Greetings. This is #nakeddiefriday and today I got one on a reader's request.

I was kindly provided with the ASIC chip from the new #Lego Smart Brick. It is the one marked DA000001-04, which nobody really knows what it is and who made it. There were suggestions it was made by Dialog but no solid evidence AFAIK.

The first image is with the die intact. You can see a ball pad array on the redistribution layer. RDL is made from polyimide with copper traces, not unlike flex PCBs. It is bonded to the silicon die pads on the perimeter. Unfortunately, RDL considerably obscures the die.

Pre-flight checks complete, taking off.

@nixCraft so it's not because Linux got any better, it's because competition got much worse, do I read this right?

@GossiTheDog but you need to PAY them EVERY MONTH! how obscene

hardly anything is a bigger red flag in security than "we make our code secure by restricting access to it." most of all, the startup code in ROM.

@mcc try not to pay to quickly find out why~~

In today's #nakeddiefriday we have YM3012, a 2-channel serial DAC used together with YM2151 OPM chip.

These came in blacktopped, so some forensics was in order. :-)

@gnu2 Yeah I feel this way of thinking is how we got where we're now at.
