Do you have any active parts that would work as a direct drop-in replacement for the S25FL032P-0XMFI011 (32-Mb NOR FLASH memory)?  Using a chip with a larger memory capacity is not a problem, so long as it has the same pinout, same power/voltage range, same command and instruction structure, etc.

Also, would your S25FL127SABMFI100 (128Mb NOR FLASH memory) work as a drop-in replacement?

More broadly, is there a quick and easy way to know if one chip is compatible with another as a drop-in replacement?  I understand we might not want to replace a 128Mb chip with a 64Mb chip, but how can I determine if a chip of a larger size would work as a drop-in replacement for a chip of a lower size?

Any assistance or insight you can offer will be *most* appreciated.

TIA

Hi Richard,

S25FL127SABMFI100 is in production and can be used as a replacement for S25FL032P-0XMFI011.

Please note that the packing type for S25FL127SABMFI100 will be tray, where as packing for S25FL032P-0XMFI011 is tube.

In order to check if one part is a drop in replacement for some other part the main things that should be kept in mind are -

1. Package type of the chips should be same

2. Physical Dimensions should be compared

3. Instruction set should be compatible

4. Temperature and power ratings should be same

AWESOME, thank you!

But how can I know if the instruction set is fully compatible?

Thank you!

Hi Richard,

The only way of checking if the instruction set is fully compatible is to compare the data sheets of the two devices.

You could check the compatibility only for the set of commands being used in your application, instead of checking all the available commands.
