Example

Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled at V_CC = 2.0V and F = 1MHz. From the table above, third column, we need to add 8.91% for the TIMER1, 8.12% for the ADC, and 7.96% for the SPI module. Reading fromFigure 1 , we find that the idle current consumption is ~0.06 mA at V_CC = 2.0V and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI enabled, gives:

ICCtotal≃0.06 mA⋅(1 + 0.0891 + 0.0812 + 0.0796)≃0.075mA
