rt1064 SNVS/RTC low power domain current consumption

[dmckeever]

What is the expected current consumption of the rt1064 SNVS/RTC low power domain?

We are trying to determine why, in a design with a non-recharegeable coin cell supplying the SNVS/RTC low power domain, and in the absence of other power, the coin cell is exhausted in a few days.

Hi @dmckeever 

We have done measurements with our RT1060 EVK, that you can use as a reference. See the section 5 Power consumption results of the AN12245 Power Consumption and Measurement of i.MX RT1060 

Here is a reference snapshot of the consumption in the SNVS_IN power suply rail. 

Beware that this is done with our EVK and running the  power mode  switch SDK demo. The measurement could change with a custom board and operating range. 

I hope this could help you, if you have further comments do not hestitate to let me know. 

Happy new year.
