TBD(5) TBD(5)

TBD stands for to be determined.

Typical values are measured at TA = 25 °C, VDD = 3.3 V, unless otherwise specified.

Data based on characterization results, tested in production at VDDmax and fHCLK max.

To have the Standby consumption with RTC ON, add IDD_VBAT (Low-speed oscillator and RTC ON) to IDD Standby (when

VDD is present the Backup Domain is powered by VDD supply).

Data based on characterization results, not tested in production.
