摘　　要：提出一种基于单片机AT89C51SND1C的MP3播放系统的设计方案。单片机集成了专用的解码器,使用K9F1208闪存作为外存储器,放音电路采用CS4330,存储文件通过播放器上的USB接口设备从PC机上直接下载,液晶显示采用LCD1602。方案设计简单,性价比高,低功耗,易扩展。由于采用的是通用单片机实现的,可以很容易地移植到其他微控制器系统中,有很强的市场竞争能力和实用价值。A MP3 player design based on microchip AT89C51SND1C was presented, which used K9F1208 Flash chip as the memory circuit and used CS4330 as play chip. Storage files were download from PC through USB interfaces player on the device, and the LCD/602 was used as display screen. This system had characteristics of simple design,low power,easy expand, low cost and high recognition. Using of universual microchip make it easy to transplant to other microcontrol system,and have strong market competitiom and practical value.
