F75122RG 数据手册

1. General Description

The F75122 is the dynamic voltage ID controller chip to provide the advanced CPU voltage

programming when over clocking. F75122 supports the dynamic VID spec. for new generation

Intel Prescott CPU and also compatible to VRM10.0/VRM9.X spec.. Auto sensing CPU

replacement and setting watch dog timer for OS idling protection. Besides of VID controlling

function, F75122 also supports pure 8 GPIO pins. Level or pulse modes can be programmed

by registers. With 2 sets of watchdog timer, F75122 provides more flexible control for PC

system, and there are four kinds of pulse width of the time out alert output pin can be selected.

2. Features

Supporting new generation Intel dynamic Processor VID input /output

Supporting Intel Prescott CPU low level input (V_IH> 0.9V, V_IL<0.8V)

Compatible VRM 9.X and VRM10.0

Auto detecting the CPU replacement

Pure 8 GPIO pins

Two sets of Watch dog timer to protect system from hanging when over-clocking

SMbus interface

Package in 28-SSOP (150mil)
