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/QFN and
56-pin QVFN packages.
