ABSOLUTE MAXIMUM RATINGS

Stresses at or above those listed in Table 36 may cause perma-

nent damage to the product. This is a stress rating only;

functional operation of the product at these or any other condi-

tions above those indicated in the operational section of this

specification is not implied. Operation beyond the maximum

operating conditions for extended periods may affect product

reliability.

DDR3 Input Voltage1

1 Applies only when the related power supply (VDD_DMC or VDD_EXT) is within

specification. When the power supply is below specification, the range is the

voltage being applied to that power domain ± 0.2 V.

4 Applies only when VDD_ANA is within specifications and ≤ 1.8 V. When VDD_ANA

is within specifications and > 1.8 V, the maximum rating is 1.89 V. When

VDD_ANA is below specifications, the range is VDD_ANA ± 0.09 V.

1 The individual values cannot be combined for analysis of a single instance of

overshoot or undershoot. The worst case observed value must fall within one of

the voltages specified and the total duration of the overshoot or undershoot

(exceeding the 100% case) must be less than or equal to the corresponding duty

cycle.

2 Duty cycle refers to the percentage of time the signal exceeds the value for the

100% case. This is equivalent to the measured duration of a single instance of

overshoot or undershoot as a percentage of the period of occurrence.

ESD (electrostatic discharge) sensitive device.

Charged devices and circuit boards can discharge

without detection. Although this product features

patented or proprietary protection circuitry, damage

may occur on devices subjected to high energy ESD.

Therefore, proper ESD precautions should be taken to

avoid performance degradation or loss of functionality.
