STMicroelectronics STM32WBA5 wireless microcontrollers

STMicroelectronics has launched the STM32WBA5 series of short-range wireless microcontrollers. These innovative, all-in-one components enable wearables and smart objects, including smart home devices, health monitors and smart appliances, to become more miniaturised and easy to use.

The series is compatible with the development tools and software packs of the STM32 microcontroller development ecosystem, thereby simplifying the process of migrating existing products designed for wired connections.

The microcontroller can communicate using multiple wireless standards concurrently, including low-energy Bluetooth LE 5.4, Zigbee, Thread and Matter (Thread RCP). The matter border router is also a match with the STM32WBA5 for this new open-source connectivity standard for smart home and IoT (Internet of Things) devices. In this way, the wireless microcontroller supports user experiences while simplifying hardware and software engineers’ development journey.

With this new generation, ST has also introduced support for the Bluetooth LE Audio specifications that enable innovative new products for enhanced listening and hearing experiences. These include the Bluetooth Auracast feature.

The STM32WBA series has also achieved the SESIP (Security Evaluation Standard for IoT Platforms) Level 3 security certification. With this, smart devices containing STM32WBA microcontrollers are ready to satisfy the US Cyber Trust Mark and EU Radio Equipment Directive (RED) regulations due to become mandatory in 2025.
