1 / 168 page  www.national.com © 1999 National Semiconductor Corporation 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® Interface (ACB), System Wake-Up Control (SWC), Interrupt Serializer for Parallel IRQs and an enhanced WATCHDOG ™ timer. Outstanding Features q Bus interface, based on Intel’s LPC Interface Specifi- cation Revision 1.0, September 29th, 1997 q Protection features, including I/O access lock, GPIO lock and pin configuration lock q 45 GPIO Ports (37 standard, including 23 with Assert IRQ/SMI/PWUREQs interrupts; 8 VSB-powered) q Fan Speed Control and Monitor for two fans q Interrupt Serializer (11 Parallel IRQs to Serial IRQ) q Serial IRQ support (15 options) q ACCESS.bus Interface, compatible with SMbus physi- cal layer q Blinking LEDs q 128-pin PQFP Package Block Diagram System Wake-Up Serial Port 2 IEEE 1284 Wake-Up Parallel Port Ports Keyboard & Mouse I/F SCL ACCESS.bus Floppy Disk Controller Floppy Drive Interface Keyboard & Serial Infrared Interface Interface Control Events Bus Interface LPC Interface I/O 2 Control WATCHDOG Timer WDO PWUREQ Serial Port 1 Serial Interface Outputs Fan Speed Control & Monitor Interface Mouse Controller with IR GPIO Ports 2 Monitor Inputs SDA Serial IRQ Parallel IRQs Interrupt Parallel Port Interface SMI Ports Serializer VDD VBAT VSB PRELIMINARY January 10, 1999 PC87360 128-Pin LPC SuperI/O with Protection and Extensive GPIO Support ACCESS.bus® is a registered trademark of Digital Equipment Corporation.
