1 / 272 page  1 - February 1998 www.national.com © 1998 National Semiconductor Corporation PRELIMINARY February 1998 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 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 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). Outstanding Features Among the most advanced members of National Semicon- ductor’s highly successful SuperI/O family, the PC87317VUL offers: q Full compatibility with ACPI Revision 1.0 requirements q Compliancy with PC97 Hardware Design Guide speci- fications, including PC97 LED support q Advanced RTC, including timekeeping and APC func- tionality q 24 GPIO bit ports q FDC, KBC, two enhanced UARTs, IR support, IEEE 1284 parallel port Block Diagram Real-Time Clock Floppy Disk Controller (FDC) Keyboard + Mouse Controller (KBC) Management (PM) µP Address Floppy Drive Interface Data Handshake Data X-Bus Control Parallel Port (PnP) IRQ Control DMA Channels (RTC and APC) Plug and Play Data and Control General-Purpose I/O (GPIO) Registers I/O Ports Control Control Data and IEEE 1284 (Logical Device 2) (Logical Devices 0 & 1) (Logical Device 8) (Logical Device 4) (Logical Device 7) (Logical Device 3) Ports Serial with IR (UART2) Interface Infrared Interface (Logical Devices 5) Power Serial (UART1) Interface (Logical Devices 6) Serial Port Serial Port TRI-STATE® and WATCHDOG ™ are trademarks of National Semiconductor Corporation.
