• Manufacturer Part Number: FDC37M81x
• Description: PC98/99 Compliant Enhanced Super I/O Controller
• Manufacturer: SMSC Corporation

•
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 support, and Intelligent Power Management
including PME support. The true CMOS 765B
core provides 100% compatibility with IBM
PC/XT and PC/AT architectures in addition to
providing data overflow and underflow protection.
incorporates SMSC's patented data separator
technology, allowing for ease of testing and use.
NS16C550A. The parallel port is compatible with
IBM PC/AT architecture, as well as IEEE 1284
EPP and ECP. The FDC37M81x incorporates
sophisticated power control circuitry (PCC) which
includes support for keyboard, mouse, and
modem ring wake-up events. The PCC supports
multiple low power-down modes.

The FDC37M81x supports the ISA Plug-and-Play
Standard (Version 1.0a) and provides the
recommended functionality to support Windows
'95/’98.
hardware IRQ of each logical device in the
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.
