![SiWx915 無線 SoCs | Wi-Fi 6 + 低功耗藍牙 5.4](https://www.edomtech.com/upload/catalog_list_pic/twL_catalog_24E23_VZwj76PU3e.png)
產品敘述產品規格
SiWx915 SoC 是 Wi-Fi 6 裝置系列中的第二款產品,非常適合使用Wi-Fi®、藍牙低功耗(LE)、Matter 和 IP 網路進行雲端連線的高能源效率或線路供電型物聯網無線裝置。SiWx915 SoC 包括 Wi-Fi 6 和藍牙 LE 無線 CPU 子系統,以及整合式微控制器(MCU) 應用子系統、安全功能、記憶體、週邊設備子系統,所有這些都整合在一個 7 x 7 毫米的 QFN 封裝中。無線子系統由運轉速度高達 160 MHz 的多執行緒處理器、基頻數位訊號處理、類比前端、2.4 GHz RF 收發器和整合式功率放大器組成。應用子系統由運行速度高達180 MHz 的ARM® Cortex®-M4、嵌入式SRAM 和快閃記憶體組成。 ARM® Cortex®-M4F 專門用於週邊設備和應用相關處理,而多執行緒處理器在獨立執行緒上運行無線和網路協定棧,因此可提供完全整合的高效能解決方案,可直接用於各種嵌入式無線物聯網應用。
