Hey Paul,

I am starting out with Embedded "stuff" and I had a question. What's the deal with the various manfuactuers in terms of the chips? I want to design something that uses an ARM7 or above and I see that you can get the processor chip from Atmel, Philips, Samsung, etc.

What motiviates a circuit designer to use one brand over another?

Also, we would like to work in the .net MF environment. If you know of any procs that have a ported .mf framework, any insight would be appreciated. I looked at the other IDEs and don't really want to use assembly or an Embedded brand derivative of C for development. After like 8 languages, it gets crazy to go after more if you know what I mean.

Many Thanks!
Ed

Some information to consider:
ARM Holdings

"ARM Holdings is the world's leading semiconductor intellectual property (IP) supplier and as such is at the heart of the development of digital electronic products."

"The ARM business model involves the designing and licensing of IP rather than the manufacturing and selling of actual semiconductor chips. We license IP to a network of Partners, which includes the world's leading semiconductor and systems companies."

Take a look at the links below and the columns for Memory, Peripherals, & Embedded Interface. These are all features in addition to the processor core.
168 Product results found for “arm7”

Also see this Wikipedia article.
The .NET Micro Framework is currently supported on ARM architecture processors (including ARM7 and ARM9)

...With referance to my point before - engineers should be encoraged to select a chip on what they need, not bindly use a ARM or .NET just cos its sounds nice...

I think Ed is aware that ARM are a nice bunch of jolly chaps. His problem is deciding which ARM licensee (if any) to buy chips from. I think we need to know more about his application before we give too much advice.
