Keywords:Internet radios  PIC18F67J60  MP3 audio decoder 

Internet radios are defined as a "hardware device that receives and plays audio from Internet radio stations or a user's PC". The audio is streamed to the radio using MPEG-1 audio layer 3, Windows Media Audio or Advanced Audio Coding compressed audio formats. The "radio stations" range anywhere from public AM or FM radio stations that broadcast over the air as well as on the Internet, to University radio stations down to any individual wishing to create their own radio station.

The focus of this application note by Microchip is to show how to create a low-cost Internet Radio that connects to SHOUTcast servers and plays MP3 audio. The hardware uses the PIC18F67J60 microcontroller with integrated 10Base-T MAC and PHY and an external MP3 audio decoder. The software uses the standard Microchip TCP/IP Stack with external serial SRAM buffering to ease the streaming of compressed audio data to the MP3 decoder.
