Cypress, Semtech LoRaWAN IoT solution targets smart cities
Cypress Semiconductor (San Jose, CA) and Semtech Corporation (Camarillo, CA) have announced a collaboration on a compact, two-chip LoRaWAN-based module offered as being ideal for smart city applications that integrate multiple sensors and are in harsh radio environments.

The module, which is offered by Cypress partner and Internet of Things (IoT) company Onethinx (Zwolle, Netherlands), uses Cypress' PSoC 6 microcontroller's hardware-based Secure Element functionality and Semtech's LoRa devices and wireless radio frequency technology. The solution, say the companies, enables a multi-layer security architecture that isolates trust anchors for highly protected device-to-cloud connectivity.

In addition, the PSoC 6 MCU offers integrated Bluetooth Low Energy (BLE) connectivity for a simple, low-power, out-of-band control channel. The PSoC 6 device - offered as the industry's lowest power, most flexible Arm Cortex-M dual-core MCU - 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, the companies say.

The Onethinx module uses the PSOC 6's Secure Element functionality 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 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 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.

"With its long range and low power capabilities in a compact footprint, Semtech’s LoRa Technology is ideal for vertical applications," says Vivek Mohan, Director of IoT in Semtech's Wireless and Sensing Products Group. "Combining LoRa Technology with Cypress' PSoC 6 MCU in a purpose-built IoT module will accelerate the delivery of leading-edge IoT solutions for smarter cities and a smarter planet."

Jack Ogawa, senior director of marketing for the MCU business unit at Cypress adds, "Devices for LoRaWAN networks need to be secure to protect the data they generate and process. We're excited to work with LoRaWAN ecosystem members to offer developers the unique combination
