Hi,

I would like to ask about replacing SRAM 55ns speed grade by 45ns speed grade as I want the feature of non-volatile but the old SRAM in my board using 55ns So not sure I can replace this or not

Hi @itongx ,

The 45ns graded device can work in place of 55ns graded device as it can also operate  at a lower speed. It would have an issue the other way round but not this. 

Thanks,

Pradipta.
