Tolerance limits assume RZQ of 240��±1% and are applicable after proper ZQ calibration has been performed at a stable temperature and voltage (VDDQ = VDD; VSSQ = VSS). Refer to 40 Ohm Output Driver Sensitivity (page 65) if either the temperature or the voltage changes after calibration. 2. Measurement definition for mismatch between pull-up and pull-down (MMPUPD). Measure both RON(PU) and RON(PD) at 0.5 × VDDQ: RON(PU) - RON(PD) MMPUPD = × 100 RON,nom 40 Ohm Output Driver Sensitivity 3. For IT and AT (1Gb only) devices, the minimum values are derated by 6% when the device operates between –40°C and 0°C (T C). If either the temperature or the voltage changes after I/O calibration, then the tolerance limits listed in Table 45 can be expected to widen according to Table 46 and Table 47 (page 66).
