Can S9S12XS256J0CAE completely replace S9S12XS128J1CAE? Are the two just the difference in flash size?

If I don't have this S9S12XS128J1CAE, can I use S9S12XS256J0CAE instead?

Hello @Awing,

Not only the Flash size but the SRAM too:

There are a few different specifications,

Table A-5. Thermal Package Characteristics (9S12XS256)

Table A-6. Thermal Package Characteristics (9S12XS128)

Table A-12. Run and Wait Current Characteristics

 

These two parts have different masks:

S9S12XS256J0CAE 0M05M

S9S12XS128J1CAE 1M04M

The RM specifies different part ID numbers:

Each mask revision has a different errata document:
