1. Programming a byte more times than the specified maximum may affect the data integrity of that byte. The byte must be
erased before it can be programming again.
2. Typical endurance was evaluated for this product family. For additional information on how Motorola defines Typical
Endurance, please refer to Engineering Bulletin EB619.
3. 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 Motorola defines Typical Data Retention, please
refer to Engineering Bulletin EB618.
