STMicroelectronics STM32WB55 Wireless Microcontroller is a dual-core, multi-protocol 2.4GHz MCU System-on-Chip (SoC). The STM32WB5x series supports Bluetooth®5 as well as IEEE 802.15.4 communication protocols (in Single and Concurrent modes) covering a wide spectrum of IoT application needs.

Based on the ultra-low-power STM32L4 MCU, the STM32WB is designed to reduce development time and cost, extend application battery life, and inspire innovation thanks to its rich and flexible peripheral set. The dual-core architecture of the STM32WB enables real-time execution of both application code and network-processing tasks.

As a result, developers can ensure an outstanding end-user experience while also taking advantage of the flexibility to optimize system resources, power consumption, and material costs.

The Arm® Cortex®-M0+ network-processing controller contains protocol stacks including the STMicroelectronics OpenThread Stack and the Bluetooth 5 stack, available in our STM32CubeWB FW package.

State-of-the-art protection features, essential to protect user data and help protect intellectual property in smart connected devices, include embedded customer-key storage, an elliptic curve encryption engine for Public Key Authentication (PKA), and hardware support for AES 256-bit cryptography. Developers can also future-proof products in the field, leveraging Secure Firmware Update (SFU) and support for Root Secure Service (RSS) to authenticate Over the Air (OTA) updates.
