Typical Applications
EPM5192LI-1 is suitable for 7 applications: Military Avionics Replacement Logic, 5V Bus Interface Bridge, Industrial Automation Controllers, Legacy Telecom Backplane Glue Logic, Medical Imaging Front-End Control, Retro Computer and Hobbyist Restoration, Defense System Long-Life Spares.
Military Avionics Replacement Logic
The EPM5192LI-1 is well-suited to military avionics replacement programs because the ceramic JLCC windowed package meets MIL-STD-883 environmental screening and the -1 speed grade delivers 40 MHz deterministic timing for bus-interface state machines. With 192 macrocells, the part absorbs address-decoding, interrupt-arbitration, and discrete I/O control logic previously scattered across discrete TTL. Compared with modern FPGAs, the EPM5192LI-1 instant-on non-volatile behavior eliminates configuration-PROM loading time - critical in safety-critical flight controls where deterministic power-on state is mandatory. The wide -55C to +125C industrial/military operating range and 5V-only supply also allow direct insertion into legacy 5V signal chains without level translation.
Recommended
5V Bus Interface Bridge
The EPM5192LI-1 serves as a 5V bus-interface bridge between legacy peripheral buses (e.g., ISA, VME, or proprietary MIL-STD-1553 bridges) and modern processor buses. Its 192 macrocells and PIA-based interconnect easily implement 16-bit or 32-bit address decoders, wait-state generators, and chip-select logic, while the 40 MHz toggle frequency handles typical peripheral bus clocks without timing closure issues. The non-volatile EPROM-based configuration means the bridge powers up in a known-good state - critical for systems where an unconfigured FPGA would leave peripherals un-addressable. The 5V single-supply rail eliminates the need for level-shifters on TTL and CMOS legacy interfaces.
Recommended
Industrial Automation Controllers
In factory-floor PLC and motion-controller designs, the EPM5192LI-1 implements deterministic glue logic - encoder quadrature decoders, PWM generators, watchdog timers, and Modbus/Profibus address-decode glue - with nanosecond-class propagation delay predictability. The MAX 5000 PIA-based interconnect delivers constant tPD regardless of placement, eliminating the timing variation that complicates FPGA-based glue logic in real-time control loops. The ceramic package tolerates the temperature and vibration profile of industrial enclosures, and the 5V rail aligns with industrial 24V->5V power architectures. Compared to a discrete 74LS/74HC logic implementation, the EPM5192LI-1 reduces board area by 4-8x while preserving the deterministic timing that PLC programmers expect.
Recommended
Legacy Telecom Backplane Glue Logic
The EPM5192LI-1 is commonly deployed as glue logic on legacy telecom backplanes - T1/E1 framers, SCSI termination networks, and central-office switching fabrics - where the 5V supply rail and 192-macrocell density align with classic system architectures. The deterministic PIA timing lets designers specify worst-case propagation delay in datasheets rather than statistical FPGA timing closure reports, which is a contractual requirement in many telecom-equipment vendor specifications. Ceramic-package reliability supports the 20-30 year operational lifetime expected of central-office equipment, and Altera's continued NRND support preserves spare-part supply for in-service units through the 2030s.
Recommended
Medical Imaging Front-End Control
In ultrasound and X-ray imaging front-ends, the EPM5192LI-1 controls beamformer sequencing, transducer multiplexing, and ADC trigger timing where deterministic sub-100ns latency is mandatory. The 40 MHz toggle frequency comfortably handles 10-20 MHz beamformer event rates, while the 192 macrocells absorb the entire front-end state machine in a single device - reducing BOM complexity and improving MTBF. The instant-on non-volatile behavior ensures the imaging system powers up into a safe transducer state without FPGA configuration latency. The 5V supply rail also matches the analog front-end power rails, eliminating the need for separate level translation at the transducer interface.
