Introduction

The FT232BM is the 2nd generation of FTDI's popular USB UART device and the FT232BL is a lead free version of it. The FT232BQ provides the same functionality as the FT232BM and 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.
