摘要: ST 的SN250 是单片ZigBee/802.15.4 解决方案，它集成了和IEEE 802.15.4 兼容的收发
器以及16 位XAP2b 微处理器。其集成的接收通道滤波允许和现有2.4GHz 频段内的其它通
信标准如蓝牙和IEEE 802.11g 共存。它所集成的稳压器、VCO、环路滤波器以及功率放大
器使得外接元件降到最低。本文给出了SN250 的主要特性、应用范围、典型应用电路图，并介绍了一种基于SN250 的无线数据终端应用设计。

Abstract ： The SN250 is a single-chip solution that integrates a 2.4GHz ， IEEE
802.15.4-compliant transceiver with a 16-bit XAP2b microprocessor。The integrated receive
channel filtering allows for co-existence with other communication standards in the 2.4GHz
spectrum such as IEEE 802.11g and Bluetooth。 The integrated regulator, VCO, loop filter, and
power amplifier keep the external component count low。 This article has given the SN250’sprincipal characteristic, the application scope, the application circuit diagram ，and it also has introduced an application design of the wireless DTE using SN250 。
Keywords: SN250；the XAP2b microprocessor；SIF interface；an application design of the
