Supply Current of I/O modules
Figure 27-10. Idle Supply Current vs. V
The tables and formulas below can be used to calculate the additional current consumption for
the different I/O modules in Active and Idle mode. The enabling or disabling of the I/O modules
are controlled by the Power Reduction Register. See
details.
Table 27-1.

It is possible to calculate the typical current consumption based on the numbers from
