The customers can choose operation for Chinese WPAN band from 779 to 787 MHz, European SRD band from 863 to 870 MHz, and North American ISM band from 902 to 928 MHz. Direct sequence spread spectrum techniques support different modulation and data rates: BPSK with 20 and 40 kbit/s, compliant to IEEE 802.15.4-2006, O-QPSK with 100 and 250 kbit/s, compliant to IEEE 802.15.4-2006, and O-QPSK with 250 kbit/s, compliant to IEEE P802.15.4c (Chinese band). There is also an option to select a set of proprietary high speed modes: O-QPSK with 200, 400, 500, and 1000 kbit/s PSDU data rate.
With the receiver sensitivity up to -110 dBm and programmable transmit output power up to +10 dBm, AT86RF212 provides best link budget of 120 dB.
The new AT86RF212 provides low power consumption. Sleep currents are down to 0.2 uA, while the active power consumptions are 9 mA in receive and 18 mA in transmit mode (at 5 dBm output power). Security is supported by the on-chip AES hardware acceleration.
The AT86RF212 represents an extremely flexible wireless platform where customers can select regional support for China, Europe, and US all in one device. Data rates from 20 kbit/s up to 1000 kbit/s ensure maximum flexibility on the application side, stated Magnus Pedersen, Atmel’s product marketing director Wireless Solutions. AT86RF212 is a perfect match for AVR(R) picoPower(TM) microcontrollers when designing wireless solutions with ultra low power consumption and years of battery lifetime in mind. With the release of our new device our Chinese customers can enjoy the benefits of Sub-GHz IEEE 802.15.4 compliant technology in their region, he added.
The microcontroller wireless technology roadmap also incorporates firmware support for AVR XMEGATM, AVR32, and ARM family of microcontrollers.
