LoRa SiP Devices Provide Low Power IoT Node Solution

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.

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 mm x 6 mm package, the SAM R34/35 family is well 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), providing developers with the confidence that their designs will meet government requirements across geographies.
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 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.

Cypress and Semtech Team up on Integrated LoRaWAN Solution

Cypress Semiconductor has announced it has collaborated with Semtech on a compact, two-chip LoRaWAN-based module deployed by Onethinx. The highly-integrated Onethinx module is ideal for smart city applications that integrate multiple sensors and are in harsh radio environments. Using Cypress’ PSoC 6 microcontroller’s (MCU) hardware-based Secure Element functionality and Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology), the solution enables a multi-layer security architecture that isolates trust anchors for highly protected device-to-cloud connectivity.

In addition, the PSoC 6 MCU’s integrated Bluetooth Low Energy (BLE) connectivity provides a simple, low-power, out-of-band control channel. The PSoC 6 device is the industry’s lowest power, most flexible Arm Cortex-M dual-core MCU with a power slope as low as 22-μA/MHz active power for the Cortex-M4 core. The device is a natural fit with Semtech’s latest LoRa radio chip family, which offers 50% power savings in receive mode and 20% longer range over previous-generation devices.

Security is a primary concern for many smart city applications. The Onethinx module utilizes the integrated Secure Element functionality in the PSoC 6 MCU to give each LoRaWAN-based device a secret identity to securely boot, on-board, and deliver data to the cloud application. Using its mutual authentication capabilities, the PSoC 6 MCU-based, LoRa-equipped device can also receive authenticated over-the-air firmware updates.

Key provisioning and management services are provided by IoT security provider and member of the Bosch group, ESCRYPT, for a complete end-to-end, secure LoRaWAN solution. The module, offered by Cypress partner Onethinx, connects to Bosch Sensortec’s Cross Domain Development Kit (XDK) for Micro-Electromechanical Systems (MEMS) sensors and to the provisioning system from ESCRYPT to securely connect.

Firms Team to Enable LoRaWAN Availability in 10 Cities

Semtech has announced that machineQ, Comcast’s enterprise Internet of Things (IoT) network service, has connected operational LoRaWAN networks to 10 U.S. cities. The extensive and comprehensive network coverage in these markets increases access at the network edge to add value to solutions providers and enterprises, establishing a strong foundation for nationwide deployment.

According to ABI Research, IoT technology revenues across 12 key smart city technologies and verticals, including metering, parking and street lighting, is expected to grow from around $25 billion in 2017 to $62 billion in 2026 at an average growth rate of 11%. This rapid adoption will need a proven infrastructure that is able to scale and provide key LoRa capabilities to support multiple applications.
MachineQ has rolled out networks in Philadelphia, Chicago, San Francisco, Atlanta, Baltimore, Boston, Denver, Detroit, Indianapolis, Miami, Minneapolis/St. Paul, Oakland, Pittsburgh, Seattle and Washington D.C. The comprehensive network presence in these 10 cities demonstrates the steady progress of enabling smart business decisions with the broad adoption of Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology) for their smart applications.

According to Semtech, machineQ’s optimized LoRaWAN network drives even more diverse applications and IoT adoption. MachineQ’s widespread and comprehensive presence in these 10 cities demonstrates shows that Semtech’s LoRa Technology is able to support a diverse number of applications in making cities smarter, from improving parking congestion to remote lighting control for street lights.

Small Antenna Covers Bands for LPWAN, IoT and Smart Cities

Antenova has announce a new antenna, Grandis, part number SR42I010. It is an SMD antenna that is physically smaller yet provides enhanced performance in the 863-870 MHz and 902-928MHz bands. It directly targets the growing number of M2M and IoT applications using the LPWAN protocols. With Grandis, Antenova has reduced the footprint of the LPWAN antenna to 12.0 x 11.0 x 1.6mm, while also enhancing the antenna’s performance. Grandis is a low-profile antenna which uses a ground plane to radiate, and is designed to be placed in the corner of the PCB.

Antenova Grandis SR42I010

Antenova endeavours to give PCB designers the benefit of flexibility in the positioning of the antenna within a design, so the Grandis antenna is supplied is two versions, Left and Right, to give designers a choice of locations for the antenna on a PCB. LPWAN is an increasingly popular choice for IoT and smart city applications because it uses less power, which means that the batteries within individual devices will have an extended life. Antenova’s Grandis antenna covers the newer LPWAN standards for connected devices in IoT and smart cities: LoRa, SigFox and Weightless-P.
