Notes 2. This varies depending on the allowable total loss (see the figure below).
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
Total power consumption = V
Caution When using the internal pull-up resistor, calculate and add the separate power
consumption.
