General Description
The DS28E10 combines 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 guaran teed unique 64-bit ROM identification number (ROM ID)
that is factory programmed into the chip. Memory writes
