The following table shows the temperature thresholds of all sensors.
Temperature values are measured with an accuracy of 1°C.
5.2 Thermal Regulation
When developing applications using the AT8404, the system integrator must be aware of the overall system
thermal requirements. A system chassis must be provided which satisfies these requirements.
Measurements proofed that operation in worst case conditions (maximum ambient temperature and power
consumption including AMCs) is possible while all temperatures of on-board components stay below their
critical thresholds. Note that the AMCs operated in the AT8404 have their own thermal and airflow require-
ments which have to be observed.

WARNING
As Kontron assumes no responsibility for any damage to the AT8404 or
other equipment resulting from overheating any of the components, it is
highly recommended that system integrators as well as end users confirm
that the operational environment of the AT8404 complies with the ther-
mal considerations set forth in this document.
