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.
