Sleep Mode Current Consumption and Wakeup Time

The Sleep mode configuration and measurements are defined as follows:

Core clock OFF
V_DDIO = V_DDIN = 3.3V
Master Clock (MCK) running at various frequencies with PLLA or the fast RC oscillator
Fast startup through WKUP0–13 pins
Current measurement and associated wake-up time (see Note 1), as shown in the figure below.
All peripheral clocks deactivated
T_A = 25°C

Note: 1. Wake-up time is defined as the delay between the WKUP event and the execution of the first instruction

The following tables provide current consumption and wake-up time in Sleep mode.
