I am planning to use CY29421FLXI-ND on 3.3V rail, but looks like I2C port is only spec at 2.5V max. is this correct?
Can i pull up I2C signals to 3.3V for this Clock? is it 3.3V tolerant?

Hi @anonymous-sj ,
When the CY29421 device is e-fused then 2.5 V is the recommended value. For serial communication like I2C you can operate the rails at 3.3 V. You will not experience any issues as the device as 3.3 V tolerant.
Thanks,
Pradipta.
