Example

Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled at VCC = 2.0V and F = 1MHz. From the table above, third column, we need to add 12.28% for the TIMER1, 19.74% for the ADC, and 15.63% for the SPI module. Reading from Figure 1, we find that the idle current consumption is ~0.036 mA at VCC = 2.0V and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI enabled, gives:

ICCtotal0.036 mA(1 + 0.123 + 0.197 + 0.156)0.053mA
