Description
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
[3],
ETSI TS 102 887-1
[5],
IEEE Std
802.15.4
TM
-2015
[7].
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.

Block Diagram
The device features two independent radio systems. It contains one sub-1GHz transceiver and one 2.4GHz transceiver.
Each transceiver is paired with a baseband core optimized to demodulate signals commonly used in the associated
band, thus providing complete RF-to-Baseband operation. The internal baseband cores support MR-FSK, O-QPSK/MR-
O-QPSK and MR-OFDM modulation schemes. Alternatively users can route the I/Q data stream directly to an external
processor for advanced signal processing using the 13-bit LVDS interface.
The AT86RF215 block diagram is shown in Figure 1-1.
