Typical Applications
EPM5192LC-1 is suitable for 6 applications: Legacy 5V Bus-Interface Glue Logic, Industrial Control State Machines, Peripheral Address Decoding, Motor-Control Interface Logic, Military / Aerospace Sustaining Systems, Prototype Glue Logic Replacement.
Legacy 5V Bus-Interface Glue Logic
The EPM5192LC-1's 192 macrocells, 64 user I/O, and 5V-native CMOS I/O make it a direct replacement for clusters of 74F/74AS glue logic in legacy ISA, VME, and PC-104 bus systems. Placed between a CPU bus and peripheral ASICs, it handles address decoding, chip-select generation, wait-state insertion, and bus-cycle control in a single device. The 25 ns propagation delay supports 25-33 MHz bus clocks with comfortable margin, and the EPROM-based configuration boots instantly with no external memory. Unlike an FPGA, the EPM5192LC-1 needs no configuration PROM and starts running within nanoseconds of power-up, which is critical for legacy systems without host CPU reset stretchers.
Recommended
Industrial Control State Machines
Industrial PLCs, motor controllers, and process-control front-ends often use MAX 5000 CPLDs to implement deterministic state machines for sequencing I/O, fault handling, and interlock logic. The EPM5192LC-1's 192 macrocells fit several independent state machines plus combinational logic on one chip, and its 5V CMOS I/O interfaces directly to 5V optocouplers and 24V industrial backplanes through level shifters. The non-volatile EPROM configuration survives power cycles without external boot memory, making it robust in unattended field installations. The 0-70C commercial temperature grade is acceptable for enclosed industrial cabinets, while the EPM5192IC-1 industrial variant extends the range for harsher environments.
Recommended
Peripheral Address Decoding
The EPM5192LC-1 excels at peripheral address decoding in legacy embedded systems, where 8 or 16 address bits must be compared against fixed patterns to generate chip-selects for memory banks, I/O peripherals, and custom ASICs. Each macrocell can implement a 32-product-term decode equation, and 192 macrocells easily handle 30-40 chip-select outputs plus auxiliary control logic. The 7 dedicated inputs are typically used for chip-select qualifier signals (read/write, address strobe, DMA acknowledge), while 64 I/O pins drive the chip-select outputs and read-back status. Drop-in compatibility with the EPM5192LC-2 lets designers up-grade timing margin without PCB rework.
Recommended
Motor-Control Interface Logic
Stepper and BLDC motor controllers use the EPM5192LC-1 to generate commutator timing, PWM control signals, encoder decoding, and fault-interlock logic in a single CPLD. The 64 I/O pins can drive multi-axis stepper drivers (step, direction, enable per axis) or 3-phase inverter gate-driver signals with dead-time insertion implemented in macrocell equations. The 25 ns propagation delay supports PWM switching frequencies up to 1 MHz when combinational paths are kept short, and the EPROM configuration stores motor-control firmware without an external boot ROM. Ceramic-windowed variants are preferred for prototype development where the commutation table is iteratively refined.
Recommended
Military / Aerospace Sustaining Systems
The MAX 5000 family supports MIL-STD-883 screened variants (EPM5192GM/883) for military and aerospace systems where radiation tolerance, hermeticity, and traceable lot testing are mandatory. While the EPM5192LC-1 is the commercial plastic-LDCC variant, its 84-LDCC footprint is shared with the MIL-screened ceramic-windowed equivalents, enabling common PCB layout between prototypes and flight hardware. The EPROM-based configuration is intrinsically radiation-tolerant for SEU compared to SRAM FPGAs, making MAX 5000 CPLDs preferred for low-earth-orbit and short-duration missions. Sustaining legacy avionics and ground-vehicle systems is the primary application for the LC-1 plastic variant.
Recommended
Prototype Glue Logic Replacement
Design teams maintaining legacy hardware use the EPM5192LC-1 to consolidate scattered 74-series logic into a single programmable device, reducing PCB area and improving testability. The 192 macrocells can replace 15-25 standard SSI/MSI parts, and the 84-LDCC footprint fits within the same board real estate as several 20-pin SOIC packages. The EPROM configuration means firmware revisions require only a UV-erase and re-program cycle (ceramic variant) or OTP replacement (LC plastic), and JTAG-less programming via the Altera ByteBlaster is supported by the legacy MAX+PLUS II toolchain. Drop-in compatibility with the EPM5192LC-2 allows timing-margin upgrades without board rework.

- Industrial temperature grade in same footprint (vs EPM5192IC-1)
Design Notes
The EPM5192LC-1 requires a stable 5V supply in the range 4.75V to 5.25V; unlike later MAX 7000/Max II parts it has no 3.3V variant. Decouple each VCC pin (16, 42, 63) with a 0.1 uF ceramic capacitor placed within 5 mm of the package pin, and add a bulk 10-47 uF tantalum or aluminum electrolytic capacitor near the device. Estimated: total Icc at 50 MHz toggling is approximately 200-300 mA typical, so power-rail sizing must account for this dynamic current. The EPROM configuration means inrush current on power-up is minimal, but the 5V supply must still meet the 4.75V minimum under full transient load.
The plastic LDCC package is rated for 0C to +70C commercial operation; for extended-temperature applications use the EPM5192IC-1 industrial variant in the same 84-LDCC footprint. The ceramic windowed EPM5192GC-1 supports MIL-STD-883 screening for harsher environments. Estimated: at 300 mA Icc and 5V supply, total dissipation is roughly 1.5 W, well within the plastic LDCC's thermal budget with modest airflow. No external heatsink is required for typical commercial use.
The 84-LDCC package is a leaded ceramic chip carrier with through-hole or socket-compatible lead style depending on the LC (plastic) or GC (ceramic) variant. For prototypes, use a 84-pin LDCC socket to allow device removal and re-programming of the ceramic-windowed variant. For production, the plastic LDCC can be hand-soldered with care (leaded ceramic terminations) or wave-soldered at standard 5V leaded profiles. Avoid using Pb-free reflow profiles on the LC-1 variant because the terminations contain lead-bearing solder plating. Route signal traces on the inner PCB layers, keeping I/O traces short to minimize ringing on the 25 ns output edges.
Do NOT confuse the EPM5192LC-1 with the EPM5192JC-1 - the LC is plastic 84-LDCC while the JC is 84-PLCC, and the PCB footprints differ. Do NOT assume 3.3V tolerance - this is a 5V-only part, and applying 3.3V signals to its I/O will fail logic-threshold checks. Do NOT use modern Quartus toolchains to compile MAX 5000 designs - they require the legacy MAX+PLUS II software, which still runs on Windows XP and Win 7 but not natively on Win 10/11 (use a virtual machine). Do NOT omit bulk decoupling on VCC - the EPROM-based configuration draws dynamic current on every clock edge.
Compliance Information
LDCC package uses Pb-bearing ceramic terminations, making the EPM5192LC-1 RoHS non-compliant. For MIL-STD-883 screened ceramic variants, refer to the EPM5192GM/883 family which shares the same die and pinout.
