Note:
1. Under all conditions VDDQ must be less than or equal to VDD.
2. VDDQ tracks with VDD. AC parameters are measured with VDD and VDDQ tied together.
3. Maximun DC value may not be great than 1.425V.The DC value is the linear average of VDD/ VDDQ(t) over a very long period of time
(e.g., 1 sec).
4. If maximum limit is exceeded, input levels shall be governed by DDR3 specifications.
5. Under these supply voltages, the device operates to this DDR3L specification.
6. Once initialized for DDR3 operation, DDR3L operation may only be used if the device is in reset while VDD and VDDQ are changed
for DDR3L operation.
7. VDD= VDDQ= 1.35V (1.283–1.45V )
Backward compatible to VDD= VDDQ= 1.5V ±0.075V
Supports DDR3L devices to be backward com-patible in 1.5V applications
