• Manufacturer Part Number: FDC37B78X
• Description: Enhanced Super I/O Controller with ACPI Support/ Real Time Clock and Consumer IR
• Manufacturer: SMSC Corporation

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 Management including PME
and SCI/ACPI support. The true CMOS 765B
core provides 100% compatibility with IBM
PC/XT and PC/AT architectures in addition to

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

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.
