F81865
1. General Description
The F81865 is the featured IO chip for Industrial PC system. Equipped with one IEEE
1284 parallel port, 6 UART ports with 9-bit protocol, KBC, Serial Peripheral Interface (SPI),
SIR and one FDC. The F81865 integrated with hardware monitor, 7 sets of voltage sensor, 2
sets of creative auto-controlling fans and 2 temperature sensor pins for the accurate dual
current type temperature measurement for CPU thermal diode or external transistors
2N3906.
The F81865 provides flexible features for multi-directional application. For instance,
supports 53 GPIO pins, IRQ sharing function designed in UART feature for particular usage
and accurate current mode H/W monitor will be worth in measurement of temperature, the
F81865 also integrated SPI interface. The SPI interface is for BIOS usage including bridge
function. Others, the F81865 supports newest Intel PECI interfaces for new generational
CPU temperature use. Furthermore, F81865 provides independent RTC function.
These features as above description will help you more and improve product value.
Finally, the F81865 is powered by 3.3V voltage, with the LPC interface in the package of
128-PQFP.
