Grade 0 Qualification
The ATtiny261/461/861 has been developed and manufactured according to the most stringent
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 ATtiny261/461/861 lifetime would not satisfy the application end-of-life reliability require-
ments, Atmel has extended the testing, whenever applicable (High Temperature Operating Life
Test, High Temperature Storage Life, Data Retention, Thermal Cycles), far beyond the
AEC-Q100 requirements. Thereby, Atmel verified the ATtiny261/461/861 has a long safe life-
time 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
