Do you know how to write an EEPROM? If you can both .. you're done. If there is a NO, then tell us why? All you need to do is written in the datasheet. What item of the datasheet did you not understand? Klaus Upvote 0 Downvote

Please indicate me the hardware that I can use or a datasheet where I can read from. This EEPROM is used as a count down counter in a machine. Thanks, Bruno Upvote 0 Downvote

They are typically using protection features to block unauthorized editing. ds1977-f5 datasheet is available on the internet. https://www.analog.com/media/en/technical-documentation/data-sheets/DS1977.pdf Upvote 0 Downvote
