GENERAL DESCRIPTION

The FDC37C93x incorporates a keyboard

interface, real-time clock, SMSC's true CMOS

765B floppy disk controller, advanced digital

data separator, 16 byte data FIFO, two 16C550

compatible UARTs, one Multi-Mode parallel port

which includes ChiProtect circuitry plus EPP

and ECP support, IDE interface, on-chip 24 mA

AT bus drivers, game port chip select and two

floppy direct drive 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, the IDE interface, and the game port select

logic are compatible with IBM PC/AT

architecture, as well as EPP and ECP. The

FDC37C93x incorporates sophisticated power

control circuitry (PCC). The PCC supports

multiple low power down modes.

The FDC37C93x provides support for the ISA

Plug-and-Play Standard (Version 1.0a) and

provides for the recommended functionality to

support Windows '95. Through internal

configuration registers, each of the

FDC37C93x's logical device's I/O address, DMA

channel and IRQ channel may be programmed.

There are 480 I/O address location options, 13

IRQ options, and three DMA channel options for

each logical device.

The FDC37C93x does not require any external

filter components and is, therefore, easy to use

and offers lower system cost and reduced board

area. The FDC37C93x is software and register

compatible with SMSC's proprietary 82077AA

core.
