AEC-Q1 qualification relies on temperature accelerated stress testing. High temperature field usage however may result in less significant stress test acceleration. In order to prevent the risk that ATmega88/168 lifetime would not satisfy the application end-of-life reliability requirements, Atmel has extended the testing, whenever applicable (High Temperature Operating Life Test, High Temperature Storage Life, Data Retention, Thermal Cycles), far beyond the AEC-Q1 requirements. Thereby, Atmel verified the ATmega88/168 has a long safe lifetime period after the grade qualification acceptance limits. The valid domain calculation depends on the activation energy of the potential failure mechanism that is considered. Examples are given in Figure Therefore any temperature mission profile which could exceed the AEC-Q1 equivalence domain shall be submitted to Atmel for a thorough reliability analysis.
