EPM5192ALM84-20 - 192-Macrocell MAX 5000 PLD, 84-PLCC | Altera
The Altera EPM5192ALM84-20 is a high-density, UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the MAX 5000 family, integrating 192 macrocells, 64 user I/O pins plus 7 dedicated inputs, and CMOS technology in an 84-terminal PQCC (PLCC) surface-mount package. It supports a maximum clock frequency of 66.7 MHz with a propagation delay of 33 ns through the interconnect, providing deterministic timing suitable for bus-interface glue logic, address decoding, and state-machine replacement. What is a Complex PLD? A Complex Programmable Logic Device (CPLD) is a non-volatile digital logic IC that combines multiple PAL-like macrocell blocks on a single die with a programmable interconnect matrix. Each macrocell contains an AND/OR array feeding a flip-flop, and the entire device is configured by on-chip EPROM or EEPROM cells. CPLDs sit hierarchically between simple SPLDs (PAL/GAL) and FPGAs - they offer lower density than FPGAs but provide deterministic pin-to-pin timing (no routing variability), instant-on configuration, and high drive strength, making them ideal for bus decoding, power-up control, and high-speed control logic. The EPM5192ALM84-20 features an output voltage swing compatible with 5V TTL logic, a programmable security bit for design protection, and a windowless/OTP switch-matrix architecture per the MAX 5000 datasheet. The "ALM84" suffix denotes the 84-pin PLCC package, while "-20" indicates the speed grade (approximately 33 ns propagation delay, tPD). All configuration is stored in EPROM cells - the device is one-time-programmable (OTP) in this package variant since there is no UV window for erasure. Typical applications include TTL/CMOS logic integration, bus-interface controllers, address decoding and chip-select generation, state-machine implementation, and peripheral glue logic for legacy industrial and telecom systems. Because the part is UV-erasable only without a window, it is best suited for production volumes where field reprogramming is not required. When designing with this device, observe the 33 ns worst-case tPD and derate timing for output enable and clock-to-output delays. The PLCC-84 socket allows easy prototype replacement but requires careful ESD handling. Power sequencing is not required - the device powers up with all outputs in a defined state per the MAX 5000 datasheet. This page synthesizes distributor pricing, same-family and cross-brand drop-in alternatives, and practical design notes not aggregated on a single distributor product page, helping engineers rapidly select, source, and integrate the EPM5192ALM84-20 in legacy and new designs.
EPM5192AQC-1 - 192-Macrocell CMOS OTP PLD | Altera MAX 5000
The Altera EPM5192AQC-1 is a 192-macrocell One-Time Programmable (OTP) Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, housed in a 100-pin PQFP (Plastic Quad Flat Pack) package. It features a propagation delay of 40 ns, a maximum clock frequency up to 50 MHz, and operates from a 5 V nominal supply (4.75 V to 5.25 V) across a commercial 0 °C to 70 °C temperature range. The device exposes 64 user I/O lines plus 7 dedicated inputs for a total of 72 inputs and 64 outputs, making it suitable for decoding, interface bridging, and peripheral glue logic. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PLA-style macrocell blocks on a single die with a central interconnect. Unlike FPGAs, CPLDs typically use EEPROM, EPROM, or antifuse configuration cells, so they boot in microseconds with deterministic timing. MAX 5000 series parts in particular use UV-erasable EPROM (or one-time programmable) cells, placing the family at the low-cost, deterministic-timing end of the programmable logic spectrum and serving as predecessors to the later MAX 7000 and MAX II families. Key specifications include 192 macrocells, 64 bidirectional I/O pins, 40 ns pin-to-pin propagation delay (tPD), and a 5 V ±5 % supply tolerance. The PQFP-100 footprint provides ample board real estate but accommodates the high pin count required by 64 I/O plus power, ground, JTAG, and dedicated enable pins. The device uses EPROM-based configuration, supporting both UV erasure (windowed packages) and one-time programmable (OTP) variants for production volumes. The EPM5192AQC-1 uses a classic Altera MAX architecture: sum-of-products logic blocks with a global programmable interconnect, driven by either an internal oscillator or external clock. Each macrocell contains a flip-flop, product-term steering logic, and a programmable output enable, giving designers fine control over registered vs. combinatorial behavior, polarity, and output slew. The 40 ns tPD makes the part appropriate for state machines running up to roughly 25 MHz internally and bus-interface glue running at higher external rates where register-to-register timing dominates. Typical applications include legacy bus interface glue (ISA, PC/104, VME), address decoding for 8-/16-bit microprocessors, peripheral control and signal conditioning, industrial control boards, and replacement of discrete 74LS/74HC logic clusters. Its instant-on OTP behavior suits production designs where programming cost matters more than field reprogrammability. Designers should treat the EPM5192AQC-1 as a legacy part: use the Altera MAX+PLUS II toolchain for design entry, simulation, and programming. Provide a clean 5 V rail with bulk and decoupling capacitors, and avoid driving I/O above 5 V without external clamping, as the device uses 5 V-tolerant CMOS I/O rather than modern fail-safe I/O. This page consolidates verified distributor pricing, parametric data, same-family drop-in alternatives, and design notes not typically surfaced in the original MAX 5000 datasheet, giving procurement engineers and legacy-design maintainers a single reference for the EPM5192AQC-1.
EPM5192AQC-2 - 192-Macrocell OTP CPLD 45ns PQFP-100 | Altera
The Altera (Intel) EPM5192AQC-2 is a 192-macrocell UV-Erasable/One-Time-Programmable (OTP) Complex Programmable Logic Device (CPLD) from the MAX 5000 family, housed in a 100-pin Plastic Quad Flat Pack (R-PQFP-G100) package with 0.635 mm gull-wing lead pitch and a specified 45 ns propagation delay (tPD) on the -2 speed grade. The device integrates 192 macrocells, 64 user I/O lines and 7 dedicated inputs for a total of 72 inputs, implemented in a CMOS process and supported by a non-volatile, anti-fuse/UV-erasable switch matrix that retains the logic configuration after power-down. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits hierarchically between simple SPLDs/GALs and higher-density FPGAs. CPLDs use a predictable AND/OR macrocell fabric with deterministic pin-to-pin timing, making them ideal for glue-logic, bus decoding, address mapping, and power-up state-machine functions where FPGAs would be overkill. The MAX 5000 family, of which the EPM5192AQC-2 is a member, is Altera's classic high-density, OTP/UV-erasable CPLD lineage that established the architecture still used in modern MAX II and MAX V devices. Key features of the EPM5192AQC-2 include 192 macrocells backed by a programmable interconnect array, 64 bi-directional I/O pins with 5V-tolerant interface capability typical of the MAX 5000 generation, dedicated input pins for high-speed clocking and asynchronous control, and JTAG-based in-system programming via the IEEE 1149.1 boundary-scan interface. The OTP (windowless for the AQC package) switch matrix lets the device retain its configuration indefinitely without an external configuration memory. Architecturally, the EPM5192AQC-2 partitions its 192 macrocells into logic array blocks (LABs) with a centralized programmable interconnect, delivering fast, deterministic propagation delay across all paths. The 45 ns tPD on the -2 speed grade is well-suited for interfaces running up to roughly 22 MHz without pipelining, such as legacy peripheral buses and address-decoding logic. The R-PQFP-G100 package exposes the full I/O count and supports surface-mount assembly on standard 0.635 mm-pitch PCB footprints. Typical applications include legacy peripheral bus decoding (ISA, PCI, VME), address mapping and chip-select generation, glue-logic integration between microprocessors and peripherals, industrial control boards that require deterministic timing, and long-life-cycle embedded platforms where OTP non-volatility and 5V tolerance outweigh the need for re-programmability. Compared with SRAM-based FPGAs, the EPM5192AQC-2 powers up instantly in a known state and needs no boot PROM. When designing with this part, allocate adequate PCB area for the PQFP-100 footprint and consider decoupling with 0.1 uF ceramic capacitors adjacent to every supply pin to maintain signal integrity on high-toggle-count nets. Note that AQC suffix denotes a windowless, OTP-only package, so the device cannot be UV-erased after programming. This page synthesizes verified distributor data, parametric drop-in alternatives from the same MAX 5000 family, and practical design notes that go beyond the information typically available on a single manufacturer or distributor listing.
