single chip music player

I am trying to help a friend find a chip that I suspect doesn't exist but I have to give it a try. He wants a simple circuit that will play a single song when a button is pressed (I have no idea why). I have found a few voice recorder type chips that will do it that simply but they don't have enough run time and the sound quality is low. Other than that all I have found requires some kind of microprocessor and often even a separate flash memory interface. Which all seems over kill way to complex for the the stated purpose. Anyone know of any thing that will fit the bill?

Look at the UM66. It can play simple melodies like "happy birthday", it's used in greeting cards and such. It comes in a T092 packages and can drive directly a piezo transducer or a speaker with a transistor.

there are available music chips that have factory programmed tunes in them. Greensleeves, merry christmas, etc...

But if you want to chose the tune yourself you need a microprocessor of some sort. I found that 2K of rom was suffuicient.

most small micros have a PWM output that can be used if you don't want to go to the effort of making an R-2R divider for the DAC...

here's one I prepared earlier :)

Look at some of the ISD chips
