Content for AT86RF215


The AT86RF215 is a multi-band radio transceiver for various sub-1GHz bands and the 2.4GHz band specially designed for smart metering and applications implementing IEEE Std 802.15.4g™-2012, ETSI TS 102 887-1, IEEE Std 802.15.4TM-2015. The device is comprised of two independent transceivers, each with its own baseband and I/Q data interface. The AT86RF215 incorporates two transceivers and two baseband cores forming two independent radio systems. The transceivers are highly integrated minimizing the number of external components required on the printed circuit board (PCB). The supply voltage ranges from 1.8V to 3.6V. A 26MHz temperature controlled oscillator (TCXO) or a crystal oscillator (XTAL) is used as a reference clock. The AT86RF215 allows simultaneous independent reception in the sub-1GHz and 2.4GHz bands. Each radio frequency (RF) port is accessed with balanced differential signal pairs. Optimal sensitivity and output power are achieved with 50Ω differential load. The device offers a high link budget with maximum TX output power of 14.5dBm@900MHz and sensitivity down to -123dBm@MR-OQPSK-6.25kb/s. The device is controlled via a fast serial peripheral interface (SPI). Dedicated MAC hardware, random number generator and on-board battery monitoring improve overall system efficiency and timing. The AT86RF215 can be operated with an external microcontroller (e.g. Atmel SAM4 Family) and/or an external baseband processor.
