1 / 180 page  www.national.com PRELIMINARY January 10, 1999 PC87364 128-Pin LPC SuperI/O with Extended Wake-Up and Protection Support General Description The PC87364, a member of National Semiconductor’s 128- pin LPC SuperI/O family, introduces wake-up support for a wide range of wake-up events, and new hardware and sof- ware features to protect the system design. The PC87364 provides support for 51 GPIO ports, many with Assert IRQ/SMI/PWUREQ capability. It is PC99 and ACPI compli- ant, and offers a single-chip solution to the most commonly used PC I/O peripherals. The PC87364 also incorporates: Fan Speed Control and Monitor (FSCM) for three 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), General-Purpose Input/Output (GPIO) support for 51 ports, Interrupt Serializer for Parallel IRQs and an enhanced WATCHDOG ™ timer. Outstanding Features • Extended Wake-Up support, including legacy/ACPI power button support, direct power supply control in response to wake-up events, power-fail recovery • Protection features, including I/O access lock, chassis hood lock/unlock, chassis intrusion detection, GPIO pin attribute lock and pin configuration lock • Fan Speed Control and Monitor for three fans • Serial IRQ support (15 options) • Interrupt Serializer (11 Parallel IRQs to Serial IRQ) • Bus interface, based on Intel’s LPC Interface Specifi- cation Revision 1.0, September 29th, 1997 • ACCESS.bus Interface, SMBus physical layer compatible q 51 GPIO Ports (39 standard, including 23 with Assert IRQ/SMI/PWUREQs interrupts; 12 VSB-powered) • Blinking LEDs • 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 3 Control WATCHDOG Timer WDO PWUREQ Serial Port 1 Serial Interface Outputs Fan Speed Control & Monitor Interface Mouse Controller with IR GPIO Ports 3 Monitor Inputs SDA Serial IRQ Parallel IRQs Interrupt Parallel Port Interface SMI Ports Serializer Power Control VDD VBAT VSB © 1999 National Semiconductor Corporation ACCESS.bus® is a registered trademark of Digital Equipment Corporation.
