This MP3 player design takes ISP1362 as the USB Host, the single chip microcontroller AT89C51SND1 as the main controller and MP3 decoder. Thepaper introduces how to read and play MP3 files from U-disk directly in detail.

• 本文使用AT89C51SND1作为主控制器和MP3解码器,ISP1362作为USB主机,将U盘中的MP3文件读取出来并进行播放,实现了MP3播放器中解码单元与存储单元的分离。
