DP8473AN Floppy Disk Controller For Legacy Interfaces

DP8473AN is designed for systems that must keep a floppy interface for maintenance workflows, archival media, or compatibility testing. It provides controller logic that is software compatible with the µPD765A command set, helping legacy drivers and utilities run without major changes. DP8473AN includes added support logic intended for PC-family designs, which simplifies integration in systems that follow established floppy control conventions. Use it in retrofit controllers, lab fixtures, and long-life industrial equipment where removing the floppy interface is not an option. DP8473AN helps keep signal timing and command handling in hardware so your firmware stays simpler and more predictable during reads, writes, and status polling. Request a quote for DP8473AN.
