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 monolithic microcircuits to be processed in accordance with class H requirements of MIL-PRF-38534. A choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN).

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-PRF-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 WMF128K8-150CQ5 FLASH EPROM, 128K × 8-bit 150 ns 02 WMF128K8-120CQ5 FLASH EPROM, 128K × 8-bit 120 ns 03 WMF128K8-90CQ5 FLASH EPROM, 128K × 8-bit 90 ns 04 WMF128K8-70CQ5 FLASH EPROM, 128K × 8-bit 70 ns 05 WMF128K8-60CQ5 FLASH EPROM, 128K × 8-bit 60 ns

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

Device class Device requirements documentation H Certification and qualification to MIL-PRF-38534

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

Outline letter Descriptive designator Terminals Package style T See figure 1 32 Flatpack, ceramic, single cavity X See figure 1 32 SOJ, ceramic, single cavity Y See figure 1 32 DIP, ceramic, single cavity

The lead finish shall be as specified in MIL-PRF-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.
