The ATECC508A includes an EEPROM array which can be used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations. Access to the various sections of memory can be restricted in a variety of ways and then the configuration can be locked 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 1Mb/s. The interface is compatible with standard Serial EEPROM I The ATECC508A can generate high-quality FIPS random numbers and employ them for any purpose, including usage as part of the device's crypto protocols. Each random number is guaranteed to be essentially unique from all numbers ever generated on this or any other device, their inclusion in the protocol calculation ensures that replay attacks (i.e. re-transmitting a previously successful transaction) will always fail's interface specifications. The device also supports a Single-Wire Interface (SWI), which can reduce the number of GPIOs required on the system processor, and/or reduce the number of pins on connectors. If the Single-Wire Interface is enabled, the remaining pin is available for use as a GPIO, an authenticated output or tamper input. Using either the I2C or Single-Wire Interface, multiple ATECC508A devices can share the same bus, which saves processor GPIO usage in systems with multiple clients such as different color ink tanks or multiple spare parts, for example.
