PC87310 (SuperI/O
TM
)
Dual UART with Floppy Disk Controller
and Parallel Port
2
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
IBM
é
PC, XT, and AT peripherals. The floppy disk controller
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
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.
