NOTE

Stresses exceeding the recommended absolute maximum ratings may cause permanent

damage to the device. This is a stress rating only and functional operation of the device at

these or any other conditions above those indicated in the operational sections of this

specification are not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability. During overload conditions

(VIN > VDD_HV_A/HV_B or VIN <VSS_HV), the voltage on pins with respect to ground

(VSS_HV) must not exceed the recommended values.

DD_HV_B can be independently controlled from VDD_HV_A. These can ramp up or ramp down in any order. Design

is robust against any supply order.

2 This voltage is internally generated by the device and no external voltage should be supplied.

3 Both the relative and the fixed conditions must be met. For instance: If V

DD_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.

4 PA3, PA7, PA10, PA11 and PE12 ADC_1 channels are coming from V

DD_HV_B domain hence VDD_HV_ADC1 should

be within ±300 mV of VDD_HV_B when these channels are used for ADC_1.

5 Any temperature beyond 125 °C should limit the current to 50 mA (max).

6 This is the storage temperature for the flash memory.
