AT24C128/256
0670T–SEEPR–3/07
Table 4. AC Characteristics – Industrial Temperatures
Notes:
1. This parameter is characterized and is not 100% tested.
2. AC measurement conditions:
R
L (connects to VCC): 1.3 kΩ (2.5V, 5V), 10 kΩ (1.8V)
Input pulse voltages: 0.3 V
CC to 0.7 VCC
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).
Applicable over recommended operating range from T
AI = –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.