EPM5192AQC100-15 - 192 Macrocell OTP PLD, 25ns, PQFP-100 | Altera
The Altera (now Intel) EPM5192AQC100-15 is a UV-Erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, delivering 192 macrocells with a 25 ns propagation delay in a 100-terminal PQFP (R-PQFP-G100) package. This device features 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), with one external clock input providing synchronous logic support. The architecture supports 72 total inputs, including 7 dedicated inputs, and provides 64 user I/O lines for flexible peripheral and bus interfacing. A Programmable Logic Device (PLD) is a digital integrated circuit whose internal logic and interconnections are user-defined after manufacturing, replacing multiple discrete SSI/MSI gates with a single configurable part. Within the broader semiconductor hierarchy, the EPM5192 sits below microcontrollers and FPGAs but above discrete TTL/CMOS gate arrays - it targets glue-logic and state-machine applications where structured logic is needed but full FPGA density is overkill. The "CPLD" hypernym (Complex PLD) reflects this device's multi-block architecture, distinguishing it from simple PAL/GAL devices. Key features include 192 macrocells of user-configurable logic, 12 LABs with predictable routing through the PIA, a 25 ns pin-to-pin propagation delay (the "-15" speed grade), and OTP (One-Time Programmable) UV-erasable non-volatile configuration memory. The PQFP-100 plastic package provides 64 user I/O pins - a generous ratio that makes the EPM5192 attractive for bus- and peripheral-intensive glue logic. CMOS technology delivers low static power dissipation relative to bipolar predecessors. The EPM5192 uses a classic MAX-style architecture: each macrocell contains a programmable AND/OR array with an output flip-flop, fed by the global PIA. The "-15" speed grade sets worst-case tPD at 25 ns including interconnect delay, which is sufficient for microprocess bus decoding and standard peripheral state machines running in the 20-40 MHz range. Configuration is stored in EPROM cells (UV-erasable windowless variant in the -15 grade per datasheet classification), making the device suitable for prototype runs and low-volume production. Typical applications include microprocessor peripheral decoding (8086/68000 address decoding), peripheral bus arbitration, custom state-machine controllers, industrial machine control logic, and legacy system retrofit where the original PAL/GAL solutions were insufficient. The OTP nature also suits production designs that have stabilized and no longer require in-field reprogramming. When designing with this device, ensure the I/O count does not exceed 64 user I/O pins, and provide proper decoupling (0.1 uF ceramic per VCC pin group). The PQFP-100 package requires careful PCB footprint design; this part is end-of-life on Intel/Altera's active roadmap, so second-source sourcing for new designs is critical. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the original Altera datasheet. All quoted specifications are from the EPM5192 datasheet and distributor listings current as of 2026-09-12.
EPM5192AQC100-20 - 192-Macrocell MAX 5000 EPLD, 33ns | Altera
The Altera EPM5192AQC100-20 is a high-density, UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, integrating 192 macrocells with a maximum clock frequency of 66.7 MHz and a pin-to-pin propagation delay of 33 ns in a 100-lead PQFP package (R-PQFP-G100). A Complex PLD (CPLD) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single CMOS die, providing deterministic combinatorial and registered logic with predictable timing. Within the broader hierarchy, the EPM5192AQC100-20 belongs to: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. The MAX 5000 family sits between classic 22V10-style SPLDs and modern high-density FPGAs, offering deterministic timing, instant-on operation, and high drive strength suitable for bus interface glue logic and address decoding. Key features include 192 macrocells (organized into logic array blocks), 33 ns propagation delay, a 0.65 mm terminal pitch PQFP-100 footprint, and CMOS process technology with UV-erasable or one-time-programmable configuration memory. The device supports 5V operation (typical for the MAX 5000 family) and is housed in a 100-lead plastic quad flat pack (PQFP) rated for the commercial temperature range. Its high-drive I/O cells are well suited for TTL and CMOS bus interfacing. The EPM5192AQC100-20 uses a classic EE-CMOS/UV-CMOS programmable interconnect architecture with a global interconnect matrix, ensuring uniform and predictable timing across all macrocells. Designers rely on this deterministic delay for asynchronous logic decoding where race conditions cannot be tolerated, and the 33 ns worst-case propagation delay is comparable to bipolar PAL devices while consuming far less power. Typical applications include address decoding for microprocessor and DSP systems, bus interfacing and arbitration logic, state-machine controllers, and legacy industrial glue-logic replacement. The 192-macrocell capacity is well matched to wide-word decoders (e.g., 24-bit or 32-bit address decoding) and multi-channel peripheral control. When designing with this device, treat the PQFP-100 as a through-hole or socketed assembly footprint: the 0.65 mm pitch demands careful PCB layout and the package is generally not hand-solderable. Because the part is in the MAX 5000 family (an older technology node), confirm long-term availability and consider newer MAX II/MAX V CPLDs for new designs unless pin-compatibility to the legacy footprint is mandatory. This page synthesizes distributor pricing, drop-in same-family variants, and practical design notes for legacy support use cases not covered in the original 1990s-vintage datasheet.
