Introduction

iCE40 LP/HX Family Data Sheet

Table 1-1. iCE40 Family Selection Guide (continued)

Introduction

The iCE40 family of ultra-low power, non-volatile FPGAs has five devices with densities ranging from 384 to 7680

Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic, these devices feature Embedded

Block RAM (EBR), Non-volatile Configuration Memory (NVCM) and Phase Locked Loops (PLLs). These features

allow the devices to be used in low-cost, high-volume consumer and system applications. Select packages offer

High-Current drivers that are ideal to drive three white LEDs, or one RGB LED.

The iCE40 devices are fabricated on a 40 nm CMOS low power process. The device architecture has several fea-

tures such as programmable low-swing differential I/Os and the ability to turn off on-chip PLLs dynamically. These

features help manage static and dynamic power consumption, resulting in low static power for all members of the

family. The iCE40 devices are available in two versions – ultra low power (LP) and high performance (HX) devices.

The iCE40 FPGAs are available in a broad range of advanced halogen-free packages ranging from the space

saving 1.40x1.48mm WLCSP to the PCB-friendly 20x20 mm TQFP. Table 1-1 shows the LUT densities, package

and I/O options, along with other key parameters.

The iCE40 devices offer enhanced I/O features such as pull-up resistors. Pull-up features are controllable on a

“per-pin” basis.

The iCE40 devices also provide flexible, reliable and secure configuration from on-chip NVCM. These devices can

also configure themselves from external SPI Flash or be configured by an external master such as a CPU.

Lattice provides a variety of design tools that allow complex designs to be efficiently implemented using the iCE40

family of devices. Popular logic synthesis tools provide synthesis library support for iCE40. Lattice design tools use

the synthesis tool output along with the user-specified preferences and constraints to place and route the design in

the iCE40 device. These tools extract the timing from the routing and back-annotate it into the design for timing ver-

ification.

Lattice provides many pre-engineered IP (Intellectual Property) modules, including a number of reference designs,

licensed free of charge, optimized for the iCE40 FPGA family. By using these configurable soft core IP cores as

standardized blocks, users are free to concentrate on the unique aspects of their design, increasing their productiv-

ity.

Architecture Overview

The iCE40 family architecture contains an array of Programmable Logic Blocks (PLB), sysCLOCK™ PLLs, Non-

volatile Programmable Configuration Memory (NVCM) and blocks of sysMEM™ Embedded Block RAM (EBR) sur-

rounded by Programmable I/O (PIO). Figure 2-1 shows the block diagram of the iCE40LP/HX1K device.

Figure 2-1. iCE40LP/HX1K Device, Top View

The logic blocks, Programmable Logic Blocks (PLB) and sysMEM EBR blocks, are arranged in a two-dimensional

grid with rows and columns. Each column has either logic blocks or EBR blocks. The PIO cells are located at the

periphery of the device, arranged in banks. The PLB contains the building blocks for logic, arithmetic, and register

functions. The PIOs utilize a flexible I/O buffer referred to as a sysIO buffer that supports operation with a variety of

interface standards. The blocks are connected with many vertical and horizontal routing channel resources. The

place and route software tool automatically allocates these routing resources.

In the iCE40 family, there are up to four independent sysIO banks. Note on some packages VCCIO banks are tied

together. There are different types of I/O buffers on the different banks. Refer to the details in later sections of this

document. The sysMEM EBRs are large 4 Kbit, dedicated fast memory blocks. These blocks can be configured as

RAM, ROM or FIFO.

The iCE40 architecture also provides up to two sysCLOCK Phase Locked Loop (PLL) blocks. The PLLs have mul-

tiply, divide, and phase shifting capabilities that are used to manage the frequency and phase relationships of the

clocks.

Every device in the family has a SPI port that supports programming and configuration of the device. The iCE40

includes on-chip, Nonvolatile Configuration Memory (NVCM).

PLB Blocks

The core of the iCE40 device consists of Programmable Logic Blocks (PLB) which can be programmed to perform

logic and arithmetic functions. Each PLB consists of eight interconnected Logic Cells (LC) as shown in Figure 2-2.

Each LC contains one LUT and one register.

Figure 2-2. PLB Block Diagram

Logic Cells

Each Logic Cell includes three primary logic elements shown in Figure 2-2.

• A four-input Look-Up Table (LUT4) builds any combinational logic function, of any complexity, requiring up to

four inputs. Similarly, the LUT4 element behaves as a 16x1 Read-Only Memory (ROM). Combine and cas-

cade multiple LUT4s to create wider logic functions.

