The STM32Wx MCUs bring wireless connectivity to the STM32 MCU portfolio. They cover Sub-GHz as well as 2.4 GHz frequency range operation. They are easy to use, reliable and perfectly tailored for a wide range of industrial and consumer applications.
STM32Wx solutions are compatible with multiple protocols, from point-to-point & mesh to wide-area networks with outstanding low-current consumptions and built-in security features. STM32Wx wireless MCUs feature a two-in-one, dual-core architecture built around an MCU and a radio transceiver, in one deeply integrated and highly cost-efficient System-on-Chip. STM32Wx solutions are thus a perfect match between real-time and/or highly power-efficient applications.
The STM32Wx platform is the ideal fit for RF designers looking for more than just a radio device.
The STM32Wx portfolio includes two series, featuring different radio protocols: the STM32WB and the STM32WL.
The STM32WB series supports Bluetooth® LE 5.2 and IEEE 802.15.4 communication protocols, Zigbee® and Thread, running either individually or concurrently. With a wide and easy-to-use ecosystem, the STM32WB series offers certified, free-of-charge radio stacks. To ensure device integrity, the STM32WB’s security features enable end-device trustability and anti-cloning features.
In order to reduce time to market and match the requirements of different levels of integration, from cost-effective PCB to high integration, the STM32WB series includes STM32WB microcontrollers, available in different packages (from UQFN48 to UFBGA129), as well as a ready-to-use module.
The STM32WL MCU series is the world’s first LoRa®-enabled System-on-Chip.
The STM32WL is fully open and supports multi-modulation, making it the ideal choice for LPWAN (Low-Power Wide Area Networks) and IoT developments with outstanding ultra-low power consumption without compromising on performance.
