PSoC 6 MCU

I am trying to gauge the various amounts of current drawn in the PSOC under the various modes of operation. There is LP, ULP, Active, Sleep, Deep Sleep, Hibernate, and Stop modes. A lot to try and make a guess. However, for the PSOC 4, there is an app note that has some rough numbers for Active, Sleep, Deep Sleep, and Hibernate, Stop modes. That is what I am looking for?

I have this app note, but it doesn't have any ball park numbers --

AN219528

Trying to come up with useful numbers based on the data sheet is useless it seems. I am looking for averages and ball parks based on average applications, something just like I was able to find for the PSOC 4. I can test the actual current, but I want to focus my energy on deciding to go with deep sleep or hibernate for example, and the least painful path, but I want data on modes and consumption, ranged data is fine, just something at a glance, I can make a call with.

Thanks,

Andre'

Hi,

If you have our development kit or your custom board, you can program the project and check the power numbers for various low power modes. Link given below. This code example is associated with same application note you are referring to:

https://www.cypress.com/documentation/code-examples/ce226306-psoc-6-mcu-power-measurements

Here are some power numbers we have measured at our side with that code example:

The technology on which PSoC 6 is built consumes lesser power compared to that of PSoC 4. In case of PSoC 4, there is a separate application note, which contains an excel sheet associated with it showing the power numbers. You can give your custom parameters in that excel sheet and estimate the power consumption. Please note that the power numbers for psoc 6 would be much less when compared to psoc4.

Please go through above documentation and update if you have more queries.

Thanks

Thanks -- I hadn't see that app note. Basically, I was torn between deep sleep and hibernate. Looks like my tests show about 10uA for deep sleep with very little going on and 1uA in hibernate. Thus, we will design for deep sleep since its easier to deal with, and if push comes to shove go for hibernate and fiddle with re-starting things on wakeup more which is the problem with hibernate of course.

Thanks for the information --
