FM3570 Datasheet (Fairchild Semiconductor) - CPU CONFIGURATION CONTROLLER

FM3570, CPU CONFIGURATION CONTROLLER

The Fairchild FM3570 replaces the CPU motherboard’s configuration switches with an electronic implementation consisting of a 4/5-bit multiplexed, 1-bit latched port, standard 2-wire bus interface, and non-volatile latches.

The FM3570 multiplexes the I-port input signals with two internal non-volatil
