Faraday Electronics FE3000A CPU Control Logic

The FE3000A is an 84-pin chip that provides the control and timing signals for a IBM PC/AT-compatible mainboard. It is intended to be used together with the FE3010 AT peripheral controller, the FE3020 AT addresss buffer, and the FE3030 AT data buffer. Together these four chips form the FE3400B chipset.

The FE3000A is used in the GRiDcase 1520 mainboard (revision 2).

The original datasheet is available for download.
