PC97317 Datasheet | National Semiconductor

Description The PC87317VUL/PC97317VUL are functionally identical parts that offer a single-chip solution to the most monly used ISA, EISA and Micro Channel® peripherals. This fully Plug and Play (Pn P) patible 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 pliant 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 ply 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 plies 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). Outstanding Features Among the most advanced members of National Semiconductor’s highly successful Super I/O family, the PC87317VUL offers: q q Full patibility with ACPI Revision 1.0 requirements pliancy with PC97 Hardware Design Guide specifications, including PC97 LED support Advanced RTC, including timekeeping and APC functionality 24 GPIO bit ports FDC, KBC, two enhanced UARTs,...
