LoRa® (Long Range) technology is extending the reach of the Internet of Things (IoT) by combining long-range wireless connectivity with low-power performance. To accelerate the development of LoRa-based connected solutions, Microchip introduced a highly integrated LoRa System-in-Package (SiP) family with an ultra-low-power 32-bit microcontroller (MCU), sub-GHz RF LoRa transceiver and software stack. The SAM R34/35 SiPs come with 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 up 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 790 nA to significantly reduce power consumption and extend battery life in end applications. Highly integrated in a compact 6 x 6 mm package, the SAM R34/35 family is ideal for a broad array of long-range, low-power IoT applications that require small form factor designs and multiple years of battery life.
