Microchip Technology introduced 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 to accelerate the development of LoRa-based connected products. The SAM R34/35 SiPs come with 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 company said its 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 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 suited 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). 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.
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 in a 64-lead TFBGA package begin at USD 3.76 each in 10,000-unit quantities. SAM R35 devices are available without a USB interface starting at USD 3.66 each in 10,000-unit quantities.
