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:

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 WSF512K16-72Q 512K × 16-bit SRAM, 70nS 512K × 16-bit Flash 120nS 02 WSF512K16-39Q 512K × 16-bit SRAM, 35nS 512K × 16-bit Flash 90nS

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:

Outline letter Descriptive designator Terminals Package style M See figure 1 68 Ceramic, Quad flatpack, dual cavity X See figure 1 66 Hex-in-line, single cavity, withstandoffs

The lead finish shall be as specified in MIL-PRF-38634.
