Example
Table 20-2.
It is possible to calculate the typical current consumption based on the numbers from
for other V
Calculate the expected current consumption in idle mode with TIMER0, ADC, and USI enabled
at V
for the TIMER0, 27.3 % for the ADC, and 6.5 % for the USI module. Reading from
on page
The total current consumption in idle mode with TIMER0, ADC, and USI enabled, gives:
