The SAM D20 from Atmel Corporation is the first series in a new family of embedded Flash microcontrollers based on the ARM Cortex-M0+ processor core. The new MCUs are targeted for home automation, consumer, smart metering and industrial applications. The new series combines intelligent peripherals with Atmel’s Event System and capacitive touch support for button, slider and wheel capability and proximity sensing.
The SAM D20 Cortex-M0+ ARM-based series integrates 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.
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.
