48 / 87 page  Electrical characteristics STM32F101x4, STM32F101x6 48/87 DocID15058 Rev 6 Low-speed internal (LSI) RC oscillator Wakeup time from low-power mode The wakeup times given in Table 25 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 8. 5.3.8 PLL characteristics The parameters given in Table 26 are derived from tests performed under the ambient temperature and VDD supply voltage conditions summarized in Table 8. Table 24. LSI oscillator characteristics (1) 1. VDD = 3 V, TA = –40 to 85 °C unless otherwise specified. Symbol Parameter Min Typ Max Unit fLSI(2) 2.
