Power Consumption for (1-core iMX8MN) vs (4-core iMX8MN with 3 cores shut off in software)

[evancornell]

I have a design using MIMX8MN5DVPIZAA (i.MX 8M Nano UltraLite Quad).

What are the power consumption implications of shutting off 3x cores of MIMX8MN5DVPIZAA in software, compared to populating the board with MIMX8MN1DVPIZAA (i.MX 8M Nano UltraLite Solo) ?

Hello @evancornell 

You can refer to AN12778 for i.MX 8M Nano Power Consumption Measurement and the AN13367 for i.MX 8M Nano Ultra Lite Power Consumption Measurement.

Best regards.

I'm not seeing in either of those two documents the answer to the specific question of power consumption of a 4-core device with 3 cores disabled via software vs a 1-core device. If that information is in those documents, please don't hesitate to point the location out to me.
