Hi all, 

I was trying design system with PSoC6 in Deep Sleep. Used CY8C6347 chip.
Timing diagram as per picture below. Used Wake-up from Deep Sleep from External pin as well as from MCWDT.

After some tests FW Developer came up with issue that entering Deep Sleep is not happening at constant time. "Sometimes it takes up to 500ms". So this is not possible to implement.
Can someone check if entering to Deep Sleep is constant time and if not what is max time to enter?

Hi @MuKh_4408861

Can you please let us know how you are measuring the time taken to enter the DeepSleep state?

The time taken from the instant the deep sleep API is called to actually transitioning to low power mode might vary based on the callbacks present but should not have a drastic impact. Can you please share your implementation so that we can have a look?

Thanks and Regards,
