CPU CONFIGURATION CONTROLLER  
Register/Multiplexer for Microprocessor VID  
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.  
General Description  
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 VDD  
levels.  
Features  
I Extended Operating Voltage Range 3.0V-5.5V  
I IIC Compatible Slave Interface.  
I ESD performance: Human body model > 2000V  
I Choice of 2.5V Outputs or Open-Drain Outputs
