Supply Current of IO modules
Example 1
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 23-1.
Table 23-2.
It is possible to calculate the typical current consumption based on the numbers from Table 2 for
other V
Calculate the expected current consumption in idle mode with USI, TIMER0, and ADC enabled
at V
to add 6.1% for the USI, 10.4% for the TIMER0, and 28.8% for the ADC module. Reading from
Figure 23-7
The total current consumption in idle mode with USI, TIMER0, and ADC enabled, gives:
