FDC3400 Datasheet (SMSC) - Floppy Disk Hard Sector Data Handler

FDC3400, Floppy Disk Hard Sector Data Handler

The FDC3400 is an MOS integrated circuit which simplifies the data interface between a processor and a floppy disk drive.

During a write operation, the HSDH receives data from the processor and shifts it out bit-serially to the floppy disk data encoding logic.

Similarly, during a read operation the
