    "How to program EPROM W25R128JWSIQ"

    Hello, a pleasure to join the community!

    I have tried to program this EPROM from a laptop, the W25R128JWSIQ.

    I tried using the CH341A, but it does not have support for this chip. Is there any programmer that can detect it so I can burn the bin file?

    it's a 1.8v chip.
    CH341 only handles 3.3v
    so you could use a 1.8v adapter in the 341 if you can find that chip in alternate software.
    take a look here:

      I know, I use it with the 1.8v adapter But he. Ch341 does not have that memory in its database, which is not compatible

          In the link you shared, there is nothing.
          That's why I posted here to see if anyone knows a programmer for that EEPROM or if someone has managed to program it.

              Sure!

              "Exactly, I already tried those programs, but none of them support that EEPROM. Which seems strange to me, since it's a Lenovo laptop with a Ryzen 5."

                  Don`t use Auto-detect, choose a different chip manually such as W25Q128FW. If should read ok. You won`t be able to use verify when writing.
