  FT2232H - Hi-Speed Dual USB UART/FIFO IC
The FT2232H is FTDI’s 5th generation of USB devices.  The FT2232H is a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC.  It has the capability of being configured in a variety of industry standard serial or parallel interfaces.

Building on the innovative features of the FT2232, the FT2232H has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.

The FT2232H is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.
