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,

Eduard

Hi Eduard,

This is the only specification available, min 1k cycles guaranteed across product temperature specification in Normal Mode (Table 25, footnote 2).

It is not the maximum number of cycles but the minimum number of cycles guaranteed.

Regards,

Daniel
