ATmega88A: Supply Current of IO Modules
Example
The tables and formulas below can be used to calculate the additional current consumption for
the different I/O modules in Active and Idle mode. The enabling or disabling of the I/O modules
are controlled by the Power Reduction Register. See
details.
Table 29-5.
Table 29-6.
It is possible to calculate the typical current consumption based on the numbers from
on page 412
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 13.6% for the TIMER1, 26.3% for the ADC, and 21.5% for the SPI module. Reading from
Figure 29-147 on page
2.0V and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI
enabled, gives:
