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. Extended temperature devices are also available in
a PQFP package and an MPBGA 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 31,
“
80960Jx ICC Characteristics
”
on page 45 and V
CC
.
See the following tables for
θ
JC
and
θ
CA
values:
For high speed operation, the processor
’
s
θ
JA
may be significantly reduced by adding a heatsink
and/or by increasing airflow.
Refer to the following tables for 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
C
of +100
°
C.
