10.16 Power Consumption
See Section 10.1 for a list of IDD requirements for the 56F8014. This section provides additional detail
which can be used to optimize power consumption for a given application.
Power consumption is given by the following equation:
Total power =
A: internal [static component]
+B: internal [state-dependent component]
