ATmega48PB/88PB/168PB

35.1.3.1 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 12.28% for the TIMER1, 19.74% for the ADC, and 15.63% for the SPI module. Reading from Figure 35-6, we find that the idle current consumption is ~0.036 mA at V_CC = 2.0V and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI enabled, gives:

I CC total ≃ 0.036 mA \cdot (1 + 0.123 + 0.197 + 0.156) ≃ 0.053mA
