DC Characteristics and Operating Conditions (Vdd, VddQ = 2.5V ± 0.15V, Ta = 0~70×°C)

Notes : 1. These parameters depend on the cycle rate and these values are measured at a cycle rate with the minimum values of tCK, tRC and IRC.

2. These parameters depend on the output loading. The specified values are obtained with the output open.

3. Refer to output driver characteristics for the detail. Output Driver Strength is selected by Extended Mode Register.
