Package Thermal Specifications
The 80C186EC 80L186EC is specified for operation
when TC (the case temperature) is within the range
of b40 C to a100 C TC 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
TA (the ambient temperature) can be calculated
from iCA (thermal resistance from the case to ambi-
ent) with the following equation
TA e TC b P iCA
Typical values for iCA at various airflows are given
in Table 9 P (the maximum power consumption
specified in Watts) is calculated by using the maxi-
mum ICC and VCC of 5 5V
