NOTES:
1 Typical endurance is evaluated at 25 oC. Product qualification is performed to the minimum specification. For
additional information on the Freescale definition of Typical Endurance, please refer to Engineering Bulletin EB619,
Typical Endurance for Nonvolatile Memory.
2 Ambient temperature averaged over duration of application, not to exceed product operating temperature range.
