Key Facts:
  • Industry-leading low power consumption from SAM R34/35 LoRa System-in-Package (SiP)
  • Enables long-range wireless connectivity and extended system battery life in remote IoT
  • Interoperable with major LoRaWAN™ gateway and network providers
  • Development board certified with FCC, Industry Canada and Radio Equipment Directive
 
Microchip announces 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 combination of long-range wireless connectivity with low-power performance is designed to accelerate the development of LoRa-based connected solutions.
 
The SAM R34/35 SiPs 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 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.
 
In addition to ultra-low-power consumption, the simplified development process means 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 with 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.
