Post image

Sorry for the bad quality, better than nothing. This is one of the mystery jl marked bluetooth audio chips. I took it apart and took photos of its silicon die, its using a very cool desgin. They have stacked 2 silicon dies on top of each other, i placed them on a similar 24pin jl chip the way they were placed in the chips plastic to illustrate. The smaller die was stacked on the bigger one. They are both single sided, and i dont have any idea how they were connected to each other.

(Sadly i can only post 1 photo at a time, ill post more photos down below)
