    Hello!
    I need to read and write from memory 24LC1025-I / SM from Microchip, I will be doing it for the first time and I need tips from more experienced colleagues on how to carry out this operation, starting with choosing an inexpensive programmer and a memory socket. Memory acc. the data sheet has WP on pin 7, i.e. write protection, and if I understand correctly, when the voltage reaches it, it blocks the writing. I will be very grateful for any tips on how to do it and whether it can be done at all. I will not disdain a tutorial for programming these memories, if there is one :) .

    best regards

    You can buy a cheap programmer from the CH341 series for 20 with shipping, or you can make it yourself according to one of the schemes posted on the web or on the forum.

    Tutorial - well, it is different for each program. It depends on what programmer you will have.

    Thank you for your answer! I have one more question, the programmer application does not find my memory, it should be called MIC24LC1025, the closest one is MIC24LC1024 also 128 bit. Will it ensure correct data recording? The application written by SkyGz Series Soft, has its own database in .dat, but I don't know what I could edit it to check what memory parameters are taken into account, because if only the capacity and number of pins, it should be ok.

    Have you tried to program it as any 241024?

    I am still waiting for this programmer, the thing is that I prefer to get acquainted with the soft before and dispel any doubts, because I have no possibility to make a mistake, to put it mildly, because it would cost me too much. I wrote to the creator of the program and wrote back to boldly program as mic24aa1024. Thanks Freddy for help, problem solved :)

    (until I save it, I leave the thread open)

    Have you already bought or are you going to buy a programmer?

    I bought it on the Allegro, tomorrow it will come + SOC8 clip so that I do not have to desolder the memory from the system

    OK, then if you do, let me know about the effects - for others.

Topic summary

The discussion revolves around programming the 24LC1025-I/SM EEPROM from Microchip. A user seeks advice on selecting an inexpensive programmer and memory socket for their first programming attempt. Recommendations include using a CH341 series programmer or building one from available schematics. The user encounters issues with the programmer application not recognizing the memory, initially trying to use the MIC24LC1024 as a substitute. After consulting with the software creator, they are advised to program it as MIC24AA1024. The user also mentions purchasing a SOC8 clip to avoid desoldering the memory from the system, indicating a preference for careful handling to prevent costly mistakes.
