The FDC37C93xAPM 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, IDE interface, on-chip 24 mA
AT bus drivers, game port chip select and two
floppy direct drive support, as well as
ACCESS.bus, soft 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, the IDE interface, and the
game port select logic are compatible with IBM
PC/AT architecture, as well as EPP and ECP.
The FDC37C93xAPM incorporates sophisticated
power control circuitry (PCC). The PCC
supports multiple low power down modes.
These features include support of both legacy
and ACPI power management models through
the selection of SMI or SCI. It implements a 24-
bit power management timer, power button
override event (4 second button hold to turn off
the system) and either edge triggered interrupts.
The FDC37C93xAPM provides support for the
ISA Plug-and-Play Standard (Version 1.0a) and
provides for the recommended functionality to
support Windows '95. Through internal
configuration registers, each of the
FDC37C93xAPM's logical device's I/O address,
DMA channel and IRQ channel may be
programmed. There are 480 I/O address
location options, 13 IRQ options, and three DMA
channel options for each logical device.
The FDC37C93xAPM does not require any
external filter components and is, therefore,
easy to use and offers lower system cost and
reduced board area. The FDC37C93xAPM is
software and register compatible with SMSC's
proprietary 82077AA core.
The FDC37C93xAPM provides features for
compliance with the “Advanced Configuration
and Power Interface Specification” (ACPI).
