FT245BL USB FIFO ( USB - Parallel ) I.C.  
The FT245BL is the lead free version of the 2nd generation of FTDI’s popular USB FIFO I.C. This device not only  
adds extra functionality to its FT8U245AM predecessor and reduces external component count, but also maintains a  
high degree of pin compatibility with the original, making it easy to upgrade or cost reduce existing designs as well as  
increasing the potential for using the device in new application areas.
