EPM5192LC-2N Overview
What is an EPLD? An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic IC that uses EPROM/EEPROM/flash cells to store the AND-OR logic pattern. EPLDs sit in the programmable-logic hierarchy below modern CPLDs and FPGAs, offering fast pin-to-pin combinational delay, deterministic timing, and simple JTAG/ISP programming. They are used for glue logic, address decoding, bus interfacing, state-machine implementation, and counter/timer functions in legacy designs. The MAX 5000 family is the classic Altera high-density EPLD line, predating the MAX 7000/MAX II CPLD families.
Key features include 192 logic macrocells, 192 flip-flops, programmable I/O architecture with up to 96 I/O pins (package-dependent), and a typical combinatorial propagation delay of 25 ns at the -2 speed grade. The device supports 5V tolerant inputs on legacy LC nodes, in-system programmability via Altera's programming hardware, and JTAG boundary-scan test per IEEE 1149.1. Power consumption is typical for the MAX 5000 family at 5V VCC.
The EPM5192LC-2N uses Altera's classic MAX architecture: a global Programmable Interconnect Array (PIA) that routes any macrocell output to any other macrocell input, giving a flat, predictable timing model. Each macrocell contains an AND-OR array feeding a configurable flip-flop, with programmable output polarity, clock, and feedback paths.
Typical applications include legacy industrial control systems, telecommunication backplane glue logic, address decoding and wait-state generation in 80C186/68k/8051 microprocessor designs, bus arbitration, peripheral interfacing, and replacement/maintenance of older Altera MAX designs. The part is also widely used as a retrofit upgrade for older UV-erasable PAL/GAL-based boards.
When designing with this part, ensure your target toolchain supports the legacy MAX 5000 device family (Altera MAX+PLUS II or compatible). Verify the speed grade is sufficient for the timing budget - the -2 (25 ns tPD) grade suits many asynchronous decoding and glue-logic paths but is too slow for high-speed synchronous buses.

Typical Applications
EPM5192LC-2N is suitable for 6 applications: Legacy Microprocessor Address Decoding, Industrial Control Glue Logic Replacement, Telecommunication Backplane Interfacing, State Machine and Counter Implementation, Peripheral Interface and Bus Arbitration, Legacy Avionics and Military Maintenance.
Legacy Microprocessor Address Decoding
The EPM5192LC-2N is well-suited for address decoding and wait-state generation in 80C186, 68k, 8051, and similar 16/32-bit legacy microprocessor designs. Its 192 macrocells provide ample AND-OR terms to decode full address spaces (e.g., 24-bit 68k = 16 MB) into 8 to 16 chip-select outputs, while the -2 speed grade (tPD approximately 25 ns) easily fits within typical 8 MHz to 25 MHz system clocks without wait states. Per Altera's MAX 5000 application notes, the global PIA lets the designer place the decoder macrocells anywhere on the device and route outputs to any pin, simplifying board layout. Compared to discrete 74LS138 / 74LS139 decoder trees, the EPM5192LC-2N consolidates what would otherwise be 8 to 16 decoder ICs into a single package, reducing board area, power consumption, and BOM cost in legacy retrofit designs.

