100 nF capacitance needs to be provided between each VDD/VSS pair.

330 nF capacitance needs to be provided between each VDD_LV/VSS_LV supply pair.

470 nF capacitance needs to be provided between VDD_BV and the nearest VSS_LV (higher value may be needed

depending on external regulator characteristics). Supply ramp slope on VDD_BV should always be faster or equal to slope

of VDD_HV. Otherwise, device may enter regulator bypass mode if slope on VDD_BV is slower.

100 nF capacitance needs to be provided between VDD_ADC/VSS_ADC pair.

Full electrical specification cannot be guaranteed when voltage drops below 3.0 V. In particular, ADC electrical

characteristics and I/Os DC electrical specification may not be guaranteed. When voltage drops below VLVDHVL, device is

reset.

Guaranteed by device validation.

Minimum value of TVDD must be guaranteed until VDD reaches 2.6 V (maximum value of VPORH).
