Figure 10-17 Equivalent Circuit for A/D Loading
10.16 Power Consumption
See Section 10.1 for a list of IDD requirements for the 56F8013/56F8011. 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:
A, the internal [static component], is comprised of the DC bias currents for the oscillator, leakage currents,
PLL, and voltage references. These sources operate independently of processor state or operating
Total power =
A: internal [static component]
+B: internal [state-dependent component]
+C: internal [dynamic component]
+D: external [dynamic component]
+E: external [static]