• A ‘D’-style Flip-Flop (DFF), with an optional clock-enable and reset control input, builds sequential logic func-

tions. Each DFF also connects to a global reset signal that is automatically asserted immediately following

device configuration.

• Carry Logic boosts the logic efficiency and performance of arithmetic functions, including adders, subtracters,

comparators, binary counters and some wide, cascaded logic functions.

Routing

There are many resources provided in the iCE40 devices to route signals individually with related control signals.

The routing resources consist of switching circuitry, buffers and metal interconnect (routing) segments.

The inter-PLB connections are made with three different types of routing resources: Adjacent (spans two PLBs), x4

(spans five PLBs) and x12 (spans thirteen PLBs). The Adjacent, x4 and x12 connections provide fast and efficient

connections in the diagonal, horizontal and vertical directions.

The design tool takes the output of the synthesis tool and places and routes the design.

Clock/Control Distribution Network

Each iCE40 device has eight global inputs, two pins on each side of the device. Note that not all GBINs are avail-

able in all packages.

These global inputs can be used as high fanout nets, clock, reset or enable signals. The dedicated global pins are

identified as GBIN[7:0] and the global buffers are identified as-GBUF[7:0]. These eight inputs may be used as gen-

eral purpose I/O if they are not used to drive the clock nets. Global buffer GBUF7 in I/O Bank 3 also provides an

optional direct LVDS25 or subLVDS differential clock input.

Table 2-2 lists the connections between a specific global buffer and the inputs on a PLB. All global buffers optionally

connect to the PLB CLK input. Any four of the eight global buffers can drive logic inputs to a PLB. Even-numbered

global buffers optionally drive the Set/Reset input to a PLB. Similarly, odd-numbered buffers optionally drive the

PLB clock-enable input.

Table 2-2. Global Buffer (GBUF) Connections to Programmable Logic Blocks

The maximum frequency for the global buffers are shown in the iCE40 External Switching Characteristics tables

later in this document.

Global Hi-Z Control

The global high-impedance control signal, GHIZ, connects to all I/O pins on the iCE40 device. This GHIZ signal is

automatically asserted throughout the configuration process, forcing all user I/O pins into their high-impedance

state.

Global Reset Control

The global reset control signal connects to all PLB and PIO flip-flops on the iCE40 device. The global reset signal is

automatically asserted throughout the configuration process, forcing all flip-flops to their defined wake-up state. For

PLB flip-flops, the wake-up state is always reset, regardless of the PLB flip-flop primitive used in the application.

sysCLOCK Phase Locked Loops (PLLs)

The sysCLOCK PLLs provide the ability to synthesize clock frequencies. The iCE40 devices have one or more sys-

CLOCK PLLs. REFERENCECLK is the reference frequency input to the PLL and its source can come from an

external I/O pin or from internal routing. EXTFEEDBACK is the feedback signal to the PLL which can come from

internal routing or an external I/O pin. The feedback divider is used to multiply the reference frequency and thus

synthesize a higher frequency clock output.

The PLLOUT output has an output divider, thus allowing the PLL to generate different frequencies for each output.

The output divider can have a value from 1 to 6. The PLLOUT outputs can all be used to drive the iCE40 global

clock network directly or general purpose routing resources can be used.

The LOCK signal is asserted when the PLL determines it has achieved lock and de-asserted if a loss of lock is

detected. A block diagram of the PLL is shown in Figure 2-3.

The timing of the device registers can be optimized by programming a phase shift into the PLLOUT output clock

which will advance or delay the output clock with reference to the REFERENCECLK clock. This phase shift can be

either programmed during configuration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock

after a phase adjustment on the output used as the feedback source and not relock until the tLOCK parameter has

been satisfied.

For more details on the PLL, see TN1251, iCE40 sysCLOCK PLL Design and Usage Guide.

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.

Note the sysMEM Embedded Block RAM Memory address 0 cannot be initialized.

Memory Cascading

Larger and deeper blocks of RAM can be created using multiple EBR sysMEM Blocks.

sysIO

Buffer Banks

iCE40 devices have up to four I/O banks with independent Vccio rails with an additional configuration bank VCC_SPI

for the SPI I/Os.

Programmable I/O (PIO)

The programmable logic associated with an I/O is called a PIO. The individual PIO are connected to their respec-

tive sysIO buffers and pads. The PIOs are placed on all four sides of the device.

Figure 2-5. I/O Bank and Programmable I/O Cell

The PIO contains three blocks: an input register block, output register block iCEgate™ and tri-state register block.

To save power, the optional iCEgateTM latch can selectively freeze the state of individual, non-registered inputs

within an I/O bank. Note that the freeze signal is common to the bank. These blocks can operate in a variety of

modes along with the necessary clock and selection logic.

