New LoRa module

   

New LoRa module

The collaboration between Renesas and Miromico has produced the compact, low-power FMLR-61-x-RSS3 LoRa wireless module. It employs the Renesas Synergy Platform, giving customers access to microcontrollers (MCUs) and a large production-grade software package.

Engineers can use the S3A6 MCU on the LoRa-based module to handle various tasks, while seamlessly streaming data across a LoRaWAN-based network to the cloud. The LoRaWAN protocol is quickly becoming an important standard to connect the “Things” of the Internet of Things (IoT) across long distances (up to 50km), flexibly and securely, while keeping batteries alive for years. Both Renesas and Miromico are LoRa Alliance members.

The FMLR-61-x-RSS3 module is only 14.2mm x 19.5mm in size. Its operating voltage is 1.8V to 3.3V, and the module’s power consumption ranges from just 1.4uA in sleep mode to 25.5mA (typical) in TX mode (14dBm). A highlight of the module is the use of the new licensed LoRaWAN stack with Firmware-Over-The-Air (FOTA) capabilities. Designed to meet all relevant certifications, the module can be used as a mass-produced LoRa solution in the field. The module’s specifications make it well suited for urban as well as rural sensing applications such as metering, asset tracking, building automation, security, wearables, predictive maintenance and more.

The FMLR-61-x-RSS3 module employs the S3A6 MCU with integrated 48 MHz Arm Cortex-M4 core, and features 256 KB code flash memory, 8 KB data flash, and 32 KB SRAM. The S3A6 peripheral set includes analog features such as a 14-bit SAR analog- to-digital converter (ADC), 12-bit digital-to-analog converter (DAC), op amps, and comparators. In addition, the S3A6 is part of a large Renesas Synergy MCU portfolio, making it easy to scale up to more functionality or scale down for cost optimization.
