Digilab XC95 Reference Manual
Revision: May 7, 2002
Overview
The Digilab XC95 (DXC95) development
board featuring the Xilinx 95108 CPLD
provides an inexpensive and expandable
platform on which to design and implement
basic digital circuits. The board can also be
used to program other Digilent peripheral
boards (such as the DIO2 board) that contain
CPLD devices. DXC95 board features include:
• A Xilinx 95108 CPLD with 108
macrocells;
• An on-board 1.5A, 5VDC power
regulator;
• A socketed 1.842MHz oscillator;
• A JTAG-based programming port using a
standard parallel cable;
• A status LED and pushbutton for basic
I/O;
• Two 100-mil spaced, right-angle DIP
socket 40-pin expansion connectors.
The DXC95 board has been designed
specifically to work with the Xilinx ISE CAD
tools, including the free WebPack tools
available from the Xilinx website. Like other in
the Digilab family, the DXC95 board has been
partitioned so that only the hardware required

Several peripheral boards that mate with the
expansion connectors are available, such as the
DIO1 board that provides several basic I/O
devices (see www.digilentinc.com for more
information). The low-cost, standard expansion
connectors allow new peripheral boards,
including wire-wrap or manually soldered
boards, to be quickly designed and used. The
DXC95 board ships with a power supply and
programming cable, so designs can be
implemented immediately without the need for
any additional hardware.
