• Manufacturer Part Number: ds2764aet-r
• Description: Ds2764 High-precision Li+ Battery Monitor With 2-wire Interface
• Manufacturer: Maxim Integrated Products, Inc.

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.
