GENERAL DESCRIPTION
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 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 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 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
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.
