GENERAL DESCRIPTION
The FDC37B77x with advanced Consumer IR
and IrDA v1.0 support incorporates a keyboard
interface, SMSC's true CMOS 765B floppy disk
controller, advanced digital data separator, two
16C550A compatible UARTs, one Multi-Mode
parallel port which includes ChiProtect circuitry
plus EPP and ECP, on-chip 12 mA AT bus
drivers, one floppy direct drive support, and
Intelligent Power Management including PME
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
NS16C550A. The parallel port is compatible
with IBM PC/AT architecture, as well as IEEE
1284 EPP and ECP. The FDC37B77x
incorporates sophisticated power control circuitry
(PCC) which includes support for keyboard,
mouse, modem ring and consumer infrared
wake-
up events. The PCC supports multiple low
power-down modes.
The FDC37B77x 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
FDC37B77x may be reprogrammed through the
internal configuration registers. There are 480
I/O address location options, a Serialized IRQ
interface, and three DMA channels.
The FDC37B77x does not require any external
filter components and is therefore easy to use
and offers lower system costs and reduced
board area. The FDC37B77x is software and
register compatible with SMSC's proprietary
82077AA core.
