1. Guaranteed by characterization results, unless otherwise specified. 2. Guaranteed by test in production. 3. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8 pF loading capacitors. 4. The supply current in Standby with SRAM2 mode is:
I
DD_ALL
(Standby) + I
DD_ALL
(SRAM2). The supply current in Standby with RTC with SRAM2 mode is:
II
DD_ALL
(Standby + RTC) + I
DD_ALL
(SRAM2).
5. Wakeup with code execution from Flash. Average value given for a typical wakeup time as specified in Table 51: Low-power mode wakeup timings.
