DS28E10 Datasheet | Maxim Integrated

Description The DS28E10 bines secure challenge-and-response authentication functionality based on the FIPS 180-3 specified Secure Hash Algorithm (SHA-1) with 224 bits of one-time programmable user EPROM in a single chip. Once written, the memory is automatically write protected. Additionally, each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. Memory writes are performed 4 bytes at a time. A secure and low-cost factory programming service is available to preprogram device data, including the SHA-1 security data ponents. The device municates over the single-contact 1-Wire® bus. The munication follows the standard 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.
