iPhone CPU exposed

iPhone Circuits iPhone CPU Chips

As promised, thanks to the guys at Think Secret, I have started imaging the chips inside the Apple iPhone. I started out with the processor and can confirm that the chip contains both the ARM CPU and the RAM, three dies to be exact. Unfortunately, there was not much to look at under the microscope. The CPU had what looked to be a model number and the RAM chips had what looked to be part of a model number on the cut-away part of the die. No visible logos or slogans on these chips. It was plus unlucky that the chips had a layer of metal on top which prevented me from seeing




most of the actual circuitry. The only marginally interesting part was that under 100x magnification, it seemed that some of the perforations in the metal on the CPU may have been letters instead of square holes. You can judge for yourself.

In any case, I removed all of the chips from the iPhone using a hot plate so feel free to propose the next chip for imaging in the comments. The FLASH was removed separately using Chipquick and will be saved for potential reading. Below are scans (~4MB each) of the two logic boards to help you assemble the selection.
