Pin Name Description
Absolute maximum voltages are with respect to GND. 1 SDA Serial data I/O 2 CP Positive capacitance node Absolute maximum electrical ratings are over the 3 CN Negative capacitance node operating temperature range. 4 VDD Power supply Absolute Maximum Ratings are stress ratings. Stresses in 5 GND Ground excess of these ratings can cause permanent damage to 6 SCL Serial clock input the device. Functional operation of the device at conditions beyond those indicated in the operational sections of this data sheet is not implied.

Supply voltage VDD 2.5 3.3 5.5 V Capacitor voltage, CP or CN to GND 1, 2 VDD < 3.3V V V DD + 0.3 CP, VCN -0.3 - VPK VDD > 3.3V 3.6 Non-Volatile Write Programming time 3 tPNV - 5 - ms Operating temperature TA -40 - +105 °C 1 VPK=VDC+VAC is the voltage applied to capacitor pins CP and CN. It should never exceed 3.6V in operation, and should never be less than -0.3V. Sufficient DC bias must be applied to the capacitor pins to prevent the AC signal from violating this specification. Pins CP and CN are not self biased. 2 These maximum values not to exceed the supply voltage; e.g. the maximum voltage drop between CN and GND is 2.8V when VDD=2.5V. 3 There are three erase commands and three non-volatile write commands to program the Non-Volatile Register. This time is for each of the three non-volatile write commands, not the sum of all three commands. The timing requirement also applies to each of the three erase commands, not the sum of all three.
