1. Typical data retention values are based on measured response accelerated at high temperature and derated to a constant
25°C use profile. Engineering Bulletin EB618 does not apply to this technology. Typical endurance defined in Engineering
Bulletin EB619.
2. Cycling endurance represents number of program/erase cycles at -40°C ≤ T
j
≤ 125°C.
