On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 29. 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 in

Table 29. The power consumption of the analog part of the peripherals (where

applicable) is indicated in each related section of the datasheet.
