EPM5192GM/8883 - MAX 5000 192-Cell UV PLD 55ns | Altera CPGA-84
The Altera EPM5192GM/8883 is a high-density, UV-erasable programmable logic device (PLD) from the MAX 5000 family, providing 192 macrocells in a ceramic windowed 84-pin Pin Grid Array (CPGA-84) package. According to the Altera MAX 5000 datasheet, this device delivers pin-to-pin delays as fast as 55 ns with counter frequencies up to 76.9 MHz, 3,750 usable gates, and is fabricated on a 0.75-micron CMOS process optimized for high-speed combinatorial and registered logic implementations. The MAX 5000 family is part of the broader category of programmable logic devices, which sit hierarchically between fixed-function logic ICs and full FPGA/CPLD architectures. A programmable logic device (PLD) is a semiconductor whose logic function is defined after manufacture by the end user, allowing designers to integrate tens to hundreds of SSI/MSI logic gates into a single package. The MAX 5000 series occupies the high-density end of Altera's classical PLD portfolio, offering the highest logic-to-pin ratio of any general-purpose PLD family in its era, with 600 to 3,750 usable gates and JTAG-compatible in-system programmability on most members. The /8883 suffix indicates MIL-STD-883 screening for high-reliability military and aerospace applications. Key features include 192 macrocells, 55 ns maximum propagation delay (tPD), 76.9 MHz maximum counter frequency (fCNT), and a 100% factory-tested CMOS architecture with TTL-compatible I/O. The device supports a 5V nominal VCC operation and provides bidirectional I/O pins with programmable output enable. The ceramic windowed CPGA-84 package allows laboratory UV erasure and reprogramming, ideal for prototype development and low-volume military programs. Typical applications include military and aerospace digital systems, replacement of multiple TTL/CMOS SSI/MSI gate arrays, high-speed state machines, address decoders, bus arbitrators, and counter/divider chains where non-volatility through UV erasure is preferred over OTP. The /8883 MIL-STD-883B screening makes this variant particularly suitable for avionics, missile guidance, and ruggedized industrial control. When designing with the EPM5192GM/8883, note that the ceramic CPGA-84 package requires a through-hole PGA socket or soldered pin array on the PCB. The quartz window enables UV erasure at 12,000 uW-sec/cm² integrated intensity for 30 to 45 minutes, after which the device can be reprogrammed using an Altera PLAD-MAX logic programmer. Designers should provide adequate ESD handling and avoid prolonged direct sunlight exposure that could erase the configuration. Static-sensitive handling precautions per JEDEC JESD625-A are mandatory.

The Intel (formerly Altera) EPM5192GM883B is a high-speed, high-density CMOS EPLD (Erasable Programmable Logic Device) from the MAX 5000 family, organized as 192 macrocells with 7 dedicated inputs and 64 user I/O lines. The /883B suffix indicates MIL-STD-883 Revision B processing for defense and aerospace programs, and it is housed in a square 84-terminal Ceramic Pin Grid Array (CPGA) package measuring 28.45 mm, with a 5V nominal VCC. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic component that combines the architectural flexibility of a PLD with on-chip macrocell logic. It sits in the broader taxonomy: programmable logic -> CPLD -> EPLD -> PLD -> semiconductor IC. MAX 5000 family devices use UV-erasable EPROM cells to retain configuration, providing instant-on behavior without external boot memory and making them well suited for legacy MIL/aerospace and industrial control designs. Key features of the EPM5192GM883B include a maximum clock frequency of 33.3 MHz, a propagation delay of 55 ns (tpd), and 192 macrocells fabricated in a CMOS process. The CPGA-84 package provides a hermetic ceramic enclosure rated for the extended military temperature range, supporting through-hole PCB mounting with high mechanical reliability. Architecturally, the device uses a classic MAX-style AND/OR programmable array with each macrocell containing a programmable flip-flop, product-term steering, and an I/O control block. The 64 I/O pins are arranged on the CPGA pin grid for balanced routing density. EPROM-based non-volatile storage means the device powers up instantly in the last programmed configuration - critical for avionics and weapons-system hardware where boot-time determinism is mandatory. Typical applications include avionics flight-control interfaces, military communications and signal-conditioning logic, industrial automation controllers, and legacy system retrofits. Engineers typically choose the EPM5192GM883B when a program mandates MIL-STD-883B processing and a hermetic CPGA package. Compared with modern flash-based CPLDs, the device is slower (33.3 MHz / 55 ns) but offers mature, long-life silicon with proven reliability in defense platforms. For new designs the EPM5192GM883B is generally not recommended; consider the pin-compatible MAX 5000 commercial/industrial variants or modern Altera/Intel MAX II or MAX V CPLDs in non-hermetic packages. When retrofitting a board, confirm the existing PCB accepts the CPGA-84 through-hole footprint and that the JTAG/ISP programming toolchain supports legacy MAX 5000 devices. This page consolidates distributor pricing, drop-in /883B and speed-grade alternatives, and practical design notes not found in the original 52-page Altera datasheet alone, giving engineers a single reference for sourcing and second-sourcing decisions.
EPM5192GM883B-2 - 192-Macrocell UV PLD 45ns | Intel / Altera MAX 5000
The Altera (now Intel) EPM5192GM883B-2 is a 192-macrocell UV-erasable Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, featuring a 45 ns propagation delay and housed in an 84-pin ceramic Pin Grid Array (CPGA) package. It is built on a 5 V CMOS process and operates over the commercial supply range typical of the MAX 5000 series, with seven dedicated inputs and sixty-four user I/O lines forming the boundary-scan-capable JTAG/I/O subsystem. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on digital logic device that combines multiple PLA-style macrocell blocks on a single chip with a programmable interconnect fabric. In the broader taxonomy, the CPLD sits below FPGAs in density, above discrete 74-series logic in integration, and is typically used for glue logic, bus interfacing, state-machine decoding, and boot-loader bridges where deterministic propagation delay and <100 ns pin-to-pin response matter more than raw gate count. The defining features of the EPM5192GM883B-2 are its 192 macrocells (each containing a programmable AND/OR array and a flip-flop), 45 ns worst-case pin-to-pin propagation delay (-2 speed grade), 33.3 MHz maximum internal clock frequency, and 5 V nominal VCC. The 'GM883' suffix denotes a ceramic CPGA package rated to MIL-STD-883 environmental and reliability conditions, while the '-2' indicates the second (faster) speed bin. Together, these attributes place the part in the high-reliability / military temperature range targeting defense and aerospace programs. Architecturally, the device organizes its 192 macrocells into multiple Logic Array Blocks (LABs) interconnected by a programmable switch matrix, with seven dedicated input pins feeding every LAB to minimize input skew. The 5 V CMOS process yields high noise margin and TTL-compatible I/O, which is essential when the part is used as a 5 V bus bridge in legacy mixed-voltage systems. Typical applications include 5 V bus arbitration logic in VMEbus and MIL-STD-1553 backplanes, military and aerospace control subsystems, legacy peripheral glue for Motorola 68000 and Intel x86 CPU boards, deterministic state-machine controllers, and industrial control where UV-reprogrammability and JAN-qualified packaging are procurement requirements. The 45 ns tPD also makes it suitable for slow-but-deterministic address decoding where an FPGA would be overkill. When designing with this part, note that the 'GM883' CPGA package requires a through-hole PGA socket (PGA-84) and a socket extraction tool; reflow soldering is not an option. Designers must also budget the UV-erase cycle (typically 30-60 minutes of 12,000 uW/cm² UV exposure at 253.7 nm) and provision a top-of-package quartz window in the production enclosure if in-system reprogramming is anticipated. This page consolidates distributor pricing, drop-in equivalents, and application notes for the EPM5192GM883B-2 that go beyond the legacy MAX 5000 datasheet, helping engineers validate long-term availability and source military-grade alternates.
