Renesas Synergy™ goes LoRa® with the new, tiny FMLR-61-U-RSS3 modules equipped with the latest software “LoRa Basics™ MAC” and now available at Avnet Silica.

Everybody wants to connect “things” to the “IoT”  and LoRa® is the ultimate technology to do so across long distances (up to 50km LOS). The new, tiny FMLR-61-U-RSS3 module, designed by Miromico, comes with the latest software “LoRa Basics™ MAC” and is now available in early samples exclusively from Avnet Silica. Of course, it comes with the giant Synergy Software Package (SSP)  to enable you to add your own functionality quickly.

The FMLR-61-U-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). Receiver sensitivity is -148dBm in LoRa mode SF12@10.4 kHz, and the module’s operating temperature range is -40 to 85°C. The module’s exceptional specifications make it ideal for urban as well as rural sensing applications such as metering, asset tracking, building automation, security, wearables, predictive maintenance and more.

The FMLR-61-U-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, which is enough memory to allow engineers to add a variety of their own functions. Most MCU signals are available at the module level to make them externally accessible. Manufactured in a low- power process, 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. Various timer channels and serial ports, USB function, CAN, DMA, and powerful safety and security hardware makes the S3A6 an ideal MCU for a wide range of battery-operated applications.

The Renesas Synergy Platform features the Synergy Software Package (SSP), which comprises a large selection of production-grade software. SSP includes the ThreadX® RTOS and lots of associated middleware such as a file system, USB stack, graphical user interface (GUI) software, application frameworks and functional libraries that can be used for encryption and DSP functions. This unique and powerful combination of hardware and software helps customers significantly accelerate their product development schedule.
