ATECC608A

Description

The ATECC608A 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.
Access to the device is made through a standard I2C Interface at speeds of up to 1 Mb/s. The interface is compatible with standard Serial EEPROM I2C 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.
