scope:

This drawing documents five product assurance classes, class D (lowest reliability), class E, (exceptions), class G (lowest high reliability), class H (high reliability), and class K, (highest reliability) 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:

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 WF128K32-200HQ FLASH EPROM, 128K × 32-bit 200 ns 02 WF128K32-150HQ FLASH EPROM, 128K × 32-bit 150 ns 03 WF128K32-120HQ FLASH EPROM, 128K × 32-bit 120 ns

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

Device class Device performance documentation D, E, G, H or K Certification and qualification to MIL-PRF-38534

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