The FDC37B78x with advanced Consumer IR
and IrDA v1.0 support incorporates a keyboard
interface, real-time clock, 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, on-chip 12 mA AT bus drivers, and
two floppy direct drive support, soft power
management and SMI support and Intelligent
Power
SCI/ACPI 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.
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, the IDE interface, and the game port
select logic are compatible with IBM PC/AT
architecture, as well as EPP and ECP.
FDC37B78x incorporates sophisticated power
control circuitry (PCC) which includes support for
keyboard, mouse, modem ring, power button
support and consumer infrared wake-up events.
The PCC supports multiple low power down
modes.

The FDC37B78x provides features for compliance
with the “Advanced Configuration and Power
Interface Specification” (ACPI).
These features include support of both legacy and
ACPI power management models through the
selection of SMI or SCI. It implements a power
button override event (4 second button hold to turn
off the system) and either edge triggered
interrupts.
The FDC37B78x provides support for the ISA
Plug-and-Play
provides for the recommended functionality to
support Windows '95, PC97 and PC98. Through
internal configuration registers, each of the
FDC37B78x 's logical device's I/O address, DMA
channel and IRQ channel may be programmed.
There are 480 I/O address location options, 12
IRQ options or Serial IRQ option, and four DMA
channel options for each logical device.
The FDC37B78x Floppy Disk Controller and data
separator do not require any external filter
components and are therefore easy to use, offer
lower system cost and reduced board area. The
FDC is software and register compatible with
SMSC's proprietary 82077AA core.