EPM5192AQI100-15 - 192-Macrocell MAX 5000 PLD, 15ns, PQFP-100
The Altera EPM5192AQI100-15 is a high-density, 25ns (15ns pin-to-pin at commercial grade) CMOS Erasable Programmable Logic Device (EPLD) from the MAX® 5000 family, housed in a 100-pin Plastic Quad Flat Pack (PQFP-100 / R-PQFP-G100) industrial-grade package. The device integrates 192 macrocells organized as 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), with 64 programmable I/O lines, 7 dedicated inputs, and a guaranteed maximum clock frequency of 83.3 MHz. What is a MAX 5000 EPLD? An EPLD (Erasable Programmable Logic Device) is a non-volatile, one-time-programmable (OTP) variant of a PLD that combines multiple PAL-like macrocells with a global interconnect matrix, occupying the mid-density position between classic PAL/GAL devices and modern FPGAs. The MAX 5000 family specifically targets glue-logic integration, bus decoding, state-machine control, and peripheral interfacing where deterministic 15 ns timing and zero in-system reprogrammability are acceptable. Key features of the EPM5192AQI100-15 include 192 macrocells (384 product terms equivalent), 64 user I/O with 5V-tolerant interfaces, 7 dedicated input pins (total 72 logical inputs to the PIA), a 25 ns worst-case pin-to-pin propagation delay for the -15 speed grade, a 15 ns typical tpd, and 100% TTL-compatible I/O. The industrial (-15 I/Q) temperature range covers -40C to +85C, making this part suitable for factory-floor and outdoor-cabinet designs. Architecturally, the device uses a Product Term Sharing Architecture (PTSA) where each macrocell can borrow unused product terms from neighboring macrocells, improving utilization over earlier PAL/GAL architectures. The PIA routes any LAB to any other LAB with a uniform predictable delay, simplifying timing closure. Programming is performed via a JTAG-style or legacy Altera programming algorithm using the MasterBlaster, ByteBlasterMV, or universal USB-Blaster hardware. Typical applications include peripheral bus decoders (PCI/ISA glue logic), high-speed state machines, address decoding for 8/16/32-bit microprocessors, replacement of discrete 74LS/74F TTL logic, motor control sequencers, and industrial automation controllers. The 15 ns tpd comfortably drives 50 MHz synchronous logic with one clock of margin. When designing with the EPM5192AQI100-15, remember that the 'I' suffix denotes industrial temperature grade and the '15' denotes the speed grade in nanoseconds. Ensure all unused I/O pins are left floating or tied to a defined logic level through the Quartus/MAX+PLUS II software configuration to minimize quiescent current and AC noise injection.

The Altera EPM5192AQI100-20 is a member of the classic MAX 5000 Erasable Programmable Logic Device (EPLD) family, providing 192 macrocells in a 100-pin PQFP (Plastic Quad Flat Pack) package. The "-20" speed grade denotes a 20 ns propagation delay through the Logic Array Blocks (LABs) and Programmable Interconnect Array (PIA). The part is implemented in CMOS technology and is rated for industrial temperature operation per the "I" suffix, making it suitable for non-automotive commercial and industrial designs. A Programmable Logic Device (PLD) is a digital integrated circuit whose logic function is defined by the user after manufacture, falling within the broader hierarchy of programmable logic -> logic IC -> integrated circuit. EPLDs such as the EPM5192 use erasable CMOS (UV-erasable EPROM) technology to store the user's logic, and historically served as glue-logic replacements for multiple SSI/MSI 74-series parts. Within Altera's portfolio, the MAX 5000 family occupies the high-density tier above MAX 7000's predecessors and was widely adopted for bus interfacing, state machines, and peripheral controllers in the 1990s. Key features of the EPM5192AQI100-20 include 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), 7 dedicated input pins, and 64 bidirectional I/O lines, all packaged in the JESD-30 R-PQFP-G100 outline (PQFP-100). The device provides predictable, deterministic timing and is supported by the Altera classic MAX+PLUS II design environment. The 100-pin PQFP format offers generous I/O for a part of this era, and the CMOS process delivers low static power compared to older bipolar PALs. Typical applications for the EPM5192 family include legacy bus-interface bridges, address decoding, glue logic between microprocessors and peripherals, and custom peripheral controllers in industrial automation equipment. The 192 macrocells deliver substantial capacity for designs that would otherwise consume a dozen or more discrete logic packages, reducing board area and improving reliability. The PQFP-100 footprint remains compatible with many second-source sockets used in long-lifecycle industrial products. When designing with this part, verify that target toolchains (MAX+PLUS II or compatible third-party compilers) are still available, and that the 5 V tolerant I/O and supply are compatible with downstream logic. Existing designs ported to newer Altera/Intel MAX families (MAX II, MAX V, MAX 10) typically migrate by re-synthesizing the original source, not by socket replacement, due to differing architectures and pinouts.
EPM5192AQM100-15 - 25ns MAX 5000 EPLD, 64 I/O | Altera
The Altera EPM5192AQM100-15 is a 25ns CMOS Erasable Programmable Logic Device (EPLD) from the legacy MAX 5000 family, housed in a 100-pin PQFP (R-PQFP-G100) package. The device contains 12 Programmable Array Logic (PAL) style Logic Array Blocks (LABs) interconnected by a Product Term Sharing Architecture (PIA), with 64 user I/O lines, 7 dedicated inputs, and a total of 72 inputs available for design entry. It is part of the high-density, high-speed MAX 5000 series historically used for glue-logic integration and bus-interface state machines in industrial and telecom systems. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines AND/OR logic arrays with user-programmable interconnect. EPLDs sit in the programmable logic hierarchy between simple PLDs (PAL/GAL) and early CPLDs/FPGAs - they offer deterministic timing, UV-erasable programmability, and integration of multiple PAL macros on a single die. Like all members of the MAX 5000 family, the EPM5192AQM100-15 uses the classic Altera AHDL or schematic-based design flow and stores configuration in EPROM cells, giving engineers stable, reprogrammable logic for long-lifecycle designs. Key features include 25ns pin-to-pin propagation delay (tPD), EPROM-based non-volatile configuration, 12 LABs with shared product-term distribution, and 64 bidirectional I/O pins arranged around the PQFP-100 perimeter. The "-15" speed grade corresponds to the 15ns internal macrocell delay used in the original MAX 5000 datasheet. Per the Altera MAX 5000 datasheet, the device operates from a single 5V supply and is offered in windowed ceramic (military) and plastic (commercial) packages. Architecturally, each LAB contains multiple macrocells with shared product terms, and the PIA routes signals between LABs. This product-term-sharing approach maximises logic utilisation compared with simple PALs. The 25ns tPD makes the device suitable for decoder, encoder, counter, state-machine, and bus-arbitration functions at frequencies up to roughly 30-40 MHz. Typical applications include industrial control glue logic, address decoding for microprocessor/microcontroller systems, peripheral-interface glue (e.g., 8255/6821 replacement logic), bus-architecture adapters (ISA/PCI glue), and legacy telecom interface cards. The PQFP-100 footprint is widely accepted in through-hole and socketed designs where field upgrades via UV erasure are valued. When designing with this part, remember that the "M" suffix in EPM5192AQM100-15 indicates the PQFP-100 package and the "-15" indicates the 15ns speed grade. The device is UV-erasable; ceramic-windowed packages are required for reprogramming. Pin-compatible MAX 5000A family devices may be considered for new designs where available.

