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
DD
= V
DDA
= 3.3 V.