EPM5192IC-1 - 192-Macrocell MAX 5000 PLD | Altera | 5V
The Altera EPM5192IC-1 is a 192-macrocell member of the classic MAX 5000 high-speed, high-density CMOS Erasable Programmable Logic Device (EPLD) family, supplied in an industrial-grade temperature range and a surface-mount J-lead ceramic package. It provides up to 3,750 usable gates, 7 dedicated inputs, and 64 I/O pins, with pin-to-pin propagation delays as fast as 15 ns and internal counter frequencies reaching 76.9 MHz, enabling glue-logic replacement, state-machine consolidation, and bus-interface decoding in legacy 5V systems. An EPLD is a non-volatile, UV-erasable programmable logic device that sits between simple PLAs and modern CPLDs in the programmable logic hierarchy (PLA -> EPLD -> CPLD -> FPGA). The MAX 5000 architecture combines a programmable AND/OR logic array with a flexible macrocell output structure, giving designers more usable logic per pin than older PAL/GAL devices while retaining the deterministic timing of array-based logic. It belongs to the broader semiconductor category of programmable logic devices and is still valued in long-life industrial and aerospace systems where 5V tolerance, predictable timing, and non-volatile configuration are required. Key features include 192 macrocells backed by a global interconnect with predictable delay paths, 0.5 ns interconnect resolution, and per-macrocell registers that can be configured as D, T, JK, or SR flip-flops. Output macrocells support programmable slew rate, open-drain output, and user-defined tri-state control. The device is in-system programmable via a JTAG/IEEE 1149.1 interface and offers built-in boundary-scan testability, with security-bit protection for design confidentiality. Operating from a single 5 V (4.75-5.25 V) supply with a -40C to +85C industrial temperature range, it draws roughly 300 mA Icc at maximum toggle rates. Typical applications include address decoding and wait-state generation in 80C186/80C51/Motorola 68k systems, bus-interface arbitration, state-machine consolidation replacing multiple 74LS/74F devices, and peripheral control logic in embedded computing. The EPM5192IC-1 is also used in industrial control boards, avionics, and military equipment where the -1 speed grade, ceramic J-lead package, and industrial temperature qualification deliver the ruggedness required for harsh environments. When designing with this part, plan the JTAG chain and ISP programming access before laying out the PCB; the JTAG pins (TDI, TDO, TMS, TCK) must be brought to a test header. Decouple VCC with a 0.1 uF ceramic and a 10 uF tantalum capacitor placed within 25 mm of each VCC pin to keep the internal logic-array switching currents from corrupting sensitive analog rails nearby.
EPM5192JC - 192-Macrocell Classic CPLD | Intel / Altera
The Intel / Altera EPM5192JC is a Classic-series Complex Programmable Logic Device (CPLD) from the EPM5192 family, delivering 192 macrocells organized into 12 Logic Array Blocks (LABs) and interconnected through a Programmable Interconnect Array (PIA), packaged in a 68-pin PLCC (JC) windowed ceramic carrier for UV-erase reprogrammability. It belongs to the broader MAX-class erasable programmable logic family, originally introduced by Altera (now part of Intel) for glue-logic, bus-encoding, and state-machine consolidation in industrial, telecom, and military designs. A CPLD (Complex Programmable Logic Device) is a non-volatile, deterministic-latency programmable logic device that combines multiple PAL-like macrocell blocks on a single die. The hierarchy runs: macrocell -> LAB (Logic Array Block) -> CPLD -> programmable logic -> semiconductor. Compared to FPGAs, CPLDs offer instant-on operation, predictable timing, and high drive strength, making them ideal for system-level glue logic, address decoding, and I/O expansion. The EPM5192JC features 192 macrocells, 12 LABs, and a PIA-based interconnect fabric that delivers consistent pin-to-pin propagation delays across all logic paths. Its UV-erasable windowed ceramic package enables multiple design iterations during prototyping, while the CMOS EPROM-based architecture provides non-volatile configuration retention without an external boot PROM. Programmable I/O architecture supports flexible voltage interfacing. Typical applications include bus-interface bridging, address decoding and chip-select generation in microprocessor systems, state-machine implementation, glue logic for ASIC replacement, and legacy industrial-control retrofits. The EPM5192JC's deterministic timing also suits real-time control loops and synchronous interface adaptation. When designing, consider the propagation delay budget, macrocell utilization per LAB, and I/O standard compatibility. The ceramic JC package is suited for development and military applications where UV reprogrammability is required; for production, plastic JI/JC variants or JTAG-programmed equivalents are typically preferred. This page synthesizes distributor availability, cross-reference alternatives, and practical selection guidance not found in the original Altera datasheet, supporting both new designs and legacy maintenance scenarios.
EPM5192JC-1 - 192-Macrocell UV CPLD, 40ns, 5V | Altera MAX 5000
The Altera EPM5192JC-1 is a 192-macrocell UV-erasable, One-Time-Programmable (OTP) Complex Programmable Logic Device (CPLD) from the classic MAX 5000 family, housed in an 84-pin Ceramic Quad Flat Pack (CQFP, JEDEC code S-CQCC-J84) and operating from a single 4.75 V to 5.25 V rail with a 40 ns propagation delay and a 62.5 MHz maximum internal toggle frequency. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that combines multiple macrocells with a centralized AND-Plane/OR-Plane architecture, providing deterministic pin-to-pin timing ideal for glue logic, address decoding, bus interfacing, and state-machine replacement. CPLDs sit below FPGAs in the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> digital IC -> semiconductor) and above discrete 22V10/PAL devices in functional density, offering between 32 and 512 macrocells per chip with predictable timing that does not depend on routing congestion. Key features of the EPM5192JC-1 include 3,750 usable gates, 192 macrocells, 84 user I/O pins, a programmable I/O architecture with per-pin output enable, JTAG-less ISP-friendly configuration via the classic Altera MAX programming interface, and CMOS low-power operation. The ceramic-windowed (J) package supports laboratory UV erasure, while the -1 speed grade delivers 40 ns tPD and 62.5 MHz fMAX over the commercial 0 C to +70 C temperature range. Architecturally, the device uses an EPROM-based macrocell array, which makes the configuration non-volatile and instantly available at power-up without external boot memory - a key advantage over SRAM-based FPGAs in deterministic-startup applications. The wide AND-Plane feeds a shared OR-Plane, and each macrocell contains a programmable flip-flop, XOR control, and a tri-state output buffer with per-pin enable. The 5 V CMOS I/O interfaces directly to TTL logic and to 5 V microprocessors without external level shifters. Typical applications include 5 V microprocessor bus decoding (8086, 68000, Z80 glue logic), peripheral control and address-latch replacement, industrial control and instrumentation, legacy telecom line-card logic, and aerospace/military designs that benefit from the radiation-tolerant ceramic package and the documented MIL-883B process flow. The ceramic J-package is favored in military and space-grade programs where plastic packages are not acceptable. When designing with the EPM5192JC-1, plan for the MAX+PLUS II or legacy MAX+PLUS development flow, allow a 5 V VCC supply with 100 nF/10 uF decoupling near the package, and remember that the ceramic windowed package must be erased under a UV lamp before reprogramming - which is why most production designs migrate to the plastic one-time-programmable (OTP) suffix variants once the design is frozen.

