Power-down Supply Current
ATtiny25/45/85
Example
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 USI, TIMER0, and ADC enabled
at V
add 10% for the USI, 25% for the ADC, and 10% for the TIMER0 module. Reading from
22-9
current consumption in idle mode with USI, TIMER0, and ADC enabled, gives:
