2. Grade 0 Qualification
7792B–AVR–05/09
The ATtiny87/ATtiny167 has been developed and manufactured according to the most strin-
gent quality assurance requirements of ISO-TS-16949 and verified during product qualification
as per AEC-Q100 grade 0.
AEC-Q100 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 ATtiny87/ATtiny167 lifetime would not satisfy the application end-of-life reliability
requirements, Atmel
Operating Life Test, High Temperature Storage Life, Data Retention, Thermal Cycles), far
beyond the AEC-Q100 requirements. Thereby, Atmel verified the ATtiny87/ATtiny167 has a
long safe lifetime period after the grade 0 qualification acceptance limits.
The valid domain calculation depends on the activation energy of the potential failure mecha-
nism that is considered. Therefore any temperature mission profile which could exceed the
AEC-Q100 equivalence domain shall be submitted to Atmel for a thorough reliability analysis
