双核多协议无线STM32WB微控制器
STM32WB55微控制器基于运行于64 MHz的® Cortex®‐M4核心（应用处理器）和运行于32 MHz的Arm® Cortex®‐M0+核心（网络处理器），支持Bluetooth™ 5和IEEE 802.15.4无线标准。
这两个完全独立的核心使该创新型架构得以最优化地支持实时执行（与无线电相关的软件处理）、灵活的资源使用和电源管理，从而实现更低的BOM成本和更好的用户体验。
我们的STM32WB系列采用与超低功耗STM32L4微控制器相同的技术开发，提供相同的数字和模拟外设，适用于需要延长电池寿命和复杂功能的应用。
无线连接
STM32WB55微控制器符合Bluetooth™ 5认证，支持Mesh 1.0网络和多种配置文件，可灵活地集成专有BLE栈。通用的IEEE 802.15.4 MAC层确保STM32WB55可以运行专有协议或栈，包括ZigBee®*和Thread低功耗Mesh网络协议，为设计人员提供更多将设备连接到物联网（IoT）的选项。
此外，这些超低功耗的32位微控制器可以同时运行Bluetooth™ 5和802.15.4无线协议。
系统外设
STM32WB55系列包含很多种通信功能，包括实用的无晶振USB 2.0 FS接口、音频支持、LCD驱动、触摸感应、多达72个GPIO、用于优化功耗的集成SMPS和多种低功耗模式以最大限度地延长电池寿命。
安全与ID
除了具有无线和超低功耗特性，STM32WB55微控制器还包含嵌入式安全硬件功能，如256位AES硬件加密、PCROP读写保护、JTAG熔丝位、采用椭圆曲线加密引擎的公钥加密。根安全服务（RSS）特性确保安全地无线堆栈更新和加密密钥管理，提供进一步保护。
开发生态系统
我们的STM32WB55 Nucleo套装包括两块配备STM32WB微控制器的开发板，支持广泛的无线应用，有助于开发人员快速上手并轻松地开发应用。
围绕STM32Cube开发生态系统而构建的，全面完整的STM32CubeWB MCU包内含HAL和LL外设驱动、全套中间件和连接栈，以及各种软件示例完整套装。
除了嵌入的调试工具可以帮助您根据现有示例开发和测试自己的应用，STM32WB55 Nucleo开发板还有多种电源选项，可以通过ST-LINK USB连接器、长寿命的电池单元或外部电源供电。

How to program the STM32WB dual core in single operation, through STM32CubeProgrammer or through code example delivered in Software package.
MadeForSTM32™ is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32™ is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
We asked Nathalie the following questions: - Why is the STM32WB the best product for 2.4GHz design? - How can the STM32WB accelerate customer development? - How can STM32WB help tackle hidden system cost? - Can we see a quick demo?
New STM32WBx0 Value Line focuses on the essentials
Extending our portfolio of wireless microcontrollers, the feature-optimized STM32WBx0 Value line enables the design of cost-efficient connected devices running Bluetooth™ 5.0 Low Energy, OpenThread, or ZigBee 3.0 stacks. With its energy-saving technologies, 1 Mbyte Flash Memory and 128 Kbytes RAM and embedded security for safe OTA updates, the STM32WBx0 Value Line is ideal for industrial and consumer IoT applications.
The STM32WB50CG MCU, housed in a QFN48 package, is now in production. Dedicated STM32Cube development tools are available.
