GENERAL DESCRIPTION

The National PC87373 Advanced I/O product is a member of the PC8737x SuperI/O family. All PC8737x devices are highly integrated and are pin and software compatible, thus providing drop-in interchangeability and enabling a variety of assembly options using only a single motherboard and BIOS. PC87373 integration allows for a smaller system board size and saves on total system cost. The PC87373 Legacy functions are: two serial ports, a fully compliant IEEE 1284 Parallel Port, a Floppy Disk Controller (FDC), a Keyboard/Mouse Controller (KBC), a Game Port and a MIDI Port. The Fan Speed Control and Monitor (FSCM) module allows the system to monitor and control three fans. Semiconductor® The PC87373 extended wake-up support complements the ACPI controller in the chipset. The System Wake-Up Control (SWC) module, powered by VSB3, supports a flexible wakeup mechanism. There are 13 General-Purpose Input/Output (GPIO) ports; these allow system control and wake-up on system events.
