The Arm Cortex-M family now has five processors. In this paper, we compare the features of various Cortex-M processors and highlight considerations for selecting the correct processor for your application. The paper includes detailed comparisons of the Cortex-M instruction sets and advanced interrupt capabilities, along with system-level features, debug and trace features, and performance comparisons.
Since writing this block we have announced further additions to the Cortex family, Cortex-M23 and Cortex-M33, and updated the document. The latest version is available here: Cortex-M for Beginners - An overview of the Arm Cortex-M processor family and comparison (2017).
Arm Cortex-M23 and Cortex-M33 are the first embedded processors using the Armv8-M architecture, bringing the proven secure foundation of Arm TrustZone to the most constrained IoT nodes.

Thanks for sharing this! Can I use some pictures from this in my thesis using the appropriate quotes? Thanks again, i love the way you explain this things and your Defuibnitive Guide to Cortex M3/M4 is hlping me a lot.
