Power estimate calculation anyone?

[EdSutter]

We are considering using the i.MXRT1170 on a project that is somewhat power constrained (runs on battery).  Is there any tool that helps with this?  For example it would be nice to be able to check off all the modules I plan to use and then get an estimate of the power consumption (of just the i.MXRT1170) with those blocks active.

Hi EdSutter, if there's a tool like that out there, I haven't come across it yet. McuXpresso doesn't do this yet.

Have you looked at Section 4.1.5 of IMXRT1170CEC datasheet? It's not as drilled down as you'd like but it does cover a lot of scenarios.

@eamonnheffernan Yep, that's exactly what I've been referring to up to this point.  Its a good first-shot estimate, with the caveat of the last two bullet items in each of the configurations...

• All PLLs are enabled
• All peripherals are enabled...

Thanks,

Hello EdSutter,

There is not a power estimate calculator available per se, albeit as Eamonn said there are some typical power mode supply currents that may serve as reference.

As for additional resources, Application Note 13148 (link below) has some more details on how to handle the low-power modes on the i.MXRT1170 to optimize for your application.

My apologies for the inconvenience.

Gustavo

@gusarambula Thanks, I didn't see that...
