Hi Irmantas Budrys,
KE is the 5V, Robust Microcontrollers (MCUs) based on ARM, it mainly used in the industry area. It is designed to maintain high-reliability and robustness in harsh electrical noise environments targeting white goods and industrial applications.
KEA is also 5V, Ultra-Reliable KEA Automotive Microcontrollers, it is targeted for a wide range of automotive and industrial applications requiring the highest level of quality and longevity support.
KEA have more wide temperature range, to meet the automotive demand. It also add some other module's like PWT which is not in the KE series.
But the communication interface is nearlly the same, so you can refer to the KE series.
There still don't have any manuals to migrate from KE to KEA, you can use the KEA project, and just add the according module code to the KEA. Then take care of the clock.
Wish it helps you!
Have a great day,
Kerry
