scope:

This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). This drawing describes device requirements for hybrid microcircuits to be processed in accordance with MIL-H-38534. Two product assurance classes, military high reliability (device class H) and space application (device class K) and a choice of case outlines and lead finishes are available and are reflected in the Part or identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-H-38534 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 Circuit function Access Time 01 WF128K32-150HQ5 FLASH EPROM, 128K × 32-bit 150 ns 02 WF128K32-120HQ5 FLASH EPROM, 128K × 32-bit 120 ns 03 WF128K32-90HQ5 FLASH EPROM, 128K × 32-bit 90 ns 04 WF128K32-70HQ5 FLASH EPROM, 128K × 32-bit 70 ns

This device class designator shall be a single letter identifying the product assurance level as follows:

Device class Device requirements documentation H or K Certification and qualification to MIL-M-38534

The case outline(s) shall be as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style S See figure 1 66 Hex-in-line, single cavity, with standoffs T See figure 1 66 Hex-in-line, single cavity, without standoffs U See figure 1 66 Hex-in-line, single cavity, with standoffs V See figure 1 66 Hex-in-line, single cavity, without standoffs W See figure 1 66 Hex-in-line, single cavity, with standoffs X See figure 1 66 Hex-in-line, single cavity, without standoffs Y See figure 1 66 Hex-in-line, single cavity, with standoffs Z See figure 1 66 Hex-in-line, single cavity, without standoffs

The lead finish shall be as specified in MIL-H-38534 for classes H and K. 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.
