Atmel has entered the Cortex-M0+ microcontroller arena. These look like the highest performance ARM Cortex-M0+ microcontrollers.

Atmel boasts 8-bit simplicity with 16-bit performance.

Article shows a family overview and a useful block diagram.

Really, 586 page data sheet is 'simplicity' and they only think a M0 is 16-bit performance ?

LOL, the M4 family has over 1,000 pages !! M0 is 32-bits, 16 x 2 = 32 M4 is 32-bits, 586 x 2 = 1,272 works for me ;-)

Not very far from truth: The SAM4 data sheet (Cortex M4) is 1111 pages. -- -Tauno

That phrase does not appear in Atmel's press release, nor in the introductory article published on Atmel's website. And just for comparison, the ATmega168PA series datasheet is 660 pages, so the D20 is provably some 11% simpler. As a side note, I like the new look of Atmel's datasheets. There's colour, more diagrams and a more relaxed layout. It doesn't feel like a scanned-in paper anymore. -a

Seems the OP made his own spin, in that rather mangled claim then ?

I think he was just paraphrasing the article... "According to Atmel this is makes the SAMD20 the highest performing Cortex-M0+ to date." microcontroller.com is in the business of getting people to read their stuff, a bit of sensationalism helps in that department and makes the advertisers happy. -- Rick

I received the following link in a Google alert yesterday: http://www.atmel.com/Images/Atmel-42138-Getting-Started-with-FreeRTOS-on-SAM-D20_Application-Note_AT03664.pdf It looks like they have done a very nice job on this :o) [although I have not had a chance to try it yet as I'm busy on releasing support for Cortex-A9 today - I will get onto it right afterwards] Regards, Richard. + http://www.FreeRTOS.org Designed for microcontrollers.

And just for
The phrase was in Atmel's promotional material. I have removed the phrase from the article.
