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
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 “Plug and Play ISA Specification” 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).
