1
Specifications guaranteed by design.
2
Endurance is qualified as per JEDEC Standard 22 Method A117 and measured at −40°C, +25°C, +85°C, and +125°C.
3
Retention lifetime equivalent at junction temperature (T
J
) = 85°C as per JEDEC Standard 22 Method A117. Retention lifetime derates with junction temperature.
4
Recommended crystal specifications.
5
Test carried out with all the I/Os set to a low output level.
6
Delay between power supply valid and execution of first instruction by 8052 core.