It provides 64 user I/O lines plus 7 dedicated inputs, a maximum external clock frequency of 66.7 MHz, and a pin-to-pin propagation delay of 33 ns, all housed in a 100-lead Metric Plastic Quad Flat Pack (PQFP) per JESD-30 code R-PQFP-G100. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that combines multiple PAL-like macrocell blocks with a central interconnect matrix, providing glue-logic integration, bus decoding, state-machine implementation, and address mapping in a single chip. CPLDs sit alongside FPGAs in the programmable logic hierarchy but offer deterministic timing, instant-on configuration from on-chip EPROM/EEPROM, and simpler tool flows. The MAX 5000 series is an early-1990s EPLD lineage later folded into Intel's (formerly Altera's) classic device portfolio. Key features include 12 LABs each containing 16 macrocells, 64 I/O pins with individually programmable direction, a JTAG/IEEE 1149.1 boundary-scan test interface, and an external clock input pin for synchronous design entry. The CMOS EPROM-based architecture stores the configuration permanently, eliminating the need for a separate boot PROM. Operating voltage and temperature grades are designated by the part suffix, with 'M' indicating the commercial plastic PQFP package in this part number. Architecturally, the PIA routes signals between LABs and I/O pins with predictable, fixed delays independent of routing density, which is a hallmark advantage of CPLDs over FPGAs in glue-logic applications. This deterministic timing simplifies static timing analysis at 33 ns tPD and 66.7 MHz fMAX. The device is supported by classic Altera MAX+PLUS II and Quartus design software flows, accepting hardware-description-language and schematic entry. Typical applications include bus-interface bridging (e.g., 8-bit to 16-bit decoding), address decoding and chip-select generation for microprocessor systems, peripheral glue logic in industrial controllers, and replacement of multiple discrete 74-series TTL/CMOS logic gates. Its 33 ns propagation delay is well-matched to legacy ISA bus and 25-40 MHz microcontroller peripheral timing budgets. When designing with this device, observe the recommended 100-pin PQFP PCB land pattern, ensure proper decoupling on each VCC/GND pair, and use the JTAG chain for in-system programming and boundary-scan test. Configuration is one-time EPROM; UV-erasure is not applicable in this windowed-less package, so design changes require a new part.

The device is organized as 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), providing flexible logic integration with 7 dedicated inputs and one external clock input. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a programmable logic device that sits in the hierarchy between simple PAL/GAL devices and high-density FPGAs. CPLDs offer non-volatile configuration, deterministic timing, instant-on behavior, and predictable pin-to-pin delays, making them ideal for glue logic, bus interfacing, and state-machine replacement in industrial and telecom designs. Within Altera's portfolio, MAX 5000 CPLDs occupy the classic high-density tier, with the EPM5192C-2 serving as the 192-macrocell density point. Key features include 192 macrocells, 64 I/O lines, a 45 ns propagation delay through the PIA, 50 MHz maximum operating frequency, and a CMOS process for low static power. The device supports in-system programmability through the Altera MAX+ programming environment with industry-standard JTAG interface support. The architecture provides deterministic timing that simplifies timing closure for control-logic and bus-interface functions. From an architectural standpoint, the EPM5192C-2 uses an EEPROM-based configuration cell that retains programming without external memory, providing instant-on operation at power-up. The 12 LABs each contain 16 macrocells, with the PIA providing uniform routing between blocks to keep interconnect delays predictable. This makes the part well suited for synchronous state machines and address decoding tasks. Typical applications include bus decoding and address mapping in embedded systems, glue logic between microprocessors and peripherals, industrial control and instrumentation, telecommunications line-card interface logic, and replacement of discrete TTL/CMOS logic on legacy boards. When designing with this part, verify timing budgets against the 45 ns PIA delay under worst-case commercial conditions and confirm the JTAG chain order when multiple programmable devices share a single boundary-scan port. Older Altera MAX 5000 software (MAX+PLUS II) is required for legacy device support.

EPM5192GC-1 - 192-Macrocell UV CPLD 5V 62.5MHz | Altera MAX 5000
The Altera (now Intel Programmable Solutions Group) EPM5192GC-1 is a UV-erasable/OTP CMOS Complex Programmable Logic Device (CPLD) from the classic MAX 5000 family, featuring 192 macrocells, 3,750 usable gates, and a maximum propagation delay of 40 ns at 62.5 MHz fmax, housed in a 100-pin Ceramic PGA (Pin Grid Array, package code GC) chassis. The device supports 7 dedicated inputs and 64 user I/O lines organized as 12 Logic Array Blocks (LABs) interconnected by a Peripheral Interconnect Array (PIA) that provides deterministic, fixed propagation delays. A Complex Programmable Logic Device (CPLD) is a non-volatile, flash/EPROM/OTP-based programmable logic IC that combines the architectural simplicity of PAL/GAL devices with macrocell granularity suited for glue-logic, bus decoding, and state-machine consolidation. The MAX 5000 family sits at the bottom of the CPLD hierarchy (CPLD -> Programmable Logic Device -> Logic IC -> Semiconductor) and historically served as the predecessor to MAX 7000/MAX II families in 5V system designs. Compared with FPGAs, CPLDs offer predictable timing, lower power, instant-on behaviour, and superior fit for decoder/register/reset-controller roles. Key features include 4.75 V to 5.25 V single-supply operation, 12 LABs each containing 16 macrocells, a global PIA routing fabric with continuous interconnect, programmable macrocell flip-flops, and a JTAG-friendly erasable/OTP configuration cell. The 'GC' package is a ceramic Pin Grid Array that supports military/aerospace temperature grades and is well-suited for high-reliability through-hole assembly. The architecture uses EEPROM/UV-CMOS configuration cells that retain logic when power is removed, with propagation delays characterized across commercial, industrial, and military temperature ranges. The single 5 V rail simplifies legacy system migration where 3.3 V tolerance is not required. Typical applications include military and aerospace control logic, industrial 5 V bus-interface glue logic, address decoding in legacy 80C86/80C51 systems, parallel-port expanders, and state-machine replacement of discrete TTL. The wide operating voltage and ruggedized PGA package suit long-lifecycle industrial designs and fielded avionics where modern 3.3 V-only CPLDs are unacceptable. When designing with this part, note that it is an older UV-erasable device: reprogramming requires windowed packages or OTP one-time programming. Modern MAX II/MAX V or Lattice ispMACH equivalents may provide lower power and in-system programmability, but the EPM5192GC-1 remains a reference for 5V long-lifecycle designs.
EPM5192GC-2 - 192-Macrocell MAX 5000 CPLD PGA | Intel / Altera
The Intel / Altera EPM5192GC-2 is a high-density, high-speed CMOS erasable programmable logic device (EPLD) from the MAX 5000 family, providing 192 macrocells in a pin-grid-array ceramic package. It operates at 5 V and is rated for the -2 speed grade, which is one of the faster commercial grades within the MAX 5000 series. The device integrates classical AND-OR logic arrays with a global interconnect network, enabling fast, deterministic state-machine and glue-logic implementations in legacy systems. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-style macrocells on a single die and retains its configuration without external memory. Within the broader taxonomy, the EPM5192GC-2 sits in the hierarchy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. MAX 5000 parts are the second-generation MAX architecture, succeeding the classic MAX 7000-style AND-OR planes and preceding the later MAX 9000 family, and were widely used for address decoding, bus arbitration, and peripheral control in 5 V industrial designs. Key features of the EPM5192GC-2 include 192 macrocells (organized as 16 logic array blocks of 16 macrocells each), up to 36 usable I/O pins (the exact number depends on the PGA pinout), 12 ns typical propagation delay at the -2 grade, and 100 MHz+ counter operation. The part supports user-programmable I/O pull-ups, configurable output slew rates, and JTAG-style boundary-scan for board test. Programming is performed using the Altera MAX+PLUS II toolchain through a hardware programmer; the device retains its pattern via on-chip UV-erasable EPROM cells. Architecturally, the EPM5192GC-2 uses a sum-of-products AND array feeding an OR/feedback network with per-macrocell flip-flops, providing deterministic pin-to-pin timing that does not depend on the programmed pattern. This deterministic timing makes the device ideal for asynchronous logic, address decoding, and state-machine implementations where FPGA routing variability would be unacceptable. Typical applications include 5 V glue logic in VME/ISA bus controllers, address decoding in legacy microprocessor systems, peripheral control in industrial PLCs, and replacement of discrete TTL/MSI logic. The ceramic PGA package and -2 speed grade also make it attractive for legacy aerospace and military systems where PGA through-hole packages are preferred for thermal and reliability reasons. When designing with the EPM5192GC-2, ensure the device is socketed or installed with appropriate PGA tooling because the package is not hand-solderable. Verify the 5 V VCC tolerance against the host system's rail and respect the recommended decoupling scheme: at least one 0.1 uF ceramic per VCC pin cluster plus a bulk tantalum/electrolytic cap on the board.

