Semtech Corp. and DTDS Technology have developed a LoRaWAN module that leverages Renesas’s RL78 microcontroller (MCU) for very low power consumption and increased network coverage in automotive and industrial IoT (IIoT) applications. The 622 Module offers long range connectivity and low operating power, while helping to simplify the development of IoT products.
Based on Semtech’s SX1262 LoRa-based communications device, controlled by Renesas’s RL78/G13 MCU, the 622 Module is LoRaWAN-compliant with Class A and Class C of the protocol. The embedded Renesas RL78/G13 MCU provides low power consumption of 66 μA/MHz and performance at 43.2 DMIPS (32 MHz) for applications such as smart utility, smart home, smart agriculture, smart lighting, and smart transportation applications. Supporting 868 MHz, 915 MHz and 923 MHz operation bands, the LoRaWAN module is suited for long range sensor-based interfaces with an external host MCU over AT commands.
Other features include an antenna matching network for a 50-Ω termination and a TCXO-enabled clock. The operating temperature range is -40°C to 85°C and the standby current is < 4 mA. Receiver sensitivity is -137dBm @ SF12 BW=125 KHz. The module measures 15 (W) x 27 (L) x 3 (H) mm.
Designed to streamline the development process and support the deployment of large, scalable LPWANs, the LoRaWAN module enables IoT products to be deployed in harsh radio environments. DTDS said the goal is to simplify device creation, enabling designers to bring wireless products to market quicker.
The module also supports remote firmware updates and the ability to join different LoRaWAN networks based on the deployment need, said Semtech.
An evaluation board is available with an industry standard pMOD interface and two antenna connector interfaces (SMA, UFL) for development.
