General Description
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.
Key Features
- o Hard-Sectored Operation - performs all data operations o Single or Double Density Operation- recording code independent o Minifloppy or Standard Floppy compatible o Programmable Sync Byte o Internal Sync Byte Detection and Byte Framing o Fully Double Buffered o Data Overrun/Underrun Detection o Dual Disk Operation - Write on one disk drive while simultaneously reading from another o Tri-State Output Bus for processor compatibility o TTL Compatible Inputs and Outputs .
