XS40
BOARD
The project targets the XESS XS40-005XL V.1.2 FPGA
board in Photo 1, which includes a Xilinx XC4005XL,
12-MHz oscillator (see Figure 1), 32-KB SRAM, 8031
MCU, 7-segment LED, voltage regulators, and parallel
port and VGA port connectors. It’s simple, inexpensive,
and is featured in The Practical Xilinx Designer
Lab Book included with Xilinx Student Edition.

depicts the subset of the XS40 needed for
our project.
The 8031 (not shown) is held in reset. |
I
chose this board because it is well supported with
documentation and tools, and because it can be used
for both the XSE exercises and this project.
