Read/write cycle life of RTC backup registers (STM32F373)

Hi all,

 

I'am using STM32F373 MCU, in my application, the RTC backup registers updated every 10 minutes.

 

I know some memory cycles limit read/write cycles, Eg, Eeprom memory only allows 10000 write /read  cycles, if greater than that eeprom will die.

 

So, I wonder RTC backup registers have the same Epprom memory operations? Can I do multiple reads/writes cycle without fear of RTC Backup registers death?

 

Please confirm for me !
Thank in advance,

 

Viet Tran
