FD1771 Datasheet | Western Digital

WESTERN DIGITAl MOS/LSI APPLICATION NOTE FLOPPY DISK CONTROLLER APPLICATION NOTE Introduction The FD 1771 is a MOS/LSI device that performs the function of interfacing a processor to a' flexible (Floppy) diskette drive. This single chip replaces nearly 80% of the required disk drive interface electronics. (See figure 1-1) .It provides tha data accessing controls and the bidirectional transfer of information between the processor's memory and the magnetically stored data on the diskette. The diskette data is stored in a data entry format patible with the IBM 3740 specification (other formats may be used providing more data storage). In this format all information is recorded on...
