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 46
Table 27-1.
Table 27-2.
It is possible to calculate the typical current consumption based on the numbers from
on page 340
Calculate the expected current consumption in idle mode with TIMER1, ADC, and SPI enabled
at V
to add 8.0% for the TIMER1, 19.8% for the ADC, and 13.2% for the SPI module. Reading from
Figure 27-7 on page 337
and F = 1MHz. The total current consumption in idle mode with TIMER1, ADC, and SPI enabled,
gives:
