Capacitance*
TA = 0 to 70°C, VCC = 2.5V ± 0.2V, VCC = 2.6V ± 0.1V
for DDR400, f = 1 Mhz
*Note: Capacitance is sampled and not 100% tested.
Absolute Maximum Ratings*
Operating temperature range ..................0 to 70 °C
Storage temperature range ................-55 to 150 °C
VDDSupply Voltage Relative to VSS.....-1V to +3.6V
VDDQ Supply Voltage Relative to VSS
......................................................-1V to +3.6V
VREF and Inputs Voltage Relative to VSS
......................................................-1V to +3.6V
I/O Pins Voltage Relative to VSS
..........................................-0.5V to VDDQ+0.5V
Power dissipation .......................................... 1.6 W
Data out current (short circuit) ...................... 50 mA
*Note: Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage of the device.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
