PC87332VLJ (3 3V 5V) and PC87332VLJ-5 (5V)
(SuperI O
TM
III Premium Green)
Floppy Disk Controller Dual UARTs IEEE1284
Parallel Port and IDE Interface
General Description
The PC87332VLJ and PC87332VLJ-5 are single chip solu-
tions for most commonly used I O peripherals in ISA EISA
and MicroChannel based computers It incorporates a
Floppy Disk Controller (FDC) two full featured UARTs an
IEEE 1284 compatible parallel port and all the necessary
control logic for an IDE interface Standard PC-AT address
decoding for all the peripherals and a set of configuration
registers are also implemented in this highly integrated
member of the SuperI O family Advanced power manage-
ment features and mixed voltage operation in the VLJ ver-
sion make the PC87332 chips an ideal for low-power and or
portable personal computer applications
The PC87332 FDC uses a high performance digital data
separator eliminating the need for any external filter compo-
nents It is fully compatible with the PC8477 and incorpo-
rates a superset of DP8473 NEC
mPD765
and N82077 flop-
py disk controller functions All popular 5 25 and 3 5 flop-
py drives including the 2 88 MB 3 5 floppy drive are sup-
ported In addition automatic media sense and 2 Mbps tape
drive support are provided by the FDC
The two UARTs are fully NS16450 and NS16550 compati-
ble Both ports support MIDI baud rates
