dent and can be minimized by such thermal management techniques as heat sinks,
ambient air cooling and thermal convection. Thus, good thermal management on the
part of the user can significantly reduce θ
tution of θ
temperature.
The microcircuits shall meet all mechanical environmental requirements of either MIL-
STD-883 for class B devices or Atmel standards.
The document that defines the marking is identified in the related reference documents.
Each microcircuit is legible and permanently marked with the following information as
minimum:
•
•
•
•
•
•
Those quality levels are in accordance with MIL-M-38535 and method 5005 of MIL-
STD-883. Groups A and B inspections are performed on each production lot. Groups C
and D inspection are performed on a periodical basis.
All static and dynamic electrical characteristics specified. For inspection purposes, refer
to relevant specification:
•
Table 5 and Table 6: Static Electrical Characteristics for all electrical variants. Test
methods refer to IEC 748-2 method number, where existing.
Table 7 and Table 8: Dynamic Electrical Characteristics. Test methods refer to this
specification.
