ABRIDGED DATA SHEET DS28EL15 DeepCover Secure Authenticator with 1-Wire SHA-256 and 512-Bit User EEPROM General Description DeepCoverK embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the industry’s most secure key storage possible. The Deepcover Secure Authenticator (DS28EL15) combines crypto-strong bidirectional secure challenge-and-response authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). A 512-bit userprogrammable 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.
