Deep Dive: This is what the chip of the Raspberry Pi Zero 2 W contains

The Raspberry Pi Zero 2 W has been well received by the maker community and is a welcome addition to the range of minicomputers, small, economical and finally no longer so lame. The Raspberry Pi Foundation itself published the specifications and performance data for the BCM2710A1 SoC used, including Eben Upton with an interesting video interview. The community carried out its own tests and benchmarks very quickly, and there will also be an article on this in Make 6/21 (to be published on December 9, 2021).

Many makers and Youtubers received test objects and data from the Zero 2 W in advance and, with the exception of a few small leaks, everything was published at the same time as the official release. However, this information was not enough for the user electronupdate, especially because a lot of internal information about the SoC is not published. The reason: The manufacturer of the SoC Broadcom obliges its customers to maintain secrecy about certain details and supplies proprietary, undisclosed software for certain functions of the SoC. This fact has long been a thorn in the side of the community.

Electronupdate has therefore taken the Raspi Zero 2 W in front of its chest and subjected it to an extreme teardown. Among other things, he dissected the SoC and examined it with a microscope. He has the knowledge gained as well as surprises and Easter eggs found on him Youtube and in his Blog released.
