PT2262/2272是一种CMOS工艺制造的低功耗低价位通用编解码电路，是目前在无线通讯电路中作地址编码识别最常用的芯片之一。PT2262/2272最多可有12位（A0-A11）三态地址端管脚（悬空，接高电平，接低电平），任意组合可提供531441地址码，PT2262最多可有6位（D0-D5）数据端管脚，设定的地址码和数据码从17脚串行输出。PT2262/2272必须用相同地址码配对使用，当需要增加一个通讯机时，用户不得不求助于技术人员或厂家来设置相同地址码，客户自己设置相对比较麻烦，尤其对不懂电子的人来说。随着人们对操作的要求越来越高，PT2262/2272的这种配对使用严重制约着使用的方便性，人们不断地要求使用一种无须请教专业人士，无须使用特殊工具，任何人都可以操作的方便的手段来弥补PT2262/2272的缺陷，这就是PT2262软件解码。如果在接收端采用软件解码，则可节省单片机的I/O口和解码芯片PT2272，本方案适合单工无线传输，发射端无须单片机，硬件简单，性价比高。
