2.7V DC Spec for I2C Line with 1.8V External Pull-Up
This table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 2.4V to 2.9V and 3.10V to
3.60V, and -40°C<TA <85°C, respectively. Typical parameters apply to 2.7V at 25°C. The I2C lines drive mode must be set to open
drain and pulled up to 1.8V externally.
