we are working stm32wle5ccu6. In than I am trying to put device in power saving mode but its not working properly.
I was getting 15 mA consumption before now after reducing clock freq, I am getting 5.51mA.. we want to achieve consumption in microamps,
I tried Stop mode and even sleep mode. But in that mode also the consumption stays same as 5 mA, and also the pulse count stops.
We need GPIO to run continuously so that we get pulse count correct.
can someone help on this.

Hello @Rohit_Shinde
Have you tried to follow the same implementations used on our PWR LL and PWR HAL examples. They should really help you to understand what you need to do.
Best Regards.
STTwo-32

What hardware are you using ?
How to write your question to maximize your chances to find a solution
Are you sure that the current you measure is just the STM32 and nothing else?
Remember that you must physically disconnect any debug probe to get true low-power readings.
You may need to power-cycle (not just reset) the target after disconnecting a debugger.
A complex system designed from scratch never works and cannot be patched up to make it work.
