[USB-103]FT2232H Evaluation Board Single type

Last Updated: Wednesday, 14 January 2015

USB-103 FT2232H Evaluation Board Single type

USB-103 is an evaluation board of FTDI's FT2232H. FT2232H supports USB 2.0 Hi-Speed(480Mbps).
You can utilize this board for FT2232H performance estimating, preproduction prototypes, USB communication interfaces for your application and more.

Difference between USB-101 and this USB-103 is number of channels that be connect to user interface.
In USB-101, you can use both channel A and channel B.
In USB-103, you can use channel A and a part of channel B (Tx and Rx).

Specifications (FT2232H)

This is not a specification of USB-103 but of FT2232H.
For more details, please see FTDI's web site.

  • Single chip USB to dual serial / parallel ports with a variety of configurations.
  • Entire USB protocol handled on the chip. No USB specific firmware programming required.
  • USB 2.0 High Speed (480Mbits/second) and Full Speed (12Mbits/second) compatible.
  • Dual Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
  • Dual independent UART or FIFO ports configurable using MPSSEs.
  • Independent Baud rate generators.
  • RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
  • USB to parallel FIFO transfer data rate up to 10Mbyte/sec.
  • Single channel synchronous FIFO mode for transfers > 25 Mbytes/sec.
  • CPU-style FIFO interface mode simplifies CPU interface design.
  • MCU host bus emulation mode configuration option.
  • Fast Opto-Isolated serial interface option.
  • FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
  • Adjustable receive buffer timeout.
  • Option for transmit and receive LED drive signals on each channel.
  • Enhanced bit-bang Mode interface option with RD# and WR# strobes.
  • FT245B-style FIFO interface option with bidirectional data bus and simple 4 wire handshake interface.

  • Asynchronous serial UART interface option with full hardware handshaking and modem interface signals.
  • Fully assisted hardware or X-On / X-Off software handshaking.
  • UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
  • Auto-transmit enable control for RS485 serial applications using TXDEN pin.
  • Operational configuration mode and USB Description strings configurable in external EEPROM over the USB interface.
  • Configurable I/O drive strength (4,8,12 or 16mA) and slew rate.
  • Low operating and USB suspend current.
  • Supports bus powered, self powered and high-power bus powered USB configurations.
  • UHCI/OHCI/EHCI host controller compatible.
  • USB Bulk data transfer mode (512 byte packets in Hi-Speed mode).
  • +1.8V (chip core) and +3.3V I/O interfacing (+5V Tolerant).
