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.

- JTAG signals are 5V to 1.8V tolerant
- ARM Muli-ICE 20-pin header compatible.
- Separate SPI/I2C/Serial interfaces
- Configurable output of RS232 (MAX3243) or TTL level for serial communication
