Evidence

https://en.wikipedia.org/wiki/Nintendo_S-SMP#DSP All of the functional and descriptive information is listed on this Wikipedia page. As for the assembly location, I did some digging on Sony's websites and found that the Inazawa plant is where most of their chips are produced. I could not find any earlier plants, so I am making the inference that this was also the plant in use during the late 1980's and early 1990's. As for the manufacturing date, I assume it's 1992 because that is when most of the date codes on other parts are listed.
