The FDC37M81x* with IrDA v1.0 support
incorporates a keyboard interface, SMSC's true
CMOS 765B floppy disk controller, advanced
digital data separator, two 16C550A compatible
UARTs, one Multi-Mode parallel port which
includes ChiProtect circuitry plus EPP and ECP,
on-chip 12 mA AT bus drivers, one floppy direct
drive
Management including PME support. The true
CMOS 765B core provides 100% compatibility
with IBM PC/XT and PC/AT architectures in
addition
underflow protection.
digital data separator incorporates SMSC's
patented data separator technology, allowing for
ease of testing and use. Both on-chip UARTs
are compatible with the NS16C550A. The
parallel port is compatible with IBM PC/AT
architecture, as well as IEEE 1284 EPP and
ECP.

FDC37M81x may be reprogrammed through the
internal configuration registers. There are 480
I/O address location options, a Serialized IRQ
interface, and three DMA channels.
The FDC37M81x does not require any external
filter components and is therefore easy to use
and offers lower system costs and reduced
board area. The FDC37M81x is software and
register compatible with SMSC's proprietary
82077AA core.
