64-BIT UNIQUE ID

The DS2764 can be special ordered with a unique, factory-programmed ID that is 64 bits in length. The first eight

bits are the product family code (B0h for DS2764). The next 48 bits are a unique 40-bit serial number followed by

0x64h. The last eight bits are a cyclic redundancy check (CRC) of the first 56 bits (see Figure 16). The 64-bit ID

can be read as 8 bytes starting at memory address F0h. The 64-bit ID is read only.
