    Hello,

    When writing in the EEPROM you must wait until the internal process of writing finished before writing again. You have 2 manners to do it.

    First one, you wait for a delay of tw (defined in the Table 122 of the datasheet) before writing again, but this delay is the maximum time for writing.

    Or Second One, if you don't want to wait that long, you can minimize system delays by polling on ACK. This procedure is described in the datasheet of the M24LR chapter 5.10.

    I hope this can be helpful,

    Have a nice day.
