Description: 凭借它在手机技术领域的地位、在射频半导体工艺方面的广泛知识，飞思卡尔提供了符合IEEE 802.15.4标准的MC13192射频数据调制解调器。这种功能丰富的双向2.4GHz收发器带有一个数据调制解调器，可在ZigBee™ 技术应用中使用。它还具有一个优化的数字核心，有助于降低MCU处理功率，缩短执行周期。4个定时比较器使用一个性能较低、价格低廉的MCU，从而能够降低成本。广泛的中断维修服务使软件开发更具灵活性。PF IC和MCU之间使用串行外围接口（SPI）连接，从而使用户能够使用飞思卡尔庞大产品系列中的任何一种MCU。连接质量和电源检测可为组网和维护提供必要的数据。MC13192提供的特性包括：
◆ 根据IEEE 802.15.4标准设计，采用ZigBee™ 技术
◆ 全频谱编码和译码
◆ 经济高效的CMOS设计几乎不需要外部组件
◆ 可编程的时钟，供基带MCU使用
◆ 标准的4线SPI
◆ 扩展的范围性能（使用外部低噪音放大器（LNA）功率放大器）
◆ 可编程的输出功率，通常为0 dB
◆ 超低功耗模式
◆ 7条GPIO线路
