AH01 - SHA-256 Hardware Encryption

This xChip is a core encryption module which forms part of the Crypto module range, running a security algorithm based on SHA-256.

This xChip includes the ATECC508A from Atmel, which is a secure CryptoAuthentication device, which is equipped with an EEPROM array that can be used for storing of up to 16 key, certificates, consumption logging, security configurations and other types of secure data. Access to the various sections of memory can be restricted in several different ways and then the configuration can be locked permanently, to prevent changes.

The ATECC508A features a wide array of defense 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.

Access to the device is made through a standard I2C interface at speeds of up to 1 Mb/s.
