提出一種基于單片機(jī)AT89C51SND1C的MP3播放系統(tǒng)的設(shè)計方案。單片機(jī)集成了專用的解碼器，使用K9F1208閃存作為外存儲器，放音電路采用CS4330，存儲文件通過播放器上的USB接口設(shè)備從PC機(jī)上直接下載，液晶顯示采用LCD1602。方案設(shè)計簡單，性價比高，低功耗，易擴(kuò)展。由于采用的是通用單片機(jī)實現(xiàn)的，可以很容易地移植到其他微控制器系統(tǒng)中，有很強(qiáng)的市場競爭能力和實用價值。
Abstract:
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.
