Product Summary
The F71883FG is a Super Hardware Monitor .The F71883FG is the featured IO chip for PC system. Equipped with one IEEE 1284 parallel port, two UART ports, KBC, Serial Peripheral Interface (SPI), 80-Port, SIR and one FDC. The F71883FG integrated with hardware monitor, 9 sets of voltage sensor, 4 sets of creative auto-controlling fans and 4 temperature sensor pins for the accurate dual current type temp. measurement for CPU thermal diode or external transistors 2N3906. The F71883FG provides flexible features for multi-directional application. For instance, supports 6/12 pins CPU VID controlling for VRM9.0/10.0/11 and CPU VID OTF (On The Fly), provides 32 GPIO pins (multi-pin), IRQ sharing function also designed in UART feature for particular usage and accurate current mode H/W monitor will be worth in measurement of temperature, provides 3 modes fan speed control mechanism included Manual Mode/Speed Mode/Temperature Mode for users’ selection Additionally, provides easy voltage sensor input (VSI) function for sensing Vcore voltage, then output (VSO) the offset voltage for over/under voltage change use.
