2. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8 pF loading capacitors.

3. The supply current in Standby with SRAM2 mode is:

IDD_ALL(Standby) + IDD_ALL(SRAM2). The supply current in Standby with RTC with SRAM2 mode is:

IDD_ALL(Standby + RTC) + IDD_ALL(SRAM2).

4. Wakeup with code execution from Flash. Average value given for a typical wakeup time as specified in Table 52: Low-power mode wakeup timings.
