Power-down Supply Current
Table 26-2.
It is possible to calculate the typical current consumption based on the numbers from
on page 344
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 10.5% for the TIMER1, 16.8% for the ADC, and 12.9% for the SPI module. Reading from
Figure 26-6 on page
and F = 1 MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI
enabled, gives:
