1 / 240 page  www.national.com General Description The PC87366, a member of National Semiconductor’s 128-pin LPC SuperI/O family, combines National’s System Hardware Monitoring capability with a Musical Instrument Digital Interface (MIDI) Port and game port inputs for up to two joysticks. The PC87366 is PC99 and ACPI compliant, and offers a single- chip solution to the most commonly used PC I/O peripherals. System Hardware Monitoring provides minimum power con- sumption and maximum operating efficiency within the system environment. It integrates National’s diode-based or thermistor- based Temperature Sensor (TMS) with National’s Voltage Lev- el Monitor (VLM) for full, PC system thermal control. The PC87366 monitors system voltages using 8-bit Analog to Dig- ital (A/D) conversion with seven analog input channels and four internal measuring points. The PC87366 also incorporates: Fan Speed Control and Monitor (FSCM) for three fans, extended wake-up support for a wide range of wake-up events, system design protection features, 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) sup- port, ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) sup- port for 40 ports, Interrupt Serializer for Parallel IRQs and an enhanced WATCHDOG ™ timer (WDT). Outstanding Features q System Hardware Monitoring including: — Diode-based or thermistor-based Temperature Sen- sor (TMS) — Voltage Level Monitor (VLM) with VID inputs q MIDI interface compatible with MPU-401 UART mode q Game port inputs for up to two joysticks q Extended Wake-Up support, including legacy/ACPI power button support, direct power supply control in response to wake-up events, power-fail recovery q Protection features, including chassis intrusion detection, GPIO lock and pin configuration lock q Fan Speed Control and Monitor for three fans q Serial IRQ support (15 options) q Interrupt Serializer (11 Parallel IRQs to Serial IRQ) q Bus interface, based on Intel’s LPC Interface Specifi- cation Revision 1.0, September 29th, 1997 q ACCESS.bus interface, SMBus physical layer compatible q 40 GPIO Ports (29 standard, including 15 with Assert IRQ/SMI/PWUREQs interrupts; 11 VSB-powered) q Blinking LEDs q 128-pin PQFP Package Block Diagram System Wake-Up Serial Port 2 IEEE 1284 Parallel Port Ports Keyboard & Mouse I/F SCL ACCESS.bus Floppy Disk Controller Floppy Drive Interface Keyboard & Serial Infrared Interface Interface Control Bus Interface LPC Interface I/O 3 Control WATCHDOG Timer WDO Serial Port 1 Serial Interface Outputs Fan Speed Control & Monitor Interface Mouse Controller with IR GPIO Ports 3 Monitor Inputs SDA Serial IRQ Analog Inputs System Parallel Port Interface Diode Interface SMI Ports Hardware Monitoring VREF MIDI Interface MIDI & Game Ports Game Inputs Wake-Up Events PWUREQ Power Control VDD VBdAT VSB AV DD ACCESS.bus® is a registered trademark of Digital Equipment Corporation.
