On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in the table below. The MCU is

placed under the following conditions:

•

All I/O pins are in analog mode.

•

The given value is calculated by measuring the difference of the current consumptions:

–

when the peripheral is clocked on

–

when the peripheral is clocked off

•

The ambient operating temperature and supply voltage conditions are summarized

in Table 32.

•

The power consumption of the digital part of the on-chip peripherals is given in the table

below. The power consumption of the analog part of the peripherals (where applicable)

is indicated in each related section of the datasheet.
