On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in the table below. The device 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
Ambient operating temperature and supply voltage conditions summarized in Table 21:
Voltage characteristics.
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.
