FDC37B78X

Enhanced Super I/O Controller with ACPI Support, Real Time Clock and Consumer IR

SMSC -> Microchip 

GENERAL DESCRIPTION

The FDC37B78x with advanced Consumer IR

and IrDA v1.0 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, on-chip 12 mA AT bus

drivers, and two floppy direct drive support, soft

power management and SMI support and

Intelligent Power Management including PME

and SCI/ACPI 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

FDC37B78x incorporates sophisticated power

control circuitry (PCC) which includes support

for keyboard, mouse, modem ring, power button

support and consumer infrared wake-up events.

The PCC supports multiple low power down

modes.

The FDC37B78x 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

power button override event (4 second button

hold to turn off the system) and either edge

triggered interrupts.

The FDC37B78x provides support for the ISA

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

provides for the recommended functionality to

support Windows '95, PC97 and PC98.

Through internal configuration registers, each of

the FDC37B78x 's logical device's I/O address,

DMA channel and IRQ channel may be

programmed. There are 480 I/O address

location options, 12 IRQ options or Serial IRQ

option, and four DMA channel options for each

logical device.

The FDC37B78x Floppy Disk Controller and

data separator do not require any external filter

components and are therefore easy to use, offer

lower system cost and reduced board area. The

FDC is software and register compatible with

SMSC's proprietary 82077AA core.
