The STM32WBA6 series is used in connected, smart devices like wearable healthcare and wellness monitors, electronic locks and remote weather sensors. With extra memory and digital system interfaces, while preserving energy efficiency, the new MCUs can handle richer functionality in emerging new product designs.
These MCUs also embed SESIP3 and PSA Level3 certifiable security assets, such as cryptographic accelerators, TrustZone isolation, random generator, and product lifecycle that will contribute and enable ST customers to reach compliancy towards the upcoming RED and CRA regulations.
The wireless subsystem in the new STM32WBA6 microcontrollers supports Bluetooth, Zigbee, Thread, Matter, and other protocols operating in the 2.4GHz frequency band, and allows communication using multiple protocols concurrently.
The STM32WBA6 series also contains single-protocol variants for simpler and more cost-conscious applications.
By integrating the processing core, peripherals, and wireless subsystem, these new MCUs will help product developers to simplify new designs, miniaturise assembly size, and save on the electronic bill-of-materials.
In addition, with up to double the Flash and RAM on-chip, compared to the previous STM32WBA5 series, these new MCUs also provide generous storage for application code and data. The richer digital peripherals add USB High Speed as well as extra digital interfaces including three SPI ports, four I2C ports, three USARTs, and one LPUART
The STM32WBA6 series is powered by the energy-efficient Arm Cortex-M33 core, with floating-point unit and DSP extensions, running at up to 100MHz.
The STM32WBA5 and STM32WBA6 also support the latest EU Radio Equipment Directive (RED) cyber-security requirements.
The STM32WBA6 MCUs are now in production.
