LoRa SiP Slashes Power Consumption

Accelerating development of long range (LoRa) technology, Microchip Technology introduces 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 offer interoperability with major LoRaWAN gateway and network providers. Reportedly, 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 SAM L21 Arm Cortex-M0+ based MCU, the SAM R34 devices provide sleep modes as low as 790 nA. In a 6 mm x 6 mm package, the SAM R34/35 family suits applications that require small form factor designs.

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.

 

The SAM R34/35 LoRa family is available in six versions. Price for devices in a 64-lead TFBGA package begin at $3.76 each/10,000. SAM R35 devices are available without a USB interface starting at $3.66 each/10,000. For more details, visit the product info page.
