EPM5192ALI84-15 Overview
A Complex PLD (CPLD predecessor) is a non-volatile programmable logic device that combines multiple AND/OR macrocell arrays on a single die. The EPM5192 belongs to the MAX 5000 family - Altera's high-density, high-speed, UV-erasable/OTP CMOS PLD series positioned between classic PAL/GAL devices and modern MAX II CPLDs. Within the broader programmable logic taxonomy, this device sits in the hierarchy: macrocell-based PLD -> MAX 5000 family -> UV-erasable/OTP Complex PLD -> programmable logic -> semiconductor IC.
Key features of the EPM5192ALI84-15 include 192 logic macrocells, 7 dedicated input pins, 64 bidirectional I/O pins supporting up to 72 total input channels, propagation delay tPD of 25 ns (-15 speed grade), and CMOS non-volatile OTP programming via on-chip EPROM cells. The device is offered in industrial grade (-40C to +85C). The PQCC J-Lead package (JESD-30 S-PQCC-J84) is socket-compatible with standard PLCC-84 sockets, easing field replacement and programming-socket tooling.
Typical applications include legacy bus-interface glue logic in industrial controllers, address decoding and wait-state generation in 8/16/20 MHz microprocessor systems, replacement of discrete 7400-series TTL glue, and high-pin-count state-machine integration in through-hole assembly lines where modern BGA/QFP CPLDs are not pin-compatible. The OTP architecture is suitable for production-volume designs where design changes are infrequent.
Design consideration: confirm availability of compatible 84-pin PLCC programming sockets before PCB layout commit; modern CPLDs in fine-pitch QFP/BGA do NOT drop in. For new designs, consider MAX II or MAX V CPLDs as a migration path only if PCB layout can be changed.

Typical Applications
EPM5192ALI84-15 is suitable for 6 applications: Legacy Microprocessor Glue Logic, Industrial Controller Address Decoding, State Machine Integration, VMEbus / Multibus Interface Logic, 7400-Series TTL Replacement, Legacy Equipment Repair and Sustaining.
Legacy Microprocessor Glue Logic
The EPM5192ALI84-15's 192 macrocells and 25 ns propagation delay suit legacy 8/16/20 MHz microprocessor bus-interface glue logic. In systems using 80C186, 68k, or Z80 processors, it consolidates address decoding, wait-state generation, chip-select logic, and interrupt prioritization into a single 84-PLCC, replacing 5-10 discrete 74LS/74F PAL/GAL devices. The windowless OTP architecture is ideal for production units where the design is finalized - prototype builds can use the windowed LC84 variant for UV-erase iterations. The 72-input capacity accommodates the full 20-bit address bus plus control signals. Migration to modern MAX II/MAX V CPLDs is recommended for new designs requiring Flash reprogrammability.
Recommended
Industrial Controller Address Decoding
In industrial PLC and process-control backplanes, the EPM5192ALI84-15 provides reliable address decoding for I/O expansion modules and memory-mapped peripherals. The 192-macrocell capacity supports up to 192 independent chip-select or enable signals, while the 25 ns tPD maintains timing margin with ISA bus cycles (~120 ns minimum) and VMEbus. The industrial temperature grade (-40C to 85C) tolerates factory-floor environments. The 84-pin PQCC package is socket-compatible for field replacement in legacy installations - critical for industrial systems with 20+ year service lives where the original Altera PLDs must be replaced as they reach end-of-life. No cross-brand equivalent shares the 84-PLCC footprint.
Recommended
State Machine Integration
The EPM5192ALI84-15 is well suited to large state-machine integration in control panels, where multiple discrete TTL state machines need to be consolidated into one device. Each of the 192 macrocells can implement a registered state bit with combinatorial next-state logic, supporting FSMs with 50+ states and complex transition graphs. The OTP programming is appropriate for production units once the FSM is validated, while the 25 ns tPD enables state transitions at up to ~20 MHz. The 64 I/O pins interface directly to 5V logic. Designers should note that the OTP architecture prevents in-system reprogramming - design changes require a new programmed part, so prototype with the windowed LC84 variant before committing to OTP.
