STMicroelectronics STM32WBA6 Series

The new STM32WBA6 series is used in connected, smart devices like wearable healthcare and wellness monitors, animal collars, electronic locks, remote weather sensors, and more. Packing extra memory and digital system interfaces, while preserving energy efficiency the new MCUs can handle richer functionality in emerging new product designs.

The wireless subsystem in the new STM32WBA6 microcontrollers supports Bluetooth® LE, Zigbee, Thread, Matter, and other protocols operating in the 2.4GHz frequency band, and allows communication using multiple protocols concurrently. It’s how a system like a smart-home bridge can communicate with the homeowner’s mobile app over Bluetooth and simultaneously manage lights or thermostats through mesh networking such as Zigbee. The STM32WBA6 series also contains single-protocol variants for simpler and more cost-conscious applications.

STM32WBA65I-DK1

Discovery Kit with STM32WBA65RI MCU

The STM32WBA65I-DK1 Discovery kit is a complete demonstration and development platform for the STM32WBA65RIV7 microcontroller, featuring an Arm® Cortex^®‑M33 core with Arm® TrustZone^® and mainline security extension, 2 Mbytes of flash memory, and 512 Kbytes of SRAM, as well as smart peripheral resources.

The STM32WBA65I-DK1 Discovery kit embeds a powerful and ultralow-power radio compliant with the Bluetooth^® LE SIG resources. This Discovery kit enables a wide diversity of applications by exploiting low-power communication, the Bluetooth^® SIG isochronous channel feature related to audio capability for Bluetooth^® LE audio, Matter, and Zigbee^®.

The support for ARDUINO® Uno V3 connectivity provides expansion capabilities with a wide choice of specialized add-on boards.

The STM32WBA65I-DK1 Discovery kit integrates an STLINK-V3EC embedded in-circuit debugger and programmer for the STM32 microcontroller with a USB Virtual COM port bridge. It comes with the STM32CubeWBA MCU Package, which provides an STM32 comprehensive software HAL library and various software examples.

The STM32WBA65I-DK1 Discovery kit leverages the STM32WBA series key assets to enable prototyping for a variety of wireless, low‑energy applications in fitness, metering, industry, or medicine, with state-of-the-art energy efficiency, and higher security.

NUCLEO-WBA65RI

STM32 Nucleo-64 development board with STM32WBA65RI MCU

NUCLEO-WBA52CG, NUCLEO-WBA55CG, and NUCLEO-WBA65RI are Bluetooth^® LE wireless and ultra‑low‑power boards embedding a powerful and ultra‑low‑power radio compliant with the Bluetooth^® LE SIG specification, IEEE 802.15.4-2015 PHY and MAC, supporting Thread, Matter, and Zigbee^®.

The ARDUINO^® Uno V3 connectivity support and the ST morpho headers allow the easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The Matter application project stores the device credentials and keys in the STM32 embedded flash memory, or in an external flash memory for which X-CUBE-MATTER provides a driver. Once provisioned, the security-sensitive data and operations remain in a secure partition, where they are not exposed to the user application. The Secure Boot process acts as a Root of Trust for the application before launching it. It takes care of the Secure Firmware Update once the user application has downloaded a new image.

The X-CUBE-MATTER Expansion Package embeds different sorts of open-source components:
 

• Matter SDK from CSA
• Some other third-party components selected by STMicroelectronics (such as FreeRTOS™ kernel, Mbed TLS, and LwIP) are reintegrated
• Some components implemented by STMicroelectronics (such as the Bluetooth® LE platform adaptation and the OpenThread platform adaptation)

The OpenThread and Bluetooth^® LE stacks can be located on the application microcontroller in the case of a chipset solution. They can also be located on the coprocessor dedicated to the wireless stack. Refer to the wiki site for the software partitioning of each target platform.

The delivered application examples are part of the project. They are available as precompiled binaries for an out-of-the-box experience. The source codes are also available. They can be compiled with the supported IDEs. Refer to the wiki site for the detailed list of supported applications.

The power manager framework, when embedded, is implemented in the utilities component.

STM32CubeWBA - STM32Cube MCU Package for STM32WBA series (HAL, Low-Layer APIs and CMSIS, File system, RTOS, BLE/802.15.4, Thread and Zigbee stacks - and examples running on ST boards)

STM32Cube is an STMicroelectronics original initiative to make the life of the developer easier by reducing development effort, time, and cost. STM32Cube covers the whole STM32 portfolio.

STM32Cube includes STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization code using graphical wizards.

It also comprises 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® 5.4 profiles and services), Azure® RTOS kernel, OpenBootloader, mbedTLS, TFM, MCUboot, and HCI connectivity services. All embedded software utilities are delivered with a full set of examples running on STMicroelectronics boards.

The STM32Cube HAL is an STM32 embedded software layer that ensures maximized portability across the STM32 portfolio, while the LL APIs make up a fast, light-weight, expert-oriented layer, which is closer to the hardware than the HAL. HAL and LL APIs can be used simultaneously with a few restrictions.

Both the HAL and LL APIs are production-ready and have been developed in compliance with CodeSonar®, MISRA C®:2012 guidelines and ISO/TS 16949. Furthermore, STMicroelectronics specific validation processes add a deeper-level qualification.

The STM32CubeWBA gathers in one single package all generic embedded software components required to develop an application on STM32WBA series microcontrollers. Following STM32Cube initiative, this set of components is highly portable, not only within the STM32WBA series, but also to other STM32 series. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeWBA HAL at the cost of portability and simplicity.

HAL and LL APIs are available in open-source BSD license for user convenience.
