5. Absolute Maximum Ratings

5.1 Absolute Maximum DC Ratings

Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only, and

functional operation of the device at these or any other conditions above those indicated in the operational sections of

this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

reliability.

NOTE 1 Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification

is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability

NOTE 2 See “Power-Ramp” section for relationships between power supplies.

NOTE 3 VREFDQ ≤ 0.6 x VDDQ; however, VREFDQ may be ≥ VDDQ provided that VREFDQ ≤ 300mV.

NOTE 4 VREFCA ≤ 0.6 x VDDCA; however, VREFCA may be ≥ VDDCA provided that VREFCA ≤ 300mV.

NOTE 5 Storage Temperature is the case surface temperature on the center/top side of the LPDDR2 device.

For the measurement conditions, please refer to JESD51-2 standard.