Recommended
VMEbus / Multibus Interface Logic
In VMEbus and Multibus backplane systems, the EPM5192ALI84-15 implements bus arbitration, interrupt acknowledge, and address-modifier decoding with timing that meets the 25 ns bus-signal requirements. The 192 macrocells support multiple parallel arbitration schemes, while the 7 dedicated inputs accept bus-grant and request signals. The PQCC-84 package and CMOS EPROM technology have proven reliability in long-lifecycle aerospace, defense, and industrial VME installations. For new VME designs, consider the MAX II EPM240 or MAX V EPM570, but for legacy VME backplane repair, the EPM5192ALI84-15 remains the original-fit part. The industrial temperature grade tolerates chassis-internal temperatures up to 85C.
Recommended
7400-Series TTL Replacement
The EPM5192ALI84-15 is a one-for-many replacement for 7400-series TTL glue logic in legacy through-hole designs. A single EPM5192ALI84-15 typically replaces 10-20 discrete 74LS/74F/74AS chips (decoders, multiplexers, latches, parity generators, comparators), reducing board area, power consumption, and BOM cost. The OTP programming is well-suited to designs where the glue logic is finalized and replicated across many production units. The 84-PLCC footprint fits on legacy boards designed around DIP-20/24 sockets with adapter boards. For new TTL-replacement designs, evaluate the EPM240 (MAX II) which provides similar density in a smaller TQFP-100 package with Flash reprogrammability.
Recommended
Legacy Equipment Repair and Sustaining
The primary modern use of the EPM5192ALI84-15 is sustaining engineering for legacy equipment with installed bases of 20+ years. Aerospace test equipment, military radios, industrial process controllers, and scientific instruments originally designed in the 1990s use this PLD as glue logic. When a unit fails in the field, a replacement programmed EPM5192ALI84-15 can be socketed in directly - the PQCC-84 form factor uses standard test-burn-in sockets available from 3M, Yamaichi, and Wells-CTI. Independent distributors (Jotrin, Microchip USA, FPGAkey) maintain limited stock. For new equipment, MAX II/MAX V CPLDs are the recommended replacement path, but the EPM5192ALI84-15 remains irreplaceable for legacy repair.

Key Differentiators
- Windowless OTP architecture suited for production volume (vs EPM5192ALC84-15)
- Industrial temperature grade for harsh environments (vs EPM5192ALC84-15)
- Faster -15 grade with full industrial qualification (vs EPM5192ALI84-20)
Design Notes
The EPM5192ALI84-15 is windowless OTP - once programmed it CANNOT be erased or reprogrammed. Always validate the JEDEC fuse map with a windowed EPM5192ALC84-15 (UV-erasable) prototype before committing to OTP volume production. Programming failures on OTP parts are permanent and the device is destroyed. Estimated prototype-to-production workflow: program LC84, UV-erase, iterate; once design is frozen, program LI84 for production.
The 84-pin PQCC (PLCC) J-Lead package uses standard 84-pin PLCC sockets (1.27 mm pitch). Recommended sockets include 3M 8400-series, Yamaichi IC149-084-£ series, and Wells-CTI 84-pin PLCC sockets. For field-replaceable designs, use a socketed footprint rather than direct PCB soldering to enable EOL replacement. Direct soldering of PLCC J-leads to PCB is feasible but complicates rework. The PLCC package is NOT pin-compatible with QFP/BGA modern CPLDs - any migration to MAX II/MAX V requires a complete PCB redesign.
The EPM5192ALI84-15 in industrial temperature grade operates from -40C to +85C ambient, with CMOS EPROM technology typical quiescent current of approximately 100-200 mA at 5V VCC depending on output switching activity. Estimated: at full 64 I/O switching at 5 MHz, dynamic current adds 30-50 mA. Provide at least 4 PCB VCC/GND decoupling capacitors (0.1 uF ceramic) placed within 5 mm of each package VCC pin to suppress switching noise on the EPROM programming lines and output banks. The PLCC package has moderate theta_JA (~40-50 C/W in still air); ensure adequate airflow in enclosed chassis.
Compliance Information
Compliance information not available in provided web data. The EPM5192ALI84-15 is a legacy Altera (now Intel) CMOS EPROM device from the 1990s; RoHS compliance for the LI84 suffix (industrial, OTP) was not confirmed in retrieved sources. Pre-2005 Altera products are commonly non-RoHS unless explicitly marked Pb-Free.
