FDC37C669FR

Super I/O Floppy Disk Controller with Fast Infrared Support

SMSC -> Microchip 

GENERAL DESCRIPTION

The SMSC FDC37C669FR PC 95/96

Compatible Super I/O Floppy Disk Controller

with Infrared Support utilizes SMSC's proven

SuperCell technology for increased product

reliability and functionality. The FDC37C669FR

is PC95/96 compliant and is optimized for

motherboard applications. The FDC37C669FR

supports both 1 Mbps and 2 Mbps data rates

and vertical recording operation at 1 Mbps Data

Rate.

The FDC37C669FR 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) as well as Fast

IR and Consumer IR. The parallel port, the IDE

interface, and the game port select logic are

compatible with IBM PC/AT architectures. The

FDC37C669FR incorporates sophisticated

power control circuitry (PCC). The PCC

supports multiple low power down modes.

The FDC37C669FR 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 FDC37C669FR is not powered.

The FDC37C669FR does not require any

external filter components, and is, therefore

easy to use and offers lower system cost and

reduced board area. The FDC37C669FR is

software and register compatible with SMSC's

proprietary 82077AA core.
