Peripheral operating requirements and behaviors
3.
Determined according to Method 1012.1 of MIL-STD 883, Test Method Standard, Microcircuits, with the cold plate
temperature used for the case temperature. The value includes the thermal resistance of the interface material
between the top of the package and the cold plate.
4.
Determined according to JEDEC Standard JESD51-2, Integrated Circuits Thermal Test Method Environmental
Conditions—Natural Convection (Still Air).
