DS28E25+ Product Details
The DS28E25+ is a DeepCover secure authenticator with 1-wire SHA-256 and 4Kb user EEPROM in 2 pin TO-92 package. The DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide most secure key storage possible. The DeepCover secure authenticator (DS28E25) 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 4Kb user-programmable EEPROM array provides non-volatile storage of application data and additional protected memory holds a read protected secret for SHA-256 operations and settings for user memory control. It has its own unique 64bit ROM identification number (ROM ID) that is factory programmed into the chip. It is used in authentication of network-attached appliances, printer cartridge ID/authentication, reference design license management and system intellectual property protection.
