FDC37C669-MS

PC 98/99 Compliant Super I/O Floppy Disk Controller with Infrared Support

SMSC -> Microchip 

GENERAL DESCRIPTION

The SMSC FDC37C669 PC 95 Compatible Super I/O

Floppy Disk Controller with Infrared Support utilizes

SMSC's proven SuperCell technology for increased

product reliability and functionality. The FDC37C669 is

PC95 compliant and is optimized for motherboard

applications. The FDC37C669 supports both 1 Mbps and

2 Mbps data rates and vertical vertical recording

operation at 1 Mbps Data Rate.

The FDC37C669 incorporates 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 12 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. One UART includes additional

support for a Serial Infrared Interface, complying with

IrDA,

HPSIR,

and ASKIR

formats (used by Sharp, Apple Newton, and other PDAs).

The parallel port, the IDE interface, and the game port

select logic are compatible with IBM PC/AT

architectures. The FDC37C669 incorporates

sophisticated power control circuitry (PCC). The PCC

supports multiple low power down modes.

The FDC37C669 Floppy Disk Controller incorporates

Software Configurable Logic (SCL) for ease of use. Use

of the SCL feature allows programmable system

configuration of key functions such as the FDC, parallel

port, and UARTs. The parallel port ChiProtect prevents

damage caused by the printer being powered when the

FDC37C669 is not powered.

The FDC37C669 does not require any external filter

components, and is, therefore easy to use and offers

lower system cost and reduced board area. The

FDC37C669 is software and register compatible with

SMSC's proprietary 82077AA core.
