The FT245R is a USB to parallel FIFO interface, with the new FTDIChip-ID security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to parallel designs using the FT245R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT245R adds a new function compared with its predecessors, effectively making it a 2-in-1 chip for some application areas. A unique number (the FTDIChip-ID) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. The UM245R is supplied on a PCB which is designed to plug into a standard 15.0mm (0.6) wide 24 pin DIP socket. All components used, including the FT245RL are Pb-free (RoHS compliant).
