The F71889E which is the featured IO chip for new generational PC system is equipped with one IEEE 1284 parallel port, two UART ports, KBC, 80-Port, SIR, and VID controller. The F71889E integrated with hardware monitor, 9 sets of voltage sensor, 3 sets of creative auto-controlling fans and 3 temperature sensor pins for the
( F71889ED ) accurate dual current type temp.measurement for CPU thermal ( F71889ED ) diode or external transistors 2N3906
The F71889E provides flexible features for multi-directional application. ( F71889ED ) For instance, supports Bus Interface pins, provides 54 GPIO pins (multi-pin), IRQ sharing ( F71889ED ) function also designed in UART feature for particular usage and accurate current mode H/W monitor will be worth in ( F71889ED ) measurement of temperature, provides 3 modes fan speed control mechanism included Manual Mode/Speed Mode/Temperature Mode ( F71889ED ) for users’ selection
In order to save the current consumption when the ( F71889ED ) system is in the soft off state which is so called power saving function. The power saving function supports ( F71889ED ) the system boot-on not only by pressing the power button but also by the wake-up event. When the system enters the S3/S4/S5 state, F71889E can cut off ( F71889ED ) the VSB power rail which supplies power source to the devices like the LAN chip, the ( F71889ED ) chipset, the SIO, the audio codec, DRAM, and etc. The PC system can be simulated to G3-like state when system ( F71889ED ) enters S3/S4/S5 states. At the G3-like state, the F71889E consumes 5VSB power rail only. ( F71889ED ) 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 ( F71889ED ) device to fulfill a low power consumption system which supports a wake up function.


Finally, the F71889ED is powered by 3.3V voltage, with the LPC interface in the package of 128-LQFP green package
