Atmel Corp. has begun shipping in production quantities its SAM D20. According to the company, the first series in a family of ultra-low power embedded flash MCUs are based on the ARM Cortex-M0+ processor.<.p>

In this era of the Internet of Things (IoT), products used in building automation, consumer electronics, smart metering and industrial controls are becoming smarter and more connected. With Atmel's SAM D20 MCU available to the mass market, designers now have access to a Cortex M0+ based MCU to easily add more intelligence and connectivity to next-generation IoT devices.

The 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 SAM D20 series is 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.

Atmel's SAM D20 Cortex-M0+ ARM-based series integrates high-precision 12bit analogue and internal oscillators, up to eight 16bit timer/counters, real-time performance, peripheral event system, and flexible clocking options and sleep modes. It also features 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 family includes four to six SERCOM modules. Additonally, the device touts support for button, slider and wheel touch capability as well as proximity without the need for external components, and features 14 devices available in 32-, 48- and 64-pin package options with 16-256KB of Flash memory.

To accelerate design, the SAM D20 Xplained PRO evaluation kits are available for $39. The kit features a 64-pin and a 256KB SAM D20 device along with a programmer/debugger and hardware to evaluate both the processor and the peripherals and comes pre-loaded with software that can easily be re-programmed, debugged and prototyped.

Production quantities of the 128KB 32-pin, and 256KB 48-and 64 pin products are available in QFN and QFP packages.
