DDR Data Pad Data Output Register Block Data Input Register Block DQS Output Register Block DQS Write Control Logic DQS Pad DQS Read Control Logic DQS Delay Block DDR DLL Polarity Control Logic In a typical DDR Memory interface design, the phase relationship between the incoming delayed DQS strobe and the internal system clock (during the READ cycle) is unknown. The LatticeECP3 family contains dedicated circuits to transfer data between these domains. A clock polarity selector is used to prevent set-up and hold violations at the domain transfer between DQS (delayed) and the system clock. This changes the edge on which the data is registered in the synchronizing registers in the input register block. This requires evaluation at the start of each READ cycle for the correct clock polarity. Prior to the READ operation in DDR memories, DQS is in tristate (pulled by termination). The DDR memory device drives DQS low at the start of the preamble state. A dedicated circuit detects the first DQS rising edge after the preamble state. This signal is used to control the polarity of the clock to the synchronizing registers. DDR3 Memory Support LatticeECP3 supports the read and write leveling required for DDR3 memory interfaces. Read leveling is supported by the use of the DDRCLKPOL and the DDRLAT signals generated in the DQS Read Control logic block. These signals dynamically control the capture of the data with respect to the DQS at the input register block. 2-39 Architecture LatticeECP3 Family Data Sheet To accomplish write leveling in DDR3, each DQS group has a slightly different delay that is set by DYN DELAY[7:0] in the DQS Write Control logic block. The DYN DELAY can set 128 possible delay step settings. In addition, the most significant bit will invert the clock for a 180-degree shift of the incoming clock. LatticeECP3 input and output registers can also support DDR gearing that is used to receive and transmit the high speed DDR data from and to the DDR3 Memory. LatticeECP3 supports the 1.5V SSTL I/O standard required for the DDR3 memory interface. For more information, refer to the sysIO section of this data sheet. Please see TN1180, LatticeECP3 High-Speed I/O Interface for more information on DDR Memory interface implementation in LatticeECP3. sysI/O Buffer Each I/O is associated with a flexible buffer referred to as a sysI/O buffer. These buffers are arranged around the periphery of the device in groups referred to as banks. The sysI/O buffers allow users to implement the wide variety of standards that are found in today's systems including LVDS, BLVDS, HSTL, SSTL Class I & II, LVCMOS, LVTTL, LVPECL, PCI. sysI/O Buffer Banks LatticeECP3 devices have six sysI/O buffer banks: six banks for user I/Os arranged two per side. The banks on the bottom side are wraparounds of the banks on the lower right and left sides. The seventh sysI/O buffer bank (Configuration Bank) is located adjacent to Bank 2 and has dedicated/shared I/Os for configuration. When a shared pin is not used for configuration it is available as a user I/O. Each bank is capable of supporting multiple I/O standards. Each sysI/O bank has its own I/O supply voltage (VCCIO). In addition, each bank, except the Configuration Bank, has voltage references, VREF1 and VREF2, which allow it to be completely independent from the others. Figure 2-38 shows the seven banks and their associated supplies. In LatticeECP3 devices, single-ended output buffers and ratioed input buffers (LVTTL, LVCMOS and PCI) are powered using VCCIO. LVTTL, LVCMOS33, LVCMOS25 and LVCMOS12 can also be set as fixed threshold inputs independent of VCCIO. Each bank can support up to two separate VREF voltages, VREF1 and VREF2, that set the threshold for the referenced input buffers. Some dedicated I/O pins in a bank can be configured to be a reference voltage supply pin. Each I/O is individually configurable based on the bank's supply and reference voltages. 2-40 Architecture LatticeECP3 Family Data Sheet Figure 2-38.