Recommended
Retro Computer and Hobbyist Restoration
The EPM5192LI-1 finds a niche in retro-computer restoration and hobbyist projects that replicate 1980s/1990s architectures. Designers building open-source replicas of classic bus systems (e.g., S-100, STEbus, or NuBus) can substitute the original 74LS glue-logic forest with a single EPM5192LI-1 programmed via MAX+PLUS II. The 5V supply matches classic bus rails, the UV-erasable window allows iterative development with hardware erasure, and the ceramic package adds an aesthetic authenticity that aligns with the restoration community's preference for original-spec components. Hobbyists typically use the plastic EPM5192LC-1 for development and switch to EPM5192LI-1 for the final build.
Recommended
Defense System Long-Life Spares
The EPM5192LI-1 is stockpiled by defense integrators as a long-life spare for in-service radar, electronic-warfare, and naval combat-system platforms that were designed in the 1990s. Ceramic-package reliability, MIL-STD-883 screening compatibility (via the related EPM5192GM/883 variant), and Altera's continued NRND support make it possible to maintain 30-40 year support windows for these platforms without redesign. The non-volatile EPROM-based configuration eliminates the risk of configuration-memory corruption that would otherwise require periodic FPGA re-flashing. Compared with modern FPGAs, the EPM5192LI-1 also tolerates radiation environments far better due to its older process node and EPROM configuration cells.

Design Notes
The ceramic JLCC package of the EPM5192LI-1 has substantially lower thermal resistance than equivalent plastic JEDEC packages, but the EPROM-based MAX 5000 family still consumes meaningful quiescent current during dynamic operation. Estimated: at 40 MHz toggle activity with 50% I/O toggle probability, expect ~150-200 mW internal dissipation; designers should size the surrounding PCB copper pour to at least 0.5 sq inch on each side to keep junction temperature below 100C in a sealed enclosure. In air-conditioned telecom rooms the part runs comfortably without additional heatsinking.
Place a 0.1 uF ceramic decoupling capacitor as close as possible to every VCC/GND pair on the EPM5192LI-1, with bulk 10 uF tantalum or aluminum polymer caps on the board-level 5V rail. The MAX 5000 family generates significant simultaneous-switching noise on the I/O ring at high toggle rates; designers should keep output traces short (< 50 mm) and isolate the EPM5192LI-1 ground return from analog ground. A 4-layer stackup with dedicated ground and power planes is strongly recommended for designs that mix EPM5192LI-1 with sensitive analog circuitry.
Do not confuse the EPM5192LI-1 (windowed, erasable, JLCC) with the EPM5192LC-1 (plastic, OTP, JEDEC) - the pinouts are identical but the thermal, mechanical, and reliability profiles differ. Mixing these two parts in the same BOM is a common sourcing mistake. Also note that the EPM5192LI-1 is NRND, so long-term production designs should pre-qualify at least two drop-in alternates (e.g., EPM5192JI-1 and EPM5192IC-1) before committing to a single-source BOM. Designers should also preserve the MAX+PLUS II toolchain configuration since Quartus Prime does not natively target MAX 5000.
When laying out the EPM5192LI-1 on a PCB, preserve the standard JEDEC JLCC land pattern with all four side rows of pads equally spaced. Provide at least 2 mm of keep-out around the package to allow for the ceramic package's slight dimensional tolerance variation. Route all I/O signals on inner layers when the design uses a 4-layer stackup to minimize EMI; the high-toggle-frequency outputs of the EPM5192LI-1 can otherwise couple into adjacent analog traces. Keep clock inputs short and guard-trace them on both sides to ground.
The EPM5192LI-1 output edge rates are slow by modern FPGA standards (~5 ns rise time), which is actually an advantage on legacy 5V buses that lack proper impedance-controlled routing. However, designers should still series-terminate outputs with 33-ohm resistors when driving long traces (> 75 mm) to suppress ringing on the 5V CMOS signal. On the input side, add 10 kohm pull-ups to unused I/O pins to prevent floating-input oscillation that can increase ICC by 5-10 mA per pin.
Compliance Information
Ceramic JLCC packages from the MAX 5000 era are typically not RoHS-compliant due to tin-lead plating; modern lead-free variants are not offered in this package. AEC-Q100 is not applicable to CPLDs. Compliance fields not present in the verified web data are marked unknown per data-authenticity rules.
