ATECC108 datasheet



The ATECC108 includes an EEPROM array that can be used for storage of up to 16 keys, miscellaneous read/write, read-only or secret data, consumption logging, and security configuration. Access to the various sections of memory can be restricted in a variety of ways and then the configuration locked to prevent changes.

ATECC108 features a wide array of defensive mechanisms specifically designed to prevent physical attacks on the device itself or logical attacks on the data transmitted between the device and the system. Hardware restrictions on the ways in which keys are used or generated provide further defense against certain styles of attack.
