简介
NRC7292 是业界首款符合 IEEE 802.11ah Wi-Fi HaLow 标准的系统芯片（SoC)。Wi-Fi HaLow 是专为物联网（IoT）设备而优化的Wi-Fi 解决方案。与在 2.4GHz 和 5GHz 频段运行的 Wi-Fi 技术相比，它可在低于 1GHz 的免许可频段运行，具有更广的覆盖范围和更强的材料穿透力。可配置的 1/2/4MHz 通道宽度和可选的短保护间隔 (SGI) 可产生 150 Kbps 至 15 Mbps 的 PHY 吞吐量，不仅可支持低数据速率传感器，还能支持高数据速率监控摄像头。这种网络安全协议具有省电机制，可大大降低功耗并增加电池寿命。
NRC7292 是一款自包含 IEEE 802.11ah Wi-Fi HaLow 的系统芯片，包括应用处理和网络功能以及完全集成的无线电收发器。 NRC7292 是将 Wi-Fi 连接添加到物联网产品的理想解决方案。它最大限度地减小了电路板尺寸，以最少的外部电路，实现快速进入市场时间。
RF 收发器是针对低于 1GHz 频段优化的完整无线电前端，它具有完全集成的前置功率放大器以及支持各种商用外部 FEM 设备的能力。借助双嵌入式 ARM Cortex-M0 和 Cortex-M3 处理器，NRC7292 可用作独立设备或通过串行外围接口 (SPI) 或通用异步接收器发送器 (UART) 接口连接到主机处理器。此外，它可以同时支持工作站和接入点功能。
