Overview

Digilent’s Basys circuit board is an integrated

circuit development platform based on a Xilinx

Spartan 3E Field Programmable Gate Array

(FPGA). The Basys board provides a low-

cost, introductory development platform for

engineers to try new designs or learn about

FPGAs and modern CAD tools. Basys

features include:

• 100,000 gate Xilinx Spartan 3E FPGA;

• JTAG programming port;

• XCF02S Xilinx Platform Flash ROM to

store FPGA configurations;

• Large collection of I/O devices including

eight LEDs, four-digit seven-segment

display, four pushbuttons, and eight slide

switches;

• PS/2 and VGA ports;

• User-selectable oscillator

(25/50/100MHz), plus a socket for a

second oscillator;

• Four 6-pin header ports for user I/O and

peripheral module connection;

• ESD and short-circuit protection on all I/O

signals.

Functional Description

The Basys board provides an inexpensive,

robust, and easy-to-use platform that anyone

can use to gain experience with FPGA devices

and modern design methods. It is centered on

the Spartan 3E FPGA, and it contains all needed support circuits so designs can get up and running

quickly. The large collection of on-board I/O devices allow many designs to be completed without the

need for any other hardware, making the Basys an ideal introductory platform for experimenting with

new designs or learning about FPGAs and CAD tools. The four standard 6-pin expansion connectors

allow designs to grow beyond the Basys board, either with user-designed boards or breadboards

and/or peripheral module (Pmod) boards offered by Digilent. (Pmods are inexpensive analog and

digital I/O modules that offer A/D conversion, D/A conversion, motor drive, sensor input, and a host of

other features). Signals on each 6-pin expansion connector are protected against damage from ESD

and short-circuit connections, ensuring a long operating life in any environment. The Basys board

works seamlessly with all versions of the Xilinx ISE tools, including the free WebPack tools. It ships

with a power supply and programming cable, so designs can be implemented immediately without the

need for any additional hardware.
