F76761
General Description

The F76761 which is the featured IO chip with μC based on 8-bit 8032 core which is equipped with SPI Interface, KBC, IEEE 1284 parallel port, 2 UART ports, and 80-Port (multi with COM2). The F76761 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.

The F76761 provides 67 GPIO pins for flexible application and IRQ sharing function also designed in UART feature for particular usage and accurate current mode. F76761 provides 4 fans and 4 fan control modes with 4-limit and 5-stage fan speed control mechanism included Manual Mode, Stage Auto Mode and Linear Auto Mode for users’ selection. When system is over limited temperature, the alert signals act like beep or shutdown. Others, the F76761 supports newest AMD new interface TSI and Intel PECI 3.0 interfaces and INTEL SMBus for temperature reading. These features will help you more and improve product value.

Fintek power saving function contains Intel Deep Sleep WellTM (DSW) and G3-Like of Super IO configurable feature, these enable the system to dissipate less power (Watt) in hibernation (S5) with no impact to run and sleep power modes. Fintek power saving function supports the system boot-on, not only by pressing the power button but also by the wake-up event.

At the G3-Like state, the control pin (ErP_CTRL) is 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 wake up function.

Finally, the F76761 is powered by 3.3V voltage, with the LPC interface in the package of 128-LQFP (14mm*14mm) green package.
