The 82078 Product Family brings a set of enhanced floppy disk controllers. These include several features
that allow for easy implementation in both the portable and desktop market. The current family includes a 64
pin and a 44 pin part in the smaller form factor QFP package. The 3.3V version of the 64 pin part provides an
ideal solution for the rapidly emerging 3.3V platforms. It also allows for a 5.0V tolerant floppy drive interface
that lets the users retain their normal 5.0V drives. Another version of the 64 pin part provides support for 2
Mbps data rate tape drives.
