1. ESR is the equivalent series resistance and ESL is the equivalent inductance.
Supply current characteristics
The current consumption is measured as described in
Total current consumption in run mode
The MCU is placed under the following conditions:
•
•
Subject to general operating conditions for V
All I/O pins in input mode with a static value at V
All peripherals are disabled (clock stopped by peripheral clock gating registers) except if
explicitly mentioned.
