6 Summary of Power for Pre-Populated Use Cases

The following table summarizes the power for the pre-populated use cases. The ARM only, Superset, and Valet Park use cases align to the use cases in the previous section. The MCU only use case uses only a small portion of the device while the remainder is un-powered and is a special case. (The compute core and peripheral loadings can be viewed within the tool.)
