FT120T [FTDI]

FT120 – USB full-speed device controller

Note that FT120Q is now under EOL and is not recommended for new designs,however the FT120T is still available.

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.

FT120Q is in QFN-28 packaging. FT120T is available in TSSOP-28 packaging.
