Re: 2021, time for a new general & diff speculation thread...
So, for the s17 chip (bm1397AD), package dimensions are 8x8 mm, die looks like about 5mm x 5mm. Still seems like a lot of wafer real estate for a chip you can buy for $6. S19 chips are going for about $25.
mmm 25 a chip and 800 or so a wafer is 20 k a wafer