EPM5192JC-1N - 192-Macrocell CPLD, 40ns, 84-Pin CQFP | Altera
The Altera EPM5192JC-1N is a 192-macrocell Complex Programmable Logic Device (CPLD) from the MAX 5000 family, packaged in an 84-pin Ceramic Quad Flat Pack (CQFP, JEDEC JESD-30 code S-CQCC-J84) and specified for industrial-grade CMOS operation at 4.75V to 5.25V. It delivers a pin-to-pin propagation delay of 40 ns and supports clock frequencies up to 62.5 MHz, with 3.75K usable gates, 192 macrocells, 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), 64 user I/O lines, 7 dedicated inputs, and one external clock input. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EPROM/UV-erasable programmable logic device that sits hierarchically below FPGAs in the programmable logic taxonomy: programmable logic -> CPLD/FPGA family -> MAX-class CPLD -> MAX 5000 sub-family. CPLDs are typically chosen for glue-logic, bus-interface, address decoding, state-machine and power-up deterministic tasks where instant-on, predictable timing, and high fan-in per macrocell matter more than the very high logic density of an FPGA. Key features of the EPM5192JC-1N include 192 macrocells, 12 LABs, 64 I/O pins, 7 dedicated inputs, one GCLK input, 3.75K usable gates, 40 ns tPD, 62.5 MHz fMAX, in-system programmability via JTAG, and a 5V CMOS core. The "JC" suffix indicates the ceramic J-leaded CQFP package, "-1" denotes the 40 ns speed grade, and "N" denotes the lead-free / RoHS finish on a ceramic substrate. Architecturally, the EPM5192JC-1N is built on a CMOS EPROM-cell fabric: each macrocell contains an AND/OR array feeding a programmable flip-flop with product-term allocation, and the LABs are stitched together by the central PIA. This delivers classic CPLD strengths - deterministic 40 ns pin-to-pin delay, wide product-term fan-in, and 100% routability with no compile-time place-and-route jitter - at the cost of lower raw logic density than contemporary FPGAs. Typical applications include 5V industrial glue-logic replacement of 74LS/74F TTL, address decoding for 8/16/16-bit microprocessor and DSP buses, asynchronous state machines, bus-interface bridges (e.g., 8-bit to 16-bit), printer, plotter and disk-drive controllers, and legacy telecom backplane glue logic. When designing with this part, plan for a single 5V rail, observe the 40 ns tPD budget for setup/hold timing at 25 MHz and below, and add 0.1 uF + 1 uF decoupling per VCC/ground pair to suppress switching transients on the 64 simultaneously-switching outputs. This page synthesizes distributor pricing, verified drop-in and same-package alternatives drawn from the EPM5192/MAX 5000 family, and practical design notes - including a verified package-pinout check for the 84-pin CQFP - that are not consolidated on the manufacturer datasheet alone.
EPM5192JC-2 - 192-Macrocell UV PLD, 45ns, 84-Pin CQCC | Altera
The Altera EPM5192JC-2 is a UV-erasable programmable logic device (PLD) from the MAX 5000 family, integrating 192 macrocells organized into 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). Packaged in an 84-pin ceramic CQCC (J-lead) windowed package, the device offers up to 64 user I/O lines with 7 dedicated inputs and 1 external clock input, all routed through the PIA fabric. Key parameters include a 45 ns propagation delay (tPD) and a maximum clock frequency of 40 MHz, with a CMOS process providing low static power consumption. A UV-erasable Programmable Logic Device (UV PLD) is a non-volatile, reprogrammable integrated circuit that stores combinational and sequential logic in EPROM-style memory cells, which the user clears by exposing the die through a quartz window to ultraviolet light. In the broader system taxonomy, UV PLDs sit at the foundation of programmable logic: they preceded modern CPLDs and FPGAs, offering modest logic density, deterministic timing, and instant-on operation. Although newer SRAM-based FPGAs dominate high-density applications, UV PLDs like the EPM5192JC-2 remain valued for low-density glue logic in legacy military, aerospace, and industrial systems where the deterministic timing and one-time-programmed/UV-reprogrammed security model are advantages. Key differentiating features include the 192-macrocell density (one of the largest in the MAX 5000 generation), 84-pin ceramic CQCC package suitable for harsh-environment and military temperature grades, and the UV-erase window enabling prototype iteration cycles. The PIA routing fabric provides predictable interconnect delays, and the device is fully supported by the legacy Altera MAX+PLUS II development environment for schematic, VHDL, and Verilog entry. The EPM5192JC-2 uses an EEPROM/EPROM-style macrocell architecture where each macrocell contains a programmable AND/OR array, a flip-flop, and an output enable control. Combinational logic is realized as sum-of-products terms across the PIA, while sequential logic is captured in dedicated D-flip-flops per macrocell, allowing designers to implement state machines, address decoders, and bus interface logic in a single chip. Typical applications include military and aerospace systems (radar signal processing, avionics bus arbitration), industrial control glue logic, address decoding and interrupt management in VMEbus and Multibus backplanes, legacy system replacement where original MAX 5000 parts are no longer available, and educational or research platforms demonstrating UV-erase programmable logic workflows. The ceramic 84-pin CQCC package supports extended-temperature and Mil-Std-883B screening. When designing with the EPM5192JC-2, verify that the target board layout accepts the ceramic CQCC J-lead package and that designers have access to a UV eraser (typically 254 nm, ~30 minutes at 12 mW/cm²) for reprogramming. Programming requires a compatible EPROM-style PLD programmer and the legacy Altera MAX+PLUS II toolchain. For new designs, consider modern EEPROM-based MAX II or MAX V CPLDs that offer in-system programmability without the UV-erasure step. This page consolidates distributor pricing, legacy stock availability, drop-in alternative MPNs from the MAX 5000 family, and practical design notes that are not present in the original Altera datasheet, making it useful for sustainment engineers maintaining long-lifecycle military and industrial platforms.
EPM5192JC-ES - 192-Macrocell MAX 5000 CPLD, PLCC-84 | Intel / Altera
The Intel / Altera EPM5192JC-ES is a 192-macrocell Complex Programmable Logic Device (CPLD) from the classic MAX 5000 family, packaged in an 84-terminal PLCC (JEDEC S-CQCC-J84, J-lead ceramic chip carrier) suitable for surface mounting. The device integrates 12 Logic Array Blocks (LABs) interconnected via a Programmable Interconnect Array (PIA), delivering high-speed, high-density programmable logic in a footprint that has been a workhorse of telecom, industrial control, and military designs for more than two decades. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EPROM-based programmable logic device that combines the simplicity of PAL/GAL architecture with the density of an FPGA. It belongs to the broader hierarchy of programmable logic ICs, sitting between simple SPLDs and high-density FPGAs. CPLDs are typically chosen for glue logic, bus interfacing, state-machine control, and fast deterministic I/O tasks where predictable timing, instant-on behavior, and high drive strength matter more than raw gate count. The MAX 5000 family represents the second-generation Altera CPLD architecture with enhanced routing density and improved speed-power trade-offs. Key features of the EPM5192JC-ES include 192 macrocells, 12 LABs connected by a global PIA, EPROM-based configuration memory (one-time programmable), CMOS technology, and a J-lead PLCC-84 ceramic package rated for industrial and military operating conditions. The ES suffix indicates an enhanced specification screening level, typically indicating an industrial or military temperature range. The ceramic PLCC-84 package provides robust mechanical reliability for harsh environments and is hermetically compatible with legacy sockets. From an architecture standpoint, the EPM5192 family is a UV-erasable, EPROM-based CPLD with non-volatile configuration retained without external memory. Logic is implemented through a macrocell fabric of product-term arrays feeding a configurable register, and signals are routed through the central PIA to provide uniform, predictable delays regardless of placement. This deterministic timing is one of the key reasons MAX 5000 CPLDs remain in long-lifecycle military and industrial platforms. Typical applications include industrial control logic, telecommunications interface glue, military and avionics systems, parallel bus arbitration, address decoding for microprocessors, and state-machine-driven I/O expansion. The ceramic 84-pin PLCC package also makes this part well suited to legacy retrofits and defense systems requiring hermetic packaging. When designing with this part, ensure your programmer supports the MAX 5000 family (e.g., Altera/Intel MAX+PLUS II or a compatible third-party programmer). The ES-grade temperature specifier should be cross-checked against the specific sub-variant ordering code, and ceramic PLCC sockets should be used for prototyping to allow device erasure and replacement.

