I am yet to see why ARM has not reached $3B in revenue and still languishing below $1B. Everyone is congregating with them and they seem to have a great product. But not making things and living on the paltry commission/royalty means they may never be big. The risk is low for them, but they are losing out.
@daleste: Another nice development system. This looks like a well thought out low power family of microcontrollers. It should do well in the market. Will industrial and automotive versions be available?
The Energy Micro stuff is really very tasty -- and, as you say, it's very well thought out. For example, if you have two identical packages from different families, they are pin-compatible -- you woudl think thsi would be obvious, but I lot of manufacturers don;t do it.
I didn't even touch on their software environment, which boasts sophisticated power-consumption analysis capabilities. For example, you can run code in a simulator and see the estimated power that will be consumed -- if you see a power spike in the waveform you can click on it to be taken to the corresponding area in the code.
Re your question about industrial and automotive versions -- I'll ask the folks from Silicon Labs to comment here.
I would love to see SI Labs combine their Energy Micro M4F chips with their SI47xx/48xx RF IC's. I have a project that would benifit from that. A single chip with these components in a QFN32/48 package, that would be nice indeed
