difference between FN et FX for kinetis K66, difference K26 and 66

[PO220]

Hi

In the datasheet, the only difference I see between FN et FX for K66 kinetis is the size of the flash memory (2MB vs 1.25MB). am I right ?

Is the presence/absence of ethernet periphera the only difference between K66 and k26?

Thank you in advance for your confirmation

Hi PO220,

hope you are doing great.

You have some differences, some versions (this depends on the part number) have tamper detection,support IEEE standard like mac(1588) or timer(1588), what you are asking about the FN and FX the difference here is that the FN is flash memory and the parts with FX have flex memory (FTFE configuration that supports data flash, EEPROM, and FlexRAM).

hope this works, have a great day !!