Top (Bank 0 and Bank 1) and Bottom sysIO Buffer Pairs (Single-Ended Outputs Only) The sysI/O buffer pairs in the top banks of the device consist of two single-ended output drivers and two sets of single-ended input buffers (both ratioed and referenced). One of the referenced input buffers can also be configured as a differential input. Only the top edge buffers have a programmable PCI clamp. The two pads in the pair are described as "true" and "comp", where the true pad is associated with the positive side of the differential input buffer and the comp (complementary) pad is associated with the negative side of the differential input buffer. The top and bottom sides are ideal for general purpose I/O, PCI, and inputs for LVDS (LVDS outputs are only allowed on the left and right sides). The top side can be used for the DDR3 ADDR/CMD signals. The I/O pins located on the top and bottom sides of the device (labeled PTxxA/B or PBxxA/B) are fully hot socketable. Note that the pads in Banks 3, 6 and 8 are wrapped around the corner of the device. In these banks, only the pads located on the top or bottom of the device are hot socketable. The top and bottom side pads can be identified by the Lattice Diamond tool. 2-41 Architecture LatticeECP3 Family Data Sheet 2. Left and Right (Banks 2, 3, 6 and 7) sysI/O Buffer Pairs (50% Differential and 100% Single-Ended Outputs) The sysI/O buffer pairs in the left and right banks of the device consist of two single-ended output drivers, two sets of single-ended input buffers (both ratioed and referenced) and one differential output driver. One of the referenced input buffers can also be configured as a differential input. In these banks the two pads in the pair are described as "true" and "comp", where the true pad is associated with the positive side of the differential I/O, and the comp (complementary) pad is associated with the negative side of the differential I/O. In addition, programmable on-chip input termination (parallel or differential, static or dynamic) is supported on these sides, which is required for DDR3 interface. However, there is no support for hot-socketing for the I/O pins located on the left and right side of the device as the PCI clamp is always enabled on these pins. LVDS, RSDS, PPLVDS and Mini-LVDS differential output drivers are available on 50% of the buffer pairs on the left and right banks. 3. Configuration Bank sysI/O Buffer Pairs (Single-Ended Outputs, Only on Shared Pins When Not Used by Configuration) The sysI/O buffers in the Configuration Bank consist of ratioed single-ended output drivers and single-ended input buffers. This bank does not support PCI clamp like the other banks on the top, left, and right sides. The two pads in the pair are described as "true" and "comp", where the true pad is associated with the positive side of the differential input buffer and the comp (complementary) pad is associated with the negative side of the differential input buffer. Programmable PCI clamps are only available on the top banks. PCI clamps are used primarily on inputs and bidirectional pads to reduce ringing on the receiving end. Typical sysI/O I/O Behavior During Power-up The internal power-on-reset (POR) signal is deactivated when VCC, VCCIO8 and VCCAUX have reached satisfactory levels. After the POR signal is deactivated, the FPGA core logic becomes active. It is the user's responsibility to ensure that all other VCCIO banks are active with valid input logic levels to properly control the output logic states of all the I/O banks that are critical to the application. For more information about controlling the output logic state with valid input logic levels during power-up in LatticeECP3 devices, see the list of technical documentation at the end of this data sheet. The VCC and VCCAUX supply the power to the FPGA core fabric, whereas the VCCIO supplies power to the I/O buffers. In order to simplify system design while providing consistent and predictable I/O behavior, it is recommended that the I/O buffers be powered-up prior to the FPGA core fabric. VCCIO supplies should be powered-up before or together with the VCC and VCCAUX supplies. Supported sysI/O Standards The LatticeECP3 sysI/O buffer supports both single-ended and differential standards. Single-ended standards can be further subdivided into LVCMOS, LVTTL and other standards. The buffers support the LVTTL, LVCMOS 1.2V, 1.5V, 1.8V, 2.5V and 3.3V standards. In the LVCMOS and LVTTL modes, the buffer has individual configuration options for drive strength, slew rates, bus maintenance (weak pull-up, weak pull-down, or a bus-keeper latch) and open drain. Other single-ended standards supported include SSTL and HSTL. Differential standards supported include LVDS, BLVDS, LVPECL, MLVDS, RSDS, Mini-LVDS, PPLVDS (point-to-point LVDS), TRLVDS (Transition Reduced LVDS), differential SSTL and differential HSTL. For further information on utilizing the sysI/O buffer to support a variety of standards please see TN1177, LatticeECP3 sysIO Usage Guide. 2-42 Architecture LatticeECP3 Family Data Sheet On-Chip Programmable Termination The LatticeECP3 supports a variety of programmable on-chip terminations options, including: * Dynamically switchable Single-Ended Termination with programmable resistor values of 40, 50, or 60 ohms. External termination to Vtt should be used for DDR2 and DDR3 memory controller implementation. * Common mode termination of 80, 100, 120 ohms for differential inputs Figure 2-39.

