Electrical Specifications

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 maxi-

mum rating conditions for extended periods may affect reliability.

Notes:

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 reli-

ability

2. See “Power-Ramp” section in “Power-up, Initialization, and Power-Off” for relationships between power supplies.

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

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

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.
