FT232BM

Product Summary

The FT232BM is the 2nd generation of FTDI popular USB UART I.C. The FT232BM is not only adds extra functionality to its FT8U232AM predecessor and reduces external component count, but also maintains a high degree of pin compatibility with the original, making FT232BM easy to upgrade or cost reduce existing designs as well as increasing the potential for using the FT232BM in new application areas.
