The AP domain is built around an ARM1136JF-S core with 16-Kbyte instruction and data L1 caches, an MMU, a 128-Kbyte L2 cache, a multiported crossbar switch, and advanced debug and trace interfaces. i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 5 The i.MX35 core is intended to operate at a maximum frequency of 532 MHz to support the required multimedia use cases. Furthermore, an image processing unit (IPU) is integrated into the AP domain to offload the ARM11 core from performing functions such as color space conversion, image rotation and scaling, graphics overlay, and pre- and post-processing. The functionality of AP Domain peripherals includes the user interface; the connectivity, display, security, and memory interfaces; and 128 Kbytes of multipurpose SRAM. 2.2 Shared Domain Overview The shared domain is composed of the shared peripherals, a smart DMA engine (SDMA) and a number of miscellaneous modules. For maximum flexibility, some peripherals are directly accessible by the SDMA engine. The i.MX35 has a hierarchical memory architecture including L1 caches and a unified L2 cache. This reduces the bandwidth demands for the external bus and external memory. The external memory subsystem supports a flexible external memory system, including support for SDRAM (SDR, DDR2 and mobile DDR) and NAND Flash. 2.3 Advanced Power Management Overview To address the continuing need to reduce power consumption, the following techniques are incorporated in the i.MX35: * Clock gating * Power gating * Power-optimized synthesis * Well biasing The insertion of gating into the clock paths allows unused portions of the chip to be disabled. Because static CMOS logic consumes only leakage power, significant power savings can be realized. "Well biasing" is applying a voltage that is greater than VDD to the nwells, and one that is lower than VSS to the pwells. The effect of applying this well back bias voltage reduces the subthreshold channel leakage. For the 90-nm digital process, it is estimated that the subthreshold leakage is reduced by a factor of ten over the nominal leakage. Additionally, the supply voltage for internal logic can be reduced from 1.4 V to 1.22 V. 2.4 ARM11 Microprocessor Core The CPU of the i.MX35 is the ARM1136JF-S core, based on the ARM v6 architecture.

For example, if using SDRAM then NVCC_EMI1,2,3 should all be set at 3.3 V (typ.). If using MDDR or DDR2, NVC_EMI1,2,3 must be set at 1.8 V (typ.). 2 MLB interface I/O pads can be programmed to function as GPIO by setting NVCC_MLB to 1.8 or 3.3 V, but if used as MLB pads, NVCC_MLB must be set to 2.5 V in order to be compliant with external MOST devices. NVCC_MLB may be left floating. 3 The Fusebox read supply is connected to supply of the full speed USB PHY. FUSE_VDD is only used for programming. It is recommended that FUSE_VDD be connected to ground when not being used for programming. FUSE_VDD should be supplied by following the power up sequence given in Section 4.3.1, "Powering Up." i.MX35 Applications Processors for Automotive Products, Rev. 10 14 Freescale Semiconductor 4.1.2 Interface Frequency Limits Table 9 provides information on interface frequency limits.

