I suppose, why not...depends on where and in what format the file is stored.

If all you have to do is pick up the bytes from a wav/other file and output it to a DAC + Power Amplifier, there should be no problem since even at f/12 a clock speed of 4 Mhz should be more than enough (assuming the output freq is around the usual 20 kHz range).

The problem would be where to store this huge data...and how to access it fast enough. If it is a wave file, you will have to decode all the RIFF chunks before you play,and that, i guess, may also require a lot of RAM.

Another (small) problem is that 8052 is an 8-bit device...whereas the resolution required for ur music file maybe 16-bit or more. You will have to use multiple mov commands.

Can't say anything about the ASIC tho' ... seems difficult
