The power estimation spreadsheet provides power consumption estimates based on measured and simulated data; they are provided “as is” and are not guaranteed within a specified precision. Power consumption depends on electrical parameters, silicon process variations, environmental conditions, and use cases running on the processor during operation. Actual power consumption should be verified in the real system. This tool is meant for estimating power consumption during realistic operating modes; it is not intended for power supply sizing. This power estimation spreadsheet is preliminary and subject to change. The spreadsheet mentioned in this document can be downloaded from here.

The input part of the spreadsheet consists of six sections: Operating Performance Point, Processor Core Utilization, LVCMOS IO, Peripheral, Estimated Power, and General. To use the input part the spreadsheet, users must modify the fields with their appropriate usage parameters. Cells designed for user input are in blue. Fields that cannot be modified are red. Fields in green are the output calculated power. Configure the blue cells to a value most closely aligned with your intended scenario.
The purpose of each of the four sections is:
