应用范围
􀁺 运行于 470/950 MHz ISM/SRD 频带的超低功耗无线应用
􀁺 无线传感网络
􀁺 家庭和楼宇自动化
􀁺 高级抄表架构 (AMI)
􀁺 无线计量
􀁺 无线告警和安全系统
产品描述
CC1100E 是一款 Sub-GHz 高性能射频收发器，设计旨在用于极低功耗 RF
应用。其主要针对工业、科研和医疗 (ISM) 以及 470-510 MHz 和 950-960
MHz 频带的短距离无线通信设备 (SRD)。CC1100E 特别适合于那些针对日本
ARIB STD-T96 标准和中国 470-510 MHz 短距离通信设备的无线应用。
CC1100E 在代码、封装和外引脚方面均与 CC1101[1] 和 CC1100 [2] RF 收发
器兼容。CC1100E、CC1101 以及 CC1100 均支持互补频带，可用于全球最为
常用的开放式低于 1 GHz 频率的 RF 设计：
􀁺 CC1100E：470-510 MHz 和 950-960 MHz
􀁺 CC1101：300-348 MHz，387-464 MHz 和 779-928 MHz
􀁺 CC1100：300-348 MHz，400-464 MHz 和 800-928 MHz
CC1100E RF 收发器与一个高度可配置的基带调制解调器集成在一起。该调制
解调器支持各种调制格式，并且拥有高达 500 kBaud 的可配置数据速率。
CC1100E 可提供对数据包处理、数据缓冲、突发传输、空闲信道评估、链路质
量指示以及无线唤醒的广泛硬件支持。
我们可通过一个 SPI 接口对 CC1100E 的主要运行参数和 64 字节发送/接收
FIFO 进行控制。一个典型的系统中，CC1100E 通常会与一颗微控制器以及少
数附加无源组件一起使用。
在没有事先得到德州仪器 (TI) 书面许可的情况下，不得将该产品用于下列任何产品或系统中：
（1）植入式心律管理系统，包括无限制起搏器、除颤器和心脏再同步设备，
（2）直接与一个或多个植入式医疗设备通信的外部心律管理系统；或
（3）用于监控或治疗心脏功能的其它设备，包括无限制压力传感器、生物化学传感器和神经刺激器。
