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

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.
