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.
 Supports bus powered, self-powered and highpower bus powered USB configurations.
 Integrated +3.3V level converter for USB I/O.
 Integrated level converter on UART and CBUS for interfacing to between +1.8V and +5V logic.  True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input.
 Configurable I/O pin output drive strength.
 Integrated power-on-reset circuit.
 Fully integrated AVCC supply filtering - no external filtering required.
 UART signal inversion option.
 +3.3V (using external oscillator) to +5.25V (internal oscillator) Single Supply Operation.
 Low operating and USB suspend current.
 Low USB bandwidth consumption.
 UHCI/OHCI/EHCI host controller compatible.
