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 ≤ °C.
3. Write endurance represents the number of writes to each FlexRAM location at -40°C ≤Tj ≤ °C influenced by the cycling
endurance of the FlexNVM (same value as data flash) and the allocated EEPROM backup per subsystem. Minimum and
typical values assume all byte-writes to FlexRAM.
