JN-AN-1001 Calculating JN5139/JN5148 Power Consumption

This Application Note describes how to calculate the power required by a Jennic JN5139 or JN5148 wireless microcontroller running an IEEE 802.15.4-based application. The formulae necessary to calculate the time required to complete common 802.15.4 network operations are presented in conjunction with the electrical current consumed by the JN5139 and JN5148 devices during these operations. Additionally, timings and current consumption information are provided for JN5139- and JN5148-specific tasks. An example is included that describes how the information presented can be used to determine the battery capacity requirements of an application.
