The ideal fit for RF designers looking for more than a simple radio device.

The STM32Wx microcontrollers enable wireless connectivity. They support the sub-GHz band and the 2.4 GHz frequency range. Highly integrated and reliable, they address a wide range of industrial and consumer applications.

STM32Wx solutions are compatible with multiple protocols, from point-to-point & mesh to wide-area networks. They are power efficient and offer built-in security features.

STM32Wx wireless MCUs feature a two-in-one, dual-core architecture. Built around an MCU and a radio transceiver, STM32Wx MCUs come in one deeply integrated and highly cost-efficient System-on-Chip. STM32Wx solutions enable real-time performance while ensuring efficient power consumption.

    Featuring different radio protocols, the STM32Wx portfolio includes 3 series:
  • The STM32WB, the STM32WB0 and the STM32WBA series for short-range connectivity
  • The STM32WL series for long-range connectivity
