GENERAL DESCRIPTION

The FDC37C67x with Consumer IR and IrDA

v1.1 support incorporates a keyboard interface,

SMSC's true CMOS 765B floppy disk controller,

advanced digital data separator, two 16C550

compatible UARTs, one Multi-Mode parallel port

which includes ChiProtect circuitry plus EPP

and ECP, on-chip 24 mA AT bus drivers, two

floppy direct drive support, Intelligent power

management and SMI 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 NS16C550.

The parallel

port is compatible with IBM PC/AT architecture,

as well as IEEE 1284 EPP and ECP.

The

FDC37C67x incorporates sophisticated power

control circuitry (PCC).

The PCC supports

multiple low power down modes.

The FDC37C67x 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

FDC37C67x may be reprogrammed through the

internal configuration registers. There are 480

I/O address location options, 8 parallel IRQs, an

optional Serialized IRQ interface, and three

DMA channels.

The FDC37C67x does not require any external

filter components and is therefore easy to use

and offers lower system costs and reduced

board area.

The FDC37C67x is software and

82077AA core.
