How frequently we can write data in flash memory

[sudp]

Hello,

In my project I need to store variable data to persistent memory area of flash memory to retrieve data after power failure. I want to know is there any limit to use this memory? Is it okay to use this memory very frequently?

Thanks,

Hi,

 

Not sure which nRF52-series device you're using, but in general, the Endurance data for the flash is available under this section:

Kind regards,

A specific flash page can be written/erased > 10k cycles on nRF52832:
