Product Overview

ATECC608A-SSHDA-B is a CryptoAuthentication™ device. It is a Cryptographic co-processor with secure hardware-based key storage which has protected storage for up to 16 keys, certificates, or data. It 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 1Mb/s. The interface is compatible with standard serial EEPROM I2C interface specifications. Typical applications are IoT network endpoint key management and exchange, encryption for small messages and PII data, secure boot and protected download, ecosystem control, and anti-cloning.
  • Internal high-quality NIST SP 800-90A/B/C random number generator (RNG)
  • Two high-endurance monotonic counters, unique 72-bit serial number
  • 1.8V to 5.5V IO levels, 2.0V to 5.5V supply voltage
  • 150nA sleep current
  • Secure boot function, with IO encryption and authentication
  • GFM calculation function for GCM AEAD mode of AES
  • Volatile key permitting to prevent device transfer, counter limit match function
  • Transport key locking to protect programmed devices during delivery
  • Unaligned public key for built-in X.509 cert key validation
  • Operating temperature range from -40°C to +85°C, 8-lead SOIC package
