    PsoC4 and accelerometer I2C compatibility

      Hello,

         

      I would like to use I2C for communication between my PSoC 4 chip and accelerometer with 1.8V supply (logic level). I am not sure if I need use a level shifter or they can be connected directly. Would like to use 2.7V supply for the PSoC.
