1. V_DD = 3.0 Vdc ± 10%, V_SS = 0 Vdc, T_A = T_A (min) to T_A (max), unless otherwise noted
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Some disturbance of the ADC accuracy is possible during any injection event and is dependent on board layout and power
supply decoupling. This parameter is guaranteed by characterization.
4. Pullups and pulldowns are disabled.
5. Maximum is highest voltage that POR is guaranteed.
6. Maximum is highest voltage that POR is possible.
7. If minimum V_DD is not reached before the internal POR reset is released, RST must be driven low externally until minimum
V_DD is reached.
