A few customer-specific products based on the SpringCore architecture feature a Microchip ATECC132A. It is used only to store HostCommAdminKey and HostCommUserKey, and to run the authentication with the host.
On the factory tools may access to the ATAES directly, while the device is still in manufacturing stage. Please use only the CHANGE KEY instruction to manipulate the content of the ATAES Secure Element afterwards.
