DS28E15 ABRIDGED DATA SHEET DeepCover Secure Authenticator with 1-Wire SHA-256 and 512-Bit 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 (DS28E15) combines crypto-strong bidirectional secure challenge-andresponse authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). A 512-bit user-programmable EEPROM array provides nonvolatile storage of application data. Additional protected memory holds a read-protected secret for SHA-256 operations and settings for memory protection control.
