FT8U232AM - USB UART IC

The FT8U232AM is not recommended for new designs - use the FT232BL,FT2232D or FT232RL instead.

The FT8U232AM USB UART is the ideal solution for upgrading legacy RS232 designs to USB.It comes complete with royalty-free drivers for most common operating systems.Features include data transfer rates of up to 3M Baud, a full set of modem handshaking controls and a compact 32LD LQFP package.

The FT245BM is the 2nd generation of FTDI's popular USB FIFO device and the FT245BL is a lead free version of it. The FT245BQ provides the same functionality as the FT245BM and FT245BL in a QFN-32 lead free package.

This device not only adds extra functionality to its predecessor (FT8U245AM) 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 this device in new application areas.
