The FT4232HA is FTDI’s 5th generation of USB devices. The FT4232HA is a USB 2.0 High Speed (480Mb/s) to UART/MPSSE IC that is automotive qualified for AEC temperature grade 2. The device features four UARTs. Two of these have an option to independently configure an MPSSE engine. This allows the FT4232HA to operate as two UART/BitBang ports plus two MPSSE engines used to emulate JTAG, SPI, I 2C, Bit-bang or other synchronous serial modes.
