M24512-A125 EEPROM memory address write cycles

Hello,

I am a developer making a product that controls the M24512-A125 EEPROM with I2C.

I am positive about the M24512-A125 product.

I have a question while developing.

I know there is a limit to the write cycles.

Please let me know if my analysis is correct.

In the figure below, I made a Memory Map as I thought.

I understood that at a temperature of 125℃, one memory address can write 600,000 write cycles.

Is that correct?

I look forward to your reply.

Welcome, @Skim.3​, to the community!

Yes, the number of write cycles in EEPROMs refers to each individual byte groups of four bytes, i.e. each individual address. You will find additional information in the datasheet, section 5.2, AN4434 and in AN2440.

If the problem is resolved, please mark this topic as answered by selecting Select as best. This will help other users find that answer faster.

Good luck!

[edit]Sorry for the mistake: the endurance of the M24512 refers to 4 bytes, not 1 byte as originally written.[/edit]