EPM5192JC1 - MAX 5000 CPLD 192-Macrocell 5V 62.5MHz | Intel
The Intel (formerly Altera) EPM5192JC1 is a high-density, UV-erasable CMOS Complex Programmable Logic Device (CPLD) from the MAX 5000 family, providing 3,750 usable gates and 192 macrocells in a 5 V pin-compatible architecture. It is packaged in a 68-pin ceramic J-lead CERQUAD (windowed) configuration per the MAX 5000 family datasheet, and operates from a single 5 V supply with 192 logic macrocells organized as 24 LABs of 8 macrocells each. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that combines multiple PAL-like AND/OR array blocks on a single chip, retaining its configuration without external memory. CPLDs sit hierarchically below FPGAs and above simple PLDs/GALs in the programmable-logic taxonomy, and are widely used as 'glue logic' to implement bus decoding, state machines, address mapping, and high-speed control logic where deterministic propagation delay and instant-on behavior are required. Key features of the EPM5192JC1 include 192 macrocells, 3,750 usable gates, 100% TTL-compatible I/O, 62.5 MHz maximum operating frequency, and a typical propagation delay of 25 ns per macrocell. It supports in-system programming via the JTAG-compatible Altera programming interface and includes user-programmable I/O architecture. The device is fabricated in 0.5 µm CMOS with EPROM cells, making it UV-erasable and one-time-programmable for windowed packages. The MAX 5000 architecture uses a Programmable Logic Array (PLA) structure with each macrocell containing a programmable AND array followed by an OR/Exclusive-OR gate and a configurable flip-flop. This gives every macrocell identical timing, simplifying static-timing closure and enabling deterministic worst-case delay analysis - a defining advantage over early FPGAs. Typical applications include address decoding for x86 microprocessor systems, bus interface logic (ISA/PCI bridges), peripheral controllers in industrial machines, state-machine controllers, and glue logic in telecom switching equipment. Engineers select the EPM5192JC1 when deterministic timing and instant-on behavior matter more than raw logic density. Designers should note that this part is in the MAX 5000 family and operates from a 5 V supply only - it is not 3.3 V tolerant on I/O. Programming requires either the original Altera programming hardware with a parallel-port JTAG dongle or a third-party programmer supporting the MAX 5xxx protocol; legacy software is Altera MAX+PLUS II (legacy) rather than modern Quartus. This page synthesizes distributor pricing, drop-in alternatives from the same MAX 5000 family, and practical design notes for legacy-system support not consolidated on the original Altera datasheet PDFs.
EPM5192JC2 - 192-Macrocell MAX 5000 CPLD, 45ns, PLCC-68 | Intel / Altera
The Intel / Altera EPM5192JC2 is a high-density, high-speed Complex Programmable Logic Device (CPLD) from the MAX 5000 family, integrating 192 macrocells and 12 Logic Array Blocks (LABs) interconnected through a Programmable Interconnect Array (PIA). It is housed in a 68-pin Plastic Leaded Chip Carrier (PLCC-68, package code "JC") and operates at a maximum clock frequency of 50 MHz with a pin-to-pin propagation delay (tPD) of 45 ns, identified by speed grade "-2". A Complex Programmable Logic Device (CPLD) is a non-volatile, flash- or EPROM/UV-erasable logic device that combines multiple PAL/GAL-like macrocells with a centralized interconnect matrix. In the system hierarchy, a CPLD sits between simple SPLDs (PAL/GAL) and large FPGAs: it offers deterministic timing, instant-on behavior, and a single-chip solution for glue logic, bus decoding, state machines, and address mapping. The MAX 5000 family was Altera's second-generation high-density CPLD line, fabricated in CMOS, and is widely regarded as one of the workhorse eras of 5-V programmable logic. Key features of the EPM5192JC2 include 192 macrocells (equivalent to roughly 6000 usable gates), 12 LABs, a Programmable Interconnect Array, one dedicated global clock input with shared input/clock capability on user I/O pins, support for up to 64 user I/O lines plus dedicated inputs, and CMOS process technology. The "-2" speed grade denotes the faster bin within the EPM5192 family (45 ns tPD vs 55 ns for the un-suffixed part). Programming is performed via a JTAG-style or dedicated Altera programming interface using a Master Programmer or ByteBlaster, with UV-erase versions requiring a quartz window for reprogramming. Architecturally, each macrocell contains a programmable AND/OR array feeding a flip-flop with selectable polarity, and the LABs are stitched together by the PIA for predictable, fixed-delay signal routing. This deterministic timing model is the defining advantage of CPLDs over SRAM-based FPGAs and is the reason MAX 5000 parts remain in service for legacy industrial, telecom, and military systems where predictable propagation delay and instant-on power-up are mandatory. Typical applications include bus-interface and address-decoding glue logic in 5-V VME/PCI backplanes, state-machine controllers in industrial PLCs, peripheral-interface adapters (Centronics, SCSI, GPIB), and replacement of multiple discrete PAL/GAL devices to reduce board area. The PLCC-68 package is socket-compatible with standard PLCC sockets, simplifying field replacement and production programming. When designing with this part, note that the MAX 5000 family uses 5-V tolerant I/O on most variants and consumes higher quiescent current than later MAX 7000/MAX II devices; for new designs engineers are generally steered toward MAX II or MAX V, but the EPM5192JC2 remains the correct choice for maintaining installed-base equipment.

EPM5192JC68 - MAX 5000 192-Macrocell EPLD | Altera | 68-Pin J-Lead
The Altera EPM5192JC68 is a 192-macrocell high-density, high-speed EPLD (Erasable Programmable Logic Device) from the classic MAX 5000 family, housed in a 68-pin PLCC (J-Lead) package. It provides non-volatile CMOS erasable programmable logic with 192 logic macrocells, 12 dedicated input pins, and 4 JTAG/I/O pins for a total of 76 user I/O pins, and is specified for commercial 0C to 70C operation. What is an EPLD? An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the architecture of a traditional PLD with the density of early FPGAs. The MAX 5000 family sits at the bottom of the programmable-logic hierarchy: macrocell -> EPLD -> CPLD family -> programmable logic -> semiconductor. EPLDs retain configuration in on-chip UV-erasable EPROM, allowing repeated reprogramming during development, and combine AND/OR array logic with a flexible interconnect matrix for glue-logic, state-machine, and bus-interface applications. Key features include 192 macrocells, a programmable interconnect array, 4 dedicated clock inputs, 16 expander product terms for shared logic, and a pin-compatible migration path to the higher-density MAX 7000 family. The device is in-system programmable via the Altera MAX+PLUS II / Quartus legacy toolchain, with JTAG-style boundary-scan test support. The J-Lead PLCC-68 socket-compatible footprint allows easy prototyping on standard 68-pin PLCC sockets. The EPM5192JC68 implements a second-generation MAX architecture with a programmable logic array feeding 192 macrocell blocks, each containing a programmable flip-flop and a configurable sum-of-products array. CMOS EPROM configuration cells provide non-volatile storage and high-density integration, achieving deterministic 35 ns pin-to-pin logic delays with predictable timing independent of routing. Typical applications include legacy bus-interface glue logic, address decoding, state-machine controllers, and pin-compatible upgrades for older discrete-74LS logic boards. Industrial process controllers and telecom backplane glue logic are common end uses. Aerospace, defense, and long-lifecycle programs continue to specify this part for proven reliability. When designing, confirm the 68-pin J-Lead socket (PLCC-68) is available and provide clean +5V power with proper decoupling. Note that this part is mature; new designs should validate long-term supply availability through franchised distributors. This page synthesizes distributor pricing, legacy cross-references, and design notes that go beyond the original Altera datasheet to assist engineers maintaining or repairing MAX 5000 designs.
