Power consumption (Naon)

Info Box Applies to Naon

Introduction

Providing maximum power consumption value would be unuseful for the majority of system designer building their application upon Naon module.

Several configurations have been tested in order to provide figures that are measured on real-world use cases instead. Please note that Naon platform is so flexible that is virtually impossible to test for all possible configurations and applications on the market. The use cases here presented should cover most of real-world scenarios. However actual customer application might require more power than values reported here. Generally speaking, application specific requirements have to be taken into consideration in order to size power supply unit and to implement thermal management properly.

Testbed

Measurements have been performed on the following platform:

• Naon SOM: DAF7910C0R
• carrier board: NaonEVB-Lite
• NELK: 1.0.0
• power monitor: INA226 (reference U20 of NaonEVB-Lite schematics).
• ARM Cortex-A8 frequency:
• SDRAM size: 512 MByte
• SDRAM frequency: 400 MHz
• HDVICP2 frequency:
