1 Endurance is qualified as per JEDEC Standard 22 Method A117 and measured at −40°C, +25°C, +85°C, and +125°C.

2 Retention lifetime equivalent at junction temperature (TJ) = 85°C as per JEDEC Standard 22 Method A117. Retention lifetime derates with junction temperature.

3 Test carried out with all the I/Os set to a low output level.

4 Delay between power supply valid and execution of first instruction by 8052 core.
