Integrated Host/Disk Interface Drivers  
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.
