ATmega168A Supply Current of IO Modules
Example
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 30-9.
Table 30-10. ATmega168A: Additional Current Consumption (percentage) in Active and Idle
It is possible to calculate the typical current consumption based on the numbers from
12 on page 463
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 10.3% for the TIMER1, 20.3% for the ADC, and 17.1% for the SPI module. Reading from
Figure 30-241 on page

enabled, gives:
