Features:
1. Single channel USB to serial / parallel ports with a variety of configurations.
2. Entire USB protocol handled on the chip. No USB specific firmware programming required.
3. USB 2.0 Hi-Speed (480Mbits/Second) and Full Speed (12Mbits/Second) compatible.
4. Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI (MASTER) or bit-bang) design.
5. UART transfer data rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
6. USB to asynchronous 245 FIFO mode for transfer data rate up to 8 Mbyte/Sec.
7. USB to synchronous 245 parallel FIFO mode for transfers upto 40 Mbytes/Sec
8. Supports a proprietary half duplex FT1248 interface with a configurable width, bi-directional data bus (1, 2, 4 or 8 bits wide).
9. CPU-style FIFO interface mode simplifies CPU interface design.
10. Fast serial interface option.
11. FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
12. Adjustable receive buffer timeout.
