Engineers are used to learning from examples. John @johndmcmaster helps to provide these examples. Check out his presentation about decapping and imaging ICs at open tape-out conference

The HP 3458A (1988) is a super-accurate 8½-digit multimeter. There's an unusual hybrid current-steering chip at the heart of it that performs the high-resolution analog-to-digital conversion. I'm helping to reverse-engineer this chip.

Sega Saturn 315-5933 (1995) The Sega Saturn DRAM controller is implemented on a NEC 1µm channelless CMOS-6X family µPD65626 gate array. With 5,760 gates for 4,033 maximum useable gates, all the empty space shows that Sega only used some of the available logic.

What would you title this work of art? 🤔 This silicon doodle was found in a @tektronix "peak detector" hybrid circuit module from inside a 2400 series oscilloscope. Part Number 165-1215-01. #oscilloscope #silicondoodle

Finally got my new microscope set up. My IC decapping and imaging technique can use some improvement, but I am excited for the cool stuff I am going to be able to see! In the coming months I am hoping to image some power ICs.

It's not one, but three different revision of the Z80 microprocessor today! Spot the differences between 1 gigapixels images of the dies on @johndmcmaster's Siliconpr0n. Links to follow in this thread. #Zilog #Z80 #retrocomputing #microprocessor

Thomson SFC2741 (1975) It's a classic, the 741 operational amplifier! You probably have used it, but maybe not in its original TO-99 metal package. A 121 megapixels image is available on @johndmcmaster's siliconpr0n. siliconpr0n.org/map/thomson/…

A closer look at yesterday's device, the Dallas Semiconductor DS1620. Dallas does like to sprinkle artwork on their designs!

Final cover art for "Hardware Hacking Handbook", now featuring news of @joegrand's forward and getting back to capture @jzvw's vision of showing that hardware hacking is an adventure. If nothing else about the book I love this new cover art.
