KW41 marking code issue as below the first word (9) of 2nd line is different with NXP AN5377 shown L as below pictures.
Can you help to check what is the different between “9” & “L” ?
on the AN5377 is just a sample, the L can be different number depending the part that you are using, I believe that you are using the MKW41Z512VHT4
I hope this will help you.
Could you please explain what the number mean? What does "9" mean?
And I also see the number is "L" on FRDM_KW40Z. What does "L" mean?
Is there another number?
the L is on the KW40
9 is for KW41
there are more number or letter for different MCU familys
