PC87365 128-Pin LPC SuperI/O with System Hardware Monitoring PRELIMINARY November 2000 Revision 2.01 PC87365 128-Pin LPC SuperI/O with System Hardware Monitoring General Description The PC87365, a member of National Semiconductor’s 128pin LPC SuperI/O family, features National’s new System Hardware Monitoring capability. The PC87365 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 consumption and maximum operating efficiency within the system environment. It integrates National’s Voltage Level Monitor (VLM) which monitors system voltages using 8-bit Analog to Digital (A/D) conversion, seven analog input channels and VREF input, and National’s diode input Temperature Sensor for full, PC system thermal control. The PC87365 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), ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) support for 40 ports, Interrupt Serializer for Parallel IRQs, an enhanced WATCHDOG Timer (WDT), a full IEEE 1284 Parallel Port and two enhanced Serial Ports (UARTs), one with Infrared (IR) support. Outstanding Features q System Hardware Monitoring including: — Diode-based Temperature Sensor (TMS) — Voltage Level Monitor ...
