Voltage Tolerance of pins of CY22150

Version 1
    Question: Are voltages at the input reference and I2C pins of the CY22150, 5V tolerant?



    The CY22150 has 5V tolerant inputs but it cannot be powered by 5V, it needs to be supplied with 3.3V on the AVDD and VDD pins. The I2C pins are 5V tolerant so you can communicate to the CY22150 with your I2C bus with 5V. The VDDL does not need to be connected if you are not using any of the LCLK outputs.
