Mouser ships Microchip’s SAM R34 SiPs to deliver low power LoRa for edge devices

Distributor, Mouser Electronics, is now stocking the SAM R34 LoRa sub-GHz system in package (SiP) family from Microchip Technology. The SAM R34 SiP devices are claimed to delivering industry-leading low-power performance for a range of IoT applications. The SiP family integrates a 32-bit microcontroller, software stack, and sub-GHz LoRa transceiver in a small 6.0 x 6.0mm package.

The Microchip SAM R34 LoRa sub-GHz SiPs, available from Mouser Electronics, incorporate a Microchip SAM L21 microcontroller based on a 32-bit Arm Cortex-M0+ core with up to 256kbytes of flash and 40kbytes of RAM. The onboard UHF transceiver supports LoRa and FSK modulation and covers frequencies from 137 to 1020MHz with maximum transmit power up to +20dBm without external amplification. The SAM R34 family is supported by Microchip’s LoRaWAN protocol stack and supports Class A and Class C end devices, as well as proprietary point-to-point connections.

The SiPs offer sleep modes as low as 790nA, which help to extend battery life and conserve power consumption in smart devices. The SAM R34 SiP includes a USB interface, making it suitable for USB dongle applications or for software updates via USB. The SiPs are suitable for battery-powered and sensor-based connected applications, including smart agriculture, smart city devices, and tracking devices for supply chain management.

Mouser also stocks the SAM R34 Xplained Pro evaluation kit, supported by the Atmel Studio 7 integrated development platform. The kit includes reference designs and software examples that enable engineers to develop SAM R34-based LoRa end-node applications. The kit is certified with the Federal Communications Commission (FCC), Industry Canada (IC), and Radio Equipment Directive (RED) so designs can meet government requirements across geographies.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Mouser Electronics’ website is continually updated and offers advanced search methods to help customers quickly locate inventory. also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.
