STMicroelectronics offers their STM32WB wireless Arm Cortex-M4 microcontroller.
This microcontroller is a dual-core, multi-protocol 2.4 gigahertz system-on-chip. It supports Bluetooth 5 and IEEE 802.15.4 communication protocols in single and concurrent modes to cover a wide spectrum of IoT application needs. Based on the ultra-low-power STM32L4 microcontroller, the STM32WB is designed to reduce development time and cost, extend application battery life, and features a rich and flexible peripheral set. The microcontroller’s dual-core architecture enables real-time execution of both application code and network-processing tasks.
The dedicated Arm Cortex-M0+ network-processing controller contains protocol stacks including:
- STMicroelectronics' OpenThread stack
- Zigbee 3.0 stack
- Bluetooth 5 stack with mesh 1.0 support
