| 摘 要： | ZigBee是建立在IEEE802．15．4协议上并被不同设备制造商共同遵守的应用规范，尤其适合于无线网络，具有低成本、低功耗、低延迟和高可靠性等特点。CC2420是Chipeon公司制造的符合ZigBee标准的无线收发芯片。PXA255是Intel公司生产的32位处理器，具有小体积、数据处理能力强大的特点。该文结合两款芯片的上述特点设计出以PXA255为控制器、以CC2420为无线收发器的低功耗无线网络终端。由该终端构成的网络可以在不更换电池的情况下工作半年以上。

| Abstract: | ZigBee is a new wireless protocol stack based on IEEE 802.15.4 standard, and it is obeyed by many device manufactures. It is characterized by low cost, low power consumption, low latency and high stabilization, especially suited for the wireless network. CC2420, made by Chipcon Co, is a low - consumption, high - integration RF transceiver. PXA255, which is well known for small size and powerful data processing capability, is a 32 - bit microcontroller from Intel Corporation. This paper design a wireless network terminal which is integrated by the RF transceiver and the microcontroller described above. The ZigBee wireless network consisting of such kind of terminals can work more than six months without replacing or recharging batteries. |
