Notes:
1. This parameter is characterized and is not 100% tested.
2. AC measurement conditions:
RL (connects to VCC): 1.3 kΩ (2.7V, 5V), 10 kΩ (1.8V)
Input pulse voltages: 0.3VCC to 0.7VCC
Input rise and fall times: ≤50 ns
Input and output timing reference voltages: 0.5VCC
3. The Write Cycle Time of 5 ms only applies to the AT24C512 devices bearing the process letter “A” on the package (the mark
is located in the lower right corner on the top side of the package).
