1. LPTIM peripheral cannot operate 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.-

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 V_DD supply
voltage conditions summarized in Table 24.
