STM32WBx0 Value Line

The STM32WBx0 is a dual-core wireless MCU based on an Arm® Cortex®‐M4 core running at 64 MHz (application processor) and an Arm® Cortex®‐M0+ core at 32 MHz (network processor).

The STM32WBx0 Value Line is an entry-level solution, extending our portfolio to allow developers to define the right level of features so their design is cost-efficient and meets the requirements of a broad range of industrial and consumer IoT applications.

Thanks to its low-power stop mode and best-in-class RF performance, the STM32WBx0 Value Line provides application connectivity with an extended battery life, making it ideal for point-to-point or meshed applications such as innovative location-based services in retail marketing, asset tracking, beaconing and more.

Wireless connectivity


Providing flexibility and scalability to your wireless design, the STM32WBx0 Value Line of wireless microcontrollers addresses Bluetooth® LE 5.4-certified stack and supports Mesh 1.0 network, and multiple profiles. It can also run several protocols including IEEE 802.15.4 with Zigbee® PRO and its wide set of Zigbee 3.0 clusters, as well as OpenThread mesh networking protocols.

  • The STM32WB50 with 1 Mbyte of Flash memory ensures your application runs smoothly, whatever the protocol stack and application solution, without requiring an external Flash memory component
  • The STM32WB30 is a scalable solution that matches various levels of device complexity for Bluetooth LE or 802.15.4 technologies
    The STM32WB10 is suitable for basic Bluetooth LE applications. Offering the right balance between cost and connectivity, it provides the necessary MCU features to enable wireless connectivity in entry-cost IoT devices

Package information

STM32WBx0 wireless microcontrollers are based on the QFN48 package, pin-to-pin compatible with the QFN48 of the STM32WBx5 series (ECOPACK2® compliant package). The STM32WBx0 line features memory capability to support the entire software platform.

Development ecosystem

The STM32WB55 Nucleo pack and STM32WB Nucleo boards with STM32Cube Ecosystem form a consistent set of development tools to quickly and easily start developing your application across the whole STM32WB portfolio.