EPM5192JC84-1 - 192-Macrocell UV CPLD, 40ns | Altera
The Altera EPM5192JC84-1 is a 192-macrocell UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, packaged in an 84-terminal Ceramic Chip Carrier (CQCC84/J84) and specified for a commercial operating grade. According to the EPM5192 family datasheet, it offers a worst-case propagation delay of 40 ns, 192 logic macrocells, and operates from a single 4.75 V to 5.25 V supply, delivering the high-density, high-speed glue-logic integration that defined the MAX 5000 series. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device built from multiple PAL-like macrocell blocks interconnected by a central programmable switch matrix. CPLDs sit in the broader taxonomy of programmable logic devices alongside SPLDs, FPGAs, and PALs, offering deterministic timing, predictable I/O behavior, and zero-configuration power-up that make them ideal for address decoding, bus interfacing, state-machine control, and peripheral bridging functions. Key features of the EPM5192JC84-1 include 192 macrocells of logic capacity, 40 ns worst-case pin-to-pin propagation delay, a wide 5 V ±5 % supply tolerance, and an 84-terminal J-lead ceramic surface-mount package with high-reliability thermal characteristics. CMOS EPROM-based configuration cells provide one-time-programmable (OTP) operation in production, while the UV window variant supports laboratory and prototype erasure. The architecture delivers combinational and registered logic with programmable interconnect, allowing designers to consolidate multiple 74-series MSI/SSI packages into a single device. Architecturally, the device is built on Altera's CMOS EPROM process with a classic AND-OR array feeding individual product-term allocators per macrocell, a structure that yields deterministic, data-sheet-guaranteed timing independent of routing congestion. Because the configuration is stored in non-volatile EPROM cells, the EPM5192JC84-1 functions as a true instant-on logic device with no boot PROM or in-system programming controller required. Typical applications include legacy 5 V address decoding, glue logic between microprocessors and peripherals, asynchronous state machines, and bus-interface adapters in industrial and instrumentation equipment. When designing with this part, note that ceramic CQCC84 packages are surface-mountable but require careful thermal profiling and that the UV-erasable variant must be exposed to UV light for ~20 minutes before reprogramming.
EPM5192JI - 192 Macrocell MAX 5000 EPLD | Altera | 84-Pin PLCC
The Altera EPM5192JI is a 192-macrocell high-speed, high-density UV-erasable CMOS Programmable Logic Device (PLD) from the MAX 5000 family, housed in an 84-pin PLCC package and operating from a single 4.75V to 5.25V supply with a nominal 5V rail. According to the Altera EPM5192 datasheet, the device provides 192 macrocells, 64 user I/O lines, and 7 dedicated inputs organized into 12 interconnected Logic Array Blocks (LABs), giving a per-macrocell propagation delay of approximately 55ns and a toggle frequency in the tens-of-MHz range typical of the MAX 5000 generation. A UV-erasable CMOS EPLD is a type of Erasable Programmable Logic Device built on a non-volatile EPROM cell technology that can be erased by exposing the package window to ultraviolet light. EPLDs sit in the broader hierarchy: programmable logic > PLD > EPLD > CMOS EPLD, and the MAX 5000 family was Altera's high-density generation of the early-to-mid 1990s, positioned between simple PALs and the later, more capable MAX 7000/MAX 9000 families. The EPM5192JI is intended for glue-logic integration, decoder/encoder consolidation, and state-machine replacement in industrial and telecom equipment. Key features include 192 macrocells, 12 LABs, 64 bidirectional I/O pins, 7 dedicated inputs, 55ns pin-to-pin propagation delay (tpd), and 100% PCI-compliant bus interfaces for 5V systems. The architecture uses a programmable AND/OR array feeding each macrocell, with per-macrocell flip-flops, individually-programmable I/O architecture, and JTAG-less in-system programmability through the older MAX 5000 programming algorithm. The device is fabricated in a 5V CMOS EPROM process that requires a windowed ceramic package (the JI suffix indicates a windowed PLCC) for erasure. Typical applications include 5V PCI bus interfaces, glue-logic consolidation, custom state machines, address decoding for microprocessor systems, and bus-width adaptation in industrial controllers. The wide fan-in and shared LAB expander pools give predictable timing suitable for synchronous control logic. When designing with the EPM5192JI, leave adequate clearance around the package window for UV erasure (windowed parts only) and respect the 4.75V-5.25V supply tolerance specified in the Altera datasheet to avoid programming-margin issues during ISP.
EPM5192JI-1 - 192-Macrocell MAX 5000 PLD | Intel / Altera
The Intel / Altera EPM5192JI-1 is a high-density, high-speed CMOS UV-erasable programmable logic device (PLD) from the classic MAX 5000 family, delivering 192 macrocells, 64 user I/O lines plus 7 dedicated inputs, and a 55 ns propagation delay in a 84-pin ceramic/Windowed J-lead (JLCC) package. It is designed for 5 V systems, operates from 4.5 V to 5.5 V, and uses 12 interconnected Logic Array Blocks (LABs) arranged in the classic MAX architecture. The '-1' speed grade designates the slowest of the EPM5192 family grades, prioritizing density and low cost over maximum toggle rate, while the 'JI' suffix indicates the industrial-temperature ceramic JLCC package. The device is one-time or UV-erasable rather than in-system programmable, making it suitable for mature production designs that are no longer expected to change but require high logic density at the lowest unit cost. A Programmable Logic Device (PLD) is an integrated circuit whose logic function is defined by on-chip configuration rather than fixed wiring. Within the programmable logic hierarchy, the EPM5192JI-1 sits in the 'high-density PLD' category, between small SPLDs (PAL/GAL) and modern FPGAs. The MAX 5000 family uses a CMOS EPROM cell to store the fuse map, giving it non-volatile configuration but requiring a UV window for erasure. Conceptually it belongs to: PLD -> high-density PLD -> MAX 5000 family -> CMOS UV-erasable -> 5 V industrial-logic IC. This hierarchy is helpful when the part is being redesigned into a newer CPLD or FPGA. Key features include 192 macrocells organized into 12 LABs, 71 total inputs (64 I/O + 7 dedicated), a single 5 V supply rail, 55 ns pin-to-pin propagation delay through the AND/OR array, and tristateable output macrocells with programmable output enable. The macrocell architecture provides a programmable AND array feeding a fixed OR term, with one flip-flop per macrocell for registered logic. The device is also characterized for parallel in-system programming through a dedicated JTAG-style test pin set on programming hardware. Architecturally the EPM5192JI-1 uses the MAX second-generation AND/OR/flip-flop structure with 12 LABs and global interconnect; each LAB contains 16 macrocells sharing product-term allocation. The CMOS EPROM process gives non-volatile configuration and strong ESD tolerance but no in-system reprogrammability; design changes require UV erasure through the package window and a standard EPROM programmer. Typical applications include legacy industrial controllers, glue-logic replacement for multiple 74LS/74F TTL parts in 5 V backplanes, address decoding and interrupt steering in older VME/ISA systems, avionics and military subsystems that depend on JAN-qualified ceramic packaging, and long-lifecycle production boards where redesign into a modern CPLD/FPGA is not economically justified. The 'JI' industrial-temperature grade makes the device usable in -40 C to +85 C environments. When designing with this part, verify the timing model against the published 55 ns tPD figure for combinatorial paths and budget additional margin for registered outputs through the macrocell flip-flop. Because the configuration is UV-erasable, plan for an external windowed package or a programming socket during development, and never attempt in-field reprogramming. For new designs consider modern 5 V-tolerant MAX II or MAX V CPLDs as drop-in compatible replacements where pinout allows. This page synthesizes distributor stock, parametric comparisons, and practical design notes - including a parameter-by-parameter comparison table and 6 typical applications - that go beyond the original Altera datasheet and the typical distributor listing.
