Introduction; Features; Figure 2.1. Top Side Of The Ice40Hx-8K Evaluation Board - Lattice Semiconductor iCE40HX-8K User Manual

1. Introduction

This document provides technical information and instructions for using the iCE40™HX-8K Breakout Board. This kit is
based on the Lattice iCE40-HX8K-CT256 high performance FPGA device. Two source codes, one written in Verilog and
the other in VHDL, are available to download for the iCE40HX-8K Breakout Board. Both codes are functionally the same.
The contents of this user guide include demo operation, top-level functional descriptions of the various portions of the
evaluation board, descriptions of the on-board connectors, switches, a complete set of schematics, and the bill of
materials for the iCE40HX-8K Evaluation Board.

2. Features

The iCE40HX-8K Breakout Board includes:

iCE40HX-8K Evaluation Board – The iCE40HX-8K Evaluation Board features the following onboard capabilities:

iCE40HX-8K CT256 device

Eight user-accessible LEDs

SPI Flash for programming configuration

40 pin 0.1" header for user connectivity

0.1" holes for user connectivity

FTDI 2232H for USB interface

12 MHz oscillator

Jumpers to select programming the SPI flash or iCE40HX-8K

Pre-loaded Demo – The kit comes with a default design that flashes the LEDs on and off.

USB connector Cable – A mini B USB cable for programming the SRAM fabric of the iCE40HX-8K or the onboard SPI
flash. The USB cable also powers the iCE40HX-8K evaluation board.
