GENERAL DESCRIPTION

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.

The SMSC advanced 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. 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. The I/O Address, DMA Channel and

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.

*The “x” in the part number is a designator that changes depending upon the particular BIOS used inside the specific

chip. “2” denotes AMI Keyboard BIOS and “7” denotes Phoenix 42i Keyboard BIOS.
