1 The digital I/O signals are 5 V tolerant.

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 (TJ) = 85°C as per JEDEC Standard 22, Method A117. Retention lifetime depends on junction temperature.

4 The start-up times presented reflect the time it takes for data collection to begin.

5 The RST pin must be held low for at least 15 ns.
