They have foundries in many places around the world. The funny part with most of our American company is that to same money they have moved the production outside to low cost labor countries. NEC has build big in the USA and move some production here.

They still provide you with 4 bits or 8 bits devices if you need them even when the parts no longer officially exist. If you have a design with their devices they will provide you with parts as long as you are willing to pay for them.
This is very important for us for military and automotive designs because they doesn't want any change when a product works. Companies bad for pulling parts of the market are Freescale and Hitachi (now Renesas). NEC and ST are two companies who have made serious profits last year while companies like NXP, Infineon and Freescale have huge debts.
