We are having issues buying the MKL15Z128VFM4 part from distributors as they are out of stock. The MKL16Z128VFM4 and MKL17Z128VFM4 parts are, however, available (the first may be bought directly from NXP buy-direct).
I already know the parts are compatible, but I am not sure on what level!
As I may update some existent devices directly in field, I don't want to manage multiple firmware versions - so having the same firmware for both parts is desired.
The main question is: may I program the same firmware (I mean, the same .srec/hex file) I used on MKL15 based devices on the MKL16 new ones? Or do I need to generate a new one and manage two versions of the firmware?
Important: I'm not using i2s in my design (I've already seen this is a new feature on MKL16)
Thank you very much! I appreciate your help as our product is almost on back order!
