Table 57.

IWDG min/max timeout period at 40 kHz (LSI) (1)

These timings are given for a 40 kHz clock but the microcontroller’s internal RC frequency can vary from 30

to 60 kHz. Moreover, given an exact RC oscillator frequency, the exact timings still depend on the phasing

of the APB interface clock versus the LSI clock so that there is always a full RC period of uncertainty.
