i go through with datasheet related to low power mode. i did not get understand.

There should be SLEEP and STANDBY examples under the CubeF4 trees for this and other boards. Look at PWR and RTC forks.

You'll probably need to add the LSE crystal and parts to the board to allow the RTC to run in low power mode.

The board also has a lot of ancillary parts that probably won't help achieve "low power" operation in the measurable sense ​

i am using HSE for RTC

I doubt that's going to work in STANDBY.

T​he simplists low power method is to use __WFI() in an idle loop.
