Overview

The STM32WLE5CCU6 is a highly integrated System-on-Chip (SoC) that combines an Arm Cortex-M4 microcontroller with a long-range sub-GHz radio on a single die. It is designed for LPWAN applications, supporting LoRa, (G)FSK, (G)MSK, and BPSK modulations to provide versatile wireless connectivity with high energy efficiency.

Why Choose This Part

This SoC eliminates the need for an external RF transceiver, reducing PCB footprint and BOM cost. It offers exceptional sensitivity of -148dBm and a high power output of up to 22dBm, while maintaining ultra-low power consumption with a shutdown current of 0.031uA.

Applications

Smart Agriculture
Soil moisture and environmental monitoring using LoRaWAN for long-range data transmission in rural areas.
Industrial IoT (IIoT)
Remote asset tracking and predictive maintenance sensors in large-scale industrial facilities.
Utility Metering
Automated reading of water, gas, and electricity meters requiring multi-year battery life.
Smart Cities
Street lighting control and waste management systems utilizing Sigfox or LoRa networks.
