More and more applications require an I2C bus voltage of 3.3V or even lower. Tracii XL is the first choice when working with low bus voltages. Alternatively, Connii and Connii MM are also capable of supporting 3.3V applications.
Please note that Tracii 400 is a pure 5V device and will not work with 3.3V referrence voltage. telos offers Levi and Optii to interconnect 5v and 3.3v (and even lower voltage devices) to each other.
