The FT232R is a USB to serial UART interface with the following advanced features: 

Single chip USB to asynchronous serial data transfer interface. 

Entire USB protocol handled on the chip. No USB specific firmware programming required. 

Fully integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration.

Fully integrated USB termination resistors.

Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue-less interface to external MCU or FPGA. 

Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232) at TTL levels.

128 byte receive buffer and 256 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.

 FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.

Unique USB FTDIChip-ID™ feature. 

Configurable CBUS I/O pins.

Transmit and receive LED drive signals.

 UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity

FIFO receives and transmits buffers for high data throughput.

Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.

Device supplied pre-programmed with unique USB serial number.
