We have been using the ON Semiconductor parts and have found them to be
100% compatable with the Atmel part. We have not tested the Microchip
version so have no input for you on that.
> I use the BX35 and I need a replacement AT25256 or AT25256A memory module.
> Atmel does not recommend either one of these chips in new designs. Most
> suppliers do not carry any stock anymore. I need the DIP form factor.
> I have tested the ON Semiconductor CAT25256LI-G and it seems to work well
> without any modifications to my circuit design. Also the Microchip
> 25AA256-I/P seems to be compatible but I have not tested it.
> Does anyone here know if there are any issues with these chips? Is there a
> part that NetMedia recommends?
