The board module EVALXCS-PQ208 is an ideal tool to test complex digital
circuits during the early states of their development. The various configuration
options of the Xilinx FPGAs allow the easy implementation of applications.
The hardware configuration may be loaded via XChecker or SPROM. Almost
all I/O pins of the FPGA are routed to header connectors, a total of 150
signals. These signals may be used as inputs or outputs.
Xilinx FPGA Spartan XCS40/30/20 (5V) or XCS40XL/30XL/20XL (3.3V) in PQ-208
- Quarz oscillator in socket, up to 80MHz (DIL-8 or DIL-14 package possible)
- Connector for XChecker connection
- SPROM socket (DIL-8) for FPGA Master Serial Mode
- Two pole connector for +5V/+3.3V power supply
- 4 layer PCB
- Clock signals may be equipped with termination resistors
- Stand alone usage of the board module possible
- The module has a standard size of 15cm x 10cm and a digital
interface compatible with future products:
3x50 pole header connectors (2.54mm grid spacing) on each long side of
The header connectors stand of from the top side of the PCB, socket connectors
from the bottom side.
- Modules may be stacked in form of a tower

Several board modules may be stacked to form a tower which enables one
to realise circuits whose demand of gates is beyond the scope of a single
FPGA. By using an external daisy chain connection, the whole stack can
be configured at once with a single download operation.
Seven clock sources can be used whereas one clock source is either the
internal quarz oscillator or an external clock source. The quarz oscillator
is inserted in a socket and can therefore be exchanged easily. Both DIL-8
and DIL-14 packages can be used. All clock signals may be terminated (parallel
termination to ground) with termination resistors. These resistors can
be soldered to the bottom side of the PCB.
A four position DIP switch is available for user defined purposes. There
is also a push button whose primary intent is to serve as a reset button.
Since this button is connected to a general I/O pin it may be used for
An LED row with eight SIDELEDs is able to display status messages, error
