We are in the process of selecting a micro for a new project and are looking at SAM4 and SAM7 series parts.  I have read some info that makes me think that the M7 has a newer and maybe better debug infrastructure.  Has anyone here used both and is there a significant difference that we should take into consideration in our selection process?

 

Thanks

hello

SAM7 (ARM/) parts are a good choice but already up to 10 years old.

So if there is no absolute reason for using SAM7 it would be the better choice in any point of view to use a SAM with Cortex M.

"SAM7" are ARM7 parts:

as gerhardf says, this is a "legacy" architecture.

Are you thinking of Cortex-M7 ?

That is an entirely newer and "better" architecture all around (or so they'd have us believe)
