3. The Write Cycle Time of 5 ms only applies to the AT24C128/256 devices bearing the process letter “B” on the package (the
mark is located in the lower right corner on the top side of the package).
4. The AT24C128/256 bearing the process letter “B” in the package (the mark is located in the lower right corner on the top
side of the package), guarantees 1 million write cycle endurance (1.8 – 3.6V).
