Absolute maximum rating

The absolute maximum ratings are rated values which must not be exceeded during operation, even for an instant.

Exceeding the absolute maximum ratings may result in destruction, degradation or other damage to the IC and other

components. When designing applications for this IC, be sure that none of the absolute maximum rating values will ever

be exceeded.

Note1: The withstand voltage for pins (SDA, SCL, RESET) is 5 V.

Note2: For each of 1.5 V and 2.5 V and 3.3 V, system power supply terminal is made into the same voltage.

The maximum potential difference should not exceed rating for all power supply terminals then.

In addition, potential difference between all VSS terminal must be under 0.01 V in this status.

Note3: If you intended to use a temperature higher than Ta = 25°C, reduce by 17.39 mW per one degree (°C) increase.

The case of Ta = 85°C, power dissipation is 696 mW.
