ABRIDGED DATA SHEET EVALUATION KIT AVAILABLE DS28E25 DeepCover Secure Authenticator with 1-Wire SHA-256 and 4Kb User EEPROM General Description DeepCover™ embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The DeepCover Secure Authenticator (DS28E25) combines crypto-strong, bidirectional, secure challengeand-response authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). A 4Kb user-programmable EEPROM array provides nonvolatile storage of application data and additional protected memory holds a readprotected secret for SHA-256 operations and settings for user memory control.