The Altera EPM5192GC1 is a UV-erasable, one-time-programmable (OTP) Complex Programmable Logic Device (CPLD) from the MAX 5000 family, providing 3,750 usable gates and 192 macrocells in a single high-density package. It operates from a 5V supply and supports pin-to-pin toggle frequencies up to 62.5 MHz, making it well suited for glue-logic, bus-interface, and state-machine replacement tasks in legacy industrial and telecom systems. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip with a programmable interconnect network. Within the broader programmable logic hierarchy, a CPLD sits below an FPGA (Field-Programmable Gate Array) and above simple SPLDs, offering deterministic pin-to-pin timing (typically 10-15 ns propagation delay), instant-on operation from on-chip EEPROM/EPROM, and high fan-in/fan-out capability. The MAX 5000 family is Altera's classic second-generation CPLD line, sharing architectural heritage with the earlier MAX 7000 series. Key features of the EPM5192GC1 include 192 macrocells organized into logic array blocks (LABs), 100% connectivity with predictable interconnect delays, programmable power-saving mode per macrocell, and a 5V VCC supply rail that simplifies integration with TTL/CMOS legacy designs. The device is offered in a ceramic PGA (Pin Grid Array) package, denoted by the GC1 suffix, which supports high-reliability military and aerospace screening. Architecturally, the EPM5192GC1 employs an EPROM-based configuration cell, allowing the device to be programmed once and retain logic in the absence of power. Each macrocell contains a programmable AND/OR array followed by a configurable flip-flop with selectable clear, preset, and clock options. The interconnect matrix is continuous across the chip, eliminating the need for manual routing iteration. Typical applications include legacy bus-interface bridges (ISA, VME, and PCI-5V), address decoding and chip-select generation in 5V microcontroller systems, industrial control boards requiring instant-on logic, telecom backplane glue logic, and aerospace/military systems that demand PGA hermetic packaging. The ceramic GC1 package is specifically designed for environments requiring extended temperature range and mechanical robustness. When designing with this part, note that the EPROM cell cannot be re-programmed in-circuit; design changes require a UV eraser (windowed package) or device replacement. Designers should also verify timing closure using the Altera MAX+PLUS II toolchain, which remains the legacy development environment for this family.

EPM5192GC84-1 - 192-Macrocell CMOS UV PLD, 84-pin PGA | Altera
The Altera EPM5192GC84-1 is a UV-erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, integrating 192 macrocells in an 84-pin PGA (Pin Grid Array) package. It features a maximum propagation delay of 40 ns (the "-1" speed grade) and supports a maximum clock frequency of 50 MHz, making it suitable for high-density glue-logic, bus-interface, and state-machine designs of the early-to-mid 1990s era. The device operates from a 4.75 V to 5.25 V single 5 V supply with CMOS technology. What is a UV-erasable Complex PLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on semiconductor that implements combinatorial and sequential logic via user-programmable AND/OR arrays. The MAX 5000 family preceded modern SRAM-based FPGAs and was typically programmed once (OTP, one-time programmable) or, in this "GC" UV variant, erased via exposure to ultraviolet light through a quartz window on the package and re-programmed. Within the broader taxonomy, the EPM5192 sits as: PLD -> CPLD -> UV-erasable CPLD -> MAX 5000 series -> high-density glue-logic IC. Key features include 192 macrocells, 7 dedicated inputs, 64 user I/O pins (totalling 72 inputs / 64 outputs from the part's perspective), and shared input/clock plus shared product-term architecture that allows flexible macrocell configuration. The device supports in-system functional verification through the Altera MAX+plus II design flow, JTAG-based testing, and traditional UV erasure. Its non-volatile, instant-on behavior avoids the SRAM configuration latency that plagues SRAM-based FPGAs, an advantage in deterministic boot applications. The EPM5192GC84-1 uses a CMOS EPROM-cell-based logic array fabricated on an EPI-layer process typical of Altera's MAX 5000 generation. Its 40 ns propagation delay places it in the medium-speed tier suitable for address decoding, peripheral control, bus arbitration, and state-machine replacement of 74LS/74F discrete logic. With 192 macrocells, it can replace dozens of PAL/GAL devices, reducing board area and improving reliability. Typical applications include industrial control glue-logic, telecommunications backplane address decoding, disk-controller state machines, AT/ISA-bus interface controllers, and legacy computing peripherals. The "-1" speed grade makes it the fastest variant in the EPM5192 family, fitting designs where 40 ns tPD is the critical timing parameter. When designing with this device, engineers should verify UV-erase window handling (a quartz lid is required for re-programmability) and ensure the PGA-84 socket is keyed correctly. Modern migration paths include pin-compatible MAX 7000-series and MAX II CPLDs, but require PCB rework due to package differences. For new designs, consider MAX II or MAX V devices from Intel (formerly Altera). This page synthesizes distributor availability, parametric cross-references, and historical application context not aggregated in any single manufacturer datasheet — useful for engineers maintaining or replicating legacy systems that still depend on MAX 5000 silicon.
EPM5192GI - 192-Macrocell UV CPLD MAX 5000 | Altera
The Altera EPM5192GI is a 192-macrocell UV-erasable/OTP CMOS Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, packaged in an 84-pin PGA ceramic form factor with industrial temperature grading. It is specified with a 55 ns pin-to-pin propagation delay (tPD) and a maximum clock frequency of 33.3 MHz, with 64 user I/O lines organized around 7 dedicated inputs and 72 total inputs. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that sits in the hierarchy between simple SPLDs/GALs and FPGAs. It consists of multiple macrocell arrays (typically grouped into Logic Array Blocks) with a centralized, predictable interconnect. Compared to FPGAs, CPLDs offer lower density but faster, deterministic timing, lower power, instant-on non-volatile configuration, and simpler ISP/UV/OTP programming, making them ideal for glue-logic, bus decoding, state-machine control, and I/O expansion rather than parallel data-path processing. The EPM5192GI is fabricated on a CMOS EPROM process with a 5 V single supply (4.5 V to 5.5 V) and operates over the industrial temperature range. Its 192 macrocells, organized into 16 Logic Array Blocks of 12 macrocells each, deliver the high logic density of the MAX 5000 series. The 55 ns tPD is consistent with the slowest speed grade of the family and suits control-logic, address decoding, and peripheral-interface applications where timing closure is straightforward. The 84-pin PGA (Pin Grid Array) ceramic package with an integrated quartz window enables UV erasure and re-programming, while the same silicon is offered in OTP variants (-1, -2) without the window. Designers can re-program the device by exposing the die through the window to UV light and reloading the JEDEC fuse map. Typical applications include industrial control glue-logic, address decoding and wait-state generation for legacy microprocessors, peripheral bus interfacing (ISA, STD, VME), state-machine controllers, and replacement of discrete 74LS/74F logic in long-lifecycle military and aerospace programs. When designing with this device, use Altera's MAX+PLUS II baseline development environment for schematic capture, VHDL/Verilog HDL synthesis, simulation, and JEDEC programming file generation. Confirm that timing constraints can be met at 55 ns with margin; otherwise consider EPM5192GM (faster speed grade) if available in the same PGA package. This page consolidates distributor pricing, verified specifications, drop-in alternative candidates from the same MAX 5000 family, and practical design notes not duplicated from the manufacturer datasheet, giving the engineer a single source for sourcing and second-sourcing decisions.
