On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 27. The MCU is placed
under the following conditions:
• All I/O pins are in analog mode
• 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 and supply voltage conditions summarized in Table 15:
Voltage characteristics
• The power consumption of the digital part of the on-chip peripherals is given
inTable 27. The power consumption of the analog part of the peripherals (where
applicable) is indicated in each related section of the datasheet.
