How do you choose an ARM family

How do I go about picking an architecture ? My first thoughts suggested Cortex M3 but the more I look into it the less sure I am.

Obviously I don't to go to the trouble of learning a new technology only to find that I've made a bad processor choice (ie nearly end of line). I've spent many hours looking at many websites and have yet to find any high-level stuff on choosing my first ARM device.

If there's one thing wrong with ARM its the almost infinite number of devices

I'm an embedded developer wanting to undertake my first ARM project, so I'm completely new to the ARM architecture. I want a low power device with serial, USB and some ADC channels.

  • The Cortex M3 is supposed to be an "easy (easier?) to use" ARM - so I guess that would be the one to start with?

    Being quite new, the manufacturers & distributors are pushing it quite hard - so you should be able to find some introductory seminars/workshops (probably free) without too much trouble...

    Personally, I would recommend a Luminary Micro (now TI) kit to start with: they are cheap, and you get a complete, ready-to-go kit - including tools - all in the box.
