PC87311APC87312 (SuperIO

TM IIIII)

Floppy Disk Controller with Dual UARTs

Parallel Port and IDE Interface

General Description

The PC87311A12 incorporates a floppy disk controller

(FDC) two full function UARTs a bidirectional parallel port

and IDE interface control logic in one chip The PC87311A

includes standard ATXT address decoding for on-chip

functions and a Configuration Register offering a single

chip solution to the most commonly used IBM

PC

PC-XT

and PC-AT

peripherals The PC87312 includes

standard AT address decoding for on-chip functions and a

Configuration Register set offering a single chip solution to

the most commonly used ISA EISA and Micro Channel pe-

ripherals

The on-chip FDC is software compatible to the PC8477

which contains a superset of the DP8473 and NEC mPD765

and the N82077 floppy disk controller functions The on-

chip analog data separator requires no external compo-

nents and supports the 4 Mb drive format as well as the

other standard floppy drives used with 525

and 35

me-

dia

In the PC87311A

the UARTs are equivalent to two

INS8250N-Bs or NS16450s The bidirectional parallel port

maintains complete compatibility with the IBM PC XT and

AT In the PC87312 the UARTs are equivalent to two

NS16450s or PC16550s The bidirectional parallel port

maintains complete compatibility with the ISA EISA and Mi-

cro Channel parallel ports

The IDE control logic provides a complete IDE interface ex-

cept for the signal buffers The Configuration Registers con-

sist of three byte-wide registers An Index and a Data Regis-

ter which can be relocated within the ISA IO address space

access the Configuration Registers
