ELECTRICAL SPECIFICATIONS
Absolute Maximum DC Ratings
Notes:
1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to
3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must be not greater than 0.6 x VDDQ. When VDD and VDDQ and
4. Voltage on any input or I/O may not exceed voltage on VDDQ.
AC & DC Recommended Operating Conditions
Recommended DC Operating Conditions (SSTL-1.8)
Notes:
1. There is no specific device VDD supply voltage requirement for SSTL_18 compliance. However under all conditions VDDQ must be less than
2. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be
3. Peak to peak ac noise on VREF may not exceed +/-2 % VREF(dc).
4. VTT of transmitting device must track VREF of receiving device.
5. VDDQ tracks with VDD, VDDL tracks with VDD. AC parameters are measured with VDD, VDDQ and VDDDL tied together
