4.1.2
Note 1: If you use a microcontroller device outside the 0 to 85°C range for long periods of time, contact
Note 2: For the
For microcontroller devices, the following junction temperature range is used for reliability
predictions:
An estimation of the chip junction temperature, Tj, can be obtained from the equation:
Tj = 0°C ∼ 85°C
Tj = Ta + Q × ja
where:

Reliability predictions for microcontroller devices
Ta = ambient temperature (°C)
Q =
ja = package thermal resistance (°C/W)
The assumption is that the ambient temperature is not affected by any heat
transfers from the device.
