STM32WB5MMG -STM32无线MCU模块，用于提高BLE和IoT设备的设计生产率

STMicroelectronics has introduced a miniature ready-to-useSTM32 wireless microcontroller (MCU) modulefor faster introduction ofnew Bluetooth LE and 802.15.4 based IoT devices.This new 7mm x 11.3mmSTM32WB5MMG moduleenables developers to build connected devices without needing wireless-design skills.Made to enable low-cost PCB technology requiring a minimal number of layers, the module integrates everything up to the antenna.Moreover, the crystal-less USB full-speed connectivity helps in reducing the bill-of-materials costs and also simplifies the hardware design.

The module also supports ST’s novel concurrent dual-protocol mode that lets any protocol based on IEEE 802.15.4 radio technology, includingZigbee 3.0 and OpenThread, connect the user directly to any Bluetooth Low Energy device. The devices are protected by various software updates like 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.

The device has been designed to support a large variety of smart-home, smart-building, and smart factory equipment. Users can leverage the MCU’s dual-core architecture that separates radio and application-level processing for unimpeded performance, large memories for radio and application code and data storage, and state-of-the-art cybersecurity.
