The
interface, 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
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 EPP and ECP.
The FDC37B72x incorporates sophisticated power
control circuitry (PCC) which includes support for
keyboard, mouse, modem ring, power button
support and other wake-up events.
supports multiple low power down modes.
The FDC37B72x 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.

options, 12 IRQ pin options or Serial IRQ option,
and four DMA channel options for each logical
device.
The FDC37B72x 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
