一、CC2500芯片概要
The CC2500 is a low cost true single chip 2.4GHz transceiver designed for very low power wireless applications. The circuit is intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band at 2400-2483.5 MHz. The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 500 kbps. The communication range can be increased by enabling a Forward Error Correction option, which is integrated in the modem. CC2500 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake-on-radio. The main operating parameters and the 64-byte transmit/receive FIFOs of CC2500 can be controlled via an SPI interface. In a typical system, the CC2500 will be used together with a microcontroller and a few additional passive components.
CC2500是一种低成本真正单片的2.4GHz收发器，为低功耗无线应用而设计。电路设定为2400-2483.5MHz的ISM（工业，科学和医学）和SRD（短距离设备）频率波段。RF收发器集成了一个数据传输率可达500kbps的高度可配置的调制解调器。通过开启集成在调制解调器上的前向误差校正选项，能使性能得到提升。CC2500为数据包处理、数据缓冲、突发数据传输、清晰信道评估、连接质量指示和电磁波激发提供广泛的硬件支持。CC2500的主要操作参数和64位传输/接收。FIFO（先进先出）可通过SPI接口控制。在一个典型系统里，CC2500和一个微控制器及若干被动元件一起使用。
