PC87366 Datasheet | National Semiconductor

Description The PC87366, a member of National Semiconductor’s 128-pin LPC Super I/O family, bines 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 pliant, and offers a singlechip solution to the most monly used PC I/O peripherals. System Hardware Monitoring provides minimum power consumption and maximum operating efficiency within the system environment. It integrates National’s diode-based or thermistorbased Temperature Sensor (TMS) with National’s Voltage Level Monitor (VLM) for full, PC system thermal control. The PC87366 monitors system voltages using 8-bit Analog to Digital (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) support, ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) support 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 Sensor (TMS) - Voltage Level Monitor (VLM) with VID inputs MIDI interface patible with MPU-401 UART mode Game port inputs for up to two joysticks 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 Fan Speed Control and Monitor for three fans Serial IRQ support (15 options) Interrupt Serializer (11 Parallel IRQs to Serial IRQ) Bus interface, based...
