41 PC87391, PC87392, PC87393, PC87393F 100-Pin LPC SuperI/O Devices for Portable Applications 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 Multiplexer (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 Controller (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 WATCHDOG™ 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.
