PC87322VF (SuperIO

TM III)

Floppy Disk Controller with Dual UARTs

Enhanced Parallel Port and IDE Interface

General Description

The PC87322VF incorporates a Floppy Disk Controller

(FDC) two full function UARTs an enhanced parallel port

and IDE interface control logic in one chip The PC87322VF

includes standard AT address decoding for on-chip func-

tions and a Configuration Register set offering a single chip

solution to the most commonly used ISA EISA and Micro-

Channel

peripherals

The on-chip FDC is software compatible to the PC8477

which contains a superset of the mDP8473 and NEC

m

PD765 and the N82077 floppy disk controller functions

The on-chip analog data separator requires no external

components and supports the 4 MB drive format as well as

the other standard floppy drives used with 525

and 35

media Automatic media sense support is provided

In the PC87322VF the UARTs are equivalent to two

NS16450s or PC16550s The bidirectional parallel port

maintains complete compatibility with the ISA EISA and

MicroChannel parallel ports The enhanced parallel port is

compatible with the IEEE 1284 standard and also supports

EPP Ver 17

The IDE control logic provides a complete IDE interface

with DMA support except for the signal buffers The Config-

uration Registers consist of five byte-wide registers An In-

dex and a Data Register which can be relocated within the

ISA IO address space access the Configuration Registers
