F71863
1. General Description
The F71863 is the featured IO chip for PC system. Equipped with one IEEE 1284
Parallel Port, two UART Ports, Hardware Keyboard Controller, Serial Peripheral Interface
(SPI), SIR and one FDC. The F71863 integrated with hardware monitor, 9 sets of voltage
sensor, 3 sets of creative auto-controlling fans and 3 temperature sensor pins for the
accurate dual current type temp. measurement for CPU thermal diode or external
transistors 2N3906. Others, the F71863 supports newest AMDSI and Intel PECI interfaces
for temperature sensing. For AMD platform, the F71883 procides the power sequence
controller function.
The F71863 provides flexible features for multi-directional application. For instance,
supports 4-In and 4-Out pins CPU VID controlling with offset implement., provides 25 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/Stage Auto
Mode/Linear Auto Mode for users’ selection.
The F71863 also integrated SPI interface. The SPI interface is for BIOS usage
including bridge function and back up function. User can implement BIOS data in second
flash to boot system when primary BIOS error. These features as above description will help
you more and improve product value. Finally, the F71863 is powered by 3.3V voltage, with
the LPC interface in the green package of 128-PQFP.
