Atmel has announced a new controller family called AT91SAM3U based on the ARM Cortex-M3. If you have been following the development of the ARM market this was only a matter of time, since the big competitors NXP and TI (with its recent aquisition of Luminary) are already shipping Cortex-M3 based controllers. Unlike them however, Atmel seems to be targeting only the higher end of Cortex-M3 applications, which is also not too surprising considering their strong position in the 8 bit market with the AVR (and AVR XMEGA) family.

TI buys Luminary Micro
Texas Instruments just announced that they acquired Luminary Micro, vendor of the popular ARM Cortex M3-based Stellaris microcontroller series. A step that seems to make sense, since TI had fallen a bit behind in the general purpose, low end ARM controller market.

Articles on EmbDev.net
An article section has been added on EmbDev.net. The first articles are a general overview of ARM-based microcontrollers (cores, development tools) and my ARM MP3/AAC Player project (previously published on Mikrocontroller.net).
The articles are organized as a Wiki, that means anyone can edit and create articles. If you want to write an article about a project you would like to present or a topic that interests you, see How to create a new article.

New Luminary Stellaris microcontrollers (ARM Cortex-M3)
The new Stellaris 9000 series by Luminary is based on the ARM Cortex-M3 and offers up to 96 kB RAM and 100 MHz clock speed. New features include I2S (for audio CODECs) and an external peripheral interface that supports SDRAM and a host mode.

ARM announces Cortex-M0 processor core
ARM is intensifying its attack on the 8-bit controller market with a new ultra-low power processor core, the Cortex-M0. At claimed 0.85 µW/MHz the power efficiency is comparable to controllers of the AVR or MSP430 families. The Cortex-M0 implements the Thumb-1 and a subset of the Thumb-2 instruction set, so the same level of support by open source tools can be expected as for the other ARM cores.
NXP, best known for its ARM7-based controller family LPC2000, has announced to become the first licensee for the Cortex-M0, though no specific products have been announced yet.
