The SMSC FDC37C665GT and FDC37C666GT
Advanced
Parallel Port Super I/O Floppy Disk Controller
ICs utilize SMSC's proven SuperCell technology
for increased product reliability and functionality.
The
motherboard
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
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

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
