iCE40HX-8K Breakout Board Users Guide November 2013 EB85 01.0iCE40HX-8K Breakout Board Introduction Thank you for choosing the Lattice iCE40HX-8K Breakout Board. This document provides technical information and instructions for using the iCE40HX-8K Breakout Board. This kit is based on the Lattice iCE40-HX8K-CT256 high performance FPGA device. Two source codes, one written in Ver- ilog and the other in VHDL, are available to download for the iCE40HX-8K Breakout Board. Both codes are func- tionally the same. The contents of this users 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. Features The iCE40HX-8K Breakout Board includes: iCE40HX-8K Evaluation Board The iCE40HX-8K Evaluation Board features the following on board capabili- ties: iCE40HX-8K CT256 device 8 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 12Mhz 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 on- board SPI flash. The USB cable also powers the iCE40HX-8K evaluation board. Figure 1 shows the top side of the iCE40HX-8K Evaluation Board indicating the specific features that are designed on the board. 2
