Typical Applications
EPM5192AQI100-20 is suitable for 6 applications: Legacy Industrial Bus Interface, Address Decoding and Chip-Select Generation, Custom Peripheral and State-Machine Controller, Glue-Logic Consolidation in Long-Lifecycle Products, Microprocessor-to-Peripheral Bus Bridge, Test and Measurement Front-End Logic.
Legacy Industrial Bus Interface
The EPM5192AQI100-20's 192 macrocells and 64 I/O lines make it well-suited to legacy industrial bus-interface bridges (e.g., ISA, PC/104, custom backplanes). It can absorb multiple 74-series glue-logic packages into a single CMOS EPLD, reducing board area and improving noise margins. Industrial temperature grade (-40 to 85 C) per the "I" suffix and 20 ns propagation delay comfortably meet the timing requirements of 8- and 16-bit bus cycles at legacy clock rates. Place the EPM5192AQI100-20 between the microprocessor bus and peripheral devices to consolidate address decoding, wait-state generation, and interrupt steering. Use the 7 dedicated inputs for high-fanout clock and control signals to preserve macrocell resources for logic.
Recommended
Address Decoding and Chip-Select Generation
The EPM5192AQI100-20 is frequently used as a dedicated address decoder and chip-select generator for multi-bank memory and peripheral subsystems. Its 192 macrocells easily handle the full address map of a 16- or 24-bit system, replacing dozens of 74LS138 / 74LS139 decoders. With 20 ns propagation delay the device fits within standard memory-access cycles without inserting wait states. The 100-pin PQFP package exposes enough I/O for both the address bus and the individual chip-select outputs to memory banks, ROM, and I/O peripherals. Designers can lock the resulting pinout via the MAX+PLUS II fitter and reuse the JEDEC file across product revisions.
Recommended
Custom Peripheral and State-Machine Controller
Use the EPM5192AQI100-20 to implement a custom peripheral controller where each of the 192 macrocells encodes one slice of a large finite-state machine or datapath sequencer. The deterministic LAB/PIA timing guarantees worst-case 20 ns state transitions, which simplifies verification compared with SRAM-based FPGAs of similar vintage. The PQFP-100 footprint is large enough to expose all state outputs to external actuators or indicators. Industrial temperature rating supports factory-floor enclosures without additional derating. Pair the EPM5192AQI100-20 with a microcontroller that handles the high-level protocol while the EPLD handles deterministic bit-level sequencing.
Recommended
Glue-Logic Consolidation in Long-Lifecycle Products
The EPM5192AQI100-20 is widely deployed as a single-package replacement for tens of SSI/MSI 74-series TTL parts in long-lifecycle products such as medical instruments, test equipment, and aerospace subsystems. Erasable CMOS EPROM technology lets the factory program each unit while still allowing field rework with a UV eraser and EPROM programmer. With 64 bidirectional I/O pins plus 7 dedicated inputs, the device has ample headroom for even dense glue-logic nets. The industrial temperature grade and PQFP-100 footprint fit the existing qualified BOMs of many legacy programs. Where field-returns must be repairable for decades, the established MAX 5000 supply chain is preferable to newer CPLDs with shorter support windows.
Recommended
Microprocessor-to-Peripheral Bus Bridge
Bridge an older microprocessor bus to a modern peripheral by routing data, address, and control signals through the EPM5192AQI100-20. With 192 macrocells and 64 I/O pins, the part can implement multiplexers, latches, and protocol converters in one device instead of multiple 74-series buffers. The 20 ns propagation delay adds minimal latency to memory or peripheral accesses, preserving throughput. Industrial temperature operation allows deployment in unattended outdoor cabinets and factory automation cells. Designers can field-update the bridge logic by erasing the EPROM and reprogramming with a new MAX+PLUS II JEDEC file.
Recommended
Test and Measurement Front-End Logic
The EPM5192AQI100-20 is well-suited to the front-end logic of bench-top and rack-mount test equipment, where it can multiplex sensor inputs, gate trigger signals, and drive displays. The 192 macrocells comfortably handle parallel data-acquisition state machines and timing generators, while the 64 I/O pins interface directly to ADC/DAC channels and front-panel switches. With 20 ns timing, the EPLD keeps up with typical 1-10 MSPS converter rates. Industrial temperature operation supports equipment that operates in non-climate-controlled labs. The PQFP-100 footprint also aids thermal dissipation in convection-cooled instruments.

Key Differentiators
- Industrial temperature grade for harsh environments (vs EPM5192AQC100-20)
- Balanced speed/power for legacy 8-16 bit systems (vs EPM5192AQI100-15)
- Drop-in compatibility with other MAX 5000 PQFP-100 variants (vs Modern MAX II CPLD EPM570T100C5N)
Design Notes
Estimated: When porting an EPM5192AQI100-20 design to MAX II or MAX V, do not assume pin-to-pin compatibility. The MAX II family uses a different package (typically TQFP-100 or BGA), a different JTAG-based ISP interface, and a different logic-element architecture (LUT-based versus MAX 5000's product-term macrocells). Migration requires re-running the original VHDL/Verilog or schematic through the Quartus II compiler with a MAX II library, plus PCB rework for the new package. Plan for a full re-characterization, not a socket swap.
The EPM5192AQI100-20 is a CMOS EPROM device and draws substantially higher quiescent current when erased or unprogrammed than when fully programmed with typical logic patterns. Always program the device before bench-testing power consumption, or expect to see elevated ICC values that may exceed the datasheet maximum. Decouple VCC with at least one 0.1 uF ceramic capacitor placed within 5 mm of each VCC/GND pair, plus a bulk tantalum or electrolytic cap of 10-22 uF on the supply rail per the MAX 5000 design guidelines.
The PQFP-100 package (R-PQFP-G100) has gull-wing leads on 0.635 mm pitch, which is well within the capability of standard SMT lines but requires careful reflow profile control to avoid coplanarity issues. Provide at least 6 mm of clearance around the package for inspection and rework. For long-lifecycle industrial designs, specify a lead-free or tin-lead finish explicitly when ordering, and confirm that the distributor's reels match the assembly house's process. Pin 1 orientation follows the standard PQFP convention (dot or bevel at pin 1).
Place the EPM5192AQI100-20 close to the bus drivers and memory/peripheral devices it interfaces to, minimizing stub lengths on high-speed control signals. Use a dedicated ground plane under the device to control switching noise; the PIA's programmable routing can otherwise pick up crosstalk on long parallel traces. Keep clock and dedicated inputs short and shielded by ground traces. Avoid routing noisy switching signals (e.g., from DC-DC converters) directly under the PQFP-100 footprint.
Compliance Information
RoHS, REACH, lead-free and halogen-free status are not stated in the verified web data for this obsolete part; original MAX 5000 family datasheets predate widespread RoHS documentation. The "I" suffix confirms industrial operating temperature, but is not an AEC-Q100 automotive qualification. Verify compliance with the supplier before placing orders for new product builds.
