Long-range wireless STM32WL5 microcontrollers

Complementing the STM32 RF connectivity portfolio, the STM32WL5 System-On-Chip integrates both a general purpose microcontroller and a sub-GHz radio on the same chip. (System-on-Chip = one single silicon die).

Built on an Arm® Cortex®‐M4 and Cortex-M0+ cores architecture, STM32WL5 microcontrollers also support multiple modulations– LoRa®, (G)FSK, (G)MSK, BPSK – to ensure flexibility in wireless applications with LoRaWAN® or any other suitable protocol in a fully open way.

STM32WL5 microcontrollers feature a sub-GHz radio based-on Semtech SX126x to meet the requirements of a wide range of Low-Power Wide Area Network (LPWAN) wireless applications in industrial and consumer Internet-of-Things (IoT).

Thanks to a deep integration, the innovative and open architecture is optimized for LoRaWAN® legacy / proprietary protocols, flexible resource use, power management and helps lower BOM cost while offering a better user experience.

The STM32WL5 platform being fully open, a LoRaWAN stack is made available by STMicroelectronics.

Developed using the same technology as the one implemented in the ultra-low-power STM32L4 microcontrollers, the STM32WL5 series provides a similar digital and analog peripherals for basic or complex application use cases requiring an extended battery life and a long RF range through its sub-GHz transceiver.

To ensure worldwide compatibility, the STM32WL5 MCUs feature a dual power-output and a wide linear frequency range fitting any unlicensed RF spectrum need.
Overall, the STM32WL5 series is the STM32 family’s pioneer in sub-GHz wireless connectivity, offering ease-of-use and reliability, while being perfectly tailored for a wide range of industrial and consumer applications.

Wireless connectivity

STM32WL55 microcontrollers comply with the physical layer requirements of the LoRaWAN® specification released by the LoRa Alliance®. Available LoRa®, (G)FSK, (G)MSK and BPSK modulations can also be used in legacy and proprietary protocols.

Continuous frequency coverage from 150 to 960 MHz enables the support of all major sub-GHz ISM bands around the world.

System peripherals

The STM32WL55 line includes a wide variety of communication features including up to 43 GPIOs, an integrated SMPS for power consumption optimization, multiple low-power modes to maximize battery life. A dual-power output and a wide linear frequency range ensure worldwide compatibility.

Security & ID

In addition to its wireless and ultra-low-power features, STM32WL5 microcontrollers include embedded security hardware functions such as 128- / 256-bit AES hardware encryption, PCROP read / write protection, and public-key cryptography with an elliptic curve encryption engine.

On top of these, the dual-core STM32WL5x line includes advanced security features such as: Key Management Services (KMS), hardware isolation with trusted zones, secure boot and secure firmware update.
