November 13, 2018 — Microchip Technology introduced a LoRa System-in-Package (SiP) family with a 32-bit microcontroller (MCU), sub-GHz RF LoRa transceiver and software stack. The SAM R34/35 SiPs come with certified reference designs and interoperability with LoRaWAN gateway and network providers.
Powered by the SAM L21 Arm Cortex-M0+ based MCU, the SAM R34 devices provide sleep modes as low as 790 nA to reduce power consumption in end applications. Integrated in a 6 x 6 mm package, the SAM R34/35 family is designed for a broad array of IoT applications.
Developers can combine their application code with Microchip’s LoRaWAN stack and 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 chip-down package that enables customers to design RF applications. 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.