TERMINATE to VTT and DIFFRENTIAL TERMINATION RESISTOR when turned on can only have one setting per bank. Only left and right banks have this feature. Use of TERMINATE to VTT and DIFFRENTIAL TERMINATION RESISTOR are mutually exclusive in an I/O bank. On-chip termination tolerance +/- 20% 2. External termination to VTT should be used when implementing DDR2 and DDR3 memory controller. 2-43 Architecture LatticeECP3 Family Data Sheet Please see TN1177, LatticeECP3 sysIO Usage Guide for on-chip termination usage and value ranges. Equalization Filter Equalization filtering is available for single-ended inputs on both true and complementary I/Os, and for differential inputs on the true I/Os on the left, right, and top sides. Equalization is required to compensate for the difficulty of sampling alternating logic transitions with a relatively slow slew rate. It is considered the most useful for the Input DDRX2 modes, used in DDR3 memory, LVDS, or TRLVDS signaling. Equalization filter acts as a tunable filter with settings to determine the level of correction. In the LatticeECP3 devices, there are four settings available: 0 (none), 1, 2 and 3. The default setting is 0. The equalization logic resides in the sysI/O buffers, the two bits of setting is set uniquely in each input IOLOGIC block. Therefore, each sysI/O can have a unique equalization setting within a DQS-12 group. Hot Socketing LatticeECP3 devices have been carefully designed to ensure predictable behavior during power-up and powerdown. During power-up and power-down sequences, the I/Os remain in tri-state until the power supply voltage is high enough to ensure reliable operation. In addition, leakage into I/O pins is controlled within specified limits. Please refer to the Hot Socketing Specifications in the DC and Switching Characteristics in this data sheet. SERDES and PCS (Physical Coding Sublayer) LatticeECP3 devices feature up to 16 channels of embedded SERDES/PCS arranged in quads at the bottom of the devices supporting up to 3.2Gbps data rate. Figure 2-40 shows the position of the quad blocks for the LatticeECP3150 devices. Table 2-14 shows the location of available SERDES Quads for all devices. The LatticeECP3 SERDES/PCS supports a range of popular serial protocols, including: * PCI Express 1.1 * Ethernet (XAUI, GbE - 1000 Base CS/SX/LX and SGMII) * Serial RapidIO * SMPTE SDI (3G, HD, SD) * CPRI * SONET/SDH (STS-3, STS-12, STS-48) Each quad contains four dedicated SERDES for high speed, full duplex serial data transfer. Each quad also has a PCS block that interfaces to the SERDES channels and contains protocol specific digital logic to support the standards listed above. The PCS block also contains interface logic to the FPGA fabric. All PCS logic for dedicated protocol support can also be bypassed to allow raw 8-bit or 10-bit interfaces to the FPGA fabric. Even though the SERDES/PCS blocks are arranged in quads, multiple baud rates can be supported within a quad with the use of dedicated, per channel 1, 2 and 11 rate dividers. Additionally, multiple quads can be arranged together to form larger data pipes. For information on how to use the SERDES/PCS blocks to support specific protocols, as well on how to combine multiple protocols and baud rates within a device, please refer to TN1176, LatticeECP3 SERDES/PCS Usage Guide. 2-44 Architecture LatticeECP3 Family Data Sheet Figure 2-40.

The SERDES transmitter channel may receive the parallel 8- or 10-bit data, serialize the data and transmit the serial bit stream through the differential drivers. Figure 2-41 shows a single-channel SERDES/PCS block. Each SERDES channel provides a recovered clock and a SERDES transmit clock to the PCS block and to the FPGA core logic. Each transmit channel, receiver channel, and SERDES PLL shares the same power supply (VCCA). The output and input buffers of each channel have their own independent power supplies (VCCOB and VCCIB).

