Hardware Identification System

All Xplained Pro compatible extension boards have an ATSHA204A CryptoAuthentication chip mounted.
This chip contains information that identifies the extension with its name and some extra data. When an
Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and sent to
Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code
examples, and links to relevant documents. The table below shows the data fields stored in the ID chip
with example content.
