Electrical characteristics
9.3.2
Supply current characteristics
The current consumption is measured as described in Pin input voltage.
9.3.2.1
Total current consumption in run mode
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 (clock stopped by peripheral clock gating registers) except if
explicitly mentioned.
•
Subject to general operating conditions for VDD and TA.
