PC87317VUL/PC97317VUL SuperI/O Plug and Play
Compatible with ACPI Compliant Controller/Extender
Highlights
General Description
The PC87317VUL/PC97317VUL 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 conforms to the Plug
and Play ISA SpecificationVersion 1.0a, May 5, 1994, and
meets specifications defined in the PC97 Hardware Design
Guide It features a Controller/Extender that is fully compli-
ant with Advanced Configuration and Power Interface (AC-
PI) Revision 1.0 requirements.
Note: All references to the PC87317VUL in this document
also refer to the PC97317VUL, unless otherwise specified.
References which are applicable to the PC97317VUL only
are italicized.
The PC87317VUL incorporates: an advanced Real-Time
Clock (RTC) device that provides both RTC timekeeping and
Advanced Power Control (APC) functionality, a Floppy Disk
Controller (FDC), a Keyboard and Mouse Controller (KBC),
two enhanced Serial Ports (UARTs) with Infrared (IR) sup-
port, a full IEEE 1284 Parallel Port, 24 General-Purpose In-
put/Output (GPIO) bit ports, three general-purpose chip
select signals that can be programmed for game port control
and a separate configuration register set for each module.
The PC87317VUL provides a LED drive output to comply
with PC97 specifications. The chip also provides support for
Power Management (PM), including a WATCHDOG
timer,
and standard PC-AT address decoding for on-chip functions.
The PC87317VUL Infrared (IR) interface complies with the
HP-SIR and SHARP-IR standards, and supports all four ba-
sic protocols for Consumer Remote Control circuitry (RC-5,
RC-5 extended, RECS80 and NEC).
