1. Typical data retention values are based on measured response accelerated at high temperature and derated to a constant
2. Data retention is based on T
3. Cycling endurance represents number of program/erase cycles at -40°C ≤ T
4. Write endurance represents the number of writes to each FlexRAM location at -40°C ≤Tj ≤ 125°C influenced by the cycling
