1 / 218 page  www.national.com 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). Features s 100% compatible with Plug and Play requirements specified in the “ Plug and Play ISA Specification”, ISA, EISA, and MicroChannel architectures s Meets PC97 requirements PRELIMINARY March 1998 PC87307/PC97307 Plug and Play Compatible and PC97 Compliant SuperI/O Highlights Block Diagram Real-Time Clock (Logical Device 2) Floppy Disk Controller (FDC) with Digital Data Separator (DDS) (PC8477) High Current Driver Keyboard Controller (KBC) Power Management Logic µP Address Floppy Drive Interface Data Handshake Data Serial Two UARTs + IR (16550 or 16450) X-Bus IEEE1284 Control Parallel Port Interface Infrared Interface Ports (PnP) IRQ Control DMA Channels (Logical Devices 5 & 6) Interrupt (RTC and APC) Plug and Play (Logical Device 8) (Logical Device 0) Data and Control (Logical Device 3) Data and Mouse Controller (Logical Device 1) General Purpose I/O Registers (Logical Device 7) I/O Ports Data and Control (Logical Device 4) Control Control © 1998 National Semiconductor Corporation TRI-STATE® is a registered trademark of National Semiconductor Corporation.
