1 Operating temperature range is TJ from –40 °C to 150 °C. Typical endurance is evaluated at 25 C. 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 Typical P/E cycles is 100,000 cycles for 128 KB and 256 KB blocks. For additional information on the Freescale
definition of Typical Endurance, please refer to Engineering Bulletin EB619, Typical Endurance for Nonvolatile
Memory.
3 Ambient temperature averaged over duration of application, not to exceed product operating temperature range.
