1) The supply current caused by leakage depends mainly on the junction temperature 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.
2) 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.
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.
The leakage power consumption can be calculated according to the following formulas:
I_LK0 = 500,000 × e^-α with α = 3000 / (273 + B × T_J)
Parameter B must be replaced by
• 1.0 for typical values
• 1.6 for maximum values
I_LK1 = 600,000 × e^-α with α = 5000 / (273 + B × T_J)
Parameter B must be replaced by
• 1.1 for typical values
• 1.4 for maximum values
