Supply Current of I/O modules
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
page 48
Table 26-5.
Table 26-6.
It is possible to calculate the typical current consumption based on the numbers from
on page 393
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 8.9% for the TIMER1, 17.2% for the ADC, and 12.3% for the SPI module. Reading from
Figure 26-100 on page
and F = 1 MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI
enabled, gives:
