PC87372

LPC SuperI/O with Glue Functions

The PC87372 extended wake-up support complements the

ACPI controller in the chipset. The System Wake-Up Control

(SWC) module, powered by V_SB3, supports a flexible wake-

up mechanism.

General Description

The National Semiconductor^®PC87372 Advanced I/O prod-

uct is a member of the PC8737x SuperI/O family. All

PC8737x devices are highly integrated and are pin and soft-

ware compatible, thus providing drop-in interchangeability

and enabling a variety of assembly options using only a sin-

gle motherboard and BIOS.

There are 13 General-Purpose Input/Output (GPIO) ports;

these allow system control and wake-up on system events.

Outstanding Features

PC87372 integration allows for a smaller system board size and

saves on total system cost.

■ Legacy modules: Parallel Port, Floppy Disk Controller

(FDC), Serial Port and a Keyboard and Mouse Control-

ler (KBC)

The PC87372 includes legacy SuperI/O functions, system

glue functions, fan monitoring and control, commonly used

functions such as GPIO, and ACPI-compliant Power Man-

agement support.

■ Glue functions to complement the South Bridge func-

tionality

The PC87372 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 PC87372 device through an LPC

Bus Interface.

■ Fan Speed monitoring of two fans

■ V_SB3-powered Power Management with 20 wake-up

sources

■ Controls three LED indicators

The PC87372 Legacy functions are: a serial port (UART), a

fully compliant IEEE 1284 Parallel Port, a Floppy Disk Con-

troller (FDC) and a Keyboard/Mouse Controller (KBC).

■ 13 GPIO ports with a variety of wake-up options

■ LPC interface, based on Intel’s LPC Interface Specifica-

tion Revision 1.0, September 29th, 1997

The Fan Speed Monitor (FSM) module allows the system to

monitor two fans.

■ PC01 Revision 1.0 and Advanced Configuration and Pow-

er Interface (ACPI) Specification Revision 2.0 compliant

■ 128-pin PQFP package
