7、 choice of case outlines and lead finishes which 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. 1.2 PIN. The PIN shall be as shown in the following example: 5962 - 96902 01 H M X Feder

RHA marked devices shall meet the MIL-PRF-38534 specified RHA leve
9、ls and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type(s). The device type(s) identify the circuit function as follows: Device type 1/ Generic number Circuit function Access time 01 WMS256K16-35DL SRAM, 256K x 16-bit 35 ns 02 WMS256K16-25

This device class designator shall be a single letter identifying the product assurance level. All levels are defined by the requirements of MIL-PRF-385
11、34 and require QML Certification as well as qualification (Class H, K, and E) or QML Listing (Class G and D). The product assurance levels are as follows: Device class Device performance documentation K Highest reliability class available. This level is intended for use in space applications. H Stan
12、dard military quality class level. This level is intended for use in applications where non-space high reliability devices are required. G Reduced testing version of the standard military quality class. This level uses the Class H screening and In-Process Inspections with a possible limited temperat
13、ure range, manufacturer specified incoming flow, and the manufacturer guarantees (but may not test) periodic and conformance inspections (Group A, B, C and D). E Designates devices which are based upon one of the other classes (K, H, or G) with exception(s) taken to the requirements of that class. T
14、hese exception(s) must be specified in the device acquisition document; therefore the acquisition document should be reviewed to ensure that the exception(s) taken will not adversely affect system performance. 1/ Due to the nature of the 4 transistor design of the die used in these device types, top
15、ologically pure testing is important, particularly for high reliability applications. The device manufacturer should be consulted concerning their testing methods and algorithms.
