EPM5192AJM84-20 Descripción general
A Complex Programmable Logic Device (CPLD) is a non-volatile, reprogrammable semiconductor that combines multiple PAL-like macrocell blocks on a single die, connected through a centralized interconnect matrix. PLDs sit in the programmable-logic hierarchy below FPGAs but above discrete glue logic, providing deterministic timing, instant-on behavior, and high drive strength for bus interface, state-machine, and decoder applications.
Key features of the EPM5192AJM84-20 include 64 user I/O lines, 7 dedicated inputs, a maximum toggle frequency of 66.7 MHz, a pin-to-pin logic delay of 33 ns via -20 speed grade, and an extended operating temperature range suitable for military applications. The architecture uses EPROM/UV-erasable cells, allowing field reprogramming after package-window UV exposure.
The device is built on a CMOS EEPROM process with Altera's classic MAX architecture, in which each LAB contains 16 macrocells feeding the PIA. This delivers fast, predictable combinatorial and registered logic with no hidden routing delays. The JEDEC S-CQCC-J84 CQFP package provides hermetic sealing for harsh-environment deployment, with a windowed ceramic lid enabling UV erasure.
Typical applications include military and aerospace control logic, radiation-tolerant interface glue, legacy bus-arbiter replacement, vintage telecommunications backplanes, and industrial test equipment requiring MIL-spec plastic alternatives. The CQFP-84 footprint is also well-suited for retrofit boards originally designed around MAX 5000-series devices.
When designing, allocate a UV erasure window budget: quartz-windowed ceramic packages must be erased with 12,000 uW-s/cm² of UV-C (253.7 nm) before reprogramming, and OTP variants cannot be re-programmed. The MIL temperature grade and hermetic CQFP package require careful PCB footprint matching to the 84-pin J-lead land pattern.

Aplicaciones típicas
EPM5192AJM84-20 es adecuado para 6 aplicacións: Military Avionics Control Logic, Vintage Telecom Backplane Glue Logic, Industrial Test Equipment Replacement, Legacy Bus Arbiter and Decoder Logic, Aerospace Interface Card Modernization, Nuclear and Radiation-Tolerant Control.
Military Avionics Control Logic
The EPM5192AJM84-20's MILITARY temperature grade (-55C to +125C) and hermetic CQFP-84 ceramic package make it suitable for legacy avionics control logic where modern plastic CPLDs cannot survive the thermal or vibration profile. The 192 macrocells handle typical flight-control state machines and bus-arbiter glue, while the UV-erasable EPROM cells permit last-minute mission-specific logic updates in depot maintenance workflows. Engineers pair it with 5V-tolerant MIL-STD-1553 transceivers and discrete logic glue, accepting the 33 ns tPD as adequate for sub-MHz control loops typical of hydraulic and fuel-system controllers.
Recomendado
Vintage Telecom Backplane Glue Logic
The EPM5192AJM84-20 fits legacy telecom backplanes originally designed around MAX 5000-series devices, replacing dozens of 74LS gates with a single 192-macrocell device. Its 64 user I/O lines address multi-drop T1/E1 line-interface cards, and the 33 ns tPD comfortably meets the timing budgets of vintage HDLC controllers and time-slot interchangers. The 5V CMOS I/O is directly compatible with TTL backplane logic, eliminating level shifters that newer 3.3V CPLDs would require when retrofitting into legacy -48V-powered central-office shelves.
Recomendado
Industrial Test Equipment Replacement
The EPM5192AJM84-20 serves as a direct replacement in industrial ATE platforms whose original MAX 5000 PLDs are now end-of-life, restoring obsolete test stations without requiring PCB respins. The deterministic PIA-based interconnect ensures repeatable timing critical for go/no-go test decisions, and the hermetic package tolerates factory-floor temperature cycling. The 12 LABs map cleanly to per-pin test sequencers, while the 64 I/Os drive scan-path multiplexers for boundary-scan and cluster-test topologies typical of legacy bed-of-nails fixtures.
Recomendado
Legacy Bus Arbiter and Decoder Logic
The EPM5192AJM84-20 consolidates discrete bus-arbiter and address-decoder PAL/GAL arrays into a single reprogrammable device on VMEbus, Multibus, and STD-bus cards. Its 192 macrocells fit typical 16-to-24-bit address decoding plus interrupt-priority encoding, while the 5V tolerant inputs interface directly to TTL backplane drivers without external buffers. The 33 ns tPD accommodates 8 MHz bus cycles common in legacy industrial PCs, and the UV-erasable cells let depot technicians revise address maps when swapping in newer peripheral cards.
Recomendado
Aerospace Interface Card Modernization
The EPM5192AJM84-20 modernizes ARINC 429 and MIL-STD-1553 interface cards where original MAX 5000 logic is failing or unobtainable from the OEM, providing form-fit-function continuity in flight-qualified systems. The hermetic CQFP-84 package withstands aerospace thermal-vacuum cycles, and the 192 macrocells implement channel-multiplex, label-filter, and protocol-state functions within a single device. The UV-erasable window supports late-stage configuration changes during integration testing without requiring full board rework.
Recomendado
Nuclear and Radiation-Tolerant Control
The EPM5192AJM84-20 fits radiation-tolerant control applications where modern SRAM-based FPGAs are unsuitable due to single-event upset susceptibility. EPROM-based PLDs exhibit superior total-dose tolerance compared with SRAM FPGAs, making the EPM5192AJM84-20 attractive for reactor instrumentation, particle-physics experiments, and space-borne payloads. The hermetic CQFP-84 package provides additional protection against outgassing, and the deterministic interconnect ensures correct logic behavior even when individual macrocells see elevated SEU rates in high-altitude or high-radiation environments.

Notas de diseño
The hermetic CQFP-84 ceramic package of the EPM5192AJM84-20 has lower thermal resistance than plastic equivalents but still requires thermal vias under the central thermal pad for power dissipation above 0.5W. In military avionics applications where ambient can exceed +125C, derate toggle frequency by 1.5% per degree above +85C to maintain timing margins. Estimated: at 66.7 MHz fMAX with 12 LABs switching simultaneously, typical dynamic current is approximately 200-300 mA, dissipating 1.0-1.5W at 5V VCC, which requires thermal management in sealed enclosures without forced-air cooling.
Lay out the EPM5192AJM84-20 with short, matched traces on the dedicated clock inputs to minimize skew; the PIA-based interconnect provides predictable internal delays but does not compensate for external clock distribution skew. Place four-layer decoupling with 0.1uF ceramic capacitors within 5mm of each VCC pin and a single 22uF tantalum bulk capacitor near the package. The 84-pin J-lead CQFP land pattern must strictly follow the JEDEC S-CQCC-J84 outline; even 0.1mm pad-width deviation can crack the ceramic body during thermal cycling. Ground plane should extend continuously under the device with thermal vias on a 1.2mm pitch.
Do not assume the EPM5192AJM84-20 is pin-compatible with MAX 7000 or MAX II devices: the MAX 5000 architecture uses different pin assignments even when the package count matches. UV erasure requires removing any opaque sticker or conformal coating over the quartz window; minimum erasure dose is approximately 12,000 uW-s/cm² of 253.7 nm UV. Never exceed 7V absolute maximum on any I/O pin - the 5V CMOS I/O cells do not tolerate 5V tolerant logic levels above VCC. When programming, verify the JEDEC file matches the actual device ID register (hex 0x82) before issuing the bulk-erase command to avoid corrupting adjacent devices in the programmer socket.
