Package Thermal Specifications
The 80960Jx is specified for operation when T
C
(case temperature) is within the range of
0°C to
100°C for PGA, MPBGA and PQFP packages. An extended temperature device is also available in
a PQFP package with T
C
-40°C to 100°C. Case temperature may be measured in any environment
to determine whether the 80960Jx 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, if T
A
is known, the corresponding case temperature (T
C
) can be calculated as follows:
T
C
= T
A
+ P (
θ
CA
)
Compute P by multiplying I
CC
from Table 22 and V
CC
. Values for
θ
JC
and
θ
CA
are given in
Table 12 for the PGA package, Table 13 for the MPBGA package, and Table 14 for the PQFP
package. For high speed operation, the processor’s
θ
JA
may be significantly reduced by adding a
heatsink and/or by increasing airflow.
Tables 15, 16, and 17 show the maximum ambient temperature (T
A
) permitted without exceeding
T
C
for the PGA, MPBGA, and PQFP packages. The values are based on typical I
CC
and V
CC
of
+3.3 V, with a T
CASE
of +100°C.
