PC97317VUL

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 Specification Version 1.0a, May 5, 1994, and meets specifications defined in the PC97 Hardware Design Guide. It features a Controller/Extender that is fully compliant with Advanced Configuration and Power Interface (ACPI) 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) support, a full IEEE 1284 Parallel Port, 24 General-Purpose Input/ 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 WATCHDOGä 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 basic protocols for Consumer Remote Control circuitry (RC-5, RC-5 extended, RECS80 and NEC).
