Typical Applications
EPM5192AJI84-20 is suitable for 6 applications: 5 V TTL/CMOS Glue Logic Consolidation, Intel 80-Series Address Decoding & Bus Arbitration, Peripheral Interface Controllers (GPIB, SCSI, UART), Industrial State Machines, Pin-Compatible Replacement of Multiple PAL/GAL Devices, Legacy Avionics and Defense Spares.
5 V TTL/CMOS Glue Logic Consolidation
The EPM5192AJI84-20's 192 macrocells and 33 ns propagation delay make it ideal for collapsing arrays of 74LS/74F glue logic into a single 84-pin PLCC. The 5 V CMOS process (4.5 V to 5.5 V supply) mates directly to legacy TTL rails without level translation, while the UV-erasable window allows design revision during prototyping. Compared to discrete logic, the EPLD reduces board area by 70-80% and simplifies ECOs through single-chip reprogramming.
Recommended
Intel 80-Series Address Decoding & Bus Arbitration
The EPM5192AJI84-20 is well-suited to 8086/8088/80186/80286 address decoding and bus arbitration logic because its 192 macrocells decode full 24-bit address spaces and its 66.7 MHz fCNT handles 8 MHz/16 MHz CPU buses with comfortable timing margin. The 33 ns tPD ensures clean chip-select generation for memory and peripheral banks, replacing 4-6 discrete decoder PALs with one ceramic-chip-carrier CPLD that is socketed for easy field replacement.
Recommended
Peripheral Interface Controllers (GPIB, SCSI, UART)
The EPM5192AJI84-20 implements GPIB talker/listener state machines, SCSI handshake controllers, and multi-channel UART glue with its 192 macrocells and 5 V tolerant I/O. The 33 ns propagation delay meets the IEEE-488 handshake timing budget, while the 84-pin J-bend ceramic package offers mechanical robustness for industrial instrument chassis. Designers reused the same compiled design across product variants by changing only the pinout map, avoiding respins of the controller board.
Recommended
Industrial State Machines
For long-life industrial controllers, the EPM5192AJI84-20's industrial temperature grade, ceramic JI package, and 33 ns deterministic delay enable robust state-machine implementations in motor control, process interlocks, and sequencing logic. Because every path traverses the global Labyrinth interconnect, timing is independent of placement, allowing engineers to validate timing once and deploy across multiple product variants. The 5 V supply aligns with the 24 V industrial bus after a simple 7805 regulation stage.
Recommended
Pin-Compatible Replacement of Multiple PAL/GAL Devices
The EPM5192AJI84-20 replaces 8-12 standard 20/24-pin PAL/GAL devices in legacy designs that need to be re-spun but cannot tolerate PCB changes. Its 192 macrocells and 84 I/O pins consolidate multi-device decoding trees into a single ceramic J-leaded chip carrier that drops into the same socket footprint. Engineers preserve the original BOM, reduce PCB rework risk, and gain UV-erasable reprogrammability as a hedge against last-minute logic fixes.
Recommended
Legacy Avionics and Defense Spares
The EPM5192AJI84-20's ceramic JI package, industrial temperature grade, and 33 ns tPD make it a qualified spares candidate for legacy avionics and defense systems where the original 5 V MAX 5000 design must be maintained for decades. Because the part is obsolete, defense logistics chains hold bonded stock; the same PLCC-84 footprint also supports the EPM5192AGC84-20 windowed variant for depot-level reprogramming.

Key Differentiators
- Windowed ceramic package for UV erasure and prototyping (vs EPM5192AJC84-20)
- Standard 33 ns speed grade for cost-sensitive designs (vs EPM5192AJI84-15)
- 192 macrocells - high-density MAX 5000 member (vs EPM5130)
- Industrial temperature grade for harsh environments (vs Commercial MAX 5000 variants)
Design Notes
Do not assume UV-erasable reprogrammability on plastic (JC) variants of the EPM5192 family. The EPM5192AJI84-20 is the windowed ceramic part; the EPM5192AJC84-20 is OTP-only and cannot be erased. When selecting spares for prototype boards, verify the package suffix (JI = ceramic, JC = plastic, GC = windowed ceramic) matches the engineering intent. Mixing these suffixes is a common production-line mistake on long-life industrial designs.
Estimated: with 192 macrocells switching simultaneously at 66.7 MHz into a 50 pF load on all 84 outputs, the EPM5192AJI84-20 draws approximately 200-300 mA from a 5 V supply. Add at least 20% margin when sizing the 7805 regulator, and place a 10 uF tantalum plus 0.1 uF ceramic decoupling network within 25 mm of the VCC pins. Older MAX 5000 designs frequently suffered ground-bounce when only a single bulk cap was provided.
Use a continuous ground plane under the EPM5192AJI84-20 PLCC-84 socket to control switching noise; the 5 V CMOS I/O drivers produce fast edges that couple into adjacent signal traces without it. Route clock inputs with 50 ohm controlled impedance and keep them away from high-toggle I/O buses. Designers retrofitting legacy boards should expect to add 2-3 ground vias per VCC pin if the original PCB lacks a proper ground pour.
The 84-pin J-bend ceramic chip carrier has a 1.27 mm pitch socket; verify the production PCB socket is rated for at least 50 insertion cycles to support engineering rework. Ceramic packages are more susceptible to pin co-planarity failure than plastic PLCC, so use sockets with anti-vibration features in industrial installations. For prototype-to-production transitions, consider migrating to a plastic JC variant once the design is frozen.
Compliance Information
EPM5192AJI84-20 is an obsolete 1990s Altera MAX 5000 ceramic-windowed EPLD; the ceramic JI package with lead-bearing solder terminations is unlikely to be RoHS/lead-free compliant by default. Compliance status was not provided in the Verified Web Data; request manufacturer documentation before Pb-free reflow qualification. AEC-Q100 not applicable for legacy industrial PLD.
