Advanced Energy Monitor
8.3 AEM Accuracy and Performance
The AEM is capable of measuring currents in the range of 0.1 µA to 95 mA. For currents above 250 µA, the AEM is accurate within 0.1
mA. When measuring currents below 250 µA, the accuracy increases to 1 µA. Even though the absolute accuracy is 1 µA in the sub
250 µA range, the AEM is able to detect changes in the current consumption as small as 100 nA.
The AEM current sampling rate is 10 kHz.
Note: The AEM circuitry only works when the kit is powered and the power switch is in the AEM position.
8.4 Usage
The AEM data is collected by the board controller and can be displayed by the Energy Profiler, available through Simplicity Studio. By
using the Energy Profiler, current consumption and voltage can be measured and linked to the actual code running on the EFR32 in
realtime.
