LPC Interface

The LPC (Low Pin Count) bus is provided as a replacement for the increasingly less often used ISA bus. The LPC bus is used on PC-style personal computers to connect low-bandwidth devices to the CPU, such as the boot ROM, "legacy" I/O devices (supported by a Super I/O chip), and audio controllers. The "legacy" I/O devices usually include serial and parallel ports, keyboard, mouse, and a floppy disk controller. Due to the software compatibility of the LPC bus to the ISA bus, I/O devices such as additional serial ports can be easily implemented on an application specific baseboard using the LPC bus. There are also many devices available for the LPC bus.

Extended System Management

The Extended System Management interface, implemented by the Super I/O chip (W83627HG), provide additional signals and functions to further improve system management. One of these signals is an output signal called FAN_PMOUT that allows system fan control using a PWM (Pulse Width Modulation) Output. Additionally there is an input signal called FAN_TACHOIN that provides the ability to monitor the system fan's RPMs (revolutions per minute).
