Project description:
The MintyMP3 hardware is a standard mix of high power 8-bit microcontroller and ASICs. A single PIC18LF452 running at 20mhz (For v2 the crystal has been changed to 29.4912MHz) with the minty firmware talks to the CF flash card, navigating the FAT16 file system and loading mp3 files, then sending the data to the STA013 MP3 decoder chip. The STA013 decodes MP3 into digital audio which is then converted to linelevel audio by the CS4340 DAC. There is also a MAX576 boost regulator (optional if running from a LiIon battery) and a MAX2606 FM transmitter (optional).

Electronics used:
STA013
CS4340 DAC
MAX576
MAX2606, FM transmitter
FTDI232BM
MAX1811
