Evidence

https://emu-docs.org/Genesis/Datasheets/5p832.pdf This is a datasheet for an identical chip from an earlier generation of SNES. As for the location of the assembly plant, it has been closed down and I am technically inferring that this was the plant used; I looked up what plants were active in the late '80's and early '90's and found that the Semiconductor plant in Japan was located in Sendai.
