ATmega165A: Supply Current of I/O modules
ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P
Figure 29-10. ATmega165A: 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.
