The FTDI Chip FT4232HA is a USB 2.0 High Speed with 480Mbps 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/Bit Bang ports plus two MPSSE engines used to emulate JTAG, SPI, I 2C, Bit bang or other synchronous serial modes.

USB High Speed to Quad Interface
The FT4232HA integrates a USB protocol engine which controls the physical Universal Transceiver Macrocell Interface
MPSSE Multi Purpose Synchronous Serial Engines
Latency Timer can be altered between 2ms and 255ms
The FT4232HA supports a data transfer rate up to 12 Mbitps when configured as a RS232/RS422/RS485 UART interface
