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 WE32K32-150Q EEPROM, 32K × 32-bit 150 ns 02 WE32K32-120Q EEPROM, 32K × 32-bit 120 ns 03 WE32K32-90Q EEPROM, 32K × 32-bit 90 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 M See figure 1 68 Ceramic, quad flatpack, dual cavity U See figure 1 66 1.075", hex-in-line, single cavity, with standoffs X See figure 1 66 Hex-in-line, single cavity, with standoffs Y 1/ See figure 1 66 Hex-in-line, single cavity, without standoffs Z See figure 1 68 Co-fired, single cavity, ultra low profile, quad flatpack

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