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 Reduc-
It is possible to calculate the typical current consumption based on the numbers from Table 22-2 for other V
CC and
frequency settings that listed in Table 22-1.
