Atmel Corporation has announced its new SAM D20 microcontrollers – the first series in a new family of embedded Flash microcontrollers based on the ARM Cortex-M0+ processor core and designed for home automation, consumer, smart metering, and industrial applications.
Leveraging two decades of microcontroller experience and success with the company’s easy-to-use AVR- and ARM-based products, the new series combines innovative and proven technologies, including intelligent peripherals with Atmel’s Event System and capacitive touch support for button, slider and wheel capability and proximity sensing. The new SAM D20 series is also supported by the latest version of Atmel Studio and Atmel Software Framework, the integrated development platform for developing and debugging Atmel ARM Cortex-M and Atmel AVR MCU- based applications.

Bosch Sensortec GmbH is among the first adopters of the new Atmel SAM D20 device. “Customers for our next-generation self-contained 9-axis absolute orientation sensor (BNO055) will benefit from the same high performance with lower power consumption. Atmel’s SAM D20 device optimizes Bosch Sensortec’s sensor fusion software at a level that was not previously possible,” said Dr. Stefan Finkbeiner, CEO and General Manager, Bosch Sensortec GmbH, a global provider of micro-mechanical sensors for the consumer electronics market.
“Atmel’s global leadership in MCUs and its partnership with ARM has enabled the company to launch its Cortex-M0+ ARM-based family,” said Reza Kazerounian, Sr. Vice President and General Manager, Microcontroller Business Unit, Atmel Corporation. “In this era of the Internet of Things, MCUs, such as the SAM D20, are at the heart of every smart, connected device. Our SAM D20 family adds to our broad MCU portfolio, ranging from our industry-leading 8-bit AVR MCUs to our high-end Cortex-A5 MPUs. All our MCUs include unique peripheral sets, ultra-low power consumption, a complete integrated development platform, and easy-to-use development kits so designers can bring their products quickly to market.”
Key features of the Atmel SAM D20 series Atmel’s SAM D20 Cortex-M0+ ARM-based series integrates several popular features, including high-precision 12-bit analog and internal oscillators, up to eight 16-bit timer/counters, real-time performance, peripheral event system, and flexible clocking options and sleep modes.
The new devices also include a serial communication module (SERCOM module) that can be configured from the application to act as an USART, UART, SPI and I2C; each device in this new family includes four to six SERCOM modules. The new devices are also designed for a simple and intuitive migration between devices with identical peripheral modules, hex compatible code, pin compatible migration paths, and a linear address map.
The family supports button, slider and wheel touch capability as well as proximity without the need for external components, and features 14 new devices available in 32-, 48- and 64-pin package options with 16 to 256KB of Flash memory.
Evaluation kit To accelerate design, the SAM D20 Xplained PRO evaluation kits are available today for USD $39. The kit features a 64-pin, 256KB SAM D20 device along with a programmer/debugger and hardware to evaluate both the processor and the peripherals. The Xplained PRO kit also comes pre-loaded with software that can easily be re-programmed, debugged and prototyped without any additional tools. To purchase a kit, visit the Atmel Store.
Pricing and availability Atmel is working with alpha customers that will go into volume production shortly. Samples of 128KB 32-pin, and 256KB 48-and 64 pin products are available in QFN and QFP packages now. Pricing starts at $1.02 USD for 1K units of the 16KB 32-pin QFN package.

The question for me who is better? Full comparison need to be run, and see where each of them have better and not performance. Everyone try to sell but without highlight the pros comparing to the available product on the market is not mean to much for me. It is mean spending of time to compare one new thing. While if the company want to really attract me fast they should directly point where are 100% better there there and there.
I really like the way that Atmel have merged the best features from the AVR and ARM families to generate this new offering. Of course they already have MCUs based on Cortex-M3 and -M4 processors (and higher), but these new Cortex-M0+ parts fill a real need with regard to miniscule power consumption required by the Internet of Things.
I particularly like their Event system, which allows peripheral to do things autonomously without waking the MCU unless it's necessary -- such as an A/D converter that periodically takes a reading but only wakes the MCU if the value falls inside (or outside) specified bounds...
