On-chip peripheral current consumption

The MCU is placed under the following conditions:

• All I/O pins are in analog input configuration

• All peripherals are disabled unless otherwise mentioned

• The given value is calculated by measuring the current consumption:

– With all peripherals clocked off

– With only one peripheral clocked on

• Ambient operating temperature at 25°C and V

= V

DDA

= 3.3 V
