°C ≤ T
C ≤ 70 °C (comm.); -25°C ≤ TC ≤ 85 °C (ext.); VDD = 1.70 V - 1.95 V, VDDQ = 1.70 V - 1.95 V.Recommended Operating Conditions
unless otherwise noted
2) IDD specifications are tested after the device is properly initialized and measured at 133 MHz for -7.5 speed grade, and 166 MHz for -6
speed grade.
3) Input slew rate is 1.0 V/ns.
4) Definitions for
I
DD:LOW is defined as VIN ≤ 0.1 * VDDQ;HIGH is defined as VIN ≥ 0.9 * VDDQ;STABLE is defined as inputs stable at a
HIGH or LOW level;SWITCHING is defined as:- address and command: inputs changing between HIGH and LOW once per two clock
cycles;- data bus inputs: DQ changing between HIGH and LOW once per clock cycle; DM and DQS are STABLE
5) All parameters are measured with no output loads.
6) Value shown as typical and measured at 25
°C.
