March 6, 2024 /SemiMedia/ -- STMicroelectronics has revealed the next generation of its 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 ever more miniaturized, easy to use, secure and affordable.
ST’s new STM32WBA5 product line allow a one-chip solution that’s extremely compact, reduces the bill of materials, and shortens the time to market by relieving wireless design challenges. Also, being compatible with the development tools and software packs of the STM32 microcontroller development ecosystem, the new line simplifies migrating existing products designed for wired connections.
The new series’ flagship STM32WBA55 microcontroller can communicate using multiple wireless standards concurrently, including low-energy Bluetooth LE 5.4, Zigbee, Thread, and Matter (Thread RCP). Matter border router is a perfect match with the STM32WBA5 for this new open-source connectivity standard for smart-home and IoT (Internet of Things) devices. In this way, the STM32WBA55 supports a great user experience while simplifying hardware and software engineers’ development journey, aiding affordability and time to market for the new product.
With this new generation, ST has also introduced support for the recently completed Bluetooth LE Audio specifications that enable exciting and innovative new products for richer listening and hearing experiences. These include the new Bluetooth Auracast™ feature, which opens the door to a new world of audio broadcasting applications.
“Lead customers are already appreciating the enhanced wireless performance, flexibility, and security of our latest STM32WBA wireless microcontrollers. They are creating diverse products including smart thermostats, tracking devices, smart chargers, headsets, power tools, and smart meters,” said Benoit Rodrigues, Wireless MCU Division General Manager, STMicroelectronics. “The extensive software ecosystem that provides communication stacks, microcontroller-specific software packs, sample code, and tools helps developers bring new products to market based on these MCUs quickly and efficiently.”
The STM32WBA series is the first wireless MCU in the market to achieve the important 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.
“We work with smart asset tracking devices which are connected through Bluetooth to mobiles and through mobile apps to the cloud, enabling us to deliver complete asset tracking management for our customers. ST’s microcontrollers bring wireless connectivity to our multi-mode trackers,” said Olivier Hersent, CEO, Abeeway (Actility Group). “We have selected the new wireless connectivity product, STM32WBA5, for its enhanced performance with ultra-low power radio capabilities, which is key for our battery powered devices. They ensure stable connectivity in the harsh industrial environment where we operate, combined with security that meets the highest industry standards.”
“We believe that gaming peripherals should be as unique and accessible as the gaming community itself,” said Tom Roberts, CTO, Performance Designed Products (PDP). “ST and PDP have worked together through several Video Game generations, and we have used STM8 and STM32 devices for many years. ST products consistently provide the features we need in our highly competitive market segment. We recently selected ST’s short-range wireless connectivity product, the STM32WBA5, based on the integrated MCU and Bluetooth low-energy technology, as the right solution for a new, groundbreaking game controller. The STM32WBA offered us an ideal combination of performance, peripherals, cost efficiency and ecosystem support that enabled simple and fast development.”
