Overview
The X-Board is a complete circuit development
platform for Xilinx’s CoolRunner
TM
-II CPLD. It
provides all essential support circuits for the
CoolRunner-II, so users can focus on creating
and downloading new designs. An on-board
USB2 port supplies power to the board and
provides a data port for CPLD configuration as
well as user data transfers.
More than 75 CPLD signals are routed to
expansion connectors so designs can easily be
extended. Thirty-two signals are routed to 6-pin
connectors that can accommodate Digilent’s
Pmod I/O modules – Pmods are small, low-cost
accessory boards offering circuits like A/D and
D/A converters, various I/O ports, and high-
current outputs for motor drivers, etc.
X-Board features include:
A 256 macrocell CoolRunner-II CPLD
in a TQ-144 package
An on-board USB2 port for JTAG
programming and user-data transfers
An on-board 16-bit A/D converter to
measure real-time CPLD current during
board operation (data is sent to the PC
for display via the USB cable)
An user-settable silicon oscillator
(1000/100/10 KHz), plus pads for a
second crystal oscillator
12 LEDs and two pushbuttons for
on-board I/O
Functional Description
The X-Board provides an inexpensive, robust, and easy-to-use platform that anyone can use to gain
experience with the latest CPLD devices and modern design methods. It is centered on the
CoolRunner-II CPLD, and it contains all needed support circuits so designs can get up and running
quickly. The X-Board is an ideal introductory platform for experimenting with new designs or learning
about CPLDs and CAD tools. The large collection of expansion connectors allow designs to grow
beyond the X-Board, either with user-designed boards or breadboards and/or peripheral module
(Pmod) boards offered by Digilent.
