PC87366
128-Pin LPC SuperI/O with System Hardware Monitoring,
MIDI and Game Ports
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).