EPM5192GI-1 - 192-Macrocell UV PLD MAX 5000 PGA-84 | Altera
The Altera EPM5192GI-1 is a UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, delivering 192 macrocells with 64 user I/O lines and 7 dedicated inputs in an 84-pin PGA package. It features a propagation delay of 25 ns and a maximum clock frequency of 62.5 MHz, organized around a PAL-type architecture suitable for high-density glue-logic integration. A Complex Programmable Logic Device (CPLD) is a non-volatile, EEPROM- or EPROM-based logic device that implements combinational and sequential digital functions using a fabric of AND/OR arrays, macrocells, and a programmable interconnect. CPLDs sit in the programmable logic hierarchy between simple SPLDs (PAL/GAL) and FPGAs: they offer deterministic timing, instant-on behaviour, and high fan-in per macrocell, making them ideal for bus decoding, state-machine control, address mapping, and board-level glue logic where FPGAs would be overkill. Within the broader Altera/Intel MAX taxonomy (MAX 5000 -> MAX 7000 -> MAX II -> MAX V -> MAX 10), the MAX 5000 series represents the earliest UV-erasable generation. Key features of the EPM5192GI-1 include 192 macrocells, 64 bi-directional I/O pins, 7 dedicated input pins, 25 ns tPD combinational delay, 62.5 MHz fMAX, and a UV-erasable configuration memory (windowed ceramic PGA package) that supports unlimited reprogramming cycles in development. Industrial operating temperature range (-40C to +85C), 5.0 V VCC tolerance, and CMOS process technology round out the electrical envelope. The EPM5192GI-1 architecture follows the classic MAX 5000 LAB (Logic Array Block) structure: each LAB contains 16 macrocells, each macrocell embeds a programmable AND/OR array, a flip-flop, and an I/O control block. Twelve LABs (192 macrocells total) share a Programmable Interconnect Array (PIA) that routes any LAB output to any other LAB input, providing 100% connectivity. The 7 dedicated inputs feed the global control network for clock, clear, and output enable distribution. Typical applications include legacy industrial control boards, MIL-STD-1553 bus interface glue logic, vintage computer expansion bus decoding (VME, ISA), telecommunications backplane address decoding, and avionics subsystems that require radiation-tolerant, instant-on, non-volatile logic. The UV-erasable windowed package also makes the part valuable for prototype and low-volume production runs where field re-programmability is desired. When designing with the EPM5192GI-1, note that UV erasure requires a windowed ceramic package and a 30-45 minute UV lamp exposure - this is not suitable for in-system reprogramming. Designers migrating to modern designs should consider MAX II, MAX V, or MAX 10 CPLDs (instant-on, non-volatile, in-system programmable) unless legacy drop-in compatibility or MIL-spec traceability is required.

The Intel / Altera EPM5192GI-2 is a CMOS UV-erasable (one-time-programmable) Programmable Logic Device (PLD) from the legacy Altera MAX 5000 family, offering 192 macrocells, 64 I/O pins, and a propagation delay of 30 ns in an 84-pin PGA (Pin Grid Array) industrial-temperature package. It is pin-compatible with the broader EPM5192 die family and supports logic densities typical of glue-logic, bus-interface, and state-machine replacement tasks. Programmable Logic Devices (PLDs) are pre-fabricated semiconductor ICs whose internal logic structure is configured by the end user through programming. The MAX 5000 architecture is built from an array of logic blocks (macrocells) interconnected by a programmable AND/OR fabric; this places it in the broader hierarchy of programmable logic that includes SPLDs, CPLDs, and FPGAs. Within that taxonomy, the MAX 5000 sits as an early high-density SPLD/early-CPLD, sitting below modern CPLDs such as MAX II/MAX V in density and feature count. Key features of the EPM5192GI-2 include 192 macrocells, 64 user I/O lines, 7 dedicated inputs, and 72 total inputs, with a maximum clock frequency of 33.3 MHz and a propagation delay (tPD) of 30 ns. The part operates from a single 5 V supply (4.5 V to 5.5 V), supports a UV-erase window for prototype re-programmability, and is graded for the industrial temperature range. The 84-pin PGA package provides robust through-hole pin-grid solderability suited to industrial backplane designs. In terms of architecture, the EPM5192GI-2 integrates Altera's classic EEPROM-based logic element with a global interconnect, allowing combinational and registered logic to be merged into a single device. This combination is useful for replacing dozens of 74-series TTL parts with one PLD while preserving through-hole manufacturing flows common in aerospace, defense, and long-lifecycle industrial platforms. Typical applications include bus-interface bridging (e.g., ISA-to-local bus glue logic), address decoding and wait-state generation, state-machine controllers, industrial control logic, and legacy avionic/defense subsystems that still require PGA-packaged UV-erasable PLDs. The industrial temperature grade also makes the device suitable for factory-floor controllers and outdoor instrumentation enclosures. When designing with this part, note that PGA packages require through-hole PCB mounting and a UV-erase socket for prototype re-programming. Because the EPM5192GI-2 is a legacy Altera part now supported by Intel, lead time and minimum-order quantities should be confirmed with the supplier before committing the design to volume production. This page synthesizes distributor pricing, drop-in same-family alternatives, application guidance, and design notes that go beyond what the manufacturer datasheet alone provides, helping engineers source and qualify the EPM5192GI-2 efficiently.

The device is built on Altera's classic EPROM-based architecture that allows full bit-level reprogrammability after UV erasure, while also supporting one-time programmable (OTP) operation for volume production. A Complex Programmable Logic Device (CPLD) is a non-volatile, deterministic-latency programmable logic IC that integrates multiple PAL/GAL-like logic array blocks (LABs) with a central programmable interconnect matrix (PIA). Within the broader taxonomy, the EPM5192GI84 sits as CPLD -> programmable logic -> logic IC -> integrated circuit. MAX 5000 CPLDs were widely adopted as 'glue logic' replacements for 74-series TTL and PAL/GAL devices, providing high pin-count integration with propagation delays measured in nanoseconds and zero-power standby modes. Key features of the EPM5192GI84 include 192 macrocells distributed across multiple logic array blocks, 100% factory-tested logic, programmable interconnect architecture with deterministic timing, and JTAG/ISP-friendly boundary-scan testability (subject to variant). Each macrocell provides a programmable flip-flop with configurable D, T, JK, or SR modes and selectable clock options, while the device supports high-speed combinatorial and registered logic implementations. From an architectural standpoint, the MAX 5000 family uses Altera's second-generation architecture with enhanced interconnect and higher macrocell density. The UV-erasable window on ceramic packages allows bench-top erasure for prototyping, while plastic OTP variants target production. Programming is performed via Altera's MAX+PLUS II or older A+PLUS software using industry-standard JEDEC map files. Typical applications include industrial control logic, glue-logic replacement for 74-series TTL, address decoding in microprocessor systems, bus interfacing, state-machine controllers, and legacy telecom infrastructure. The EPM5192GI84 is commonly specified in systems that require high logic density with deterministic, nanosecond-class propagation delays and non-volatile configuration. Designers should note that MAX 5000 devices require a 5 V supply and have TTL-compatible I/O, making them incompatible with modern 3.3 V or lower-voltage logic without level translation. Programming hardware is increasingly difficult to source as the family is well past its mainstream lifecycle. This page synthesizes legacy distributor inventory, EOL-equivalent guidance, and design notes not found in a single datasheet resource, helping engineers verify availability, plan board-level drop-in replacements, and understand how the EPM5192GI84 compares to other MAX 5000 package and speed grades.

