M0 is 32-bits, 16 x 2 = 32 M4 is 32-bits, 586 x 2 = 1,272 works for me ;-)

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

"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

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