scope:

This drawing documents two product assurance classes, high reliability (device class H) and space application (device class K) 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 WE-128K32-300HQ EEPROM, 128K × 32-bit 300 ns 02 WE-128K32-250HQ EEPROM, 128K × 32-bit 250 ns 03 WE-128K32-200HQ EEPROM, 128K × 32-bit 200 ns 04 WE-128K32-150HQ EEPROM, 128K × 32-bit 150 ns

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

Device class Device performance documentation 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, dual cavity, quad flatpak N See figure 1 68 Ceramic, quad flatpak T See figure 1 66 Hex-in-line, single cavity, with standoffs U See figure 1 66 Hex-in-line, single cavity, without standoffs X See figure 1 66 Hex-in-line, single cavity, with standoffs Y See figure 1 66 Hex-in-line, single cavity, without standoffs 4 See figure 1 66 1.075", hex-in-line, single cavity, with standoffs 5 See figure 1 66 1.075", hex-in-line, single cavity, with standoffs

The lead finish shall be as specified in MIL-PRF-38534 for classes H and K.
