8V Operation General Description The DS28E02 combines 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 communicates over the single-contact 1-Wire® bus.
The communication follows the standard 1-Wire protocol with the registration number acting as the node address in the case of a multidevice 1-Wire network.
