EEPROM content erased - M24M01-RMN6P

Hi,

Currently, I am using EEPROM (p/n:M24M01-RMN6P) for data logging.The chip is operating at 3.3V and the circuit shown in the figure below.

An incident happened that the EEPROM content has been erased and when we read back the contents of the EEPROM, the values are all OxFF.

1) Any design error in the EEPROM circut?

2) What are the possible causes that the EEPROM could have been ereased?

3) under what test conditions that it will happen?

4) How to prevent the same incident happen again?

5) What is the maximum ambient temperature that an EEPROM can operate reliably at?

 

Thanks and regards,

Hi Tesla,

When no code is written, the EEPROM remains functional.The problem of deleted data cannot be reproduced.

Thanks and regards,
