F75121 数据手册

1. General Description

The F75121 is the dynamic voltage ID controller chip to provide the advanced CPU voltage

programming when over clocking. F75121 supports the dynamic VID spec. for new generation

Intel 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, F75121

also supports pure 8 GPIO pins. Level or pulse modes can be programmed by registers. With

2 sets of watchdog timer, F75121 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

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)
