对于所有物联网 (IoT) 设计，现在，可以在一流的 2.4 GHz 射频收发器中选用基于 ARM® Cortex®-M0+ 的 32 位微控制器或选用 8 位 AVR 内核微控制器。SAM R21 系列像其先前的产品（ATmegaxxxRFR2 和 ATmegaxxxRFA1）一样，是符合 IEEE 802.15.4 标准的单芯片无线解决方案，它超越了惯有的所有优点和功能，具有如下改进：
所有这些改进的优点都基于 8 位 AVR 无线微控制器所打造的坚实基础，多年来 8 位 AVR 无线微控制器应用广泛，可提供如下功能：
最后但同样重要的是，借助免费的 Atmel 软件栈、无线编辑器、库以及硬件评估和开发工具包，系统开发依然非常容易。
