Based on an Arm® Cortex®-M4 core running at 64 MHz (application processor) and an Arm® Cortex®‐M0+ core at 32 MHz (network processor), STM32WBx5 wireless microcontrollers support Bluetooth™ 5.0 and IEEE 802.15.4 wireless standards.
Wireless connectivity
Bluetooth™ 5.0-certified, STM32WBx5 wireless MCUs can support Mesh 1.0 network, multiple profiles and flexibility to integrate proprietary Bluetooth stacks. The generic IEEE 802.15.4 MAC layer ensures the STM32WBx5 runs proprietary protocols or stacks including ZigBee® 3.0 and OpenThread low-power mesh networking protocols, giving designers even more options for connecting devices to the Internet of Things (IoT).
These ultra-low-power 32-bit wireless microcontrollers can run Bluetooth™ 5.0 and 802.15.4 wireless protocols concurrently.
Package information and options
STM32WBx5 wireless microcontrollers provide designers with flexibility in terms of pin counts and memory size.
Four ECOPACK2®-compliant packages with three different memory sizes are available to address different levels of complexity to match application requirements.
Featured Videos
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