CAUTION Any i.MX35 board design must comply with the power-up and power-down sequence guidelines as described in this section to guarantee reliable operation of the device. Any deviation from these sequences can result in irreversible damage to the i.MX35 processor (worst-case scenario). i.MX35 Applications Processors for Automotive Products, Rev. 10 16 Freescale Semiconductor NOTE Deviation from these sequences may also result in one or more of the following: * * * 4.3.1 Excessive current during power-up phase Prevent the device from booting Programming of unprogrammed fuses Powering Up The power-up sequence should be completed as follows: 1. Assert Power on Reset (POR). 2. Turn on digital logic domain and IO power supply: VDDn, NVCCx 3. Wait until VDDn and NVCCx power supplies are stable + 32 s. 4. Turn on all other power supplies: PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD, USBPHY1_UPLLVDD, OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, FUSEVDD. (Always FUSE_VDD should be connected to ground, except when eFuses are to be programmed.) 5. Wait until PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD, USBPHY1_UPLLVDD, OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, (FUSEVDD, optional). Power supplies are stable + 100 s. 6. Deassert the POR signal. i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 17 Figure 2 shows the power-up sequence and timing. Figure 2. i.MX35 Power-Up Sequence and Timing 4.3.2 Powering Down The power-up sequence in reverse order is recommended for powering down. However, all power supplies can be shut down at the same time. 4.4 Reset Timing There are two ways of resetting the i.MX35 using external pins: * Power On Reset (using the POR_B pin) * System Reset (using the RESET_IN_B pin) 4.4.1 Power On Reset POR_B is normally connected to a power management integrated circuit (PMIC). The PMIC asserts POR_B while the power supplies are turned on and negates POR_B after the power up sequence is finished. See Figure 2. i.MX35 Applications Processors for Automotive Products, Rev. 10 18 Freescale Semiconductor Assuming the i.MX35 chip is already fully powered; it is still possible to reset all of the modules to their default reset by asserting POR_B for at least 4 CKIL cycles and later de-asserting POR_B. This method of resetting the i.MX35 can also be supported by tying the POR_B and RESET_IN_B pins together. POR_B At least 4 CKIL cycles CKIL Figure 3. Timing Between POR_B and CKIL for Complete Reset of i.MX35 4.4.2 System Reset System reset can be achieved by asserting RESET_IN_B for at least 4 CKIL cycles and later negating RESET_IN_B. The following modules are not reset upon system reset: RTC, PLLs, CCM, and IIM. POR_B pin must be deasserted all the time. RESET_IN_B At least 4 CKIL cycles CKIL Figure 4. Timing Between RESET_IN_B and CKIL for i.MX35 System Reboot 4.5 Power Characteristics The table shows values representing maximum current numbers for the i.MX35 under worst case voltage and temperature conditions. These values are derived from the i.MX35 with core clock speeds up to 532 MHz. Common supplies have been bundled according to the i.MX35 power-up sequence requirements. Peak numbers are provided for system designers so that the i.MX35 power supply requirements will be satisfied during startup and transient conditions. Freescale recommends that system current measurements be taken with customer-specific use-cases to reflect normal operating conditions in the end system. i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 19 Table 11.

FUSE_VDD should be supplied by following the power up sequence given in Section 4.3.1, "Powering Up." The method for obtaining max current is as follows: 1. Measure worst case power consumption on individual rails using directed test on i.MX35. 2. Correlate worst case power consumption power measurements with worst case power consumption simulations. 3. Combine common voltage rails based on power supply sequencing requirements 4. Guard band worst case numbers for temperature and process variation. Guard band is based on process data and correlated with actual data measured on i.MX35. 5. The sum of individual rails is greater than real world power consumption, as a real system does not typically maximize power consumption on all peripherals simultaneously. 4.6 Thermal Characteristics The thermal resistance characteristics for the device are given in Table 12. These values were measured under the following conditions: * Two-layer substrate * Substrate solder mask thickness: 0.025 mm * Substrate metal thicknesses: 0.016 mm * Substrate core thickness: 0.200 mm * Core via I.D: 0.168 mm, Core via plating 0.016 mm. * Full array map design, but nearly all balls under die are power or ground. * Die Attach: 0.033 mm non-conductive die attach, k = 0.3 W/m K * Mold compound: k = 0.9 W/m K Table 12.

When Greek letters are not available, this thermal characterization parameter is written as Psi-JT. 4.7 I/O Pin DC Electrical Characteristics I/O pins are of two types: GPIO and DDR. DDR pins can be configured in three different drive strength modes: mobile DDR, SDRAM, and DDR2. The SDRAM and mobile DDR modes can be further customized at three drive strength levels: normal, high, and max. Table 13 shows currents for the different DDR pin drive strength modes. Table 13.

The i.MX35 has two CAN modules available for systems design. Tx and Rx ports for both modules are multiplexed with other I/O pins.

