IMXRT1064 Power Failure Detection

Hi,

      We want to detect power failure in imxrt1064.

      Whenever power failure happens that time we want to write some data in external qspi flash.

      Any way can we monitor power failure ?

Thanks & Regards,

       Vasu

Hi Vasudhevan G ,

    Do you mean your power failure is the power down or power is low?

   You can use the ADC to check the power level, when it is lower than your defined level, but you also need to make sure the power still can let the MCU working, then write the specific data in the flash. You also need to make sure the power down time is slow, and it is enough to write the flash data.

Wish it helps you!

If you still have questions about it, please kindy let me know.

Best Regards,

Kerry
