Note:
1. Current consumption of the module only. To calculate the total internal power consumption of the
microcontroller, add this value to the base power consumption given in “Power Consumption”
section in electrical characteristics.
2. CPU in Standby mode.
3. Average power consumption with ADC active in Free-Running mode.

Note:
1. For design guidance only and not tested in production.
2. A slope faster than the maximum rating can trigger a reset of the device if changing the voltage
level after an initial power-up.
