PACKAGE THERMAL
SPECIFICATIONS
The 80C186EA/80L186EA is specified for operation
when T
C
(the case temperature) is within the range
of 0
§
C to 85
§
C (PLCC package) or 0

C to 106
§
C
(QFP-EIAJ) package. T
C
may be measured in any
environment to determine whether the processor is
within the specified operating range. The case tem-
perature must be measured at the center of the top
surface.
T
A
(the ambient temperature) can be calculated
from
i
CA
(thermal resistance from the case to ambi-
ent) with the following equation:

Typical values for
i
CA
at various airflows are given
in Table 10.
P (the maximum power consumption, specified in
watts) is calculated by using the maximum ICC as
tabulated in the DC specifications and V
CC
of 5.5V.
