1) All inputs (including pins configured as inputs) are set at 0 V to 0.1 V or at V_DDP - 0.1 V to V_DDP and all outputs
(including pins configured as outputs) are disconnected.
2) The supply current caused by leakage depends mainly on the junction temperature (see Figure 14) and the
supply voltage. The temperature difference between the junction temperature T_J and the ambient temperature
T_A must be taken into account. As this fraction of the supply current does not depend on device activity, it must
be added to other power consumption values.
3) This formula is valid for temperatures above 0°C. For temperatures below 0°C a value of below 10 μA can be
assumed.
Note: A fraction of the leakage current flows through domain DMP_A (pin V_DDPA). This
current can be calculated as 7,000 × e^-α, with α = 5000 / (273 + 1.3×T_J).
For T_J = 150°C, this results in a current of 160 μA.
