Revision 1.2  
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 VSB3, 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  
ꢀ VSB3-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
