22.3.1 Example
Calculate the expected current consumption in idle mode with USI, TIMER0, and ADC enabled at V
CC
= 2.0V and f
= 1 MHz. From Table 22-2 on page 177, third column, we see that we need to add 10% for the USI, 25% for the
ADC, and 10% for the TIMER0 module. Reading from
Figure 22-9, we find that the idle current consumption is
~0,18 mA at V
CC
= 2.0V and f = 1 MHz. The total current consumption in idle mode with USI, TIMER0, and ADC
enabled, gives:
22.4 Power-down Supply Current
