FT4232HQ-REEL

USB 高速至四通道 串行 UART/JTAG/SPI/I2C IC - QFN-64

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.