For the transmit channel, the PCS block receives the parallel data from the FPGA core, encodes it with 8b/10b, selects the polarity and passes the 8/10 bit data to the transmit SERDES channel. The PCS also provides bypass modes that allow a direct 8-bit or 10-bit interface from the SERDES to the FPGA logic. The PCS interface to the FPGA can also be programmed to run at 1/2 speed for a 16-bit or 20-bit interface to the FPGA logic. SCI (SERDES Client Interface) Bus The SERDES Client Interface (SCI) is an IP interface that allows the SERDES/PCS Quad block to be controlled by registers rather than the configuration memory cells. It is a simple register configuration interface that allows SERDES/PCS configuration without power cycling the device. 2-46 Architecture LatticeECP3 Family Data Sheet The Diamond and ispLEVER design tools support all modes of the PCS. Most modes are dedicated to applications associated with a specific industry standard data protocol. Other more general purpose modes allow users to define their own operation. With these tools, the user can define the mode for each quad in a design. Popular standards such as 10Gb Ethernet, x4 PCI Express and 4x Serial RapidIO can be implemented using IP (available through Lattice), a single quad (Four SERDES channels and PCS) and some additional logic from the core. The LatticeECP3 family also supports a wide range of primary and secondary protocols. Within the same quad, the LatticeECP3 family can support mixed protocols with semi-independent clocking as long as the required clock frequencies are integer x1, x2, or x11 multiples of each other. Table 2-15 lists the allowable combination of primary and secondary protocol combinations. Flexible Quad SERDES Architecture The LatticeECP3 family SERDES architecture is a quad-based architecture. For most SERDES settings and standards, the whole quad (consisting of four SERDES) is treated as a unit. This helps in silicon area savings, better utilization and overall lower cost. However, for some specific standards, the LatticeECP3 quad architecture provides flexibility; more than one standard can be supported within the same quad. Table 2-15 shows the standards can be mixed and matched within the same quad. In general, the SERDES standards whose nominal data rates are either the same or a defined subset of each other, can be supported within the same quad. In Table 2-15, the Primary Protocol column refers to the standard that determines the reference clock and PLL settings. The Secondary Protocol column shows the other standard that can be supported within the same quad. Furthermore, Table 2-15 also implies that more than two standards in the same quad can be supported, as long as they conform to the data rate and reference clock requirements. For example, a quad may contain PCI Express 1.1, SGMII, Serial RapidIO Type I and Serial RapidIO Type II, all in the same quad. Table 2-15. LatticeECP3 Primary and Secondary Protocol Support Primary Protocol Secondary Protocol PCI Express 1.1 SGMII PCI Express 1.1 Gigabit Ethernet PCI Express 1.1 Serial RapidIO Type I PCI Express 1.1 Serial RapidIO Type II Serial RapidIO Type I SGMII Serial RapidIO Type I Gigabit Ethernet Serial RapidIO Type II SGMII Serial RapidIO Type II Gigabit Ethernet Serial RapidIO Type II Serial RapidIO Type I CPRI-3 CPRI-2 and CPRI-1 3G-SDI HD-SDI and SD-SDI There are some restrictions to be aware of when using spread spectrum. When a quad shares a PCI Express x1 channel with a non-PCI Express channel, ensure that the reference clock for the quad is compatible with all protocols within the quad. For example, a PCI Express spread spectrum reference clock is not compatible with most Gigabit Ethernet applications because of tight CTC ppm requirements. While the LatticeECP3 architecture will allow the mixing of a PCI Express channel and a Gigabit Ethernet, Serial RapidIO or SGMII channel within the same quad, using a PCI Express spread spectrum clocking as the transmit 2-47 Architecture LatticeECP3 Family Data Sheet reference clock will cause a violation of the Gigabit Ethernet, Serial RapidIO and SGMII transmit jitter specifications. For further information on SERDES, please see TN1176, LatticeECP3 SERDES/PCS Usage Guide. IEEE 1149.1-Compliant Boundary Scan Testability All LatticeECP3 devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant Test Access Port (TAP). This allows functional testing of the circuit board on which the device is mounted through a serial scan path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in and loaded directly onto test nodes, or test data to be captured and shifted out for verification. The test access port consists of dedicated I/Os: TDI, TDO, TCK and TMS. The test access port has its own supply voltage VCCJ and can operate with LVCMOS3.3, 2.5, 1.8, 1.5 and 1.2 standards. For more information, please see TN1169, LatticeECP3 sysCONFIG Usage Guide. Device Configuration All LatticeECP3 devices contain two ports that can be used for device configuration. The Test Access Port (TAP), which supports bit-wide configuration, and the sysCONFIG port, support dual-byte, byte and serial configuration. The TAP supports both the IEEE Standard 1149.1 Boundary Scan specification and the IEEE Standard 1532 InSystem Configuration specification. The sysCONFIG port includes seven I/Os used as dedicated pins with the remaining pins used as dual-use pins. See TN1169, LatticeECP3 sysCONFIG Usage Guide for more information about using the dual-use pins as general purpose I/Os. There are various ways to configure a LatticeECP3 device: 1. JTAG 2. Standard Serial Peripheral Interface (SPI and SPIm modes) - interface to boot PROM memory 3. System microprocessor to drive a x8 CPU port (PCM mode) 4. System microprocessor to drive a serial slave SPI port (SSPI mode) 5. Generic byte wide flash with a MachXOTM device, providing control and addressing On power-up, the FPGA SRAM is ready to be configured using the selected sysCONFIG port. Once a configuration port is selected, it will remain active throughout that configuration cycle. The IEEE 1149.1 port can be activated any time after power-up by sending the appropriate command through the TAP port. LatticeECP3 devices also support the Slave SPI Interface. In this mode, the FPGA behaves like a SPI Flash device (slave mode) with the SPI port of the FPGA to perform read-write operations. Enhanced Configuration Options LatticeECP3 devices have enhanced configuration features such as: decryption support, TransFRTM I/O and dualboot image support. 