The FT4232H is 's 5 generation of USB devices. The FT4232H is a USB 2.0 High Speed (480Mb/s) toUART/MPSSE ICs. The device features 4 UARTs. Two of these have an option to independently configure an MPSSE engine. This allows the FT4232H to operate as two UART/Bit-Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes. The FT4232H has the following advanced features: Single chip USB to quad serial ports with avariety of configurations. Entire USB protocol handled on the chip. No USB specific firmware programming required. USB 2.0 High Speed (480Mbits/Second) and Ful Speed (12Mbits/Second) compatible. Two Multi-Protocol Synchronous Serial Engine (MPSSE) on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, Ic, SPI or bit-bang) design. Baud rate generators RS232/RS422/RS485 UART Transfer Data Rate : up to 12Mbaud. (RS232 Data Rate limited by external level shifter). 's -free Virtual Com Port (VCP) and Direct (D2xx) drivers the requirement for USB driver development in most cases. Adjustable receive buffer timeout. Support for USB suspend and resume conditions via PWREN#, SUSPEND# and RI# pins.
