1. TJavg does not exceed 85°C in a typical temperature profile over the lifetime of a consumer, industrial or automotive
application.
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
refer to Engineering Bulletin EB618
3. Spec table quotes typical endurance evaluated at 25°C for this product family. For additional information on how Freescale
defines Typical Endurance, please refer to Engineering Bulletin EB619.
