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
