Well, if you happen to have a Samsung Galaxy Tab, a high powered microscope, and the bravery to open your tablet down to its innards, then you'll be in for a treat. Inside the Galaxy Tab located on an Infineon chip is a message from the engineers. It's impossible to see with the naked eye (unless you have bionic vision), and you'll find a warning message from the chip engineers. Also, not only did they leave that message there for you to find, they've also included plenty of artwork on the chip including a man playing drums, a smiley face and a newly hatched chick.
chipworks.com - When tearing apart a recent Samsung Galaxy tablet, we came across an Infineon device that really set itself apart from the crowd. The featured device is Infineon’s PMB5703, which has had design wins in both the Galaxy phone and tablet (among others). This device is an impressive single chip, dual-mode RF transceiver IC, with integrated baseband functionality and 3G digRF standard interface. By making the digital part independent from the RF implememtation, it removes the need for an additional baseband IC.
