What is the tolerance of I2C Open-drain voltage?
Device : CYUSB306x.
If VDDIO1:1.8V, Is it possible that I2C Pull-up Voltage is 3.3V ?
If damage, I will use I2C level-shift.
CYUSB306x datasheet is below;
thanks,

We recommend you to use I2C level-shift in this case. It may be harmful if you pull-up I2C/SCL and I2C/DAT to 3.3V directly.
