    I am going to design motion activated solar powered mp3 player. So my 1st task is design mp3 player.
    I looked and bought one that was 2.5usd, it has used only one IC.
    attached image.
    I checked the IC and read it and searched in google. But I couldn't find datasheet or schematic.

    anyone know one chip that has this functions.
    1.mp3 decorder
    2.USB
    3.sd card connections
    4. button connections for PLay,pause , vol+,vol-
    5. earphone output

    attached image is the pcb of my mp3 player, that chip has all of this[​IMG]

    I don't think there is a shortage of MP3 chip options. Did you Google "MP3 IC" or similar?

    Looks like Atmel has some but I'm sure they are not alone.

    You have the MP3 player so why design one?
