PSoC 4 MCU

We are completing a design using the CY8C4124LQI-443, we intended to place the device in STOP mode, but when we tried we discovered that the device does not support it. 

OK, but that is not mentioned anywhere.  I have looked at the DS, low power app note, and online search guides, where can we determine which low power modes each family supports?

I need this data ASAP as we are finalizing our design now.

Hi @HeGi_2497906 , You should be able to find this information in the device datasheet. Please look at section Power System under System resources. Also, as per device datasheet, hibernate mode is supported in PSoC 4100 family.

Alternatively, you can find this information in the PSoC 4 System Reference Guide. Power modes are implemented as part of the Cy_Boot component. Therefore, open PSoC Creator -> Help menu-> System Reference guide. Under Cy_boot section open PSoC 4 System Reference Guide - cy_boot Component v5.90 (depends on the version you are using). In that you will find the following table under Power Management chapter that lists the power modes available in different families of PSoC 4.

Can you please let us know why you were not able to use the hibernate mode in this device? How did you test this?

Regards,
