Atmel Corp. has pushed out the door the first series in a family of embedded Flash MCUs based on the ARM Cortex-M0+ processor core. Aimed at home automation, consumer, smart metering and industrial applications, the Atmel SAM D20 claims to combine 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 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., noted the company. Bosch Sensortec GmbH is among the first adopters of the Atmel SAM D20 device.

The 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 family includes four to six SERCOM modules. The 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 devices available in 32-, 48- and 64-pin package options with 16 to 256KB of Flash memory.

To accelerate design, the SAM D20 Xplained PRO evaluation kits are available for Rs.2,119.57 ($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.

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. Pricing starts at Rs.55.43 ($1.02) for 1K units of the 16KB 32-pin QFN package.
