The FT120 provides a cost and feature optimized USB full-speed device controller. The design closely matches the PDIUSBD12 and may be used as a drop in replacement for the device. Communicating with a micro-controller over the generic parallel interface the device will appear as another memory device on the processor bus, offering USB connectivity with bulk, isochronous or interrupt endpoints.
