Wakeup time from low-power mode

The wakeup times given in Table 26 are measured on a wakeup phase with an 8-MHz HSI

RC oscillator. The clock source used to wake up the device depends from the current

operating mode:

●

Stop or Standby mode: the clock source is the RC oscillator

●

Sleep mode: the clock source is the clock that was set before entering Sleep mode.

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

voltage conditions summarized in Table 9.

PLL characteristics

The parameters given in Table 27 are derived from tests performed under the ambient

temperature and VDD supply voltage conditions summarized in Table 9.
