Dears :

     I want to select a Pin to Pin replacement P/N of FM24CL64B-GTR

     It seems CY15E064J-SXA is the best choice

     looking from description in part number searching website, the operation voltage  is 3V-3.6V

     but in the description of datasheet, it 's 4.5V-5.5V

please help comfirm which is the exact VDD parameters, can CY15E064J-SXA be P2P compatiable to FM24CL64B-GTR ?

thanks

A. No, because the VDD operating range is different.

Ritwick：

    Thanks for your confirmation

     It's a machinery controller application, industrial temperature（-40 - +85） is enough

     what's your recommendation for this replacment requirement ?
