58.9.1.2 Power Consumption

Backup mode configuration and measurements are defined as follows:
  • POR backup on VDDBU is enabled
  • RTC running
  • Force wake-up (FWUP) enabled
  • Current measurement as per the following figure
Figure 58-42. Measurement on VDDBU

Table 58-61. Current Consumption In Backup Mode
Symbol Parameter Conditions Min Max Unit
IVDDBU Current consumption in Backup mode (VDDBU) VDDBU = 3.3 V – 5 µA

The following figure shows the average Backup mode current consumption measured on a few typical devices.
