I/O Line Connections
There are 16 I/O lines that connect the XC3020A and XC4003E
FPGAs.Theseareshowninthefollowingtable.
Optional Crystal Oscillator (Y1)
You can add a standard 4-pin crystal oscillator to the FPGA Demon-
stration Board. The oscillator output drives the XC3020A XTL2 input
at pin 43 and the XC4003E PGCK1 input at pin 13.
Prototype Area
The Prototype area is a 0.1-inch grid of holes where you can add
additional circuitry to the demonstration board. A +5 V bus (compo-
