Endurance is qualified as per JEDEC Standard 22 Method A117 and measured at ?40°C, +25°C, +85°C, and +125°C.
Retention lifetime equivalent at junction temperature (T J ) = 85°C as per JEDEC Standard 22 Method A117. Retention lifetime derates with junction temperature.
Test performed with all the I/Os set to a low output level.
Delay between power supply valid and execution of first instruction by 8052 core.
