RTC backup
The internal PMU features real-time clock (RTC) based on 32 kHz oscillator, to keep track of date and time.
This feature is supplied by an internal LDO V_RTC, typical 2.3V +-5%.
V_RTC is ‘always on’ when V_BAT supply is present
(>2.5V min).
V_RTC is internally decoupled with 100 nF. When V_BAT is removed from the module, in case RTC
tracking is needed an external supercap is required connected to module pin V_RTC.
