A.3.2 NVM Reliability
The reliability of the NVM blocks is guaranteed by stress test during qualification, constant process
monitors and burn-in to screen early life failures.The program/erase cycle count on the sector is
incremented every time a sector or mass erase event is executed
Table A-12 NVM Reliability Characteristics1
NOTES:
1. TJavg will not exeed 85°C considering a typical temperature profile over the lifetime of a consumer, industrial or automotive
application.
Conditions are shown in

2. Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated
to 25
°C using the Arrhenius equation. For additional information on how Freescale defines Typical Data Retention, please
