产品叙述

SiWx915 SoC 是 Wi-Fi 6 设备系列中的第二款产品，非常适用于使用 Wi-Fi®、蓝牙低功耗 (LE)、Matter 和 IP 网络进行云连接的高能效或线路供电型物联网无线设备。SiWx915 SoC 包括 Wi-Fi 6 和蓝牙 LE 无线 CPU 子系统，以及集成式微控制器 (MCU) 应用子系统、安全功能、内存、外围设备子系统，所有这些都集成在一个 7 x 7 毫米的 QFN 封装中。无线子系统由运行速度高达 160 MHz 的多线程处理器、基带数字信号处理、模拟前端、2.4 GHz RF 收发器和集成功率放大器组成。应用子系统由运行速度高达 180 MHz 的 ARM® Cortex®-M4、嵌入式 SRAM 和闪存组成。ARM® Cortex®-M4F 专门用于外围设备和应用相关处理，而多线程处理器在独立线程上运行无线和网络协议栈，因此可提供完全集成的高性能解决方案，可直接用于各种嵌入式无线物联网应用。

目标应用场景:

智能家居
消费者健康和可穿戴设备
临床医学
工业
零售
智能建筑和城市
资产跟踪
