2 100 nF EMI capacitance and 10 µF bulk capacitance need to be provided between each of the four VDD_LV/VSS_LV
supply pairs. For details refer to the Power Management chapter of the MPC5646C Reference Manual.
3 This voltage is internally generated by the device and no external voltage should be supplied.
4 100 nF capacitance needs to be provided between VDD_ADC/VSS_ADC pair.
5 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.
6 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.
7 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.
8 Guaranteed by the device validation.
