MCU Wireless chipset for IEEE 802.15.4 and ZigBee® applications. It is a bundle of the Atmel AVR ATmega2561 and Atmel AT86RF212 radio for the regional 700/800/900MHz frequency bands.
The AT86RF212 is a low-power, low-voltage 700/800/900 MHz transceiver designed for low-cost IEEE 802.15.4, ZigBee, 6LoWPAN and high data rate ISM applications. available in China, Europe and North America. It is a true SPI-to-antenna solution providing a complete radio transceiver interface between the antenna and the microcontroller. All RF-critical components are integrated on a single chip minimizing the number of required external components to the antenna, crystal and decoupling capacitors.
