Wakeup time from low-power mode

The wakeup times given in the following table are measured with the MSI or HSI16 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 either the MSI oscillator in the range configured before

entering Stop mode, the HSI16 or HSI16/4.



Standby mode: the clock source is the MSI oscillator running at 2.1 MHz

All timings are derived from tests performed under ambient temperature and VDD supply

voltage conditions summarized in Table 26.

1. LCD, LPTIM, LPUART peripherals can operate in Stop mode but not in Standby mode.

2.

LSE Low drive consumption is the difference between an external clock on OSC32_IN and a quartz between OSC32_IN

and OSC32_OUT.-
