FT232B - USB UART ICs |
|
FT232R version recommended for new designs
The FT232B is the 2nd
generation of FTDI's popular USB UART device
and the FT232BL is a lead free version of the
FT232BM.
The FT232BQ provides the same functionality as the FT232BL
in a QFN-32 lead free package.
This device not only
adds extra functionality to its predecessor (FT8U232AM)
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.
