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 FT245RQ comes in a ultra-compact 5x5mm QFN-32 package. A compact 28-Lead SSOP package version of this chip is also available: the FT245RL-Reel. Download FT245R Datasheet