The maximum hold time has to be met only if the device does not stretch the LOW period (ID IC6) of the I2CLK signal. A fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement of set-up time (ID IC7) of 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the I2CLK signal. If such a device does stretch the LOW period of the I2CLK signal, it must output the next data bit to the I2DAT line max_rise_time (ID No IC10) + data_setup_time (ID No IC8) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the I2CLK line is released. i.MX35 Applications Processors for Automotive Products, Rev. 10 66 Freescale Semiconductor 4.9.12 IPU--Sensor Interfaces This section contains a list of supported camera sensors, a functional description, and the electrical characteristics. 4.9.12.1 Supported Camera Sensors Table 53 lists the known supported camera sensors at the time of publication.

These sensors have not been validated at the time of publication. 4.9.12.2 Functional Description There are three timing modes supported by the IPU. 4.9.12.2.1 Pseudo BT.656 Video Mode Smart camera sensors, which typically include image processing capability, support video mode transfer operations. They use an embedded timing syntax to replace the SENSB_VSYNC and SENSB_HSYNC signals. The timing syntax is defined by the BT.656 standard. This operation mode follows the recommendations of the ITU BT.656 specifications. The only control signal used is SENSB_PIX_CLK. Start-of-frame and active-line signals are embedded in the data stream. An active line starts with a SAV code and ends with an EAV code. In some cases, digital blanking is i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 67 inserted in between EAV and SAV code. The CSI decodes and filters out the timing coding from the data stream, thus recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use. 4.9.12.2.2 Gated Clock Mode The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See Figure 44. Active Line Start of Frame nth frame n+1th frame SENSB_VSYNC SENSB_HSYNC SENSB_PIX_CLK invalid SENSB_DATA[9:0] invalid 1st byte 1st byte Figure 44. Gated Clock Mode Timing Diagram A frame starts with a rising edge on SENSB_VSYNC (all the timing corresponds to straight polarity of the corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. The pixel clock is valid as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks. SENSB_HSYNC goes to low at the end of the line. Pixel clocks then become invalid and the CSI stops receiving data from the stream. For the next line, the SENSB_HSYNC timing repeats. For the next frame, the SENSB_VSYNC timing repeats. 4.9.12.2.3 Non-Gated Clock Mode The timing is the same as the gated-clock mode (described in Section 4.9.12.2.2, "Gated Clock Mode"), except for the SENSB_HSYNC signal, which is not used. See Figure 45. All incoming pixel clocks are valid and will cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states low) until valid data is going to be transmitted over the bus. Start of Frame nth frame n+1th frame SENSB_VSYNC SENSB_PIX_CLK SENSB_DATA[7:0] invalid invalid 1st byte 1st byte Figure 45. Non-Gated Clock Mode Timing Diagram i.MX35 Applications Processors for Automotive Products, Rev. 10 68 Freescale Semiconductor The timing described in Figure 45 is that of a Motorola sensor. Some other sensors may have slightly different timing. The CSI can be programmed to support rising/falling-edge triggered SENSB_VSYNC; active-high/low SENSB_HSYNC; and rising/falling-edge triggered SENSB_PIX_CLK. 4.9.12.3 Electrical Characteristics Figure 46 depicts the sensor interface timing, and Table 54 lists the timing parameters. 1/IP1 SENSB_MCLK (Sensor Input) SENSB_PIX_CLK (Sensor Output) IP3 IP2 1/IP4 SENSB_DATA, SENSB_VSYNC, SENSB_HSYNC Figure 46.

In this figure, signals are shown with negative polarity. The sequence of events for active matrix interface timing is as follows: * DISPB_D3_CLK latches data into the panel on its negative edge (when positive polarity is selected). In active mode, DISPB_D3_CLK runs continuously. * DISPB_D3_HSYNC causes the panel to start a new line. * DISPB_D3_VSYNC causes the panel to start a new frame. It always encompasses at least one HSYNC pulse. * DISPB_D3_DRDY acts like an output enable signal to the CRT display. This output enables the data to be shifted to the display. When disabled, the data is invalid and the trace is off.

