GENERAL DESCRIPTION

The FDC37C93xAPM 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,

well

ACCESS.bus, soft power management and SMI

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 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 FDC37C93xAPM incorporates sophisticated

power control circuitry (PCC).

The PCC

supports multiple low power down modes.

The

FDC37C93xAPM

provides

features

for

compliance with the “Advanced Configuration

and Power Interface Specification” (ACPI).

These features include support of both legacy

and ACPI power management models through

the selection of SMI or SCI. It implements a 24-

bit power management timer, power button

override event (4 second button hold to turn off

the system) and either edge triggered interrupts.

The FDC37C93xAPM 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

the

FDC37C93xAPM's logical device's I/O address,

DMA

channel

and

IRQ

channel

may

programmed.

There are 480 I/O address

location options, 13 IRQ options, and three DMA

channel options for each logical device.

The FDC37C93xAPM does not require any

external filter components and is, therefore,

easy to use and offers lower system cost and

reduced board area.

The FDC37C93xAPM is

software and register compatible with SMSC's

proprietary 82077AA core.
