PC87373 General Description
The National Semiconductor® 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 includes legacy SuperI/O functions, system glue functions, fan monitoring and control, commonly used functions such as GPIO, and ACPI-compliant Power Management support.
The PC87373 integrates miscellaneous analog and digital system glue functions to reduce the number of discrete components required. The host communicates with the functions integrated in the PC87373 device through an LPC Bus Interface.
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.
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.
