How do I determine in code which micro is being used

[larrydemuth]

With the disaster with getting NXP (and others) micros, I'm looking into switching to one that is available. But in my code I need to be able to tell which one I'm using. 

Is there a register or set of registers that would tell me if I'm using a MK66FN2M, or other micro?

Thats what I was looking for! Thanks!

Hi larrydemuth,

You can check the value of System Device Identification Register (SIM_SDID).

Best Regards,
