FM3570 Rev. A
The Fairchild FM3570 replaces the CPU motherboard’s configu-
ration switches with an electronic implementation consisting of a
4/5-bit multiplexed, 1-bit latched port, standard 2-wire bus inter-
face, and non-volatile latches.
The FM3570 multiplexes the I-port input signals with two internal
non-volatile registers that can be loaded through the serial port.
The multiplexer is selected via the serial port and defaults to the
I-port upon power-up. 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
levels.

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, write data to the internal non-volatile
registers and select whether the I-port or one of the internal non-
volatile registers is output to the Y-port. The FM3570 is fabricated
with advanced CMOS technology to achieve high density and low
power operation.
