I am preparing a summary chart of most of the ARM MCUs. This is a larger task than I would like. If anyone would like to assist, visit the web site at
Or if you would like, pick one of the other vendors and fill in the data. TI would not be too hard since they only have about 8 or so chips. The Atmel devices should not be a hard job since I only want to list the SAM7 parts, maybe the SAM9 as well. OKI may be hard to pull all the data together from their web page and data sheets, but they don't have a lot of parts either. I don't know much about the ST Micro parts, but they seem to have as many as the Atmel SAM7 or TI I believe.
I hope these data can be useful to others. I figured if I were going to do it for myself I would share it. It seems wasteful to have everyone duplicate studies like this.
I guess to avoid duplication you should post here before starting any of the empty sections. No point in doing something that someone else may be doing as well.
