FTDI Chip offers a wide range of products including modules, cables, and integrated circuits. Driven by its chip development, FTDI’s product focus is on USB connectivity and display interfaces, which have wide applications across all market segments, including; industrial, consumer, PC peripheral, medical, telecom, energy infrastructure, etc.

The FT232R is the latest device to be added to FTDI’s range of USB UART interface Integrated Circuit Devices.
In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device.

Key Hardware Features:
Single chip USB to asynchronous serial data transfer interface.
Entire USB protocol handled on the chip – No USB-specific firmware programming required.
