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

Bluetooth5.0-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.
