Based on an Arm® Cortex®‐M4 core running at 64 MHz (application processor) and an Arm® Cortex®‐M0+ core at 32 MHz (network processor), STM32WB55 microcontrollers support Bluetooth™ 5 and IEEE 802.15.4 wireless standards.
Wireless connectivity
Bluetooth™ 5-certified, STM32WBx5 microcontrollers can support Mesh 1.0 network, multiple profiles and flexibility to integrate proprietary BLE stacks. The generic IEEE 802.15.4 MAC layer ensures that the STM32WBx5 can run proprietary protocols or stacks including ZigBee®* and Thread low-power mesh networking protocols, giving designers even more options for connecting devices to the Internet of Things (IoT).
Moreover, these ultra-low-power 32-bit microcontrollers can run Bluetooth™ 5 and 802.15.4 wireless protocols concurrently.
Package information and options
STM32WB55 microcontrollers provide designers with flexibility in terms of pin counts and memory size.
Four ECOPACK2® compliant packages, each with three different memory sizes, are available to address different levels of complexity to ensure a cost-efficient fit for application requirements.
