scope:
This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). Two product assurance classes, consisting of military high reliability (device classes B, Q, and M) and space application (device classes S and V), and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). Device class M microcircuits represent non-JAN class B microcircuits accordance with 1.2.1 of MIL-STD-883, "Provisions for the use of MIL-STD-883 in conjunction with compliant non-JAN devices". When available, a choice of radiation hardness assurance (RHA) levels are reflected in the PIN.
The PIN shall be as shown in the following example:
Device classes M, B, and S RHA marked devices shall meet the MIL-M-38510 specified RHA levels and shall be marked with the appropriate RHA designator. Device classes Q and V RHA marked device shall meet the MIL-I-38535 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non RHA device.
The device type(s) shall identify the circuit function as follows:
Device type Generic number 1/ Circuit function Access time 01 27C020 (256K × 8) UVEPROM 250 ns 02 27C020 (256K × 8) UVEPROM 200 ns 03 27C020 (256K × 8) UVEPROM 150 ns
The device class designator shall be a single letter identifying the product assurance level as follows:
Device class Device requirements documentation M Vendor self-certification to the requirements for non-JAN class B microcircuits in accordance with 1.2.1 of MIL-STD-883 B or S Certification and qualification to MIL-M-38510 Q or V Certification and qualification to MIL-I-38535
The case outline(s) shall be as designated in MIL-STD-1835 and as follows:
Outline letter Descriptive designator Terminals Package style 2/ X GDIP1-T32 or CDIP2-T32 32 Dual-in-line package Y CQCC1-N32 32 Rectangular leadless chip carrier
The lead finish shall be as specified in MIL-M-38510 for classes M, B, and S or MIL-I-38535 for classes Q and V. Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
