Most silicon vendors have an end-of-life (EOL) policy.  The general idea, at 
least for the ones I'm familiar with, is that they will announce the end of 
life of a product and take orders until some date and promise to fill all 
those orders.

Distributors often send the end-of-life notices on to customers who have 
ordered those parts.  That can be wonderful or spam depending on your 
mood/circumstances.

Things get more complicated if you are a board-level vendor and a chip you 
use goes EOL.  If you are shipping X parts per year and you depend on a chip 
that goes EOL and costs $Y, you can figure out how many you should order to 
cover the next N years.  That assumes that your order predictions are correct 
and also that the chips you receive work as expected.  Things get ugly if the 
chips you ordered and stockpiled don't work as expected.
