6.3.5 Wakeup time from Low power mode
The wakeup times given in the following table are measured with the MSI RC oscillator. The
clock source used to wake up the device depends on the current operating mode:
• Sleep mode: the clock source is the clock that was set before entering Sleep mode
• Stop mode: the clock source is the MSI oscillator in the range configured before
entering Stop mode
• Standby mode: the clock source is the MSI oscillator running at 2.1 MHz

mode in both cases. No I/O pins toggling. Not tested in production.
2. HSI oscillator is OFF for this measure.
3. Data based on a differential I
DD measurement between ADC in reset configuration and continuous ADC conversion (HSI
consumption not included).
4. Data based on a differential I
DD measurement between DAC in reset configuration and continuous DAC conversion of
V
DD/2. DAC is in buffered mode, output is left floating.
5. Including supply current of internal reference voltage.
