Microchip Technology has introduced a highly integrated LoRa System-in-Package (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 interoperability with major LoRaWAN gateway and network providers. The devices also provide the ultra-low power consumption in sleep modes, offering extended battery life in remote IoT nodes.
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 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 1,020 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. SAM R34 devices in a 64-lead TFBGA package begin at $3.76 each in 10,000-unit quantities. SAM R35 devices are available without a USB interface starting at $3.66 each in 10,000-unit quantities.
