Devices are shipped from the factory with flash and EEPROM in the erased state. Data retention specifications
stated in
Typical Data Retention, please refer to Engineering Bulletin EB618.
Freescale Semiconductor
T
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
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.
