The FT4232H is FTDI’s 5th generation of USB devices. The FT4232H is a USB 2.0 Hi-Speed (480Mb/s) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces.
The FT4232H 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, I2C, Bit-bang or other synchronous serial modes.
The FT4232H is available in Pb-free (RoHS compliant) 64-pin LQFP/QFN and 56-pin VQFN packages. The 56-pin VQFN with lower pin count and small size package is also available for the FT4232H. The differences exist on power/ground and pin number for each pin. The part number is FT4232H-56Q to distinguish it from the 64-pin package type. All the functions are supported in the 56-pin VQFN package.
