Notes:
1. Thermal Impedance data is based on a number of of samples from mulitple lots and should be viewed as a typical number.
2. Please refer to JEDEC standard JESD51-6.
3. The characteristics of the test fixture PCB influence reported thermal characteristics of the device. Be advised that a good thermal path to
the PCB can result in cooling or heating of the RAM depending on PCB temperature.

Notes:
1. Compatible with both 1.8 V and 1.5 V I/O drivers.
2. These are DC test criteria. DC design criteria is V_REF ± 50 mV. The AC V_IH/V_IL levels are defined separately for measuring timing
parameters.
3. V_IL (Min)DC = –0.3 V, V_IL(Min)AC = –1.5 V (pulse width 3 ns).
4. V_IH (Max)DC = V_DDQ + 0.3 V, V_IH(Max)AC = V_DDQ + 0.85 V (pulse width 3 ns).

Notes:
1. The peak-to-peak AC component superimposed on V_REF may not exceed 5% of the DC component of V_REF.
2. To guarantee AC characteristics, V_IH,V_IL, Trise, and Tfall of inputs and clocks must be within 10% of each other.
3. For devices supplied with HSTL I/O input buffers. Compatible with both 1.8 V and 1.5 V I/O drivers.
