FT232BM Datasheet, PDF (1/25 Pages) Future Technology Devices International Ltd. – USB UART ( USB - Serial) I.C.
FT232BM USB UART ( USB - Serial) I.C.
The FT232BM is the 2nd generation of FTDI’s popular USB UART I.C. This device 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 it easy to upgrade or cost reduce existing designs as well as increasing the
potential for using the device in new application areas.
