USB-101 FT2232H Evaluation Board

USB-101 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 this USB-101 and 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).

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.
