This page lists the pinouts of the expansion connectors on the Spartan 3 starter board. It is intended as a quick reference to show which pins are available to use on all of the connectors interchangably. It does not replace the Xilinx user guide at http://www.xilinx.com/support/documentation/boards_and_kits/ug130.pdf

A1 Connector

The pins marked in orange are connected to the SRAM IO pins. To use them, the SRAM chip enable lines should be driven high. These are pins P7 and N5, which are not on the A1 connector.
