I've tried searching online for the chip(s) used in current consumer  
digital alarm clocks.  Most references I've found refer to long  
obsolete chip numbers from the MM531x series or other obsolete chips  
such as the MM5387.  I have a small quantity of these older chips, but  
I have plans for a project that may exceed my inventory.  While I  
could utilize a PIC, I think it's rather unlikely that mass-produced  
clocks selling for under $10 use a microcontroller.  I'm thinking  
there must be a National number for a clock chip in current production  
I'm unaware of.

Thanks

Joe
