Hello arimendes,
Yes, IAR is always a good source of new not jet announced controllers. But I don’t think you will get some public statement to this controller up to now.
However, you can simply compare the Header Files of the two Controller (1021 vs. 1024) which you have found in IAR installation folder to get the differences.
Best Regards
