Low-power LoRa System-in-Package family
Microchip 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 are supported by certified reference designs and proven interoperability with major LoRaWAN gateway and network providers, simplifying the entire development process with hardware, software and support. The devices also provide the industry’s lowest power consumption in sleep modes, offering extended battery life in remote IoT nodes.

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 reduce power consumption and extend battery life. Highly integrated in a compact 6 x 6 mm package, the SAM R34/35 family is ideal for a broad array of long-range, low-power IoT applications that require small form factor designs and multiple years of battery life.

The simplified development process allows developers to combine 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. 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.
