FT4232H-56Q-REEL

FT4232H-56Q-REEL is FTDI’s 5th generation of USB device. It is a USB 2.0 Hi-Speed (480Mb/s) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces. 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 a variety of configurations, the entire USB protocol is handled on the chip-no USB-specific firmware programming is required, USB 2.0 high speed (480Mbits/second) and full speed (12Mbits/second) compatible, two multi-protocol synchronous serial engines (MPSSE) on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, I²C, SPI, or bit-bang) design.
