However, the datasheet and TRM only mention the processor core.
Hello, I read it as a CPU that obeys the Armv7-M architecture, without going into any further detail.
Similarly you can see this (for example) for the Cortex-M4, and the Cortex-M33 shows Armv8-M mainline architecture.

I know, but it doesn't show "Armv7-M processor core". It started to confuse me. I hope it will be more standardized when to avoid ambiguity.Anyway, thank you for your answer.
