Expansion connectors
The two expansion connectors labeled E and F on the D2XL
board use 100 mil spaced DIP headers. Both connectors
have GND routed to pin 1, VU routed to pin 2, and 3.3V
routed to pin 3. Pins 4-40 for both connectors route directly to
individual FPGA pins. The connectors are separated by 400
mils, so any D2-family peripheral board can be placed used
with the D2XL board.
The TQ144 package used on the D2XL board has 77 signal
pins available to the user (the remaining I/O signals are
routed to the parallel connector and other on board devices).
Of these, 37 are routed to the E connector, 37 to the F
connector, and 3 are left unconnected. Data rates of up to
100MHz are attainable across the E and F connectors.