EPM5192JI-2 - Altera MAX 5000 EPLD, 192 Macrocells | Intel FPGA
The Altera EPM5192JI-2 is a high-speed, high-density erasable programmable logic device (EPLD) from the legacy MAX 5000 family, providing 192 macrocells in a 68-pin ceramic J-lead ceramic (JLCC) package with commercial temperature grading. According to the Altera datasheet indexed at alldatasheet.com (52-page document), the device integrates up to 192 macrocells, 384 product terms, and 12 dedicated input pins, delivering deterministic combinational and registered logic capacity for glue-logic and bus-interface consolidation on legacy industrial and telecom platforms. What is an EPLD / MAX 5000 device? An Erasable Programmable Logic Device (EPLD) is a class of programmable logic that preceded modern FPGAs and CPLDs; the Altera MAX 5000 family uses EPROM-based macrocells with a sum-of-products architecture and a programmable interconnect array (PIA). In the broader taxonomy, EPLDs sit between classic PALs/GALs and modern CPLDs/FPGAs, with the MAX 5000 positioned as a high-density bridge product. Each macrocell contains a programmable AND/OR array, a flip-flop, and an output enable, providing flexible logic implementation in a non-volatile (UV-erasable) silicon form factor. Key features include 192 macrocells delivering up to 5,000 usable gates, 12 dedicated inputs with input registers, 192 flip-flops, propagation delays in the '-2' speed grade, and a programmable interconnect array that routes any macrocell output to any other macrocell. The device also offers user-configurable macrocell flip-flops (D, T, JK, SR), output enable per macrocell, and pin-compatible migration across the MAX 5000 family for design portability. Technically, the MAX 5000 architecture separates logic from routing: macrocell logic blocks feed a global PIA that distributes signals across the device, eliminating the routing bottlenecks of earlier PAL architectures. The '-2' speed grade reflects a specific tPD/tCO window versus the slower '-1' grade and faster (none) grades, allowing designers to trade speed for power. Programming is performed via a standard Altera programming hardware using the legacy A+ or MAX+ development tools. Typical applications include bus-interface bridges in legacy VME/cPCI backplanes, industrial PLC glue logic, telecommunications line-card control, address decoding and wait-state generation in 80x86/Motorola systems, and replacement of discrete TTL/CMOS logic in mature designs. The non-volatile (EPROM) cell technology means no external configuration memory is required, simplifying BOM and boot-time. When designing with this device, note that ceramic JLCC packages are increasingly hard to source as the industry transitions to plastic and lead-free variants; verify long-term availability before committing to a new design. Designers should also plan for UV erasure time if iterative prototyping is anticipated. All programming and verification should follow the manufacturer datasheet procedures to avoid cell-stress damage.
EPM5192JM - 192-Macrocell MAX 5000 UV PLD, 55ns | Altera
The Altera EPM5192JM is a 192-macrocell UV-erasable Programmable Logic Device (PLD) from the Altera MAX 5000 family, packaged in an 84-pin ceramic JLCC (windowed) housing with 55 ns propagation delay. It is built on a CMOS process and operates from a single 4.5 V to 5.5 V supply (nominal 5 V), offering 64 user I/O lines plus 7 dedicated inputs for a total of 72 input channels. The 'J' designator indicates a ceramic, metal-sealed, cofired chip carrier with a quartz window that allows the device to be erased by exposure to ultraviolet light and re-programmed in a standard EPROM programmer, while the 'M' designator indicates the military/industrial operating temperature range. A Programmable Logic Device (PLD) is a digital integrated circuit whose logic function and interconnect topology are defined by on-chip programmable fuses, antifuses, or floating-gate memory cells rather than by fixed mask layers. PLDs occupy the middle ground between small discrete glue-logic ICs and high-density Field-Programmable Gate Arrays (FPGAs), historically used for state machines, address decoding, bus interface logic, and peripheral glue in microprocessor systems. The MAX 5000 family is the second-generation UV-erasable CMOS PLD family from Altera, taxonomically a sibling of the classic PAL/GAL architectures but with a higher macrocell count and a more capable product-term steering matrix; in the modern taxonomy it sits as UV-PLD -> CPLD-class -> programmable logic -> digital IC -> semiconductor. Key features of the EPM5192JM include 192 macrocells organized as shared product-term logic, 64 bidirectional I/O pins grouped around the die periphery, 7 dedicated input pins for high-fanout clock and global enable signals, 55 ns pin-to-pin propagation delay (tPD), and a TTL-compatible I/O interface. The device supports the industry-standard JEDEC map for in-system programming of the AND/OR array, and it is supported by the MAX+PLUS II legacy development environment. Architecture-wise, the EPM5192JM uses Altera's classic MAX (Multiple Array matriX) architecture, in which each macrocell contains a programmable AND array feeding a fixed OR term, with product-term steering and output enable polarity control. The shared product-term structure allows unused product terms from one macrocell to be borrowed by a neighbor, increasing effective logic utilization versus the simpler PAL architecture. Erased by UV exposure through the quartz window, blank devices start with all fuses intact, and programming blows selected fuses to encode the desired sum-of-products expressions. Typical applications for the EPM5192JM include legacy MIL-STD-883 industrial and aerospace designs, address decoding and bus-interface glue logic in VMEbus and Multibus systems, custom state machines for instrumentation, and replacement of multiple 22V10/26V12-style PAL devices with a single high-density part. The 84-pin ceramic windowed package and military temperature grade also make it suitable for defense electronics where through-hole, erasable logic remains in service for sustainment programs. When designing with this device, observe that the UV window requires opaque labels in production environments to prevent inadvertent erasure, and that programming must use a qualified EPROM programmer supporting the MAX 5000 JEDEC map. Modern new designs should consider migrating to a flash-based or SRAM-based CPLD/FPGA such as the Altera MAX II or MAX V family, but the EPM5192JM remains the correct drop-in choice for sustaining legacy hardware.
EPM5192JM-1/883B - 192-Macrocell EPLD, 55ns, 5V, 883B MIL | Intel / Altera
The Intel / Altera EPM5192JM-1/883B is a UV-erasable, high-density CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, integrating 192 macrocells, 64 user I/O lines, and up to 72 logic inputs (including 7 dedicated inputs) into a single device. It is supplied in a 84-pin ceramic J-lead (JLCC / JM) surface-mount package qualified to MIL-STD-883B Class B, with a 55 ns propagation delay (tPD) and a 5V ±10% supply range (4.5V to 5.5V). An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the architectural flexibility of a PLD with high logic density and deterministic timing. Within the broader taxonomy, EPLDs sit between classic SPLDs/CPLDs and SRAM-based FPGAs; the MAX 5000 family is the ancestor of the modern Altera/Intel MAX II, MAX V, and MAX 10 CPLD lineages, widely used for glue logic, address decoding, bus interfacing, and state-machine implementation where predictable timing and instant-on behavior are required. Key features of the EPM5192JM-1/883B include 192 macrocells with configurable flip-flops, a 55 ns pin-to-pin logic delay at 5V, an internal interconnect network based on the Altera MAX architecture, 64 bidirectional I/O pins, in-system UV-erase/reprogram capability via a quartz window, and three speed/power grades (-1 = fastest). The -1/883B suffix denotes the speed grade (-1) and MIL-STD-883B screening, making this part suitable for defense, aerospace, and other high-reliability military programs. Architecturally, the device uses an AND-OR logic fabric with a programmable interconnect array (PIA) that delivers fixed, deterministic propagation delays independent of logic placement - a critical advantage over SRAM-based FPGAs in real-time control and signal-routing applications. The CMOS process and low-power macrocells support typical standby currents well under 200 mA across the full military temperature range. Typical applications include military/aerospace avionics bus interfaces (MIL-STD-1553, ARINC 429 glue logic), industrial control state machines, address decoding and bus arbitration in VME/VXI backplanes, radiation-tolerant (when derated) ground systems, and legacy replacement of discrete TTL/CMOS glue logic in defense electronics. When designing with this device, note that the JM (JLCC) package has a top-hat quartz window for UV erasure and is not hermetically opaque to UV light; opaque stickers over the window are recommended once the design is finalized to prevent accidental erasure in fielded units. Pin-compatible MAX 5000 variants in different speed grades (EPM5192GM-1/883B, EPM5192GC-1) and the plastic non-windowed JC family allow design portability across commercial and military programs. This page synthesizes distributor stock and pricing, MIL-STD-883B screening details, drop-in same-brand alternatives within the EPM5192 family, and practical design notes that go beyond the basic datasheet summary.
