GENERAL DESCRIPTION

The FDC37C93xFR with Fast IR support

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, as well as ACCESS.bus, soft 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, the IDE interface, and the game port select

logic are compatible with IBM PC/AT

architecture, as well as EPP and ECP. The

FDC37C93xFR incorporates sophisticated

power control circuitry (PCC). The PCC

supports multiple low power down modes. The

FDC37C93xFR 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

FDC37C93xFR'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

FDC37C93xFR does not require any external

filter components and is, therefore, easy to use

and offers lower system cost and reduced board

area. The FDC37C93xFR is software and

register compatible with SMSC's proprietary

82077AA core.
