DS28E22Q規(guī)格書詳情
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 serial number within the application.
Features
? Symmetric Key-Based Bidirectional Secure Authentication Model Based on SHA-256
? Dedicated Hardware-Accelerated SHA Engine for Generating SHA-256 MACs
? Strong Authentication with a High Bit Count, UserProgrammable Secret, and Input Challenge
? 2048 Bits of User EEPROM Partitioned Into 8 Pages of 256 Bits
? User-Programmable and Irreversible EEPROM Protection Modes Including Authentication, Write and Read Protect, and OTP/EPROM Emulation
? Unique, Factory-Programmed 64-Bit Identification Number
? Single-Contact 1-Wire Interface Communicates with Host at Up to 76.9kbps
? Operating Range: 3.3V ±10, -40°C to +85°C
? Low-Power 5μA (typ) Standby
? ±8kV Human Body Model ESD Protection (typ)
? 6-Pin TDFN, 6-Lead TSOC Packages
Applications
??? Authentication of Network-Attached Appliances
??? Printer Cartridge ID/Authentication
??? Reference Design License Management
??? System Intellectual Property Protection
??? Sensor/Accessory Authentication and Calibration
??? Secure Feature Setting for Configurable Systems
??? Key Generation and Exchange for Cryptographic Systems
