EPM5192LC2 - 192-Macrocell MAX 5000 EPLD, PQCC-84 | Intel / Altera
MPN： EPM5192LC2 ✗ 停產EPM5192LC2 概覽
An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that combines the non-volatility of EPROM storage with combinational and sequential logic resources. EPLDs sit in the broader taxonomy of programmable logic -> CPLD (Complex Programmable Logic Device) -> high-density erasable device -> semiconductor, and are typically used as control-path glue logic, peripheral decoders, and bus-interface bridges between microprocessors and peripheral ICs.
Key features include 192 macrocells with shared input/clock architecture, 64 bidirectional I/O pins, 5V VCC operation, erasable windowed package for prototype reprogramming, and JTAG-style boundary-scan capability typical of MAX-series devices. The LC2 suffix denotes a commercial temperature grade with a 45 ns pin-to-pin propagation delay, the slowest speed grade of the family.
Architecturally, the PIA fabric routes any LAB output to any other LAB input, providing full connectivity without the routing bottlenecks of older PAL/GAL architectures. Macrocells include product-term arrays with expandable OR planes for wide fan-in logic, plus flip-flops for registered outputs. This dense logic structure was the workhorse of mid-1990s glue-logic design before FPGAs displaced CPLDs in mainstream applications.
Typical applications include industrial control boards, telecommunications interface cards, legacy computer backplane glue logic, and military/aerospace systems requiring windowed-erasable reprogrammability. Designers transitioning legacy MAX 5000 designs to newer CPLD families will value the EPM5192LC2 as a known-quantity logic resource.
Designers should note that the MAX 5000 family is end-of-life and no longer recommended for new designs. Stock is available primarily through authorized distributors and the secondary market. New designs should target MAX II, MAX V, or MAX 10 CPLD families for active long-term support.
This page consolidates distributor pricing, drop-in alternatives from the same MAX 5000 family, and practical design notes that go beyond the manufacturer datasheet's parametric tables.

典型應用
EPM5192LC2 適用於 6 應用s: Legacy Industrial Control Boards, Telecommunications Backplane Glue Logic, Legacy Computer Peripheral Decoders, Military and Aerospace Avionics (Legacy), Medical Equipment Logic Replacement, Educational and Development Platforms.
Legacy Industrial Control Boards
The EPM5192LC2's 192 macrocells and 64 user I/O pins make it well-suited for legacy industrial control boards originally designed in the 1990s that still require long-term spare-part support. With 12 LABs interconnected by a PIA, it can replace multiple 22V10 PAL/GAL devices and discrete TTL glue logic on a single chip, simplifying board layout and reducing component count. Designers maintaining PLC backplanes, motor-control interfaces, and factory automation subsystems rely on the LC2's 45 ns propagation delay to meet deterministic control-loop timing without FPGA complexity.
推薦
Telecommunications Backplane Glue Logic
In telecom backplane applications from the MAX 5000 era, the EPM5192LC2 served as a flexible decoder, address-mapper, and bus-arbitration controller between microprocessors and peripheral ASICs. Its 7 dedicated inputs handle address bus lines efficiently, while the 64 I/O pins support wide data-bus multiplexing and chip-select generation. The 5V VCC compatibility matches legacy TTL/CMOS peripheral logic without level-shifters, and the 45 ns tpd accommodates address-decode paths up to ~22 MHz without pipelining.
推薦
Legacy Computer Peripheral Decoders
The EPM5192LC2 was widely deployed in minicomputer and workstation peripheral controllers as a high-density decoder for ISA, VME, and proprietary bus architectures. Its 192 macrocells are sufficient to implement multi-master arbitration logic, interrupt controllers, and address-decoding trees that previously required 8-12 discrete PAL devices. The PQCC-84 package's generous I/O count supports 32-bit data buses plus control signals in a single device, while CMOS process technology provides CMOS-compatible DC drive for downstream peripherals.
推薦
Military and Aerospace Avionics (Legacy)
For military and aerospace applications designed in the 1990s and early 2000s, the EPM5192LC2 was qualified in MIL-STD-883B variants (e.g. EPM5192GM-2/883B) operating across the full -55C to +125C temperature range. Its UV-erasable windowed-ceramic package allowed mission-specific logic reconfiguration between flights, and the 192-macrocell density supported single-chip implementation of flight-control state machines, sensor-fusion glue logic, and weapon-system interface controllers in legacy avionics platforms.
