GENERAL DESCRIPTION
The FDC37C67x with Consumer IR and IrDA
v1.1 support incorporates a keyboard interface,
SMSC's true CMOS 765B floppy disk controller,
advanced digital data separator, two 16C550
compatible UARTs, one Multi-Mode parallel port
which includes ChiProtect circuitry plus EPP
and ECP, on-chip 24 mA AT bus drivers, two
floppy direct drive support, Intelligent power
management and SMI 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 is compatible with IBM PC/AT architecture,
as well as IEEE 1284 EPP and ECP. The
FDC37C67x incorporates sophisticated power
control circuitry (PCC). The PCC supports
multiple low power down modes.
The FDC37C67x supports the ISA Plug-and-
Play Standard (Version 1.0a) and provides the
recommended functionality to support Windows
'95.
The I/O Address, DMA Channel and
Hardware IRQ of each logical device in the
FDC37C67x may be reprogrammed through the
internal configuration registers. There are 480
I/O address location options, 8 parallel IRQs, an
optional Serialized IRQ interface, and three
DMA channels.
The FDC37C67x does not require any external
filter components and is therefore easy to use
and offers lower system costs and reduced
board area. The FDC37C67x is software and
register compatible with SMSC's proprietary
82077AA core.
