5 / 22 page 5 AT24C512 1116O–SEEPR–1/07 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). Table 4. AC Characteristics Applicable over recommended operating range from TA = –40°C to +85°C, VCC = +1.8V to +5.5V, CL = 100 pF (unless oth- erwise noted) Test conditions are listed in Note 2.
