GENERAL DESCRIPTION
The SMSC FDC37C665GT and FDC37C666GT
Advanced High Performance Multi-Mode
Parallel Port Super I/O Floppy Disk Controller
ICs utilize SMSC's proven SuperCell technology
for increased product reliability and functionality.
The FDC37C665GT is optimized for
motherboard applications while the
FDC37C666GT is oriented towards controller
card applications. Both devices support 1 Mb/s
data rates for vertical recording operation. The
FDC37C665GT is hardware compatible with the
FDC37C651 and FDC37C661 in the Standard
and Enhanced Parallel Port Modes.
The FDC37C665GT and FDC37C666GT
incorporate 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 (FDC37C666GT
only), general purpose address decoder and
four floppy direct drive 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/XT and PC/AT architectures, as well as EPP
and ECP. The FDC37C665GT and
FDC37C666GT incorporate sophisticated power
control circuitry (PCC). The PCC supports
multiple low power down modes.
The FDC37C665GT Floppy Disk Controller
incorporates Software Configurable Logic (SCL)
for ease of use. Use of the SCL feature allows
programmable system configuration of key
functions such as the FDC, parallel port, and
UARTs. The parallel port ChiProtect prevents
damage caused by the printer being powered
when the FDC37C665GT or FDC37C666GT is
not powered. The parallel port backdrive current
protection prevents the FDC37C665GT or
FDC37C666GT from sinking current when the
device is powered off and the printer is left
powered on.
The FDC37C665GT and FDC37C666GT do not
require any external filter components and are,
therefore, easy to use and offer lower system
cost and reduced board area. The
FDC37C665GT and FDC37C666GT are
software and register compatible to the
82077AA using SMSC's proprietary floppy disk
controller core.

DESCRIPTION
IRQ4
O24 FDC37C665GT (Motherboard application):
IRQ4 is the interrupt from the Primary Serial
Port (PSP) or Secondary Serial Port (SSP)
when the PSP or SSP have their address
programmed as COM1 or COM3 (as
defined in the Configuration Registers). The
appropriate interrupt from the Serial Port is
enabled/disabled via the Interrupt Enable
Register (IER). The interrupt is reset
inactive after interrupt service. It is disabled
through IER or hardware reset.

IRQ3
O24 FDC37C666GT (Adapter application):
PSPIRQ is a source of PSP interrupt.
Externally, it should be connected to either
IRQ3 or IRQ4 on PC/AT via jumpers.
O24 FDC37C665GT (Motherboard application):
IRQ3 is the interrupt from the Primary Serial
Port (PSP) or secondary Serial Port (SSP)
when the PSP or SSP have their address
programmed as COM2 or COM4 (as
defined in the Configuration Registers). The
appropriate interrupt from the Serial Port is
enabled/disabled via the Interrupt Enable
Register (IER). The interrupt is reset
inactive after interrupt service. It is disabled
through IER or hardware reset.
