Doc ID 17478 Rev 4

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.

Both the relative and the fixed conditions must be met. For instance: If VDD_HV_A is 5.9 V, VDD_HV_ADC0 maximum value is

6.0 V then, despite the relative condition, the max value is VDD_HV_A + 0.3 = 6.2 V.

PA3, PA7, PA10, PA11 and PE12 ADC_1 channels are coming from VDD_HV_B domain hence VDD_HV_ADC1 should be

within ±100 mV of VDD_HV_B when these channels are used for ADC_1.

Guaranteed by the device validation.
