I noticed the time data crash of an RTC. What could be the possible reasons?

answer

Real Time ClockHow to use

The most probable cause is power supply (VDD) voltage drop and instantaneous power failure. Other probable causes of data crash are forcing a voltage exceeding the absolute maximum ratings and spark noise. An RTC itself never resets or overwrites time data without such causes.
