Low-power LoRa SiP family for remote IoT nodes

181025 wsg pr samr34 7x5

Microchip Technology Inc., a founding member of the LoRa Alliance, has introduced a highly integrated LoRa SiP family with an ultra-low-power 32-bit 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 across hardware, software and support. Powered by the ultra-low-power SAM L21 Arm Cortex-M0+ based MCU, the SAM R34 devices also provide the industry’s lowest power consumption in sleep modes (790 nA), offering extended battery life in remote IoT nodes.

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.

Developers can accelerate their designs by combining their application code with Microchip’s LoRaWAN stack and quickly prototype with the ATSAMR34-XPRO development board (DM320111), which is supported by the Atmel Studio 7 Software Development Kit (SDK). The development board is certified by the Federal Communications Commission (FCC), Industry Canada (IC) and Radio Equipment Directive (RED), providing developers with the confidence that their designs will meet government requirements across geographies.

At the same time, with support for worldwide LoRaWAN operation from 862 to 1020 MHz, developers can use a single part variant across geographies, further 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.
