CryptoAuthentication™ ATECC508A: Crypto Element with ECDH and ECDSA

PublishTime：2021-10-28

The Atmel® ATECC508A Crypto Element device with hardware-based key storage supports ECDH (elliptic-curve Diffie-Hellman) operation to provide key-agreement function. The ATECC508A is the second device with advanced elliptic-curve (ECC) capabilities in the Atmel CryptoAuthentication™ portfolio.
● Key Features:
■ Optimized key storage and authentication
■ ECDH operation using stored private key
■ ECC-key generation
■ ECDSA (elliptic-curve digital signature algorithm) Sign-Verify
■ Support for X.509 certificate formats
■ 256-bit SHA/HMAC (secure hash algorithm/hash-based message authentication code) hardware engine
■ Multilevel RNG (random number generator) using FIPS (Federal Information Processing Standard) SP 800-90A DRBG (deterministic random-bit generator)
■ Guaranteed 72-bit unique ID
■ I2C and single-wire interfaces
■ 2 to 5.5V operation, 150-nA standby current
■ 10.5-kbit EEPROM for secret and private keys
■ Configuration ability for secret and private keys or data
■ Ability for eight slots to store public keys, signatures, or certificates
■ High Endurance Monotonic Counters
■ UDFN, SOIC, and 3-lead contact packages
