Power Consumption
Power consumption of the device according to the different Low Power mode capabilities (backup, wait,
sleep) and active mode.
Power consumption on power supply in different modes: backup, wait, sleep and active.
Power consumption by peripheral: calculated as the difference in current measurement after having enabled
then disabled the corresponding clock.
All power consumption values are based on characterization. Power consumption values are not covered by
test limits in production.
44.4.1 Backup Mode Current Consumption
The backup mode configuration and measurements are defined as follows.
Figure 44-4.