It combines innovative MAX architecture with an advanced CMOS process to provide 3,750 usable gates, pin-to-pin delays as fast as 15 ns, and counter frequencies up to 76.9 MHz in the fastest speed grade. The 'GM' suffix denotes the ceramic-windowed (UV-erasable) PGA-84 package, which is suitable for prototype development and design iteration. The MAX 5000 family occupies the programmable-logic tier of the classical PLD taxonomy (PLD -> SPLD/CPLD -> UV-erasable/Electrically erasable CMOS PLD -> MAX 5000 series). As a UV-erasable SPLD, the EPM5192GM was designed in an era when designers needed non-volatile, reprogrammable logic with predictable timing and deterministic pin-to-pin delays — before CPLDs and FPGAs dominated general-purpose logic integration. The 192 logic cells (macro cells) and AND-OR-I/O architecture give the part a strong logic-to-pin ratio, making it well suited for state machines, address decoding, glue logic and bus interfacing. Key features include 192 macro cells, a tPD as low as 15 ns, an fCNT counter frequency up to 76.9 MHz, and a maximum of 84 user I/O pins (depending on pinout configuration). The CPGA-84 windowed ceramic package provides rugged mechanical stability and UV erasure through the top window. The device operates from a single 5 V supply and is fabricated on a 0.8 µm CMOS process that is well-characterised for industrial and military environments. According to the Altera MAX 5000 datasheet family document, all MAX 5000 devices share a common JEDEC-standard JTAG-compatible programming interface and pinout topology. Typical applications of the EPM5192GM include legacy industrial control systems, MIL-STD-883 aerospace and defense designs, prototype PLD-based glue logic, bus-architecture address decoding (e.g., DEC, Intel, Motorola microprocessor glue), TTL/CMOS logic replacement and high-reliability long-lifecycle programs. The UV-erasable windowed package also makes it popular for engineering development where iterative erasure and re-programming are required. When designing with the EPM5192GM, ensure the design uses 5 V tolerant I/O only — the device does not support 3.3 V mixed-voltage operation. Place 0.1 µF decoupling capacitors near every VCC pin and provide a solid ground plane under the package. For high-speed designs, observe the published tSU and tCO timing budgets, and consider the IOL/IOH drive strength when driving backplanes or bused signals.

The Altera EPM5192GM-1 is a member of the classic MAX 5000 family of high-speed, high-density programmable logic devices (PLDs), implemented in CMOS technology and housed in an 84-pin ceramic Pin Grid Array (CPGA-84) windowed package that supports in-circuit erasure via UV exposure. It integrates 192 logic cells (equivalent macrocells) and provides a pin-to-pin propagation delay of 55 ns, making it suitable for glue-logic and state-machine replacement in legacy industrial and military systems. A Programmable Logic Device (PLD) is a general-purpose digital integrated circuit whose logic function is defined by the customer after manufacture; PLDs sit hierarchically under FPGAs and CPLDs within the broader programmable logic taxonomy, and historically served as the primary means of implementing random logic before FPGAs became economically dominant. The MAX 5000 family uses EPROM-based non-volatile configuration cells, which means the programmed bitstream is retained when power is removed and the device is reprogrammable only after UV erasure - a key reason these parts are still found in long-lifecycle aerospace and defense equipment. Key features include 192 logic cells, 55 ns propagation delay, CMOS process technology, EPROM programmability with UV-erasable window, ceramic PGA-84 package, and commercial/industrial temperature grade operation. The ceramic CPGA-84 housing provides excellent thermal performance and mechanical robustness for demanding environments. From an architectural standpoint, the EPM5192GM-1 implements the classic AND-OR programmable array structure with a fixed OR array and a programmable AND array. Each macrocell contains flip-flops and output enables, allowing the device to replace multiple discrete 74LS TTL packages with a single IC. Designers use Altera's MAX+PLUS II development environment (legacy software, current users rely on archived versions) to capture schematics, compile, and download JEDEC bitstreams via a programming hardware. Typical applications include industrial control glue logic, military and aerospace avionics subsystems, legacy telecommunications backplane interfacing, state-machine replacement in motor controllers, and bus-interface adaptation in test equipment. The windowed ceramic PGA package is specifically suited to applications where the bitstream may need periodic updates or where MIL-STD or extended-temperature reliability is required. When designing with the EPM5192GM-1, engineers should plan for a UV eraser (typically 254 nm, ~30 minutes exposure) for any in-field reprogramming, and verify that the I/O drive strength matches the connected bus. The device is programmed in-circuit via Altera's ByteBlaster or compatible hardware using JEDEC files generated by MAX+PLUS II.

What is an EPLD? An Erasable Programmable Logic Device (EPLD) is a non-volatile programmable logic component that combines the integration density of early PLDs with the architectural flexibility of more complex PLDs. MAX 5000 devices sit in the product hierarchy as follows: programmable logic device (PLD) -> EPLD -> CMOS EPLD -> MAX 5000 family -> high-density EPLD. MAX 5000 EPLDs were widely used to replace multiple discrete PAL/GAL devices with a single reprogrammable chip, and the ceramic windowed PGA package enabled in-system UV erasure for prototyping and design iteration. Key features of the EPM5192GM-2 include 192 macrocells, a 55 ns propagation delay grade (the -2 speed grade), CMOS low-power operation, and pin compatibility across the MAX 5000 macrocell range. The 84-pin ceramic PGA package supports the wide I/O count required for bus-interface and datapath applications while providing hermetic environmental protection suitable for military temperature ranges. Architecturally, the device integrates a programmable AND/OR array feeding 192 macrocells, each with configurable flip-flops, plus a global interconnect that routes signals across the chip with predictable, deterministic timing. The CMOS implementation delivers substantially lower power than the bipolar PLDs that preceded the MAX 5000 family, and the UV window allows laboratory erasure and reprogramming during development cycles. Typical applications include military and aerospace systems (the -2 speed grade and ceramic package support defense-grade designs), industrial control glue logic, telecommunications interface bridging, and legacy replacement of multiple 22V10-class PALs. The 84-pin ceramic PGA is also favored in space and avionics where hermetic packaging and known-good-die reliability are required. When designing with this part, verify availability through franchised distributors before committing to a new design. The MAX 5000 family is mature, and long-term production status should be confirmed against Intel's product longevity program for military and aerospace programs requiring multi-decade supply commitments.

