Case Studies
The GEM program supports over 560 weapon systems. Here are some of our example case studies.
C - 17
| Application | C-17 Landing Gear |
| Obsolete Device | EP1800 Erasable Programmable Logic Device |
| Emulation Solution | In this application the device is only programmed once, therefore, the GEM Program was able to provide a Form, Fit, Function and Interface (F3I) hard-coded ASIC replacement for the obsolete programmable microcircuit. For the last 17 years, the GEM Program had provided 89 delivery orders of over 400 individual parts. The GEM33320BXC part is still actively available. |
| Customer | Crane Hydro Air, a subcontractor for Boeing, has successfully used the GEM Program Emulation of a programmable device. |
| Benefit to Program | Eliminate system redesign due to part's obsolescence provide long-term production support |
Bradley
| Application | Bradley M2A2 Armored fighting vehicle, microcircuit used in turret distribution box, system control box and gun control unit. |
| Obsolete Device | CMOS-Compatable dual NAND peripheral driver with open collector, outputs generic DS1632. NSN 5962-01-376-2175, SMD PN 5962-9052201PA. Replacement Emulation PN GEM34301QPA. Additional Emulated QML-38535 SMD PN's: 5962-9052201PC, 5962-9052201XA, 5962-9052201XC. |
| Emulation Solution | In this application, prototypes were insertion tested prior to production manufacturing of a form, fit, function Emulation of the original part with matching critical performance parameters. |
| Customer | DLA, Army, Curtis Wright Inc., United Defense, and all subcontractors |
| Benefit to Program | Averted Bradley production and repair line shutdown and provided permanent production support |
| Manufacturing Support | Production status - On-demand manufacturing capability in place with over 13,600 parts delivered |
B-2
| Application | Develop wafer fabrication processes and arrays to provide GEM solutions for rad hard requirements |
| Customer | United States Air Force |
| Contract Vehicle/Funding | Cost share DLA/B-2 Program MILSVC |
| Test Results | For the dose rate test, no upset, latch-up or burnout was observed through the highest levels tested
For total dose all samples were through 1Mrad (Si) |
| Benefit to Program | U.S. Trusted source of microcircuits meeting rad-hard requirements for B-2 |
F-15
| Application | F-15 Eagle airborne computer - Flight Control Module |
| Obsolete Device | Custom MIL-STD-1750 microprocessor module (MDC 281) |
| Emulation Solution | In this application, SRI, in joint development with Boeing, utilized the Emulation Technology to reverse engineer three obsolete microcircuits to one ASIC on the same daughter card, maintaining a Form, Fit, Function, and interface equivalent solution. |
| Customer | DLA, F-15 Systems Program Office (SPO), Boeing, BAE Syatems, and all sub-contractors |
| Benefit to Program | Eliminated hardware and software redesign due to part obsolesence, and provides long term production support |
| Manufacturing Support | Prototypes delivered in 2007 for SRU, LRU, ATP, ESS, Avionics Intergration and F-15 in-flight testing. Production Status - On-demand manufacturing capability in-place with 355 individual parts delivered over 38 separate shipments since 2010 |
Phalanx
| Application | Phalanx Close-In Weapon System |
| Obsolete Device | XR-2240, NSN 5962-01-507-5909, SMD P/N 5962-0050701QEA Programmable Timer/Counter |
| Emulation Solution | A sample device was electronically reverse engineered and reference information was used to create a Form-Fit-Function-Interface Emulation of the original part with matching critical programmable timing precision. |
| Customer | DLA, Raytheon, Curtis Wright Inc., and all sub-contractors |
| Benefit to Program | Eliminated hardware and software redesign due to part obsolesence, and provides long-term production support. |
| Manufacturing Support | Parts were system validated with a populated Circuit Card Assembly (CCA) in the field prior to live action firing tests. Production Status - On-demand manufacturing capability in-place with 1,476 parts delivered over 37 shipments since 2004 |
