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
support for power management and standard AT address
decoding for on-chip functions
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
