PC87310 (SuperI/O^TM)

Dual UART with Floppy Disk Controller

and Parallel Port

Decoding and chip selects for an IDE hard disk

interface

General Description

The PC87310 incorporates two full function UARTs, a flop-

py disk controller (FDC) with analog data separator, one

parallel port, game port decode, hard disk controller de-

code, standard XT/AT address decoding for on-chip func-

tions, and a Configuration Register in one chip. Thus it of-

fers a single chip solution to the most commonly used

Address decoding and strobe generation for a game

port

Fabricated in NSC’s 1.5 m M2CMOS process

Low power CMOS with a power down mode

100-pin EIAJ plastic flatpak package

Integrates all PC-XT , PC-AT logic

IBM PC, XT, and AT peripherals. The floppy disk controller

Ð On chip 24 MHz crystal oscillator

Ð DMA enable logic

is fully compatible with the industry standard 765 architec-

ture, but it includes many more advanced options such as a

high performance data separator, extended track range to

4096, implied seek command, scan command, and both

Ð IBM compatible address decode of A0–A9

Ð 24 mA mP bus interface buffers

Ð 40 mA floppy drive interface buffers

Ð Data rate and drive control registers

Precision analog data separator

Ð Self-calibrating PLL and delay line

Ð Automatically chooses one of three filters

Ð Intelligent read algorithm

standard IBM formats as well as ISO 3.5 formats. The

UARTs are compatible with either the INS8250N-B or the

NS16450. The parallel port, hard disk select, and game port

select logic maintain complete compatibility with the IBM XT

and AT. Hardware selects XT or AT compatibility.

The Configuration Register is one byte wide and can be

programmed via hardware or software. Through its control,

the user can assign standard AT addresses and disable any

major on-chip function (e.g., the FDC, either UART, or the

parallel port) independently of the others. This allows for

flexibility in system configuration when adapter cards con-

tain duplicate functions.

Two pin programmable precompensation modes

Other enhancements

Ð Implied seek up to 4000 tracks

Ð IBM or ISO formatting

Separate interrupt request lines for the parallel and se-

rial ports

Adds or deletes standard asynchronous communication

bits (start, parity, and stop) to or from the serial data

Independently controlled transmit, receive, line status,

and data set interrupts

Features

100% compatible to the IBM PC, XT and AT

architectures

Software compatible to the INS8250N-B, INS8250A and

NS16450 UARTs

Programmable baud generators for each UART channel

divide the input clock by 1 to (2

1) and generate

the internal 16

sample clock

100% compatible to the industry standard 765A

architecture

MODEM control functions for each UART channel

(CTS, RTS, DSR, DTR, RI and DCD)

On-chip analog data separator operates up to 1 Mb/s

Fully programmable serial-interface characteristics:

Ð 5, 6, 7, or 8 bit characters

Ð Even, odd, or no parity generation and detection

Ð 1, 1(/2, or 2 stop bit generation

Implements all DP8473 Floppy Disk Controller functions

Bidirectional parallel port for printer or scanner opera-

tion. Provides all standard Centronics and IBM PC, XT,

and AT interface signals.

High current drive capability for the parallel port
