PC87308VUL SuperI/O Enhanced Sidewinder

Plug and Play Compatible Chip, with a

Floppy Disk Controller, a Keyboard

Controller, a Real-Time Clock, Two UARTs, Full

Infrared Support and an IEEE 1284 Parallel Port

General Description

The PC87308VUL is a single chip solution to the most com-

monly used ISA, EISA and Micro Channel peripherals. It in-

corporates in one fully Plug and Play (PnP) compatible chip,

a Floppy Disk Controller (FDC), a Keyboard and mouse

Controller (KBC), a Real-Time Clock (RTC), two full function

UARTs, Universal Infrared (UIR) support, a full IEEE 1284

parallel port, three general purpose chip select signals that

can be programmed for game port control, and a separate

configuration register set for each module. It also provides

The PC87308VUL’s Plug and Play (PnP) support conforms

with the ‘‘Plug and Play ISA Specification’’ Version 1.0a,

May 5, 1994.

The Universal Infrared (UIR) interface complies with the HP-

SIR, SHARP-IR and IrDA-2 standards and supports all four

basic protocols for TV remote circuitry (RC-5, RC-5 extend-

ed, RECS80 and NEC).

Features

support for power management and standard AT address

decoding for on-chip functions.

100% compatibility with Plug and Play requirements

specified in the ‘‘Plug and Play ISA Specification’’, ISA,

EISA, and Micro Channel architectures.
