Wakeup time from low-power modes

The wakeup times given in Table 29 are measured starting from the wakeup event trigger up

to the first instruction executed by the CPU:

•

For Stop or Sleep modes: the wakeup event is WFE.

•

WKUP (PC1) pin is used to wakeup from Standby, Stop and Sleep modes.

All timings are derived from tests performed under ambient temperature and VDD=3.3 V.

1. Guaranteed by characterization results.

2. The maximum values have been measured at -40 °C, in worst conditions.

3. The wakeup times are measured from the wakeup event to the point in which the application code reads the first
