Typical Applications
EPM5192AQM100-20 is suitable for 6 applications: ISA / Legacy 8/16-bit Bus Address Decoding, Peripheral Glue Logic in Industrial PLCs, Glue Logic for Microprocessor Memory Interfacing, State Machine and Sequencer Controllers, Legacy Board Repair and Obsolete-Component Replacement, Prototype Development for Embedded Control.
ISA / Legacy 8/16-bit Bus Address Decoding
The EPM5192AQM100-20 fits ISA-bus and 8/16-bit microcontroller address-decoding applications because its 33 ns tPD easily satisfies the 8 MHz ISA bus cycle timing (125 ns per cycle) and provides sub-2 ns setup margin even with two cascaded decoder stages. With 192 macrocells the device can implement 8-16 independent chip-select or enable decoders across a 16- or 24-bit address space, replacing multiple discrete 74LS138/139/151/688 devices. The 64 user I/O lines are sufficient to drive 16 chip selects plus 16 read/write strobes plus control glue, and the deterministic PIA-based timing means design iteration is not required to close timing. Recommended companion parts: 74HC245 bus transceivers, 74HC573 latches, 80C188/80C186 microcontrollers.
Recommended
Peripheral Glue Logic in Industrial PLCs
The EPM5192AQM100-20 is well suited to industrial PLC peripheral glue logic where deterministic timing, non-volatile configuration, and high I/O count in a single package simplify BOM. Its 64 I/O pins can replace 8-12 discrete 74-series logic packages implementing watchdog timers, peripheral chip selects, encoder quadrature decoding, PWM generation, and opto-isolator interface conditioning. The 12 LABs of 16 macrocells each can host multiple independent state machines running at up to 66.7 MHz, supporting encoder decoding up to 2 MHz input frequency after 4x decode. JTAG/IEEE 1149.1 boundary-scan simplifies production board test for PLC backplanes. Recommended companions: 24V-to-5V digital isolators, encoder interface ICs, RS-485 transceivers.
Recommended
Glue Logic for Microprocessor Memory Interfacing
The EPM5192AQM100-20 handles memory-interface glue logic for 8/16/32-bit microprocessor systems, generating chip selects for SRAM, DRAM, Flash, and boot ROM from a single address decoder. With 33 ns tPD the device fits comfortably between the processor address latch (e.g., 74HC573) and memory access time, eliminating 2-4 discrete PAL/GAL devices. Its EPROM-based non-volatile configuration survives power cycles without boot PROM, simplifying board layout. The 64 I/O count supports 8-12 independent chip selects plus RAS/CAS/WE generation for DRAM controllers in cost-sensitive designs. Recommended companions: 74HC573 address latches, AS7C4096 SRAM, 28F256 Flash memory.
Recommended
State Machine and Sequencer Controllers
The EPM5192AQM100-20 implements complex multi-state sequencer controllers with deterministic step transitions thanks to its PIA-based interconnect and 33 ns tPD timing. Designers can host 6-12 independent Moore or Mealy state machines in the 192 macrocells, with each machine running at the full 66.7 MHz external clock for high-speed instrumentation or motor-control sequencing. The non-volatile EPROM configuration is critical for safety sequencers that must power up in a known state, unlike SRAM-based FPGAs that require boot time. JTAG boundary-scan enables in-system verification of all state-machine outputs. Recommended companions: 74HC151 data selectors, HCTL-2022 quadrature counters.
Recommended
Legacy Board Repair and Obsolete-Component Replacement
The EPM5192AQM100-20 serves as a drop-in repair part for legacy boards originally designed with MAX 5000 CPLDs, where the original part has failed and no in-production equivalent shares the PQFP-100 footprint. Its identical pinout to other EPM5192 PQFP-100 variants (AQI, AQC) makes it a true solder-compatible substitute. For boards designed in the 1990s - early 2000s using MAX+PLUS II flows, the design files recompile directly to this device. Broker-sourced stock from authorized obsolete distributors such as 1-Source Components and Sourcengine supports long-tail repair demand. Recommended companions: JTAG programmers supporting MAX 5000, PLCC-to-PQFP socket adapters for test fixtures.
Recommended
Prototype Development for Embedded Control
The EPM5192AQM100-20 supports prototype development of embedded control logic where engineers need deterministic timing and instant-on configuration without FPGA toolchain complexity. Its 192 macrocells and 64 I/O provide enough headroom to host an entire custom peripheral controller - SPI master, UART, PWM block, GPIO expander - as a single chip alongside the main microcontroller. The 33 ns tPD fits common 25-50 MHz SPI and UART bit-banging budgets. EPROM-based configuration means prototype boards boot into the programmed state immediately, accelerating iteration cycles. Recommended companions: ATmega328 microcontrollers, MAX232 level translators, 74HC04 clock buffers.

Key Differentiators
- Sole MAX 5000 variant with 33 ns tPD in commercial PQFP-100 grade (vs EPM5192AQM100-15)
- Commercial temperature grade vs industrial (vs EPM5192AQI100-20)
- Plastic PQFP package vs alternate package grades (vs EPM5192AQC100-20)
Design Notes
The 100-pin PQFP package (R-PQFP-G100, 0.65 mm pitch typical, body approx 20 x 14 mm) requires a 4-layer PCB with continuous power and ground planes to meet the MAX 5000 family decoupling and EMI requirements. Place one 0.1 uF ceramic decoupling capacitor adjacent to every VCC/GND pair (typically 4-6 pairs for this package), plus a 10 uF tantalum or aluminum bulk capacitor within 25 mm of the device. Route all 64 user I/O signals on the top layer with matched lengths if any signals exceed 50 MHz toggle rate, and reserve the inner stripline layers for power distribution. The exposed die-pad thermal pad (if present on this package variant) must be soldered to a copper pour for thermal relief even at modest CMOS power levels.
Do not confuse the EPM5192AQM100-20 (commercial plastic PQFP, 33 ns) with the EPM5192AQI100-20 (industrial PQFP) or EPM5192AQM100-15 (commercial, 25 ns tPD) - the suffix letters encode temperature grade and speed grade and are not interchangeable for industrial or timing-critical designs. The PQFP package is one-time programmable (windowless); design changes require a new physical part. Engineers migrating from MAX+PLUS II to Quartus should verify that legacy .pof or .jed files recompile correctly against the current device library, as some macrocell attributes changed between tool versions.
Although the MAX 5000 PIA interconnect gives deterministic, routing-density-independent 33 ns tPD, the I/O pins still exhibit CMOS output-edge rates around 1-2 ns that can cause transmission-line effects on traces longer than approximately 50 mm or above 25 MHz toggle rates. Add 22-33 ohm series damping resistors on clock and high-speed output nets if ringing exceeds 10% of VCC swing. Keep the JTAG TCK signal short and well-terminated to avoid programming failures. The 7 dedicated inputs are optimized for clock and asynchronous clear distribution and have lower input-capacitance than I/O pins - use them for global signals.
Compliance Information
Compliance status for EPM5192AQM100-20 not explicitly stated in the verified web data; the part is an obsolete Altera (now Intel) MAX 5000 family CPLD originally designed in the 1990s. The 'M' suffix historically denotes commercial plastic PQFP grade, which pre-dates RoHS - assume legacy SnPb finish unless the manufacturer product page explicitly states lead-free. AEC-Q100 is not applicable for commercial-grade programmable logic.
