How many times is the life of the UICR & FICR erase or write?

[Rison]

I have found out some data about flash:

Flash memory Endurance 10 000 Write/erase cycles

My question is UICR's life is same ?

If use ERASEUICR will erase all area (eg: NRFHW ) or only are CUSTOMR[1-31] ?

Can I  use UICR for application?

I only want to update CUSTOMR area.

Hi,

 

Flash memory Endurance 10 000 Write/erase cycles

My question is UICR's life is same ?

Yes, this restriction on flash endurance will also apply for UICR.

If use ERASEUICR will erase all area (eg: NRFHW ) or only are CUSTOMR[1-31] ?

The whole UICR region will be erased if you issue a ERASEUICR.

 

Kind regards,

Håkon
