●The FT4232HQ-R is a 5th generation USB 2.0 High-speed (480Mbps) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces. The IC features 4 UARTs. Two of these have an option to independently configure an MPSSE engine, this allows the IC to operate as two UART/bit-bang ports plus two MPSSE engines used to emulate JTAG, SPI, I²C, bit-bang or other synchronous serial modes.
● Single chip USB to quad serial ports with a variety of configurations
● Entire USB protocol handled on chip, no USB specific firmware programming required
● USB 2.0 high-speed (480Mbps) and full-speed (12Mbps) compatible
● Two multi-protocol synchronous serial engine (MPSSE) on channel A and channel B
