hi,


I'm looking for MP3 module ( DSP used in mp3 players) with those standard features : MP3 decoder, system controller for loading MP3 files from a USB flash drive, dictaphone and 1 or 2 GB memory.


and a with a low price cause I would like to buy it in large quantity.


I'll be thankful for everyone who will give me a reference of such mp3 module. :D

hi randel_xtian,


thank you for this clear mp3 diagram !! :D (i'll be very thankful if you bring other similar documents)

what is the price of the DSP that you use ? (I think it's over featured for my application)

what do you think of the DSP and other IC used in s1 mp3 palyers (like the ATJ2085) ?

for details, check this site : **broken link removed**





thanks in advance.

hi randell_xtian,

Thank you for this link, i took a look there and i think it's a good and economic project also, but may be a USB port and a Flash memory (Samsung or Hynix as in my link) would be better particularly for PC's without SD card port.

on the other, The ATJ2085 which is an audio "system on chip" (Inside, there is a Z80 processor) offers many features like Audio decoding, DSP, recording, interaces with Flash memory, headphone, microphone,....those features are found in separate IC (18LF452 and VS1001 (mp3 encoder/decoder) )in the project in your link above.



ATJ2085 is a single-chip for flash-based digital music player. It includes an audio decoder with a high performance DSP, ADPCM record capabilities and USB interface for downloading music and uploading voice recordings. ATJ2085 also provides an interface to flash memory, LED, button and switch inputs, headphone, and microphone, and FM radio input and control. ATJ2085’s programmable
architecture supports the MP3, WMA and other digital audio standards. For devices like USB-Disk, ATJ2085 can act as a USB mass storage slave device to personal
computer system. Its low power consumption allows a long battery life, and an efficient flexible on-chip DC-DC converter allows many different battery configurations, including 1xAA, 1xAAA, 2xAA, 2xAAA and Li-Ion. Built-in Sigma-Delta DAC & a headphone driver to directly drive low impedance headphones. The ADC includes inputs for both Microphone and Analog Audio in to support voice recording and FM radio integration features. Thus, the ATJ2085 provides a true ‘ALL-IN-ONE’ solution that is ideally suited for highly optimized digital audio players with mass storage function.