See Section 4.9.13.1.5, "Interface to Active Matrix TFT LCD Panels, Electrical Characteristics." 4.9.13.3.6 Interface to a TV Encoder--Functional Description The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The bits D7-D0 of the value are mapped to bits LD17-LD10 of the data bus, respectively. Figure 52 depicts the interface timing. * The frequency of the clock DISPB_D3_CLK is 27 MHz. * The DISPB_D3_HSYNC, DISPB_D3_VSYNC and DISPB_D3_DRDY signals are active low. * The transition to the next row is marked by the negative edge of the DISPB_D3_HSYNC signal. It remains low for a single clock cycle. * The transition to the next field/frame is marked by the negative edge of the DISPB_D3_VSYNC signal. It remains low for at least one clock cycle. -- At a transition to an odd field (of the next frame), the negative edges of DISPB_D3_VSYNC and DISPB_D3_HSYNC coincide. -- At a transition to an even field (of the same frame), they do not coincide. * The active intervals--during which data is transferred--are marked by the DISPB_D3_HSYNC signal being high. i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 75 DISPB_D3_CLK DISPB_D3_HSYNC DISPB_D3_VSYNC DISPB_D3_DRDY DISPB_DATA Cb Y Cr Y Cb Y Cr Pixel Data Timing DISPB_D3_HSYNC 524 523 525 2 1 3 5 4 6 10 DISPB_D3_DRDY DISPB_D3_VSYNC Even Field 261 262 Odd Field 263 264 265 266 267 268 269 273 DISPB_D3_HSYNC DISPB_D3_DRDY DISPB_D3_VSYNC Even Field Odd Field Line and Field Timing - NTSC DISPB_D3_HSYNC 621 622 623 624 625 1 3 2 4 23 DISPB_D3_DRDY DISPB_D3_VSYNC Even Field 308 309 Odd Field 310 311 312 313 314 315 316 336 DISPB_D3_HSYNC DISPB_D3_DRDY DISPB_D3_VSYNC Even Field Odd Field Line and Field Timing - PAL Figure 52. TV Encoder Interface Timing Diagram i.MX35 Applications Processors for Automotive Products, Rev. 10 76 Freescale Semiconductor 4.9.13.3.7 Interface to a TV Encoder, Electrical Characteristics The timing characteristics of the TV encoder interface are identical to the synchronous display characteristics. See Section 4.9.13.1.5, "Interface to Active Matrix TFT LCD Panels, Electrical Characteristics." 4.9.13.4 Asynchronous Interfaces This section discusses the asynchronous parallel and serial interfaces. 4.9.13.4.8 Parallel Interfaces, Functional Description The IPU supports the following asynchronous parallel interfaces: * System 80 interface -- Type 1 (sampling with the chip select signal) with and without byte enable signals. -- Type 2 (sampling with the read and write signals) with and without byte enable signals. * System 68k interface -- Type 1 (sampling with the chip select signal) with or without byte enable signals. -- Type 2 (sampling with the read and write signals) with or without byte enable signals. For each of four system interfaces, there are three burst modes: 1. Burst mode without a separate clock--The burst length is defined by the corresponding parameters of the IDMAC (when data is transferred from the system memory) or by the HBURST signal (when the MCU directly accesses the display via the slave AHB bus). For system 80 and system 68k type 1 interfaces, data is sampled by the CS signal and other control signals change only when transfer direction is changed during the burst. For type 2 interfaces, data is sampled by the WR/RD signals (system 80) or by the ENABLE signal (system 68k), and the CS signal stays active during the whole burst. 2. Burst mode with the separate clock DISPB_BCLK--In this mode, data is sampled with the DISPB_BCLK clock. The CS signal stays active during whole burst transfer. Other controls are changed simultaneously with data when the bus state (read, write or wait) is altered. The CS signals and other controls move to non-active state after burst has been completed. 3. Single access mode--In this mode, slave AHB and DMA burst are broken to single accesses. The data is sampled with CS or other controls according to the interface type as described above. All controls (including CS) become non-active for one display interface clock after each access. This mode corresponds to the ATI single access mode. Both system 80 and system 68k interfaces are supported for all described modes as depicted in Figure 53, Figure 54, Figure 55, and Figure 56. These timing images correspond to active-low DISPB_Dn_CS, DISPB_Dn_WR and DISPB_Dn_RD signals. i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 77 Additionally, the IPU allows a programmable pause between two bursts. The pause is defined in the HSP_CLK cycles. It allows the prevention of timing violation between two sequential bursts or two accesses to different displays. The range of this pause is from 4 to 19 HSP_CLK cycles.

