Figure 25. Typical VBAT current consumption (LSE and RTC ON/backup RAM OFF)
1. The typical current consumption values are given with PDR OFF (internal reset OFF). When the PDR is OFF (internal reset
OFF), the typical current consumption is reduced by additional 1.2 µA.
2. Based on characterization, not tested in production unless otherwise specified.
3. Based on characterization, tested in production.
