At the top of the range of STM32WBA6 products, the STM32WBA64/65 MCUs support Bluetooth® Low Energy, Zigbee, Thread, Matter and other protocols operating in the 2.4 GHz frequency band, and allows communication using multiple protocols concurrently. A typical use case is a smart home bridge which can communicate with a resident’s mobile app over a Bluetooth link and simultaneously manage lights or thermostats through a Zigbee mesh network. The MCUs are supported by the X-CUBE-MATTER software package, which provides a Matter software development kit and application examples to ease development.
The STM32WBA6 series also contains single-protocol variants for simpler and more cost-conscious applications.
Featuring more Flash and RAM memory on-chip than the previous STM32WBA5 series, the new STM32WBA6 MCUs provide generous storage capacity for application code and data. The STM32WBA6 also offers more digital interfaces, including USB High Speed alongside three SPI ports, 14 GPIOs, four I2C ports, three USART interfaces, and one LPUART interface.
All the STM32WBA6 MCUs are based on an Arm® Cortex®-M33 CPU core, with floating-point unit and DSP extensions, running at up to 100 MHz.
The MCUs feature hardware security features which enable host systems to be certified to SESIP Level 3 and PSA Level 3. These include cryptographic accelerators, TrustZone® isolation, and a random number generator. These features also enable both the STM32WBA5 and STM32WBA6 series MCUs to meet the requirements of the latest EU Radio Equipment Directive (RED) cybersecurity regulation.
Development boards
The NUCLEO-WBA65RI from STMicroelectronics is a wireless board which demonstrates the ultra low-power radio in the STM32WBA6 series wireless MCUs. The board’s ARDUINO Uno V3 and ST morpho headers allow for easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.
Other features include:
ST also supplies the STM32WBA65I-DK1 Discovery kit, a complete demonstration and development platform for the STM32WBA65RIV7. The STM32WBA65I-DK1 Discovery kit takes advantage of the key capabilities of the STM32WBA series MCUs to enable prototyping for a variety of wireless, low‑energy applications in fitness, metering, industry, and medicine, while providing state-of-the-art energy efficiency and security.
