1 X-ray exposure may degrade this performance metric.

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

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

4 Retention lifetime equivalent at junction temperature (TJ) = 85°C as per JEDEC Standard 22, Method A117. Retention lifetime decreases with junction temperature. See

Figure 22.

5 The start-up times presented do not include the data capture time, which is dependent on the AVG_CNT register settings.

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