This may run a little long, so please bear with me.  I have a 
reproduction of a Star Trek communicator prop that contains a chip to 
handle its limited functions and play back some recorded sound 
effects.  It's original Chinese maker recorded the sound effects 
poorly, and they're too loud and distorted.  I want to replace this 
chip with another that has properly-recorded effects.

The problem is that the chip (an Elan EM57P300AP) requires special 
programming hardware and software.  The chipmaker does not return 
inquiry emails and there does not seem to be an active U.S. 
representative for them.

So, I'd asked several people for ideas.  Almost all of them said "Use a 
PIC!" (The one that didn't suggested I use a hammer.)  After reading 
some literature I thought that was a great idea; the problem is that 
there doesn't seem to be a ready choice for a plug-in pin for pin 
substitute that can handle all the functions.  What's required is:

- Drive any of three LEDs depending on which switch is closed;
- Handle four switch inputs;
- Drive a tiny 3-volt motor;
- Play back three recorded sound effects (.wav files or similar) 
depending on which switch is closed.

Can anyone recommend a particular PIC that would handle these functions?