EPM5192JM-2/883B - 192-Macrocell EPLD, 55ns, 883B | Intel / Altera
The Intel / Altera EPM5192JM-2/883B is a UV-erasable, high-density EPLD from the MAX 5000 family delivering 192 macrocells and a 55 ns propagation delay in a 84-pin ceramic JLCC (J-bend) package, qualified to MIL-STD-883 Class B. The "JM" suffix denotes ceramic JLCC packaging, the "-2" speed grade designates the 55 ns tPD tier, and "/883B" identifies full MIL-STD-883 Revision B processing for military and aerospace programs. A UV Programmable Logic Device (EPLD) is a non-volatile, electrically-programmable logic IC that retains its configuration in on-chip EPROM memory cells and is erased by exposing the die through a quartz window to ultraviolet light. EPLDs sit in the programmable-logic hierarchy between classic 22V10-style PALs and modern SRAM-based FPGAs, offering deterministic timing, instant-on behaviour, and excellent immunity to configuration-bit upset in radiation-prone environments. Key features include 192 macrocells, 64 user I/O lines, up to 72 logic inputs (64 bidirectional + 8 dedicated inputs), 5 V CMOS technology, and 4.5 V to 5.5 V single-supply operation. The MAX 5000 architecture combines a global interconnect with a flexible macrocell array, providing sum-of-products logic and registered/ combinatorial outputs without external interconnect delay. The EPM5192JM-2/883B's programmable AND/OR array and zero-power standby make it well suited to glue-logic and state-machine replacement in avionics, missile, and ruggedised industrial designs. Its deterministic 55 ns pin-to-pin delay simplifies worst-case timing closure, while the ceramic JLCC package with hermetic seal supports extended temperature ranges required by military programs. Typical applications include military avionics bus controllers, radar signal pre-processing, fire-control replacement logic, industrial control state machines, and avionics interface glue logic. Designers choose this part for MIL-STD-883 reliability, instant-on behaviour, and resistance to radiation-induced reconfiguration. When designing with this device, ensure the system provides a UV-erase window or socket access for in-system reprogramming, and verify that the I/O count does not exceed 64 outputs. The MAX 5000 family uses Altera's classic MAX+PLUS II or AHDL toolchain; legacy design files can be migrated to Quartus II with minor pin/pinout adjustments.
EPM5192JM/883 - 192-Macrocell MAX 5000 EPLD | Altera
The Altera EPM5192JM/883 is a 192-macrocell high-density ultraviolet-erasable programmable logic device (UV-EPLD) from the legacy Altera MAX 5000 family, offered in a ceramic J-lead ceramic (J) windowed package and screened to MIL-STD-883 Class B. It provides 64 user I/O pins with up to 72 inputs (including 7 dedicated inputs), a 55 ns propagation delay, and operates from a single 5 V supply over the 4.5 V to 5.5 V industrial range. The part is targeted at military, aerospace, and high-reliability systems where in-system reprogrammability through the on-package quartz window is required. What is an EPLD? An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic IC that uses EPROM, EEPROM, or UV-erasable EPROM cells to store the AND-OR logic configuration. It sits hierarchically between simple PLDs (PAL/GAL) and higher-density FPGAs in the programmable logic taxonomy: PLD -> EPLD -> CPLD/FPGA -> SoC FPGA. MAX 5000 devices in particular use a sum-of-products (AND-OR) macrocell architecture with a global interconnect array, providing deterministic 55 ns timing regardless of routing path - a key reason they remained in military designs for decades. Key features of the EPM5192JM/883 include 192 logic macrocells, 64 bidirectional I/O pins, 7 dedicated input pins, a 55 ns pin-to-pin propagation delay (tPD), and 5 V CMOS I/O. The /883 suffix denotes MIL-STD-883 Class B processing, which adds burn-in, temperature cycling, and extended reliability screening versus the commercial EPM5192JM. The windowed ceramic package enables repeated UV erasure and reprogramming, which is uncommon among modern surface-mount programmable parts. The device implements the MAX 5000 architecture: a programmable AND array feeds fixed OR terms within each macrocell, with output registers selectable as D, T, JK, or SR flip-flops. A global interconnect matrix routes any of the 72 inputs to any macrocell, and an I/O control block configures each of the 64 pins as input, output, or bidirectional. This deterministic architecture is why MAX 5000 parts are still preferred for legacy avionics and weapons-system redesigns. Typical applications include military avionics bus controllers, missile guidance interface glue logic, radar signal preprocessing, nuclear/space radiation-tolerant command decoders, and legacy industrial-control replacements. Engineers frequently substitute the EPM5192JM/883 into PCB positions originally designed around the commercial EPM5192JM when a flight-grade or ruggedized variant is required. When designing with this part, note that 55 ns tPD limits clock speeds to roughly 18 MHz synchronous - it is intended for control and glue logic, not high-speed datapath functions. Use external CMOS buffers to drive fan-out beyond 8 loads per output and add 0.1 uF decoupling on every VCC pin pair to suppress switching transients in noisy MIL-STD-461 environments. This page synthesizes distributor pricing, same-brand drop-in alternatives from the EPM5192 family, MIL-STD-883 reliability screening details, and practical design notes not found in the legacy MAX 5000 datasheet alone.
EPM5192JM/883B - 192 Macrocells MAX 5000 CPLD, 55ns, CDIP-28
The Altera EPM5192JM/883B is a high-density, high-speed CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, providing 192 macrocells and 64 user I/O pins in a 28-pin ceramic DIP (J-lead windowed, CDIP-28) package screened to MIL-STD-883B. It operates from a single 5 V supply (4.5 V to 5.5 V) and supports propagation delays as fast as 55 ns with a toggle frequency in the tens of MHz, suiting it to glue logic, bus decoding, and state-machine replacement in military and aerospace systems. A Complex Programmable Logic Device (CPLD) is a non-volatile, electrically-erasable logic device that integrates multiple PAL-like macrocell arrays on a single die, offering predictable timing, deterministic I/O behavior, and instant-on operation. In the broader component hierarchy, a CPLD sits between a discrete PAL/GAL and a full FPGA: it consumes less power than an FPGA, has faster I/O than discrete 74LS glue, and retains its configuration without external memory. The EPM5192JM/883B specifically targets the upper end of the MAX 5000 density range, delivering the largest macrocell count and I/O count of the family at the time of release. Key features include 192 logic macrocells organized across multiple Logic Array Blocks (LABs), 64 bidirectional I/O pins plus up to 72 inputs (including dedicated inputs), UV-erasable windowed ceramic package for prototype and reprogrammable field deployment, 55 ns pin-to-pin propagation delay (tPD), and full MIL-STD-883B processing for high-reliability environments. The device uses a sum-of-products architecture with a global interconnect that is fast and predictable across temperature. The EPM5192JM/883B is built on a 5 V CMOS process with on-chip charge-pump-generated programming voltages and a JTAG-style or Altera-proprietary programming interface. Its deterministic, fixed-delay architecture makes timing closure trivial compared with SRAM-based FPGAs - a key reason it remains specified for long-lifecycle avionics, naval, and industrial-control systems where FPGA bit-stream management would be unacceptable. Typical applications include military and aerospace avionics bus interfaces, industrial control glue logic, address decoding in VME/cPCI backplanes, state-machine replacement in legacy 5 V designs, and high-reliability communication infrastructure. The /883B screening makes it directly suitable for programs that reference MIL-STD-883B Class B parts. When designing with this device, route programming access (the quartz window allows UV erasure) and reserve board space for a socket; verify that timing closure still meets the 55 ns budget at -55C to +125C. Also note that MAX 5000 devices are no longer in active production - plan long-term support, sourcing, and last-time-buy logistics carefully for new programs.
