Thermal Impedance data is based on a number of of samples from mulitple lots and should be viewed as a typical number.
Please refer to JEDEC standard JESD51-6.
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.
Compatible with both 1.8 V and 1.5 V I/O drivers.
These are DC test criteria. DC design criteria is V
