W83637HF
The W83637HF provides a set of flexible I/O control functions to the system designer through a set of
General Purpose I/O ports. These GPIO ports may serve as simple I/O or may be individually
configured to provide a predefined alternate function.
The W83637HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide.
Moreover, W83637HF is made to meet the specification of PC2001's requirement in the power
management: ACPI 1.0/1.0b/2.0 and DPM (Device Power Management).
The W83637HF contains a game port and a MIDI port. The game port is designed to support 2
joysticks and can be applied to all standard PC game control devices. They are very important for an
entertainment or consumer computer.
The W83637HF supports hardware status monitoring for personal computers. It can be used to monitor
several critical hardware parameters of the system, including power supply voltages, fan speeds, and
temperatures, which are very important for a high-end computer system to work stably and properly.
Moreover, W83637HF support the Smart Fan control system, including the “Thermal Cruise^TM” and
