LoRa technology is designed to enable low-power applications to communicate over longer ranges than Zigbee®, Wi-Fi® and Bluetooth® using the LoRaWAN open protocol. Ideal for a range of applications such as smart cities, agricultural monitoring and supply-chain tracking, LoRaWAN enables the creation of flexible IoT networks that can operate in both urban and rural environments. According to the LoRa Alliance™, the number of LoRaWAN operators has doubled from 40 to 80 over the last 12 months, with more than 100 countries actively developing LoRaWAN networks.
 
The SAM R34/35 family is supported by Microchip’s LoRaWAN stack, as well as a certified and proven chip-down package that enables customers to accelerate the design of RF applications with reduced risk. With support for worldwide LoRaWAN operation from 862 to 1020 MHz, developers can use a single part variant across geographies, 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.
 
Microchip’s SAM R34/35 LoRa family is available in six device variants, providing developers the flexibility to choose the best combination of memory and peripherals for their end application. SAM R34 devices offer a 64-lead TFBGA package and the SAM R35 devices are available without a USB interface.
