一、CC2500芯片概要
The CC2500 is a low cost true single chip 2.4GHz transceiver designed for very low power wireless applicati***. The circuit is intended for the I*** (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 ha***are support for packet handling, data buffering, burst tran***issi***, clear channel asses***ent, link quality indication and wake-on-radio. The main operating parameters and the 64-byte tran***it/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I***（工业，科学和***）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。
