Note 2.
• Total power consumption = V
When guaranteeing the internal pull-up resistor, use the following formula to calculate its power consumption,
and add the result to the result above.
• Power consumption of internal pull-up resistor = Σ(V
Use the following formula to perform design such that the sum of the power consumption of the device is less
than or equal to the total loss P
This varies depending on the allowable total loss (see the figure below).
