I kind of did not notice, but the summer has begun. We all did well surviving until now.
branding that goes hard: ERO-TANTAL for tantalum capacitors. what does it stand for? "erotically tantalizing"

O hai! It is #NakedDieFriday today, and despite my fiber still carrying no light, I think we can organize something.

Today's exhibit is one that should be familiar to the DIYers around. This is a chip that went into many a USB to serial doodads, the CH340 by WCH / WinChipHead. The chip looks rather unassuming, with a reasonably large CMOS 2-met process.

PSA: the fibre is lit! And infosecdj.net should be back in order as soon as the DNS changes propagate.
Woke up, but at what cost...
A close-up of the microcode ROM shows the individual bits. Unlike most ROMs, the 8087 uses four transistor sizes, letting it store two bits per transistor. This complex, semi-analog approach was necessary to fit all the data into the chip; the 8087 pushed the limits of 1980 technology. 3/n
