Atmel Adds SAM D21, D10 and D11 MCUs to Its ARM Cortex M0+ SAM D Family

Atmel launched SAM D20 MCU family based on ARM Cortex M0+ last year, and at Embedded World 2014, the company has launched three new MCU families featuring ARM ultra low power core with SAM D10, SAM D11, and SAM D21 families and their corresponding Xplained PRO development boards. Atmel four SAM D  families target different applications and price points: SAM D10 – The smallest member of the SAM D family in terms of memory, pin count, and features. SAM D11 – Adds full-speed USB not available on the SAM D10. SAM D20 – “Offers a rich set of peripherals, flexibility, and ease-of-use with low power consumption.” SAM D21 – Adds features such as full-speed USB, DMA, high-end timers/counters to D20 design. I’ve compared the four families in the table below: SAM D10 SAM D11 SAM D20 SAM D21 # MCU in Family 4 4 15 12 MCU Core ARM Cortex-M0+ based MCU running up to 48MHz Memory 8 to 16KB …

Atmel Introduces ARM Cortex M0+ based SmartConnect Wi-Fi Modules and SmartConnect Zigbee SoCs

In order for the Internet of Things to take off, wireless connectivity solutions with ultra low power, lost cost, and small footprint are needed. Atmel seems to have made a step in the right direction by launching SmartConnect Wi-Fi modules and Zigbee SoCs featuring an ARM Cortex M0+ core. SmartConnect Wi-Fi does not appear to be a single chip solution, but instead Atmel has created a family of Wi-Fi modules integrating the company’s ultra-low power Wi-Fi SoChip with an ARM Cortex M0+ based MCU. These modules will enabled battery-powered Wi-Fi connectivity for IoT endpoints such as thermostats, and temperature sensors in a cost effective way. The company will provide a software solution with application and security protocols such as TLS, TCP/IP stack and an RTOS, all of which can be downloaded via Atmel Studio 6 Integrated Development Platform (IDP). SmartConnect ZigBee SAM R21 combines an ARM Cortex M0+ core with a Zigbee RF receiver in a single chip which will …
