    Power-Efficient Wireless Microcontrollers

    STMicroelectronics announced the next generation of its STM32 power-efficient short-range wireless microcontrollers (MCUs) that simplify connecting consumer and industrial devices to the IoT. The new STM32WBA6 series is used in a wide range of connected, smart devices. Packing extra memory and digital system interfaces, while preserving energy efficiency the new MCUs can handle richer functionality in emerging new product designs. The 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.

    Wide protocoll support

    Customers can now increase the pace of development to meet demands from consumer and industrial markets for new products that deliver more features and increased capabilities within reduced size and power constraints. 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.

    With up to 2MB of Flash and 512KB RAM on-chip, the new STM32WBA6 MCUs contain larger memory to support more sophisticated applications. 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 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 support the latest EU Radio Equipment Directive (RED) cyber-security requirements. Their SESIP3 certification target will greatly ease the customer device conformance.