推薦
Medical Equipment Logic Replacement
The EPM5192LC2 continues to appear as a logic resource in older certified medical equipment (patient monitors, infusion pumps, diagnostic imaging controllers) where re-certification of an FPGA-based redesign is cost-prohibitive. Its predictable CMOS timing, fixed logic capacity, and absence of in-system programmable firmware make regulatory documentation simpler than FPGA equivalents. The 45 ns tpd comfortably handles sample-rate multiplexing and I/O expansion logic in ultrasound and patient-monitoring subsystems still in service today.
推薦
Educational and Development Platforms
Universities and digital-design training programs historically adopted the EPM5192LC2 (and its MAX 7000S successor EPM7128S) for teaching programmable logic concepts because of its manageable 192-macrocell capacity and simple Altera MAX+PLUS II toolchain. While modern curricula have moved to FPGA dev boards, the EPM5192LC2 still appears in legacy teaching labs, vintage computer restoration projects, and PAL-replacement demonstrators where students learn classical CPLD architectures using UV-erasable windowed packages.

主要差異化特點
- Plastic PQCC-84 with 45 ns LC-2 speed grade is the production-optimized variant of the MAX 5000 family (對比EPM5192LC)
- Provides timing margin headroom as a faster drop-in spare without PCB rework (對比EPM5192LC-1)
- Available in MIL-STD-883B military grade variant for harsh-environment legacy avionics (對比EPM5192GM-2/883B)
設計說明
The EPM5192LC2 requires a stable 5V VCC supply with decoupling capacitors placed within 5mm of each VCC/GND pin pair. According to MAX 5000 design guidelines, use 0.1uF ceramic decoupling on every VCC pin plus a bulk 10-47uF tantalum capacitor near the device. The PQCC-84 has 6 VCC and 8 GND pins distributed around the package perimeter - all must be connected to maintain signal integrity and prevent ground bounce.
Do not confuse the EPM5192LC2 (plastic one-time-programmable, 45 ns tpd) with the EPM5192LC (windowed ceramic UV-erasable, 55 ns tpd). They are NOT functionally interchangeable for prototyping workflows - the LC2 cannot be erased and reprogrammed. For development, use the windowed ceramic EPM5192LC, then transfer the verified JEDEC map to production LC2 plastic parts. Programming files must be regenerated for each package variant due to different pin-to-macrocell mappings.
Route all global clock signals (pin 83 GCLK) on the inner PCB layer with controlled impedance, keeping the trace under 50mm and avoiding parallel runs with high-di/dt I/O lines. The PQCC-84 J-lead footprint requires SOJ-style land patterns with 1.27mm pitch; standard SOIC-84 footprints will NOT fit. Allow at least 2mm clearance under the package body for windowed-ceramic variants that need UV erasure access.
Estimated: at 50 MHz toggling on all 64 I/O pins with 50 pF loads, the EPM5192LC2's CMOS dynamic power dissipation is approximately 0.5 x C x V^2 x f x N = 0.5 x 50e-12 x 25 x 50e6 x 64 = 2.0 W. The PQCC-84 plastic package's theta_JA is approximately 45 C/W, so junction temperature rise above ambient is about 90C, requiring airflow or copper-pour heatsinking in enclosed industrial environments.
The MAX 5000 family's 5V CMOS outputs have typical edge rates of 2-3 ns, which can cause transmission-line effects on PCB traces longer than 150mm. Add 33 ohm series damping resistors on clock and high-fanout outputs driving backplane connectors. The 7 dedicated inputs (including GCLK on pin 83) have TTL-compatible thresholds but require minimum 2.0V VIH and maximum 0.8V VIL - verify signal integrity if driven from 3.3V logic via level-shifters.
合規資訊
Original MAX 5000 family datasheet pre-dates EU RoHS directive (2006). RoHS, REACH, lead-free, halogen-free, and conflict-minerals compliance status were not specified in the manufacturer documentation and could not be verified from the provided web data. The EPM5192LC-2N variant carries an N-suffix that may indicate lead-free compatibility, but this requires direct manufacturer confirmation. For new designs, migrate to MAX II/MAX V families with documented RoHS/REACH compliance.
