Sound chips

Subject: Music or Sound Synthesis ICs

I am starting to design the circuits used in clocks or some toys and gifts.
I need the information of the ICs or components that can generate or synthesize music or sound (CPU-controlled and programmable may not be suitable for this case, but I am not sure).

I bought some time ago several of those preprogrammed melody IC*'s from Radio Rotor. Manufacturer United Microelectronics Corp., type numbers start with UM....

United Microelectronics has a website (found thanks to the chipdir!)
www.umc.com.tw/

Radio Rotor has a website with a catalog on line.

Choose the IC* page and scroll down to the UM parts.
Of course there are many other suppliers.

Some Melody generator IC*'s in a TO-92 package are avalible from Digi-Key. They can be reached at www.digikey.com/ or 1-800-344-4539. They cost $ .81 in the March-April 1997 catalog {page 149}.

Subject: Holtek HT3810 series

Holtek manufactured a series of Melody Generators in a TO-92 package. I know they discontinued them. I checked their web site as well as Digikey and Digikey has a few left.
Would anyone know where someone may have a supply of these? My searching is coming up empty. I want to add melodies to special needs children's off-the-shelf adapted toys. Has everyone gone to this Chip-On-Board stuff? And, if so, does someone make a line of melodies like Holtek did using this technology?

As far as I remember Conrad here in Germany has some of these chips in their catalog.
You may also want to check www.conrad.com/ or www.conrad.de/ (I dont know exactly and dont have a actual catalogue available here :-(
