DS28E02 Datasheet | Maxim Integrated

ABRIDGED DATA SHEET Rev 0: 6/10 .. 1-Wire SHA-1 Authenticated 1Kb EEPROM with 1.8V Operation General Description The DS28E02 bines 1024 bits of EEPROM with challenge-and-response authentication security implemented with the FIPS 180-3 Secure Hash Algorithm (SHA-1). The 1024-bit EEPROM array is configured as four pages of 256 bits with a 64-bit scratchpad to perform write operations. All memory pages can be write protected, and one page can be put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. Each DS28E02 has its own guaranteed unique 64-bit ROM registration number that is factory installed into the chip. The DS28E02 municates over...
