128-Pin LPC SuperI/O with System Hardware Monitoring, MIDI and Game Ports
PC87366 128-Pin LPC SuperI/O with System Hardware Monitoring and MIDI and Game Ports
General DescriptionThePC87366,a memberofNational Semiconductor’s128-pin
LPC SuperI/O family, combines National’s System Hardware
Monitoringcapability with aMusical InstrumentDigital Interface
(MIDI) Port and game port inputsforupto two joysticks. The
PC87366is PC99and ACPI compliant and offersa single-chip
solution to the most commonly used PC I/O peripherals.
System Hardware Monitoring provides minimum power con-
sumption and maximum operating efficiency withinthe system
environment.It integratesNational’sdiode-basedor thermistor-
based Temperature Sensor (TMS)withNational’s VoltageLev- Monitor (VLM) for full PC system thermal control. The
PC87366 monitors system voltages using 8-bit Analogto Dig-
ital (A/D) conversion with seven analog input channels andfour
internal measuring points.
The PC87366 also incorporates: Fan Speed Control and
Monitor (FSCM)for three fans, extended wake-up support
for awiderangeof wake-upevents, systemdesignprotection
features,a Floppy Disk Controller (FDC),a Keyboard and
Mouse Controller (KBC), ACCESS.bus® Interface (ACB),
System Wake-Up Control (SWC), General-Purpose In-
put/Output (GPIO) support for 40 ports, an enhanced
WATCHDOG Timer (WDT),afull IEEE 1284 Parallel Port
and two enhanced Serial Ports (UARTs), one with Infrared
(IR) support.
Outstanding Features System Hardware Monitoring including:
Diode-basedor thermistor-based Temperature Sen-
sor (TMS)
Voltage Level Monitor (VLM) with VID inputs MIDI Interface compatible with MPU-401 UART mode Game port inputsforupto two joysticks Extended Wake-Up support, including legacy/ACPI
power button support, direct power supply controlin
