PC87363 128-Pin LPC SuperI/O with MIDI and Game Ports, Extended Wake-Up and Protection PRELIMINARY January 10, 1999 PC87363 128-Pin LPC SuperI/O with MIDI and Game Ports, Extended Wake-Up and Protection General Description The PC87363, a member of National Semiconductor’s 128pin LPC SuperI/O family, introduces a Musical Instrument Digital Interface (MIDI) Port and Game Port inputs for up to two game devices. It also offers wake-up support for a wide range of wake-up events, and new hardware and software features to protect the system design. Like all members of this family, it is PC99 and ACPI compliant, and offers a singlechip solution to the most commonly used PC I/O peripherals. The PC87363 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, ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) support for a total of 49 ports and an enhanced WATCHDOG™ timer. Outstanding Features q q q MIDI Port compatible with MPU-401 UART mode Game Port inputs for up to two game devices 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 chassis intrusion detection, GPIO lock and pin configuration lock Serial IRQ support (15 options) Bus interface, based on Intel’s LPC Interface Specification Revision 1.0, September 29th, 1997 Fan Speed Control and Monitor for two fans ACCESS.bus Interface, SMBus physical layer compatible 49 GPIO Ports (37 standard, including 23 with Assert IRQ/SMI/PWUREQs interrupts; 12 VSB-powered) Blinking LEDs 128-pin PQFP Package q q q q q q q q Block Diagram Serial Interface Floppy Drive Interface Parallel Port LPC Serial Interface Interface IRQ SMI Game Device Interface Serial Infrared Interface Interface I/O Ports Serial Port 1 Serial Port 2 with IR GPIO Ports Floppy Disk Controller IEEE 1284 Parallel Port Bus Interface Game Port VDD VBAT VSB System Wake-Up Control ACCESS.bus Interface WATCHDOG Timer Fan Speed Control & Monitor Keyboard & Mouse Controller MIDI Port Power Wake-Up PWUREQ SCL SDA Control Events WDO 2 Control 2 Monitor Keyboard & Ports Mouse I/F Outputs Inputs MIDI Interface ACCESS.bus® is a registered trademark of Digital Equipment Corporation.
