Package Thermal Resistance
The Intel
80200 processor is specified for operation when T
C
(case temperature) is within the
range of 0°C to 90°C. Case temperature may be measured in any environment to determine
whether the device is within its specified operating range. The case temperature should be
measured at the center of the top surface, opposite the pins.
θ
CA
is the thermal resistance from case to ambient. Use the following equation to calculate T
A
, the
maximum ambient temperature to conform to a particular case temperature:
T
A
= T
C
- P (
θ
CA
)
Junction temperature (T
J
) is commonly used in reliability calculations. T
J
can be calculated from
θ
JC
(thermal resistance from junction to case) using the following equation:
T
J
= T
C
+ P (
θ
JC
)
Similarly, when T
A
is known, the corresponding case temperature (T
C
) can be calculated as
follows:
T
C
= T
A
+ P (
θ
CA
)
Figure 3
and
Figure 4
show an application of the supplied thermal data. Here, we plot the case
temperature under several conditions.
