Hello,

I'm a software expert, and ignorant in any hardware fields.

I have some faulty air condition controller board, and need help with identifying some faulty component installed on it.

Could you please tell me what is this EEPROM component (see picture), and what component could be used to replace it, preferably of FRAM type?

Thanks,

Mark

    ​Hello,

    This is a very old (>20years) serial I2C eeprom in 4Kbits density.

    Direct replacement is possible with ST eeprom device: See here : https://www.st.com/content/st_com/en/products/memories/serial-eeprom/standard-serial-eeprom/standard-i2c-eeprom/m24c04-f.html

    For you information our eeproms are guarantied 4millions cycles @25°C if you search a very high level of endurance.

    You need to check for yourself.

    At the image, there is not much visible around this chip to see if this makes sense.
