DS2764K Maxim Integrated, DS2764K Datasheet - Page 11

• Manufacturer Part Number: DS2764K
• Description: Power Management IC Development Tools
• Manufacturer: Maxim Integrated
• Series: DS2764r

into the information fields of the Device Setup, Battery Data, and Fuel Gauging Data sub-tabs. To change
any of this information, simply click on the desired text field and enter the new value. Once all data is in
the desired format, click on the Write DS2764 button to copy it to the EEPROM of the DS2764. This
information can also be stored to a file and recalled later using the Load/Save Pack Info buttons.
The memory map above shows the format in which the data is stored within the device. All static data is
stored in Block 1 while data which might need to be updated is in Block 0. The pack manufacturer can
now permanently lock Block 1 to maintain data integrity while leaving Block 0 open for access by the
host processor.
