Chapter 13:

Expansion Connectors and Boards

Each port offers some ability to program the FPGA on the Spartan-3 Starter Kit Board. For

example, port A1 provides additional logic to drive the FPGA and Platform Flash JTAG

chain. Similarly, ports A2 and B1 provide connections for Master or Slave Serial mode

configuration. Finally, port B1 also offers Master or Slave Parallel configuration mode.

Each 40-pin expansion header, shown in Figure 13-2, uses 0.1-inch (100 mil) DIP spacing.

Pin 1 on each connector is always GND. Similarly, pin 2 is always the +5V DC output from

the switching power supply. Pin 3 is always the output from the +3.3V DC regulator.

The pinout information for each connector appears below. The tables include the

connections between the FPGA and the expansion connectors plus the signal names used

in the detailed schematic in Figure A-1.
