F71869E
General Description

The F71869E which is the featured IO chip for PC system is equipped with one IEEE 1284 Parallel Port,two UARTPorts, Hardware Keyboard Controller, SIR and one FDC. The F71869E integrates 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 temperature measurement for CPU thermal diode or external transistors 2N3906. Others, the F71869E supports newest AMD TSI and Intel PECI 3.0 interfaces and INTEL Ibex PEAK SMBus for temperature sensing and provides the power sequence controller function for AMD platform

The F71869E provides flexible features for multi-directional application. For instance, the F71869E provides 45 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.

A power saving function which is in order to save the current consumption when the system is in the soft off state is also integrated a power saving function. The power saving function supports that system boot-on not only by pressing the power button but also by the wake-up event. When the system enters the S4/S5 state, F71869E can cut off the VSB power rail which suppliespower source to the devices likethe LAN chip, the chipset, the SIO, the audio codec, DRAM, and etc. The PC system can be simulated to G3-like state when system enters the S4/S5 states. At the G3-like state, the F71869E consumes the 5VSB power rail only. The integrated two control pins are utilized to turn on or off VSB power rail in the G3-like status. The turned on VSB rail is supplied to a wake up device to fulfill a low power consumption system which supports a wakeup function.

These features as above description will help you more and improve product value. Finally, the F71869E is powered by 3.3V voltage, with the LPC interface in the green package of 128-LQFP (14*14).
