+ The datasheet of the Atmega328p chip does not say anything about the serial number, but I tested using the same Z-pointer Address on the datasheet of the Atmega328pb.
+ Apparently, the chip Atmega328p have a hidden serial number with 9 bytes, and others AVR Microcontroller maybe too, like the table below.
