Notes:
1. This parameter is characterized and is not 100% tested.
2. AC measurement conditions:
R L (connects to V CC ): 1.3 k Ω (2.5V, 5V), 10 k Ω (1.8V)
Input pulse voltages: 0.3 V CC to 0.7 V CC
Input rise and fall times: ≤ 50 ns
Input and output timing reference voltages: 0.5 V CC
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).
