简介
NRC5294 中集成的单个嵌入式 ARM® 处理器 Cortex-M3 提供足够的处理能力，足以在单个 Wi-Fi SoC 中同时运行 Wi-Fi 子系统和用户应用程序。NRC5294 还包含主机接口 UART 和丰富的外部设备，例如通用 SPI、I2C、UART、PWM、辅助 ADC 和 GPIO。低泄漏保持存储器可用于存储从深度睡眠模式快速唤醒所需的代码和数据。
安全性是 NRC5294 的关键特性，它支持安全启动，并具备多项高级安全功能，包括加密模块、安全密钥存储、真随机数生成器和调试端口禁用机制。为了保护外部闪存中的用户代码，NRC5294 支持加密的 XIP 模式。
Newracom 的专有射频收发器是一个完整的无线电前端，针对 1 GHz 以下频段进行了优化。它集成了功率放大器 (PA)、分数 N 合成器，并能够支持各种商用外部前端模块 (FEM) 设备。接收机的射频和基带内部数字控制增益级可提供低噪声系数和大动态范围。此外，发射机具有超过30 dB的增益范围，从而提供宽广的输出功率范围。
