Embedded reference voltage

The parameters given in Table 16, Table 17 are derived from tests performed under ambient

temperature and VDD supply voltage conditions summarized in Table 13: General operating

conditions.

1. Guaranteed by design.

2. No hysteresis when using PVD_IN pin.

3. BOR0 is enabled in all modes and its consumption is therefore included in the supply current characteristics tables.

4. During the first rising edge of VDDCORE, the slope should be less than 2 ms/V to ensure VDDCORE is fully established before

the end of the tVDDCORETEMPO.

5. When exiting from LPLV-Stop mode to RUN mode the rising slope for VDDCORE should be less than 1 ms/V to ensure

VDDCORE is fully established before the end of the tVDDCORETEMPO.
