Overview

The STM32WLE5JCI6 is a highly integrated System-on-Chip (SoC) that combines an Arm Cortex-M4 microcontroller with a sub-GHz radio capable of LoRa, (G)FSK, (G)MSK, and BPSK modulations. It operates in the 150MHz to 960MHz frequency range and features a high-efficiency power management system with an integrated SMPS to minimize power consumption in battery-operated IoT applications.

Why Choose This Part

This SoC eliminates the need for an external RF transceiver, reducing PCB complexity and BOM cost while achieving -148dBm sensitivity. It provides a dual-power radio output up to 22dBm and ultra-low power states, including a 0.031uA shutdown mode and a 0.36uA standby mode.

Applications

Smart Utility Metering
Ideal for long-range water, gas, and electricity meters that require reliable data transmission from deep indoors or underground.
Agricultural Monitoring
Enables soil moisture, temperature, and livestock tracking over several kilometers with multi-year battery life.
Asset Tracking
Small 5x5mm UFBGA footprint allows for compact industrial trackers monitoring logistics and equipment movement via LoRaWAN.
Smart Building Automation
Provides the range needed to penetrate thick walls for HVAC control, occupancy sensing, and security systems.

Getting Started

Engineers can begin development with the STM32CubeWL MCU Package, which includes the LoRaWAN and Sigfox stacks. Use the STM32CubeIDE for code development and STM32CubeMX for configuring the sub-GHz radio parameters and peripheral pinout. Hardware evaluation is typically performed using the NUCLEO-WL55JC development board.