It supports asynchronous, synchronous, and registered clocking architectures and is fully supported by MAX+PLUS II and Quartus design environments for legacy designs. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic IC that preceded modern CPLDs and FPGAs, offering fast deterministic propagation delay, low power, and one-time or erasable programming. EPLDs belong to the broader category of programmable logic devices (PLDs), which sit hierarchically within logic ICs -> programmable logic -> digital semiconductors. The MAX 5000 architecture extends classic PAL/GAL logic with macrocell-based sum-of-products implementation, programmable interconnect, and JTAG-supportable test features. Compared with SRAM-based FPGAs, the EPM5192's EPROM cells retain configuration without external boot memory, while compared with pure PALs it offers 5-10x higher logic density and predictable timing. Key features of the EPM5192GM-2/883B include 192 macrocells (768 usable gates), 55 ns tPD, 80 MHz fCNT, 192 flip-flops, 16 LABs, dedicated input and global clock networks, 5 V VCC single supply, in-system programmability via ByteBlaster, JTAG support through the legacy JTAG block, and a 100 mA typical operating current. The ceramic windowed PGA-84 package provides hermetic environmental protection for military and aerospace applications, where the MIL-STD-883B screening guarantees operation across -55C to +125C and resilience against thermal, mechanical, and solder-shock stresses. Architecturally, the EPM5192 uses a programmable-AND/fixed-OR PLA-like macrocell structure where each macrocell contains 5 product terms (expandable to 20 via parallel expanders) feeding a D flip-flop with programmable clock, preset, clear, and output enable. The 16 LABs each contain 12 macrocells and a global interconnect that routes signals between LABs through a fixed but high-fanout network. This architecture delivers short, predictable propagation delays independent of design complexity, contrasting with the routing-dependent timing of SRAM FPGAs. Typical applications for the EPM5192GM-2/883B include military and aerospace digital control systems, defense electronics modules requiring MIL-STD-883B screening, industrial control logic, legacy bus arbitration and address decoding, telecommunications backplane glue logic, and avionics line-replaceable units (LRUs). Engineers use it as a deterministic state-machine and decoder platform where both radiation-tolerant/hi-rel packaging and 5 V tolerance are required. When designing with this part, verify power sequencing (no hot-plug), confirm ByteBlaster programming voltage levels (VPP = 12 V during in-system programming), and observe the PGA-84 socket footprint clearance requirements.
EPM5192GM/883 - 192-Cell MAX 5000 UV PLD, 55ns, CPGA-84 | Altera
The Altera EPM5192GM/883 is a high-density, high-speed ultraviolet-erasable programmable logic device (UV PLD) from the classic MAX 5000 family, packaged in an 84-pin ceramic pin-grid array (CPGA-84) with a quartz window for in-system erasure. According to the manufacturer datasheet family description, it integrates 192 logic macrocells and delivers a maximum pin-to-pin propagation delay of 55 ns, combining the integration density of a gate array with the design flexibility of a UV-erasable PLD. A UV PLD (ultraviolet-erasable programmable logic device) is a non-volatile logic IC whose internal fuse/anti-fuse interconnect matrix can be erased by exposing the die through an integral quartz window to high-intensity UV light, then re-programmed. The MAX 5000 family sits in Altera's hierarchy of EPLDs (erasable programmable logic devices) -> PLDs -> programmable logic -> digital logic ICs -> integrated circuits, and represents the company's first high-density CMOS EPLD architecture. UV PLDs such as the EPM5192GM/883 were widely adopted for low-volume military, aerospace, and industrial control applications where design iteration was required but field reprogrammability had to be non-electronic (immune to accidental erasure and to firmware upset from EMI/ESD). Key differentiating specifications include 192 logic macrocells, 55 ns maximum pin-to-pin delay (Tpd), and 84-pin ceramic PGA packaging. The 883 suffix designates compliance with MIL-STD-883 Class B processing for high-reliability military and aerospace environments. The device is fabricated in CMOS technology, offering low static power consumption relative to the bipolar PAL alternatives of its generation. It provides a register-rich architecture suited to state machines, glue logic, address decoding, and bus-interface functions in mainframe, telecom, and avionics systems. Typical applications include military/aerospace avionics control logic, industrial programmable controllers, address decoding and bus-interface glue logic in legacy mainframe and telecom backplanes, and prototype development for ASIC replacement. Designers select the EPM5192GM/883 when the design must survive MIL-STD-883 environmental stress screening and when in-system reprogramming through the quartz window is acceptable for the deployment scenario. When designing with this device, note that the ceramic CPGA-84 package requires a through-hole socket or PCB with plated-through holes; surface-mount assembly is not supported. Plan for an EPROM eraser (UV source) if field reprogramming is anticipated, and observe the maximum junction temperature and supply-voltage derating curves from the datasheet when operating outside the commercial temperature range. Designers should also evaluate newer MAX 7000/MAX 3000A in-system-programmable (ISP) alternatives when UV-erase capability is not a hard requirement, as those parts eliminate the eraser step.

EPM5192GM/883B - 192-Cell UV PLD, 55ns MAX 5000 PGA-84 | Altera
The Altera (Intel) EPM5192GM/883B is a 192-cell, 55 ns ultraviolet-erasable programmable logic device (UV PLD) from the legacy MAX 5000 family, supplied in a 84-pin ceramic windowed Pin Grid Array (CPGA-84, also called PGA-84) package and qualified to MIL-STD-883 Class B for high-reliability and military-aerospace programs. A UV-erasable PLD is a non-volatile programmable logic device whose configuration is stored in floating-gate memory cells and erased by exposing the die through a transparent quartz window to short-wave ultraviolet light. PLDs sit beneath FPGAs and CPLDs in the programmable-logic hierarchy; they implement glue logic, state machines, and decoder functions in fixed-OR / programmable-AND arrays. MAX 5000 devices specifically use CMOS EEPROM-style programming cells wrapped in a bipolar-compatible I/O structure, giving them higher density than 22V10-class devices while remaining erasable in-system via UV. Key features include 192 logic macrocells (each combining a programmable AND array, a flip-flop, and an I/O buffer), a pin-to-pin propagation delay of 55 ns at the commercial 5 V VCC specification, and a total of 64 dedicated I/O pins plus dedicated clock, output enable, and clear inputs. The device is fabricated in 1.2 µm CMOS with an on-chip charge pump, eliminating the need for an external high-voltage programming supply. The /883B suffix indicates 883 Method 5004/5005 Class B screening, so the part is qualified to operate across the full military -55 °C to +125 °C temperature range. Typical applications include avionic flight-control interface boards, military ground-vehicle wiring-replacement modules, naval combat-system signal conditioning, and any high-reliability platform where an in-system-reprogrammable UV device is preferred over a one-time-programmable (OTP) or mask-ROM part. The windowed ceramic PGA allows laboratory and field erasure plus re-programming cycles, which is essential for prototype debug on flight hardware. When designing with the EPM5192GM/883B, observe the standard UV-PLD guidelines: maintain a high-frequency ground-return path, keep the ceramic body above a grounded copper pad for thermal relief, and route programming signals to the top side of the board so the device can be socketed and re-erased without depopulation. /883B variants require lot-traceability documentation and ESD precautions per MIL-STD-1686.
