In conjunction with a mutual capacitive touch  panel, the FT5x06 have user-friendly input functions, which can be applied on many portable devices, such as cellular phones, MIDs,  netbook and notebook personal computers.  The FT5x06 series ICs include FT5206/FT5306/FT5406, the difference of their specifications will be listed individually in this  datasheet.
