Electrical parameters
9.3.3
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 V_DD or V_SS (no load)
• All peripherals are disabled except if explicitly mentioned.
General conditions for V_DD apply, TA = -40 °C to 125 °C.