1. TransFR (Transparent Field Reconfiguration) TransFR I/O (TFR) is a unique Lattice technology that allows users to update their logic in the field without interrupting system operation using a single ispVM command. TransFR I/O allows I/O states to be frozen during device configuration. This allows the device to be field updated with a minimum of system disruption and downtime. See TN1087, Minimizing System Interruption During Configuration Using TransFR Technology for details. 2. Dual-Boot Image Support Dual-boot images are supported for applications requiring reliable remote updates of configuration data for the 2-48 Architecture LatticeECP3 Family Data Sheet system FPGA. After the system is running with a basic configuration, a new boot image can be downloaded remotely and stored in a separate location in the configuration storage device. Any time after the update the LatticeECP3 can be re-booted from this new configuration file. If there is a problem, such as corrupt data during download or incorrect version number with this new boot image, the LatticeECP3 device can revert back to the original backup golden configuration and try again. This all can be done without power cycling the system. For more information, please see TN1169, LatticeECP3 sysCONFIG Usage Guide. Soft Error Detect (SED) Support LatticeECP3 devices have dedicated logic to perform Cycle Redundancy Code (CRC) checks. During configuration, the configuration data bitstream can be checked with the CRC logic block. In addition, the LatticeECP3 device can also be programmed to utilize a Soft Error Detect (SED) mode that checks for soft errors in configuration SRAM. The SED operation can be run in the background during user mode. If a soft error occurs, during user mode (normal operation) the device can be programmed to generate an error signal. For further information on SED support, please see TN1184, LatticeECP3 Soft Error Detection (SED) Usage Guide. External Resistor LatticeECP3 devices require a single external, 10K ohm 1% value between the XRES pin and ground. Device configuration will not be completed if this resistor is missing. There is no boundary scan register on the external resistor pad. On-Chip Oscillator Every LatticeECP3 device has an internal CMOS oscillator which is used to derive a Master Clock (MCCLK) for configuration. The oscillator and the MCCLK run continuously and are available to user logic after configuration is completed. The software default value of the MCCLK is nominally 2.5MHz. Table 2-16 lists all the available MCCLK frequencies. When a different Master Clock is selected during the design process, the following sequence takes place: 1. Device powers up with a nominal Master Clock frequency of 3.1MHz. 2. During configuration, users select a different master clock frequency. 3. The Master Clock frequency changes to the selected frequency once the clock configuration bits are received. 4. If the user does not select a master clock frequency, then the configuration bitstream defaults to the MCCLK frequency of 2.5MHz. This internal 130 MHz +/- 15% CMOS oscillator is available to the user by routing it as an input clock to the clock tree. For further information on the use of this oscillator for configuration or user mode, please see TN1169, LatticeECP3 sysCONFIG Usage Guide. Table 2-16.

Maximum MCCLK without encryption. 2-49 Architecture LatticeECP3 Family Data Sheet Density Shifting The LatticeECP3 family is designed to ensure that different density devices in the same family and in the same package have the same pinout. Furthermore, the architecture ensures a high success rate when performing design migration from lower density devices to higher density devices. In many cases, it is also possible to shift a lower utilization design targeted for a high-density device to a lower density device. However, the exact details of the final resource utilization will impact the likelihood of success in each case. An example is that some user I/Os may become No Connects in smaller devices in the same package. Refer to the LatticeECP3 Pin Migration Tables and Diamond software for specific restrictions and limitations. 2-50 LatticeECP3 Family Data Sheet DC and Switching Characteristics September 2013 Data Sheet DS1021 Absolute Maximum Ratings1, 2, 3 Supply Voltage VCC . . . . . . . . . . . . . . . . . . . -0.5 to 1.32V Supply Voltage VCCAUX . . . . . . . . . . . . . . . . -0.5 to 3.75V Supply Voltage VCCJ . . . . . . . . . . . . . . . . . . -0.5 to 3.75V Output Supply Voltage VCCIO . . . . . . . . . . . -0.5 to 3.75V Input or I/O Tristate Voltage Applied4 . . . . . . -0.5 to 3.75V Storage Temperature (Ambient) . . . . . . . . . -65 to 150C Junction Temperature (TJ) . . . . . . . . . . . . . . . . . . +125C 1.

Input Data Jitter Tolerance A receiver's ability to tolerate incoming signal jitter is very dependent on jitter type. High speed serial interface standards have recognized the dependency on jitter type and have specifications to indicate tolerance levels for different jitter types as they relate to specific protocols.
