Hello Kinetis friends!
The launch of new Kinetis devices and development tools called "Kinetis K2" brought some new K22_120 MHz devices to the K22 family portfolio.
:smileyinfo: Please notice the name "Kinetis K2" only refers to the Kinetis generation, but it is not related to part number (e.g. K63/K64 are part of K2 generation).
Previously existing Kinetis portfolio already had some K22_120 MHz devices, so this caused confusion regarding the documentation, header files, features, development boards and others, because the part numbers are very similar.
I created the next reference table outlining the existing K22_120 MHz parts with their corresponding files and boards. The last column is an overview of the features or peripherals that are either missing or added in each device.
:smileyalert: IMPORTANT NOTES:
- I gathered and put together this information as reference, but it is not official. For the most accurate information please visit our webpage www.nxp.com.
- Header files MK22F12.h and MK22FA12.h apply for legacy K22_120 devices. However TWR-K21F120M(A) board has a K21_120 part, so use MK21F12.h or MK21FA12.h instead.
Colleague Carlos Chavez released an Engineering Bulletin (EB811) with good information related to this document:
