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 and to write data to the internal non-  
volatileregisters. TheFM3565isfabricatedwithadvancedCMOS  
technology to achieve high density and low power operation.  
General Description  
The Fairchild FM3565 replaces the PC motherboard’s CPU  
configurationswitcheswithanelectronicimplementation,consist-  
ing of a 5-bit multiplexed port, standard 2-wire bus interface, and  
non-volatile latches with external hardware control.  
Features  
I Extended Operating Voltage Range 3.0V-5.5V  
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  
opendrainoutputsandtoeliminatetheneedforexternalresistors.  
The device has open-drain outputs for easy interface to devices  
with different VDD Levels.  
I IIC Compatible Slave Interface.
