Supply current characteristics

Total current consumption

The MCU is placed under the following conditions:

●

All I/O pins in input mode with a static value at VDD or VSS (no load)

●

All peripherals are disabled except if explicitly mentioned.

Subject to general operating conditions for VDD and TA.
