3. REQUIREMENTS
MIL-M-38510/502A
3.1 Qualification. Microcircuits furnished under this specification shall be products that are manufactured by a manufacturer authorized by the qualifying activity for listing on the applicable qualified manufacturers list before contract award (see 4.2 and 6.3). When manufacturer programmed devices are delivered to the user, an altered item drawing shall be prepared by the procuring activity to specify the required program configuration.
3.2 Item requirements. The individual item requirements shall be in accordance with MIL-PRF-38535 and as specified herein or as modified in the device manufacturer's Quality Management (QM) plan. The modification in the QM plan shall not affect the form, fit, or function as described herein.
3.3 Design, construction, and physical dimensions. The design, construction, and physical dimensions shall be as specified in MIL-PRF-38535 and herein.
3.3.1 Terminal connections. The terminal connections shall be as specified on figure 1.
3.3.2 Truth tables.
3.3.2.1 Unprogrammed devices. The truth tables for unprogrammed devices for contracts involving no altered item drawing shall be as specified on figure 2. When required in groups A, B, or C (see 4.4), the devices shall be programmed by the manufacturer prior to test as per table A-I (a minimum of 50% of the total number of gates programmed) or to any altered item drawing pattern which includes at least 25 percent of the total number of gates programmed.
3.3.2.2 Programmed devices. The truth table for programmed devices shall be as specified by the altered item drawing.
3.3.3 Logic diagrams. The logic diagram shall be as specified on figure 3.
3.3.4 Case outlines. Case outlines shall be in accordance with MIL-STD-1835 and 1.2.3 herein.
3.4 Lead material and finish. The lead material and finish shall be in accordance with MIL-PRF-38535 (see 6.6).
3.5 Electrical performance characteristics. Unless otherwise specified, the electrical performance characteristics are as specified in table I, and apply over the full recommended case operating temperature range.
3.6 Electrical test requirements. Electrical test requirements shall be as specified in table III and (where applicable), the altered item drawing for the applicable device type and device class. The subgroups of table III which constitute the minimum electrical test requirements for screening, qualifications, and quality conformance, by device class, are specified in table II.
3.7 Marking. Marking shall be in accordance with MIL-PRF-38535. For programmed devices, the altered item drawing number shall be added to the marking by the programming activity.
3.8 Processing options. Since the FPLA is an unprogrammed device capable of being programmed by either the manufacturer or the user to result in a wide variety of configurations, two processing options are provided for
selection in the contract, using an altered item drawing.
3.8.1 Unprogrammed FPLA delivered to the user. All testing shall be verified through group A testing as defined in 3.3.2.1, tables II and III. It is recommended that users perform subgroups 7 and 9 after programming to verify the specific program configuration.
3.8.2 Manufacturer programmed FPLA delivered to the user. All testing requirements and quality assurance provisions herein, including the requirements of the altered item drawing, shall be satisfied by the manufacturer prior to delivery.
3.9 Microcircuit group assignment. The devices covered by this specification shall be in microcircuit group number 14 (see MIL-PRF-38535, appendix A).
