FTDI FT232H Single-Channel USB 2.0 Hi-Speed (480Mb/s) to UART / FIFO ICs have the capability of being configured in a variety of industry-standard serial or parallel interfaces. FTDI 232H UART / FIFO ICs feature single-channel USB to serial/parallel ports with a variety of configurations. FT232H devices handle the entire USB protocol on the chip.

These FTDI UART / FIFO ICs are designed for a variety of applications, including single-chip USB to UART (RS232, RS422, or RS485), USB to FIFO, and more. FTDI UM232H USB-to-serial / FIFO development modules use the FT232H chip to handle the USB signaling and protocols. The UM232H module is ideal for development purposes to quickly demonstrate the functionality of adding USB to a target design.


  • Single-channel USB to serial/parallel ports with a variety of configurations
  • Entire USB protocol handled on the chip; no USB specific firmware
    programming required
  • USB 2.0 Hi-Speed (480Mb/s) and Full-Speed (12Mb/s) compatible
  • Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous
    serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design
  • UART transfer data rate up to 12Mbaud (RS232 Data Rate limited by
    external level shifter)
  • CPU-style FIFO interface mode simplifies CPU interface design
  • FTDI's royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases


  • USB instrumentation
  • USB industrial control
  • USB EPOS control
  • USB MP3 player interface
  • USB FLASH card reader/writers
  • Set-top box PC - USB interface
  • USB digital camera interface
  • USB bar code readers
