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 WMF512K8-150 FLASH EPROM, 512K × 8-bit 150 ns 02 WMF512K8-120 FLASH EPROM, 512K × 8-bit 120 ns 03 WMF512K8-90 FLASH EPROM, 512K × 8-bit 90 ns 04 WMF512K8-70 FLASH EPROM, 512K × 8-bit 70 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:

Outline letter Descriptive designator Terminals Package style T See figure 1 32 Ceramic flatpack, leadformed U See figure 1 32 Ceramic flatpack X See figure 1 32 Co-fired ceramic, single cavity, dual-in-line Y See figure 1 32 Co-fired ceramic, single cavity, SOJ

The lead finish shall be as specified in MIL-PRF-38534.
