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
