1 Introduction

The STM32CubeWBa MCU Package[1] provides software components running on STM32WBA MCUs.
For all examples provided with the package, the following integrated development environments are supported:

  • STMicroelectronics integrated development environment for STM32 products (STM32CubeIDE)
  • IAR Systems® IAR Embedded Workbench® for Arm® (EWARM)
  • Keil® microcontroller development kit (MDK-ARM)

The Firmware Package for the STM32WBA series is also available on STM32CubeWBA github[2].

2 STM32WBA Zigbee software architecture

The single Core Arm® Cortex®-M33 STM32WBA Zigbee solution is designed to develop application firmware including clusters and smart energy objects on top of the Zigbee Stack and 802.15.4 MAC & PHY, as depicted in the figure below.

STM32WBA5xxG Memory system:

  • 1-Mbyte flash memory from address offset 0x00 0000 to 0x0F FFFF
  • 128-Kbyte SRAMs:
    • SRAM1 64-Kbyte from address offset 0x0 0000 to 0x0 FFFF (continuous SRAM space with SRAM2)
    • SRAM2 64-Kbyte

Power Efficiency Features of Zigbee with STM32WBA
Zigbee with STM32WBA offers the ability to handle power efficiency by defining different levels of low power that can be configured based on the specific needs of the application.
Clock Frequency
At runtime, clocks are managed dynamically by the System Clock Manager (SCM) module. Input Frequency = 32MHz.

3 STM32WBA Zigbee applications

3.1 Stack and Clusters Libraries

The STM32WBA utilizes the Zigbee stack R23, which is available in two library types, FFD and RFD.
ZigBee Cluster Library ZCL8.0 is provided as a library, with the option to receive the source code under a non-disclosure agreement (NDA).
