113 / 200 page  DocID028800 Rev 1 113/200 STM32L431xx Electrical characteristics 168 6.3.8 Internal clock source characteristics The parameters given in Table 47 are derived from tests performed under ambient temperature and supply voltage conditions summarized in Table 21: General operating conditions. The provided curves are characterization results, not tested in production. High-speed internal (HSI16) RC oscillator Table 47.
