General Description

The PC87360 is the first member of National Semiconduc-

tor’s 128-pin SuperI/O family to support the Low Pin Count

(LPC) interface. It provides features to protect the system

design, and supports 45 GPIO ports, many with Assert

IRQ/SMI/PWUREQ capability. The PC87360 is PC99 and

ACPI compliant, and offers a single-chip solution to the

most commonly used PC I/O peripherals.

The PC87360 also incorporates: Fan Speed Control and

Monitoring for two fans, a Floppy Disk Controller (FDC), a

Keyboard and Mouse Controller (KBC), a full IEEE 1284

Parallel Port, two enhanced Serial Ports (UARTs), one with

Infrared (IR) support, an ACCESS.bus

System Wake-Up Control (SWC), Interrupt Serializer for

Parallel IRQs and an enhanced WATCHDOG
