Overview
The FT232BL-TRAY is a USB to UART (Universal Asynchronous Receiver-Transmitter) integrated circuit (IC) developed by FTDI, Future Technology Devices International Ltd. This component is part of the FT232 series and is designed for legacy designs, with recommendations to use the R Family or X Family for new designs. The FT232BL is a lead-free version of the FT232BM and offers a single-chip solution for converting USB signals to asynchronous serial data and vice versa. It is particularly useful for upgrading legacy RS232 peripherals to USB and for interfacing MCU-based designs with USB.
