58.3.2 Sleep Mode Current Consumption and Wakeup Time

The Sleep mode configuration and measurements are defined as follows:

  • Core clock OFF
  • VDDIO = VDDIN = 3.3V
  • Host 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 following figure
  • All peripheral clocks deactivated
  • TA = 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.
