the random pin that goes in the mostly empty ring isn’t even used lol, why’d they put that there, why are they all placed like that, who did this
integrated circuit architecture engineers when they see a neatly formatted and space efficient BGA (it’s unacceptable):
tf is the point of all those pins if they aren't gonna be used 
this is an emmc correct?
FEMDNN004G-58A42 NAND 4GB eMMC flash memory chip, yeah
it looks strangely like a QFN package sized chip that someone put in a fullsize BGA package
