The DS28E25 combines crypto-strong, bidirecTIonal,secure challenge-and-response authenTIcaTIon funcTIonalitywith an implementation based on the FIPS180-3-specified Secure Hash Algorithm (SHA-256). A4Kb user-programmable EEPROM array provides nonvolatilestorage of application data and additional protectedmemory holds a read-protected secret for SHA-256 operations and settings for user memory control.Each device has its own guaranteed unique 64-bitROM identification number (ROM ID) that is factory programmedinto the chip.
