The devices are supported by certified reference designs and proven interoperability with major LoRaWAN gateway and network providers, significantly simplifying the entire development process with hardware, software and support. The devices also provide the industry’s lowest power consumption in sleep modes, offering extended battery life in remote IoT nodes.
Most LoRa end devices remain in sleep mode for extended periods of time, only waking occasionally to transmit small data packets. Powered by the ultra-low-power SAM L21 Arm Cortex-M0+ based MCU, the SAM R34 devices provide sleep modes as low as 790nA to significantly reduce power consumption and extend battery life in end applications. Highly integrated in a compact 6x6mm package, the SAM R34/35 family fits a broad array of long-range, low-power IoT applications that require small form factor designs and multiple years of battery life.
With support for worldwide LoRaWAN operation from 862 to 1020 MHz, developers can use a single part variant across geographies, simplifying the design process and reducing inventory burden. The SAM R34/35 family supports Class A and Class C end devices as well as proprietary point-to-point connections.
Microchip’s SAM R34/35 LoRa family is available in six device variants with different combinations of memory and peripherals. SAM R34 devices offer a 64-lead TFBGA package and the SAM R35 devices are available without a USB interface.
