The power consumption of the TQMa8XxS strongly depends on the application, the mode of operation and the operating
system. For this reason the given values have to be seen as approximate values. Further information about power consumption
and savings can be found in the application note AN12338 from NXP.
The following table shows the power consumption values of the TQMa8XxS at supply voltages of 3.3 V and 5.0 V:
