*Stresses at or 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 operation section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods will affect reliability. Refer to page 17 of this datasheet for a technical note on this subject. ** Junction temperature depends upon package type, cycle time, loading, ambient temperature and airflow, and humidity.

Output Driver ImpedanceThe output driver impedance is selected by MR1[5,1] during initialization. The selected value is able to maintain the tight tolerances specified if proper ZQ calibration is per-formed. Output specifications refer to the default output driver unless specifically sta-ted otherwise. A functional representation of the output buffer is shown below. The out-put driver impedance R ON is defined by the value of the external reference resistor RZQ as follows:•R ON,x = RZQ /y (with RZQ = 240ȍ ±1%; x = 34ȍ or 40ȍ with y = 7 or 6, respectively)The individual pull-up and pull-down resistors R ON(PU) and R ON(PD) are defined as fol-lows:•R ON(PU) = (V DDQ - V OUT )/|I OUT |, when R ON(PD) is turned off•R ON(PD) = (V OUT )/|I OUT |, when R ON(PU) is turned offFigure 28: Output DriverOutput driverChip in drive modeV DDQV SSQV OUTDQ34 Ohm Output Driver ImpedanceThe 34ȍ driver (MR1[5, 1] = 01) is the default driver. Unless otherwise stated, all timings and specifications listed herein apply to the 34ȍ driver only. Its impedance R ON is de-fined by the value of the external reference resistor RZQ as follows: R ON34 = RZQ/7 (with nominal RZQ = 240ȍ ±1%) and is actually 34.3ȍ ±1%.Table 38: DDR3L 34 Ohm Driver Impedance CharacteristicsNotes: 1.Tolerance limits assume RZQ of 240˖ ±1% and are applicable after proper ZQ calibra-tion has been performed at a stable temperature and voltage: V DDQ = V DD ; V SSQ = V SS ).Refer to DDR3L 34 Ohm Output Driver Sensitivity (page 69) if either the temperature or the voltage changes after calibration.2.Measurement definition for mismatch between pull-up and pull-down (MM PUPD ). Meas-ure both R ON(PU) and R ON(PD) at 0.5 × V DDQ :MM PUPD = ×100R ON(PU) - R ON(PD)R ON,nom3.For IT and AT devices, the minimum values are derated by 6% when the device operates between –40°C and 0°C (T C ).A larger maximum limit will result in slightly lower minimum currents.DDR3L 34 Ohm DriverUsing Table 39, the 34ȍ driver’s current range has been calculated and summarized in Table 40 (page 68) V DD = 1.35V , Table 41 for V DD = 1.45V , and Table 42 (page 69) for V DD = 1.283V . The individual pull-up and pull-down resistors R ON34(PD) and R ON34(PU)are defined as follows:•R ON34(PD) = (V OUT )/|I OUT |; R ON34(PU) is turned off•R ON34(PU) = (V DDQ - V OUT )/|I OUT |; R ON34(PD) is turned offTable 39: DDR3L 34 Ohm Driver Pull-Up and Pull-Down Impedance CalculationsTable 40: DDR3L 34 Ohm Driver I OH /I OL Characteristics: V DD = V DDQ = DDR3L@1.35VTable 41: DDR3L 34 Ohm Driver I OH /I OL Characteristics: V DD = V DDQ = DDR3L@1.45V 4Gb: x4, x8, x16 DDR3L SDRAM Output Driver Impedance。
