Flash reliability S32K146

Hi Sr/ Mdm,


We are using S32K146 and as per datasheet requirements:

NVM reliability specifications when using as Program and Data Flash (attached picture):

nnvmcycp Cycling endurance 1 K — — cycles 2, 3


Does it mean that the maximum number of cycles per each Sector that NXP guarantee for this uC is 1K?

If we do more than 1K reflashing in a cycle test of code reflashing (same sectors), NXP doesn't guarantee the flash reliability after the 1K reflash? Even if reflash is done in a cycle test, thus, all of them during 1day?


Thank you in advance and best regards,
