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.
