Example
Table 29-14. ATmega328: Additional Current Consumption (percentage) in Active and Idle
It is possible to calculate the typical current consumption based on the numbers from

Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
14.5% for the TIMER1, 22.1% for the ADC, and 15.7% for the SPI module. Reading from