The timing images correspond to active-low DISPB_D#_CS signal and the straight polarity of the DISPB_SD_D_CLK signal. For this interface, a bidirectional data line is used outside the device. The IPU still uses separate input and output data lines (IPP_IND_DISPB_SD_D and IPP_DO_DISPB_SD_D). The I/O mux connects the internal data lines to the bidirectional external line according to the IPP_OBE_DISPB_SD_D signal provided by the IPU. Each data transfer can be preceded by an optional preamble with programmable length and contents. The preamble is followed by read/write (RW) and address (RS) bits. The order of the these bits is programmable. The RW bit can be disabled. The following data can consist of one word or of a whole burst. The interface parameters are controlled by the DI_SER_DISPn_CONF registers (n = 1, 2). i.MX35 Applications Processors for Automotive Products, Rev. 10 88 Freescale Semiconductor DISPB_D#_CS 1 display IF clock cycle 1 display IF clock cycle DISPB_SD_D_CLK DISPB_SD_D RW RS D7 D6 D5 D4 D3 D2 D1 D0 Input or output data Preamble Figure 62. 3-Wire Serial Interface Timing Diagram Figure 63 depicts timing of the 4-wire serial interface.

Each transfer mode has a different data transfer rate, Ultra DMA mode 4 data transfer rate is up to 100 MBps. The parallel ATA module interface consists of a total of 29 pins. Some pins have different functions in different transfer modes. There are various requirements for timing relationships among the function pins, in compliance with the ATA/ATAPI-6 specification, and these requirements are configurable by the ATA module registers. 4.9.17.1 General Timing Requirements Table 67 and Figure 74 define the AC characteristics of the interface signals on all data transfer modes.

ATA Interface Signals SI2 SI1 Figure 74. ATA Interface Signals Timing Diagram 4.9.17.2 ATA Electrical Specifications (ATA Bus, Bus Buffers) This section discusses ATA parameters. For a detailed description, refer to the ATA-6 specification. Level shifters are required for 3.3-V or 5.0-V compatibility on the ATA interface. The use of bus buffers introduces delays on the bus and introduces skew between signal lines. These factors make it difficult to operate the bus at the highest speed (UDMA-5) when bus buffers are used. Use of bus buffers is not recommended if fast UDMA mode is required. The ATA specification imposes a slew rate limit on the ATA bus. According to this limit, any signal driven on the bus should have a slew rate between 0.4 and 1.2 V/ns with a 40 pF load. Few vendors of bus buffers specify the slew rate of the outgoing signals. When bus buffers are used the ata_data bus buffer is bidirectional, and uses the direction control signal ata_buffer_en. When ata_buffer_en is asserted, the bus should drive from host to device. When i.MX35 Applications Processors for Automotive Products, Rev. 10 Freescale Semiconductor 101 ata_buffer_en is negated, the bus drives from device to host. Steering of the signal is such that contention on the host and device tri-state buses is always avoided. 4.9.17.3 Timing Parameters Table 68 shows the parameters used in the timing equations. These parameters depend on the implementation of the ATA interface on silicon, the bus buffer used, the cable delay, and the cable skew. Table 68.
