Current consumption

As the system is being constantly tuned by the PMU described in Functional description, estimating the current consumption of an application can be challenging if the designer is not able to perform measurements directly on the hardware. To facilitate the estimation process, a set of current consumption scenarios are provided to show the typical current drawn from the VDD supply.

Each scenario specifies a set of operations and conditions applying to the given scenario. Current consumption scenarios, common conditions shows a set of common conditions used in all scenarios, unless otherwise is stated in the description of a given scenario. Current consumption scenarios, common conditions describes the conditions used for the modem current consumption specifications. All scenarios are listed in Electrical specification
