Hi,

any help or information to find the data sheet and to determine an available replacement type for an obsolete EEPROM chip from ST marked 950406 would be highly appreciated.

A picture of the chip is attached.

The defective EEPROM chip 950406 comes from a Landis & Staefa heating controller, year of manufacture of the controller was +- 2002.

Thanks in advance and best regards.

    @Tom6 You could try the M95040-RMN6TP or the M95040-FMN6TP. The ST950406 can only be operated with 5V, but the alternatives can be operated from 1.7V or 1.8V up to and including 5V.

    Hope that helps?

    Good luck!
