Good question..

Here's the datasheet for those interested: 

 From a DIY perspective, the package on this is very small so it makes 
me think that it was designed with some OEM manufacturers in mind that 
probably already use certain SSI chips in their designs.

I'd also imagine this could be use in synths without boasting any TZ 
function.. it seems like a solid little chip for a VCO even if TZ isn't 

For anyone that wants to mess around with the 2130, I see Evaluation 
Boards are also available:
