特性 Features

·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 (480Mbits/Second) and Full Speed (12Mbits/Second) 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).
·USB to asynchronous 245 FIFO mode for transfer data rate up to 8 MByte/Sec.
·USB to synchronous 245 parallel FIFO mode for transfers up to 40 Mbytes/Sec
·Supports a half duplex FT1248 interface with a configurable width, bi-directional data bus (1, 2, 4 or 8 bits wide).
·CPU-style FIFO interface mode simplifies CPU interface design.
·Fast 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.
