Overview

The TIAO USB Multi Protocol Adapter (TUMPA) is a multi-functional USB communication adapter for hobbyists or engineers. The adapter is based on FDTI's flagship communication chip FT2232H, a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.
