STMicroelectronics has released two new products to enable the next generation of better, smaller, and longer lasting smart short-range wireless connectivity devices. The latest Bluetooth specification creates exciting opportunities for these to become even smarter, allowing designers to create items such as wireless beacons and devices that can calculate their location indoors with centimeter accuracy. Plus all the other convenient features Bluetooth is known for.
ST’s latest Bluetooth solutions cut the time for designers to understand the new specifications and put new product ideas into action. In today’s fast-moving markets for wireless products, the initiative lies with teams who can quickly conceive new products that offer novel and useful features.
ST’s new STM32WB09 wireless microcontroller puts all the processing power and Bluetooth radio-frequency technology needed in one chip that designers can put directly on their board ready to connect any other components. It comes with the latest Bluetooth 5.3 software and lets designers take advantage of the vast development ecosystem ST has built to support its STM32 microcontroller family. This includes PC-based design tools, essential software, and sample code to accelerate application development.
The STM32WB09 IC, suitable for skilled designers, offers the advantage of a tiny chip-scale package option that is one of the smallest on the market today.
For customers that do not have access to extensive engineering skills and resources, ST offers the STM32WB1MMC wireless module. It makes wireless connectivity simple as it contains a certified wireless microcontroller pre-integrated with external components needed for the radio system, as well as the Bluetooth software, and so bypasses many of the engineering challenges encountered when designing with chips. The module helps product developers reduce project risks and build high-performing wireless products with only basic radio-frequency engineering skills. By doing so, customers can focus on developing their own firmware to add value as the wireless functionality will be easy to use.
To make its Bluetooth module even easier to use, ST has now introduced the B-WB1M-WPAN1 evaluation board that is ready to power-up and start development. This board also contains movement, temperature, and barometric-pressure sensors that can be incorporated into the system, and other convenient features like an industry-standard connector for attaching an external antenna.
The STM32WB09 wireless microcontroller, STM32WB1MMC turnkey wireless module, and B-WB1M-WPAN1 module evaluation board are all in production now and ready for new design starts.
About the STM32WB09 wireless microcontroller: Tailored the STM32WB09’s memory and peripherals for applications like wireless sensing, connected wearables, and remote control; Supports advanced Bluetooth 5.3 capabilities including direction and distance finding for accurate position detection, thereby enabling applications such as real-time locating, indoor positioning, item finding, and asset tracking; The new SoC also enhances the performance and affordability of warehouse inventory management systems, smart meters, medical devices including disposable sensors, and access controls; Builds around an easy-to-use Arm Cortex-M0+ single-core architecture. This core hosts the application while ST’s state-of-the-art radio manages the Bluetooth wireless connection;
While providing generous on-chip memory, ST has prioritized features that make the biggest difference in the targeted applications. These include support for power-control options in the Bluetooth radio and the ability for users to fine-tune the RF output power in 1dBm steps, which is a differentiator in the marketplace. This tuning optimizes battery life and system reliability and ensures coexistence with other nearby wireless devices.
The STM32WB09 is available now for high-volume OEM applications, from $1.36 in the QFN32 package.