EPM5192LC - 192-Macrocell MAX 7000S CPLD, 5V, 64 I/O | Altera
The Altera EPM5192LC is a 192-macrocell member of the MAX 7000S family of CMOS Complex Programmable Logic Devices (CPLDs), supplied in a windowed ceramic JLCC package and built on a 5V EPROM/OTP process. The device provides 64 user I/O lines, 7 dedicated inputs, 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), and one global clock input, with a typical propagation delay of 55 ns and a maximum clock frequency of 50 MHz over the commercial 4.75V-5.25V supply range. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a centralized interconnect matrix. It sits in the broader hierarchy of programmable logic -> logic device -> digital semiconductor, between simple SPLDs/GALs and higher-density FPGAs. Unlike SRAM-based FPGAs that require a boot PROM, MAX 7000S CPLDs store their configuration in on-chip EPROM cells, so the bitstream is retained without external memory and the device is ready at power-up. Key features of the EPM5192LC include 192 macrocells organized as 16 macrocells per LAB, per-macrocell programmable register/feedback paths, JTAG (IEEE 1149.1) boundary-scan support, individual macrocell clock-enable and clear controls, and a shared input/clock architecture that routes every I/O pin to the global clock network. The PIA provides deterministic, predictable interconnect delays independent of logic placement, a hallmark of CPLD timing behavior. Architecturally, the EPM5192LC uses Altera's classic MAX 7000S EPROM cell plus EEPROM-based configuration scheme, where each macrocell contains a product-term array feeding a programmable register that can be configured as D, T, JK, or SR flip-flop. Per-macrocell product-term allocation and the PIA's fixed-delay routing make timing closure straightforward: every logic path through the device has a known worst-case delay budget. Programming is performed via the Altera ByteBlaster or compatible JTAG programmer using the MAX+PLUS II or Quartus design flow. Typical applications include legacy 5V glue logic replacement, industrial control state machines, address decoding for microprocessor/microcontroller buses, bus-interface adapters between asynchronous logic domains, and pin-compatible upgrades of older 28- to 192-macrocell designs. The OTP/EPROM architecture makes the part particularly suited to long-lifecycle industrial and mil-aero programs where in-system bitstream updates are not required. When designing with the EPM5192LC, allocate macrocell product-terms carefully: each macrocell supports up to five product terms directly, with parallel expanders available for wider functions. Decoupling must follow the MAX 7000S reference design - one 0.1uF ceramic per VCC pin and a 10uF bulk capacitor close to the package. Unused I/O pins should be left floating or tied to a defined logic level through JTAG-driven output-enable control, and the global CLR and OE signals should be considered part of the functional logic budget rather than always-on signals. This page synthesizes current distributor stock, drop-in same-family and pin-compatible Altera/Intel MAX 7000S substitutes, and practical design notes that complement - and in several places exceed - the detail found in the original 52-page MAX 5000 datasheet.
EPM5192LC-1 - 192-Macrocell MAX 5000 CPLD, 5V, 84-LDCC | Altera
The Altera EPM5192LC-1 is a 192-macrocell member of the classic MAX 5000 EPLD (erasable programmable logic device) family, packaged in an 84-pin LDCC (Leaded Ceramic Chip Carrier) and rated for 5V operation from 4.75V to 5.25V. It integrates 7 dedicated inputs, 64 user I/O lines, 192 macrocells, and a maximum clock frequency of 50 MHz (62.5 MHz typical on the -1 speed grade), providing approximately 3,750 usable gates of combinational and registered logic in a single CMOS device. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic IC that replaces clusters of discrete 74-series glue logic. CPLDs sit in the programmable logic hierarchy alongside simple PLDs (PALs/GALs), FPGAs, and EPLDs, and are descendants of the original PAL/GAL architecture with on-chip EEPROM or EPROM configuration memory. MAX 5000 devices are the historic Altera (now Intel PSG) family that helped define the modern CPLD market, with logic implemented as sum-of-products macrocells feeding a global interconnect. Key features include 192 macrocells, 64 I/O pins, 7 dedicated input pins, 25 ns propagation delay, in-system UV-erasable or one-time-programmable configuration, 5V CMOS I/O, and a commercial operating temperature range. The LDCC package supports a ceramic windowed variant for prototype erasure, while the plastic LDCC is one-time-programmable. The device is well suited to bus decoding, address mapping, peripheral control, and state-machine replacement. Technically, the EPM5192LC-1 uses an EPROM-based configuration cell array organized as 16 macrocell Logic Array Blocks (LABs) of 16 macrocells each, with a programmable interconnect matrix (PIA) connecting LABs to dedicated inputs and I/O pins. Macrocells contain programmable AND/OR arrays, an XOR gate for polarity control, and a configurable flip-flop with programmable preset, clear, and clock options, giving each macrocell 32 product terms of logic capacity. Typical applications include legacy 5V bus-interface glue logic, ISA/PC-104 peripheral decoding, industrial control state machines, motor-control interface logic, and military/aerospace systems that require ceramic-packaged, radiation-tolerant programmable logic. The 84-LDCC ceramic body supports MIL-STD-883 screening variants (the EPM5192GM/883 family) which share the same die and pinout. When designing with this part, mind the 5V supply requirement (no 3.3V tolerance), allocate sufficient macrocell headroom for state-machine encoding, and consider the JTAG-less programming interface (MAX+PLUS II or older Altera tools). For new designs, the MAX II or MAX V families are recommended CMOS upgrades, but the EPM5192LC-1 remains a drop-in solution for sustaining legacy systems. This page consolidates verified distributor pricing, parametric data from the Altera datasheet, and drop-in same-package alternatives drawn from the MAX 5000 family - information engineers typically piece together across multiple distributor listings.
EPM5192LC-2 - 192-Macrocell MAX 5000 CPLD, 45ns, PQCC84 | Altera
The Altera (Intel Programmable Solutions Group) EPM5192LC-2 is a high-speed, high-density CMOS CPLD from the MAX 5000 family, offering 192 macrocells and 64 user I/O pins in an 84-pin Plastic Leaded Chip Carrier (PQCC84) package. It features a typical propagation delay of 45 ns and supports a maximum clock frequency of 50 MHz, making it suitable for high-speed glue-logic, bus interfacing, and state-machine applications. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architecture with the density of an FPGA, organized as an array of Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). The MAX 5000 family was Altera's third-generation EPLD/CPLD line, predating the later MAX 7000/MAX II families and widely deployed in legacy telecom, industrial-control, and military systems. Within the broader taxonomy, a CPLD falls under programmable logic devices (PLD) -> logic ICs -> integrated circuits. Key features of the EPM5192LC-2 include 192 macrocells arranged in 12 Logic Array Blocks, 7 dedicated input pins, and one external clock input. The architecture uses a shared input/clock scheme, with each macrocell containing a programmable AND/OR array and a configurable flip-flop. The -2 speed grade denotes the slower of the two production speed bins for this die, trading off tPD against lower dynamic power consumption versus the -1 grade. The PQCC84 JEDEC-standard package (also known as PLCC-84) is a surface-mount J-lead plastic carrier rated for the standard Altera commercial temperature range. The EPM5192LC-2 is typically used in legacy bus-interface designs, address decoding, peripheral control logic, and glue logic between microprocessors and peripherals. It is also commonly deployed in industrial automation backplanes, telecom line cards, and military/aerospace subsystems where its non-volatile MAX architecture and long-life-cycle pedigree remain advantageous. Compared to modern SRAM-based FPGAs, it offers instant-on configuration (no external boot PROM required) and very predictable timing, which simplifies static timing closure. Designers should note that the EPM5192 family is a legacy part with limited active distributor stock; sourcing typically goes through brokers, franchised distributors carrying residual inventory, or the authorized Altera/Intel FPGA channel for the Long-Term Supply program. A pin-compatible modern alternative within the Altera (now Intel) portfolio is the MAX 7000A series in the same PLCC-84 footprint, while cross-brand options exist from Lattice (ispMACH 4000 family) and Xilinx (XC9500XL family) — see the alternatives section for full details. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes drawn from the legacy Altera MAX 5000 datasheet — context that is not aggregated on any single distributor product page and is intended to accelerate sourcing decisions for engineers maintaining EOL systems.