Input Register Block

The input register blocks for the PIOs on all edges contain registers that can be used to condition high-speed inter-

face signals before they are passed to the device core. In Generic DDR mode, two registers are used to sample the

data on the positive and negative edges of the system clock signal, creating two data streams.

Output Register Block

The output register block can optionally register signals from the core of the device before they are passed to the

sysIO buffers. In Generic DDR mode, two registers are used to capture the data on the positive and negative edge

of the system clock and then muxed creating one data stream.

Figure 2-6 shows the input/output register block for the PIOs.

sysIO Buffer

Each I/O is associated with a flexible buffer referred to as a sysIO buffer. These buffers are arranged around the

periphery of the device in groups referred to as banks. The sysIO buffers allow users to implement a wide variety of

standards that are found in today’s systems including LVCMOS and LVDS25.

High Current LED Drivers combine three sysIO buffers together. This allows for programmable drive strength. This

also allows for high current drivers that are ideal to drive three white LEDs, or one RGB LED. Each bank is capable

of supporting multiple I/O standards including single-ended LVCMOS buffers and differential LVDS25E output buf-

fers. Bank 3 additionally supports differential LVDS25 input buffers. Each sysIO bank has its own dedicated power

supply.

Typical I/O Behavior During Power-up

The internal power-on-reset (POR) signal is deactivated when VCC, VCCIO_2, VPP_2V5, and VCC_SPI have reached

the level defined in the Power-On-Reset Voltage table in the DC and Switching Characteristics section of this data

sheet. After the POR signal is deactivated, the FPGA core logic becomes active. It is the user’s responsibility to

ensure that all 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. The default configuration of the I/O pins in a device prior to config-

uration is tri-stated with a weak pull-up to VCCIO. The I/O pins will maintain the pre-configuration state until VCC and

VCCIO (for I/O banks containing configuration I/Os) have reached levels, at which time the I/Os will take on the soft-

ware user-configured settings only after a proper download/configuration. Unused IOs are automatically blocked

and the pullup termination is disabled.

Supported Standards

The iCE40 sysIO buffer supports both single-ended and differential input standards. The single-ended standard

supported is LVCMOS. The buffer supports the LVCMOS 1.8, 2.5, and 3.3V standards. The buffer has individually

configurable options for bus maintenance (weak pull-up or none). The High Current output buffer have individually

configurable options for drive strength.

Table 2-7 and Table 2-8 show the I/O standards (together with their supply and reference voltages) supported by

the iCE40 devices.

Non-Volatile Configuration Memory

All iCE40 devices provide a Non-Volatile Configuration Memory (NVCM) block which can be used to configure the

device.

iCE40 LP/HX Family Data Sheet

Power On Reset

iCE40 devices have power-on reset circuitry to monitor VCC, VCCIO_2, VPP_2V5, and VCC_SPI voltage levels during

power-up and operation. At power-up, the POR circuitry monitors VCC, VCCIO_2, VPP_2V5, and VCC_SPI (controls

configuration) voltage levels. It then triggers download from the on-chip NVCM or external Flash memory after

reaching the power-up levels specified in the Power-On-Reset Voltage table in the DC and Switching Characteris-

tics section of this data sheet. Before and during configuration, the I/Os are held in tri-state. I/Os are released to

user functionality once the device has finished configuration.

Programming and Configuration

This section describes the programming and configuration of the iCE40 family.

Device Programming

The NVCM memory can be programmed through the SPI port.

Device Configuration

There are various ways to configure the Configuration RAM (CRAM) including:

1. Internal NVCM Download

2. From a SPI Flash (Master SPI mode)

3. System microprocessor to drive a Serial Slave SPI port (SSPI mode)

Power Saving Options

iCE40 devices are available in two options for maximum flexibility: LP and HX devices. The LP devices have ultra

low static and dynamic power consumption. HX devices are designed to provide high performance. Both the LP

and the HX devices operate at 1.2V VCC.

iCE40 devices feature iCEGate and PLL low power mode to allow users to meet the static and dynamic power

requirements of their applications. While these features are available in both device types, these features are

mainly intended for use with iCE40 LP devices to manage power consumption.

Table 2-9. iCE40 Power Saving Features Description

Device Subsystem Feature Description

PLL When LATCHINPUTVALUE is enabled, forces the PLL into low-power mode; PLL output held static

at last input clock value.

iCEGate

To save power, the optional iCEgate latch can selectively freeze the state of individual, non-regis-

tered inputs within an I/O bank. Registered inputs are effectively frozen by their associated clock or

clock-enable control.