Industrial Control Glue Logic Replacement
The EPM5192LC-2N is widely used as a drop-in consolidation part for legacy industrial PLC and process-control boards that originally used 10 to 30 PAL/GAL devices for glue logic. Its 192 macrocells can replace an entire board's worth of 20-pin PALs while preserving the deterministic, fixed-pin propagation delay of PAL-based designs. The ceramic LC package with UV window allows engineers to erase, re-program, and reuse the same physical part across multiple design iterations during prototyping and field maintenance. According to the Altera MAX 5000 datasheet, the device's commercial 0C to +70C operating range covers most factory-floor environments. Engineers retrofitting 1980s-1990s industrial controls frequently select the EPM5192LC-2N because the MAX+PLUS II toolchain and bitstream format are still archived, ensuring long-term maintainability of the legacy programming files.
Recommended
Telecommunication Backplane Interfacing
The EPM5192LC-2N fits telecom backplane glue-logic applications where bus arbitration, interrupt steering, and protocol conversion must be implemented with deterministic timing and high noise immunity. Its 192 macrocells easily handle the 8 to 16-bit bus steering logic common in T1/E1 multiplexer and cross-connect backplanes, and the 5V VCC operation provides strong drive and noise margin typical of legacy telecom central-office equipment. The -2 speed grade (tPD approximately 25 ns) accommodates the 4 MHz to 8 MHz backplane clock rates common in legacy TDM architectures. Per the Altera MAX 5000 datasheet, each macrocell's programmable output polarity and feedback path simplifies implementation of bidirectional bus transceivers and time-slot interchange functions. The LC ceramic package is rated for the long-lifecycle telecom deployment where field service may be required 15 to 25 years after manufacture.
Recommended
State Machine and Counter Implementation
The EPM5192LC-2N's 192 dedicated flip-flops make it ideal for implementing large multi-state controllers, sequence generators, and counter chains that would otherwise require multiple 74LS161/163/193 counter ICs. Each macrocell includes a configurable flip-flop with programmable clock, reset, and preset, and the global PIA allows state bits to feed directly into any combinational macrocell in the next clock cycle without external routing. According to the Altera MAX 5000 datasheet, complex state machines with 16 to 32 states can be implemented in a single device, including Mealy and Moore machines with multiple outputs and conditional transitions. Engineers designing legacy stepper-motor controllers, vending-machine sequencers, and elevator-floor controllers in the 1990s relied on the EPM5192 family for this exact reason, and the part remains in use today for maintenance of these deployed systems.
Recommended
Peripheral Interface and Bus Arbitration
The EPM5192LC-2N excels at peripheral-interface logic between legacy microprocessors and shared-resource peripherals such as dual-ported RAM, FIFOs, DMA controllers, and interrupt controllers. Its 192 macrocells provide sufficient capacity to implement multi-master bus arbiters (e.g., daisy-chain, parallel-priority, or rotating-priority schemes), wait-state generators for slow peripherals, and bus-width conversion bridges between 8-bit and 16-bit buses. Per the Altera MAX 5000 datasheet, the macrocell's tri-state output buffer control can be programmed on a pin-by-pin basis, simplifying bidirectional bus implementation without external transceivers. The deterministic 25 ns tPD of the -2 speed grade fits well within typical ISA bus and PC/104 timing budgets (8 MHz to 12 MHz), making the EPM5192LC-2N a common building block in legacy PC/104 industrial embedded modules still in production today.

Legacy Avionics and Military Maintenance
The EPM5192LC-2N and its military-grade sibling EPM5192GM-2 are commonly used as maintenance parts for legacy avionics, radar, and military-communication systems designed in the 1990s around the MAX 5000 family. The ceramic LC package with UV window enables re-programming in depot-level maintenance workflows where the original programming files are archived in the system's technical data package. Per MIL-STD-883 and the Altera military product catalog, the EPM5192GM-2 (the GM /883B variant of the same 192-macrocell die) supports the -55C to +125C military temperature range and is qualified for defense logistics. The EPM5192LC-2N itself is the commercial-grade version used in non-military variants of the same avionics platforms and in dual-use industrial-military systems where the full -55C to +125C range is not required. For new military designs, the GM/883B variant is mandatory.

Design Notes
The EPM5192LC-2N is obsolete and is no longer in continuous production as of 2026-09-12; design engineers should not select this part for new production designs. For new designs requiring 192 macrocells, evaluate modern alternatives such as Altera MAX II EPM240 or MAX V CPLDs, which offer in-system programmability, lower power, faster tPD, and 3.3V/2.5V I/O support at comparable or lower unit cost. The EPM5192LC-2N should be reserved for maintenance of legacy systems already in field deployment.
The LC package is a ceramic J-leaded chip carrier with a quartz UV window on top. Per the Altera MAX 5000 datasheet, the window allows erasure by exposure to UV light at 12 mW/cm-squared for 20 to 30 minutes. Designers should mount the device with the window facing upward, away from heatsinks or shadowing components. The ceramic body is brittle; avoid mechanical stress on the leads during PCB assembly and use sockets during prototyping to enable re-programming without re-soldering.
The EPM5192LC-2N operates from a single 5V VCC supply; per the Altera datasheet, the typical Icc is in the range of several hundred mA depending on the programmed logic utilization and switching activity. Decoupling capacitors should follow Altera's MAX 5000 reference design: a 0.1 uF ceramic bypass capacitor placed within 5 mm of each VCC pin, plus a single 10 uF tantalum or electrolytic bulk capacitor at the device's VCC entry point. Designers migrating to MAX II/MAX V should review the lower Icc (~50 mA typical) of the modern parts as a power-saving opportunity.
The MAX 5000 family requires the legacy Altera MAX+PLUS II toolchain (or a compatible third-party tool) for design entry, fitting, and programming-file generation. MAX+PLUS II was superseded by Quartus II starting with the MAX 7000 family; engineers unfamiliar with MAX+PLUS II may find the legacy EDA flow difficult to source. Confirm that your organization has archived copies of MAX+PLUS II and the appropriate programming hardware (e.g., Altera ByteBlaster or MasterBlaster) before committing the EPM5192LC-2N to a new design.
