PC87307/PC97307 Plug and Play Compatible and PC97 Compliant SuperI/O
PRELIMINARY
March 1998
PC87307/PC97307 Plug and Play Compatible and PC97
Compliant SuperI/O
Highlights
General Description
The PC87307/PC97307 (VUL) are functionally identical
parts that offer a single-chip solution to the most commonly
used ISA, EISA and MicroChannel
廬
peripherals. This fully
Plug and Play (PnP) compatible chip incorporates a Floppy
Disk Controller (FDC), a Keyboard and mouse Controller
(KBC), a Real-Time Clock (RTC), two fast full function
UARTs, Infrared (IR) support, a full IEEE 1284 parallel port,
three general purpose chip select signals that can be pro-
grammed for game port control, and a separate configura-
tion register set for each module. It also provides support for
power management (including a WATCHDOG timer) and
standard PC-AT address decoding for on-chip functions.
The Plug and Play (PnP) support in the device conforms to
the 鈥淧lug
and Play ISA Specification鈥?/div>
Version 1.0a, May 5,
1994.
The Infrared (IR) interface complies with the IrDA 1.0 SIR
and SHARP-IR standards, and supports all four basic pro-
tocols for Consumer-IR (TV-Remote) circuitry (RC-5, RC-5
extended, RECS80 and NEC).
