Power-down Supply Current
Table 29-2.
It is possible to calculate the typical current consumption based on the numbers from
on page 328
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 16.1% for the TIMER1, 15.5% for the ADC, and 13.4% for the SPI module. Reading from
Figure 29-6 on page 325
and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI enabled,
gives:
