Hi everyone!

This is my first post here :)
I'm interested in making a platform which has an 32-bit MCU as the centralcomponent. This platform is supposed to be configurable, i.e. do thingsthat an 8-bit MCU can handle OR do more advanced signal processing. What I have come up with is ARM Cortex M.
From what I've read on theinternet is that NXP has pin- & software-compatible devices in Cortex M0, M3 and M4. In addition, STMicroelectronics will have the same this year, theycurrently only have Cortex M3 and M4.

I would like to hear some reviews from you guys on the NXP and ST devices. What would you recommend if you don't want to recommend these, Renesas, Microchip etc. I am open to all suggestions. I don't have special criterias at this point, not more than low cost and low power consumption. But those are almost always criterias, I guess.

Really appreciate any input!!
