General Description
National Semiconductor’s PC8739x family of LPC SuperI/O
devices is targeted for a wide range of portable applications.
PC99 and ACPI compliant, the PC8739x family features
an X-Bus Extension for read and write operations over the
X-Bus, a full IEEE 1284 Parallel Port with a Parallel Port Mul-
tiplexer (PPM) for external Floppy Disk Drive (FDD) support,
a Musical Instrument Digital Interface (MIDI) port, and a
Game port. Like all National LPC SuperI/O devices, the
PC8739x offers a single-chip solution to the most commonly
used PC I/O peripherals.
The PC8739x family also incorporates: a Floppy Disk Con-
troller (FDC), two enhanced Serial Ports (UARTs), one with
Fast Infrared (FIR, IrDA 1.1 compliant), General-Purpose
Input/Output (GPIO) support for a total of 32 ports, Interrupt
Serializer for Parallel IRQs and an enhanced WATCH-
DOG
timer.
The following features apply to the PC87393F. The feature
lists for other PC8739x devices may differ. See the table on
page 3 for a list of features for each device.
