FM3565 Rev. A.1
The Fairchild FM3565 replaces the PC motherboard’s CPU
configuration switches with an electronic implementation, consist-
ing of a 5-bit multiplexed port, standard 2-wire bus interface, and
non-volatile latches with external hardware control.
The FM3565 multiplexes the I-port input signals with two internal
non-volatile registers that can be loaded through the serial port.
The multiplexer output is under hardware control, and is deter-
mined by the inputs OVRD, MUXSEL, and A/B. Pull-up resistors
are provided on the input port to accommodate connections to
open drain outputs and to eliminate the need for external resistors.
The device has open-drain outputs for easy interface to devices
with different V

The serial port is an IIC compatible slave-only interface and
supports both 100kbit and 400kbit modes of operation. The port
is used to read the I-Port and to write data to the internal non-
volatile registers. The FM3565 is fabricated with advanced CMOS
technology to achieve high density and low power operation.
