Changes

The processor doesn't allow for measurement of the junction temperature, thus use of some indirect method is required, as described in the [[Power (Naon)]] section. Here you can find useful information related to the thermal characteristics of the package - extracted from the CPU datasheet - that, together with the contents of the TI application note "Semiconductor and IC Package Thermal Metrics" (http://www.ti.com/litv/pdf/spra953bspra953c), allows for estimation of the junction temperature Tj. The PsiJT and the θjc parameters identified in the AN are the most important ones to identify the difference between the external case temperature (which is easily measurable) and the internal junction temperature. Once this value is known, it is possible to determine the highest acceptable environment temperature to avoid reaching critical junction temperature.
