This is FT234XD-USB to basic UART-IC. This USB2.0 Full Speed IC offers a basic UART to USB bridge in a compact IC package; 3x3mm footprint in a 12 pin, DFN package. The device is a UART, capable of operating up to 3MBaud, with low power consumption (8mA). The FT234XD includes the complete FT-X series feature set, including battery charging detection and enables USB to be added into a system design quickly and easily over a UART interface.


  1. The product may vary in shape, color, and markings as compared to the image shown depending upon availability.
  2. Refer to datasheet in the ATTACHMENTS section for more info. regd. the product.


  1. Single chip USB to asynchronous serial data transfer interface.
  2. Entire USB protocol handled on the chip. No USB specific firmware programming required.
  3. Fully integrated 2048 byte multi-time
  4. programmable (MTP) memory, storing device descriptors and CBUS I/O configuration.
  5. Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue-less interface to external MCU or FPGA.
  6. Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, and RS232) at TTL levels.
  7. 512 byte receive buffer and 512 byte transmit buffer utilising buffer smoothing technology to
    allow for high data throughput.
  8. FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement
    for USB driver development in most cases.
  9. Configurable CBUS I/O pin.
  10. Transmit and receive LED drive signals.
  11. UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
  12. Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.
