FT232BM

Product Summary

The FT232BM is the 2nd generation of FTDI popular USB UART i.c. The device 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. The applications of the FT232BM include: (1)USB and RS232 Converters; (2)USB and RS422 / RS485 Converters; (3)Upgrading RS232 Legacy Peripherals to USB; (4)Cellular and Cordless Phone USB data transfer cables and interfaces; (5)Interfacing MCU based designs to USB; (6)USB Audio and Low Bandwidth Video data transfer; (7)PDA ó USB data transfer; (8)USB Smart Card Readers; (9)Set Top Box ( S.T.B. ) PC - USB interface; (10)USB Hardware Modems; (11)USB Wireless Modems; (12)USB Instrumentation; (13)USB Bar Code Readers.
