Additionally, the module supports protocol based on IEEE 802.15.4 radio technology, including Zigbee 3.0 and OpenThread, connecting the user directly to any Bluetooth Low Energy device.

Leveraging the features of STM32WB55 ultra-low power wireless microcontroller ICs, the module addresses applications for smart-home, smart-building and smart-factory equipment. The MCU’s dual-core architecture separates radio and application-level processing for unimpeded performance, large memories for radio and application code and data storage.

Included cybersecurity features are secured software updates including Over-The-Air (OTA) for brand protection and device integrity, customer key storage and Proprietary Code Readout Protection (PCROP) to protect developers’ intellectual property, and Public Key Authentication (PKA) support for cryptographic protection of code and connections.

By combining high RF performance with low power consumption, the module ensures reliable connectivity with extended battery life.

The STM32WB5MMG is available now in a 7mm x 11.3mm package from STMicroelectronics.
