FT4232H Quad High Speed
The FT4232H is FTDI’s 5
USB devices. The FT4232H is a USB 2.0
High Speed (480Mb/s) to UART/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, I
other synchronous serial modes.
