The performance, efficiency, and security required for Bluetooth® Low Energy 5.3 applications.
Certified for Bluetooth® Low Energy 5.3 protocol with +10dBm of output power, this product series allows nonexpert developers to easily add wireless communication to their device, at an affordable cost.
Based on the Arm® Cortex®-M33 core featuring TrustZone® technology, the STM32WBA series provides a high level of security, protecting data, IP, and preventing hacks or device cloning. The STM32WBA wireless MCU embeds 1 Mbyte of flash memory and 128 Kbytes of RAM.
Leveraging the STM32U5 architecture, the STM32WBA series offers the same digital and analog peripherals, suitable for many applications, from industrial, to smart home and consumer markets.
With +10dBm of output power for better robustness

SESIP level 3 target certification

The STM32CubeWBA MCU Package, composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components such as STMTouch™, STM32_WPAN (Bluetooth® 5.3 profiles and services), Azure® RTOS kernel, OpenBootloader, mbedTLS, TFM, MCUboot, and HCI connectivity services.
The STM32CubeMonitor-RF (STM32CubeMonRF) is a software tool allowing the test of the radio performances of STM32WB based hardware devices on Bluetooth® Low Energy and 802.15.4 technologies. It provides a graphical display to verify RF performance, with transmission/reception tests and packet error rate (PER) measurements. Results can be plotted to visualize the evolution of performance over time.
