It’s a #silicondoodle !

What followed my „easter egg hunter“ post was a request for an interview by the National Public Radio (NPR)… and today, the article about the topic was published! Enjoy reading!

It´s a 8080!
I also stitched 70 microscopy pictures to one picture...beautiful transistors...

It´s an 8080!
I did not dare decapping the original Intel 8080 but some time ago, I opened a NEC version - the D8080AF from 1976. How do you like the macro shot?

It’s an #Intel 8080!
50 years ago, to this date, Intel launched the 8bit 8080 CPU. 🥳
Anyone has any good memories using this processor?

Looks like a great moment!

It´s an #Intel #486DX !
35 years ago to this date, Intel announced its second 32-bit processor called the i486!
I made a small video highlighting some feaures about this milestone in #CPU history!
Enjoy!

Sneak preview

It’s a #cartwheeler ! 🤸‍♀️
The largest chip used in the S4 is a #Siemens PMB 2705 which is a GOLD - GSM One-chip Logic Device. The #IC contains a hidden Easter egg in the form of a cartwheeler.
Siemens (now Infineon) had one of its regional headquarters in the German city Düsseldorf

It’s a #Siemens S4 mobile phone!
Only one of the four Siemens ICs has a #silicondoodle . You recognise it on the broken IC?
The memory ICs are also ‚empty‘.
The second doodle (the hatching dino) is on the #AnalogDevices Mixed Signal processor which takes the function of speech

It’s an #EasterEgg !
Those vintage mobile phones have many ICs…the S4 from Siemens (1995) counts 7. Two of the chips have an #easteregg hidden inside.
Watch my video to find them!

Nutritional Yeast Infection 🌱 Druthers Haver Y'all joking but there really is a tradition of printed circuit board Easter eggs.

Yes and I am one of these Easter egg hunters…

#HappyEaster !
If you wonder in which device I found the hetching 🦖, have a look at the video I posted!
There is also an Easter egg hidden in the video…will you find it?

It’s a #HetchingDino !
Do you know why epoxy is such a great material for encapsulating #silicon #chips ? There must be many reasons but I find it amazing when a #die is decapped and the epoxy mold shows all fine details of the silicon…just mirrored… 🪞

It’s a #HetchingDino ! 🦖
The Easter 🐣 weekend is near and I found my easter egg already!
It was hidden on an #AnalogDevices chip, namely the ADSP-21MSP59.
Where do you think that chip is used? Small hint: it is a Mixed Signal Processor…guess the application! 1/n

How a well placed light source can make an awesome „glowing pcb“ picture 🤩

It‘s a #mobile !
What powers mobile phones? I guess it is these kind of integrated circuits like the IC i76502 made by #DialogSemiconductor (now part of Renesas)…Why would otherwise this cute #silicondoodle be placed on that chip if not for a mobile application?
Dialog was a

Very interesting, later released #AMD #Athlon Thunderbirds, have a new revision of the top metal layer (the previous top metal layers were made of aluminum).
