ATmega88A: 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 30-5.
Table 30-6.
It is possible to calculate the typical current consumption based on the numbers from
on page 413
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 13.6% for the TIMER1, 26.3% for the ADC, and 21.5% for the SPI module. Reading from

enabled, gives:
