Trying to learn about the ARM Cortex M3 solution for low cost embedded market. Their web site isn't much more than a shallow advertisement. http://www.arm.com/products/CPUs/ARM_Cortex-M3.html The "datasheet" is a two sheet sales flyer. No mention of who is licensing and selling this core in chip form. I need some help. Anybody know who has implemented the ARM Cortex M3 core in a chip available to the masses?
ARM Cortex M3 - Who's utilizing it?

It's the next generation ARM wave, and it will take a little while to see devices built around it. Same thing for the other variants (the A8 and future R derivatives). Ulf, we're waiting for the ARM Cortex vs AVR32 battle. :)

Test sillicon is available, and if you understand some Russian, you can become an alpha tester (http://supplier.ru/rus/news/?action=show&id=7). The first M3 development tools will be available in a few weeks. More Thumb-2 and v7-M architecture info should become public soon. Wilco

While the Cortex is probably an improvement over ARM, it may not be improvement enough to motivate people to pay millions of dollars. Think most semiconductor companies will adopt a wait and see. If needed, it can be licensed and introduced quickly. If not needed, noone will bother... One of the arguments for an ARM, is the second source. The first company to release a Cortex will not have a second source... It will compete with the coldfires, SH series etc.> Ulf, we're waiting for the ARM Cortex vs AVR32 battle. :)Doesn't look like there are Semiconductor companies in the official Cortex M3 list of licensees... T.I has licensed the Cortex-A8, but I think this is for Nokia and alike... The AVR32 seems to run at higher frequency and has an MMU so they may be focusing on different markets. -- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This message is intended to be my own personal view and it may or may not be shared by my employer Atmel Nordic AB

The M3 was announced two years ago in 2004. Why isn't it in production yet? Curious.

I did wonder if Luminary Micro was going to use the Cortex Core. Since they are a brand new startup, it would seem most of the established ARM microcontroller vendors did NOT rush to embrace the Cortex M3. Hmmmm. According to the press, they will start the hoopla on March 6th. http://www.eet.com/news/semi/showArticle.jhtml?articleID=180203864 [Just remember, hoopla can preceed full commercial release by 12+ months] Still, a green core, plus a green startup, combined has more risks than many will tolerate. Be worth watching... 8-64KF, and 2-6KRam is now crowded space, they will need something in the peripherals to get attention. -jg

Looks like the only visible starter for M3, is a very green, startup company. - This is their first product...> T.I has licensed the Cortex-A8, but I think this is for Nokia and alike... > The AVR32 seems to run at higher frequency and has an MMU > so they may be focusing on different markets.I'd agree - if you look at the little that is mentioned on the upcomming devices, they mention 8-64K Flash, and 2-6K Ram - which is crowded space right now, and even somewhat outside the 32 bit sweetspot. ie : You don't really want to pitch where users are now, but where they WILL be on their next design. So the key to how well this goes, will NOT be the core, but the SW tools, the periherals, and if they have managed to run faster than most FLASH... -jg

It is an ARM11 + Jazelle + Thumb-2 clone, but because it is late (MIPS did it a few years ago), it now will have to compete with Cortex-A8. Ouch... Wilco
