• Manufacturer Part Number: f75334
• Description: Performance Controller
• Manufacturer: Feature Integration Technology Inc.

1. General Description
2. Feature List
Monitor, PWM Loading Gauge, VID controller and GPIO functions inside. Part of the Hardware Monitor
is for system protection including 6 channels voltage monitor, 4 sets dual current sources temperature
sensor, 3 sets fan speed sensor and controller. Besides, provides Intel new generational temperature
interfaces PECI/SST for temperature reading and also supports AMDSI interface for AMD series CPU
temperature reading. PWM Loading Gauge is sensing the PWM signal change of duty cycle to react
related functions for over/under-clocking application. VID controller is the dynamic voltage ID controller
chip to provide the advanced CPU voltage programming when over/under clocking. The dynamic VID
spec. is for new generation Intel/AMD CPU and also compatible to VRM9.0/VRM10.0/VRM10.X
/VRM11.0 spec.. Additionally, the F75334DG provides easy voltage sensor input/output (VSI/VSO)
function to sense Vcore voltage, then output the offset voltage for over/under voltage change use.
Otherwise, F75334DG provides 21 GPIO pins for flexible application.
and dynamic voltage ID control. The F75334DG can easy save total cost and improve system
performance.
over/under-clocking being easy function. The F75334DG support 2 wire I2C interface, packaged in
48-pin LQFP green package and powered by 3.3V.
