Overview

ABRIDGED DATA SHEET EVALUATION KIT AVAILABLE DS28E22 DeepCover Secure Authenticator with 1-Wire SHA-256 and 2Kb User EEPROM General Description DeepCoverM 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 (DS28E22) 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 2Kb 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.
Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip.
This unique ROM ID is used as a fundamental input parameter for cryptographic operations and also serves as an electronic seria...
