GENERAL DESCRIPTION

The FDC37B77x with advanced Consumer IR

and 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

addition

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

FDC37B77x

incorporates sophisticated power control circuitry

(PCC) which includes support for keyboard,

mouse, modem

ring

and consumer infrared

wake-

up events.

The PCC supports multiple low

power-down modes.

The FDC37B77x supports the ISA Plug-and-Play

Standard

(Version

1.0a)

and

provides

the

recommended functionality to support Windows

'95.

The I/O Address, DMA Channel and

hardware IRQ of each logical device in the

FDC37B77x 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 FDC37B77x does not require any external

filter components and is therefore easy to use

and offers lower system costs and reduced

board area.

The FDC37B77x is software and

82077AA core.
