White Paper on Automotive-Grade RTC Chip Selection: 5 Core Parameters Determining System Reliability

In 2025, China's new energy vehicle (NEV) penetration rate exceeded 50%, and the number of RTC chips per vehicle increased from 1 to 3–5. However, according to industry surveys, 37% of Tier 1 engineers experienced mass production rework due to neglecting key parameters during selection. Automotive-grade RTC selection is by no means a simple comparison of accuracy—hidden indicators such as temperature drift, power consumption curves, and EMC immunity are often the watershed determining system reliability. Based on the AEC-Q100 qualification system and measured data from leading manufacturers, t…
