Typical Applications
EPM5192AQC-2 is suitable for 6 applications: Legacy ISA / VME Bus Decoding, Industrial Control Glue Logic, Address Mapping & Chip-Select Generation, Power-Up State Machine Replacement, Long-Life-Cycle Aerospace / Military Avionics, Prototype / Education Logic Development Board.
Legacy ISA / VME Bus Decoding
The EPM5192AQC-2's 192 macrocells, 64 user I/O lines and deterministic 45 ns propagation delay make it a strong fit for legacy ISA and VME peripheral bus decoding, where it can replace multiple 74-series TTL glue-logic chips with a single non-volatile device. Placed between the bus address lines and the peripheral chip-select inputs, the CPLD decodes the address map and generates chip-select strobes with predictable timing that does not vary with logic utilization, which is essential for legacy bus timing budgets. Unlike SRAM-based FPGAs the EPM5192AQC-2 powers up in a known state with no boot PROM, simplifying system bring-up. Its OTP switch matrix retains the decoded logic configuration indefinitely, ideal for long-life-cycle industrial boards.
Recommended
Industrial Control Glue Logic
In industrial control platforms the EPM5192AQC-2 provides the deterministic glue logic that ties microprocessors, sensors and actuator drivers together, replacing dozens of 74HC/74LS gates with a single re-programmable (during development) non-volatile CPLD. The 192 macrocells can typically implement a full state-machine plus parallel I/O mapping, while the 64 user I/O pins provide ample headroom for mixed 5V/3.3V interfacing. The MAX 5000 family's CMOS process and wide supply tolerance suit the noisy 24V industrial bus environment when paired with external TVS and bulk decoupling. The OTP/UV-erasable switch matrix ensures the logic configuration survives power-down cycles typical of factory equipment.
Recommended
Address Mapping & Chip-Select Generation
The EPM5192AQC-2 is well suited for centralized address mapping and chip-select generation in microprocessor-based boards, where it can decode a 24-bit or 32-bit address bus into multiple peripheral chip-select strobes with a single device. The 192 macrocells can implement several independent chip-select decoders plus a wait-state generator, while the 7 dedicated inputs can carry clock, read/write and burst strobes that bypass the LAB logic for low-latency paths. With 45 ns tPD on the -2 grade the device easily fits into 25 MHz address-pipeline cycles, and the deterministic pin-to-pin timing guarantees consistent strobe placement regardless of how many decoders are mapped. The R-PQFP-G100 package gives 64 user I/Os - typically far more than the address bus alone requires, leaving room for additional control logic.
Recommended
Power-Up State Machine Replacement
Replacing discrete PAL/GAL power-up sequencers, the EPM5192AQC-2 boots in a known state and drives deterministic reset, clock-enable and power-good signals to downstream ASICs, FPGAs and microprocessors. The 45 ns tPD is more than adequate for the millisecond-scale reset sequencing typical of multi-rail systems, and the 192 macrocells leave plenty of headroom for additional supervisory logic such as watchdog timers and brown-out detectors. Because the switch matrix is OTP (non-volatile), the sequencing code lives with the hardware - no configuration memory to fail or corrupt. The MAX 5000 family's 5V-tolerant I/Os also simplify interfacing with legacy supervisory devices.
Recommended
Long-Life-Cycle Aerospace / Military Avionics
The MAX 5000 family's mature CMOS process, established Altera/Intel long-term support, and OTP non-volatility make the EPM5192AQC-2 a common choice for long-life aerospace and military avionics platforms that require deterministic behavior and supply-chain stability. The 192 macrocells cover typical interface-bridging, MIL-STD-1553 bus monitoring, and ARINC 429 line-receiver tasks, while the 7 dedicated inputs can be routed directly to high-priority interrupts. Windowless AQC packaging delivers the rugged hermetic-ish PQFP construction favored in avionics, and the legacy -2 speed grade is widely available on the broker market for sustaining engineering. Designers must still validate derating against the target environment, since the AQC grade is typically specified for commercial temperature.
Recommended
Prototype / Education Logic Development Board
Universities and design-training labs continue to use the EPM5192AQC-2 on legacy MAX 5000 development boards because the device's 192 macrocells and 64 I/Os offer enough capacity for full processor designs, while the JTAG (IEEE 1149.1) programming interface works with the legacy MAX+PLUS II toolchain that is still freely available for educational use. Students can implement RISC processors, peripheral controllers and bus interfaces in a single 100-pin PQFP, then debug with logic analyzers on the breakout-friendly gull-wing package. The 45 ns tPD provides realistic timing experience that maps to modern MAX II/MAX V devices when students transition to industry-grade designs. Re-programming requires UV-erase of a windowed variant (JM/JI) or fresh OTP devices, which is a useful teaching moment about non-volatile logic.

Key Differentiators
- Deterministic 45 ns tPD with no in-system speed variability (vs SRAM-based FPGAs of similar density)
- Non-volatile OTP switch matrix - no boot PROM required (vs EPM5192AQC-1 (slower speed grade sibling))
- 100-pin PQFP (R-PQFP-G100) - 64 user I/Os at 0.635 mm pitch (vs EPM5192AJC84-20 (84-pin PLCC package, smaller I/O count))
Design Notes
Allocate a 100-pin PQFP land pattern with 0.635 mm pitch on the PCB; keep at least 2 mm of trace clearance around the package perimeter to ease inspection and rework. Place a 0.1 uF ceramic decoupling capacitor within 3 mm of every VCC/GND pair, plus a single 10 uF tantalum or ceramic bulk capacitor near the package supply pins. For high-toggle-count nets (clocks, JTAG) use 50 ohm controlled-impedance traces and series-termination resistors at the driver to suppress ringing on the gull-wing lead stubs.
AQC-suffix packages are windowless and OTP - they CANNOT be UV-erased after programming. Pre-production verification must be done on a windowed JM/JI variant (e.g., EPM5192AJM84-20) or on a development board before committing the design to AQC production parts. Also note the -2 speed grade is the SLOWER grade (-1 is faster); ensure you order the correct speed bin for the timing budget, as the markings differ only in the trailing dash number and are easy to confuse on the reel label.
Route the JTAG signals (TDI, TDO, TMS, TCK) as a daisy-chain with no stubs, and place a 4.7 kohm pull-up on TCK and TMS to keep the boundary-scan state machine in a known state during power-up. Keep the JTAG chain length below 150 mm to avoid signal-integrity issues at the typical 10 MHz TCK frequency, and provide a JTAG header on the PCB for in-system programming. Reserve one user I/O pin as a 'done' or 'configuration-valid' flag so the rest of the system can handshake against the OTP configuration at power-up.
Estimated: at typical CMOS switching activity (~30% of 192 macrocells toggling at 25 MHz, 5V supply), the EPM5192AQC-2 dissipates approximately 0.6 W. The PQFP-100 package typically exhibits theta_JA near 50 C/W on a standard 4-layer JEDEC test board, so junction temperature rise above ambient would be roughly 30 C - well within the commercial 70 C limit at 25 C ambient. In enclosed industrial enclosures with restricted airflow, derate the system by adding a small copper heatsink pad or thermal vias beneath the exposed paddle region (if present on the variant).
Compliance Information
Compliance fields marked unknown because the verified web data did not explicitly list RoHS, REACH, lead-free or halogen-free status for the EPM5192AQC-2. The MAX 5000 family was produced during the pre-RoHS and RoHS-transition eras, so leaded and lead-free finishes may both be encountered depending on date code. AEC-Q100 is not applicable because the EPM5192AQC-2 is a commercial-grade legacy CPLD.
