Mechanical and
Environmental
The microcircuits shall meet all mechanical environmental requirements of either MIL-
STD-883 for class B devices.
Marking
The document defines the markings that are identified in the related reference docu-
ments. Each microcircuit is legible and permanently marked with the following
information as minimum:
Atmel-Grenoble Logo
Manufacturer
’
s Part Number
Class B Identification
Date-code of inspection lot
ESD Identifier if Available
Country of Manufacturing
Quality Conformance
Inspection
DESC/MIL-STD-883
Is in accordance with MIL-M-38510 and method 5005 of MIL-STD-883. Group A and B
inspections are performed on each production lot. Group C and D inspection are per-
formed on a periodical basis.
Electrical
Characteristics
General Requirements
All static and dynamic electrical characteristics specified and the relevant measurement
conditions are given below. For inspection purpose, refer to relevant specification:
Static electrical characteristics for all electrical variants.
Dynamic electrical characteristics for 68882-16 (16.67 MHz), 68882-20 (20 MHz),
68882-25 (25 MHz) and 68882-33 (33 MHz).
For static characteristics, test methods refer to clause
“
Test Load
”
on page 13 hereafter
of this specification (Table 5).
For dynamic characteristics (Tables 6 and 7), test methods refer to IEC 748-2 method
number, where existing.
Table 5.
