EPM5192AGC-15 - 192-Macrocell MAX 5000 EPLD | Altera | 15ns
The Altera EPM5192AGC-15 is a high-density, UV-erasable erasable programmable logic device (EPLD) from the classic MAX 5000 family, delivering 192 macrocells, 72 inputs, and a 15 ns pin-to-pin propagation delay in a ceramic PGA package. It belongs to the MAX 5000 series of high-speed, high-density CMOS EPLDs that brought register-rich programmable logic to bus-interface, glue-logic, and state-machine designs in the 1990s and early 2000s. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that uses EPROM/EEPROM storage cells to retain configuration, positioned hierarchically between a PAL/GAL (simple PLD) and a true FPGA. Within the broader taxonomy of programmable logic, EPLDs sit above simple PLDs but below FPGAs in logic density, while offering predictable timing and instant-on behavior at power-up. The MAX 5000 family is the legacy Altera product line that preceded the MAX 7000/MAX II families; devices are programmed via a JTAG-style or dedicated programming interface and are commonly supplied in windowed ceramic packages for prototype/development use. Key specifications include 192 macrocells organized in logic array blocks, 64 I/O pins plus 7 dedicated input pins for a total of 72 inputs, a 15 ns worst-case pin-to-pin propagation delay (-15 speed grade), and CMOS technology operating from a 5 V supply. The device supports in-system programmability through the Altera programming hardware, and the ceramic PGA package is windowed for UV erasure during development. Compared with its slower siblings (EPM5192AGC-20 at 20 ns and EPM5192AGC-25 at 25 ns), the -15 speed grade is the fastest variant in the family and is targeted at high-speed bus-interface applications. Typical applications include 32-bit microprocessor bus decoding, state-machine controllers, address decoding for memory subsystems, and replacement of multiple discrete TTL/CMOS glue-logic packages. The high input count (72 inputs) makes the EPM5192 well suited to monitoring multiple control signals in parallel, while the predictable 15 ns delay allows replacement of multiple 74LS/74F-series decoders with a single device. When designing with this part, ensure that the 5 V VCC supply is well decoupled and that the ceramic PGA socket accommodates the device's pin pattern. Note that the EPM5192 family is mature/legacy; new designs typically migrate to MAX 7000AE or MAX II devices, and long-term availability is constrained. This page synthesizes distributor pricing, drop-in alternative guidance, and practical design notes that complement the Altera datasheet and help engineers source or replace this legacy EPLD in maintenance and modernization projects.
EPM5192AGC-20 - MAX 5000 EPLD, 192 Macrocells | Altera (Intel)
The Intel (formerly Altera) EPM5192AGC-20 is a high-density, high-speed CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, providing 192 macrocells and 12,000 usable gates in a ceramic-windowed PGA (Pin Grid Array) ceramic package. It operates at a 20 ns pin-to-pin propagation delay, making it suitable for glue-logic, bus-interface, and high-speed state-machine replacement of multiple discrete TTL/CMOS devices. A MAX 5000-series EPLD is a member of the electrically-erasable programmable logic device (EEPLD) family. In the broader component taxonomy, an EPLD sits under programmable logic devices (PLDs) -> programmable logic -> digital logic ICs. MAX 5000 devices use a programmable AND/OR macrocell architecture with non-volatile EEPROM configuration memory, so designs retain their pattern after power-down without an external boot PROM - unlike SRAM-based FPGAs which require a configuration flash. Each macrocell contains a programmable AND plane feeding a fixed OR term, an output register, and a feedback path, allowing both combinatorial and registered logic to be implemented. Key features of the EPM5192 include 192 macrocells, 12,000 usable gates, a 20 ns tPD (pin-to-pin delay), fCNT up to 100 MHz counter frequency, and 96 dedicated I/O pins organized into 8 LABs (Logic Array Blocks). Per the Altera MAX 5000 datasheet, the device supports 5 V in-system programmability via the IEEE 1149.1 JTAG interface, allowing reconfiguration without removal from the board. An enhanced security bit prevents pattern read-back, protecting proprietary designs. Typical applications include high-speed glue logic between microprocessors and peripherals, bus arbitration and address decoding, state-machine replacement for legacy 74LS/74F TTL, and industrial control sequencers. The 20 ns tPD makes it appropriate for systems clocked up to ~33 MHz without pipeline insertion. When designing with the EPM5192AGC-20, verify that the target application does not exceed 5.5 V VCC. Use a ceramic-socketed PGA footprint to take advantage of windowed UV erasure during prototyping. The ceramic 'G' package is rated for commercial 0C to 70C operation; for industrial temperatures use the equivalent -1 or -2 speed grade in a plastic package.
EPM5192AGC84-15 - 192-Macrocell UV PLD, 15ns | Altera MAX 5000
The Altera EPM5192AGC84-15 is a 192-macrocell UV-Erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, housed in an 84-pin Ceramic PGA (Pin Grid Array) package. This CMOS device provides 192 logic macrocells organized into 12 Logic Array Blocks (LABs), 64 user I/O pins, and 7 dedicated inputs, supporting combinational and registered logic with a propagation delay of 15 ns (commercial grade) and a maximum internal clock frequency of 83.3 MHz. It operates from a single 4.5 V to 5.5 V supply, with the -15 speed grade denoting a 15 ns pin-to-pin delay. What is a UV-erasable/OTP PLD? A UV-Erasable Complex PLD (Programmable Logic Device) is a non-volatile, one-time-programmable logic IC whose AND/OR array fuse links can be cleared by exposing the die to ultraviolet light through a quartz window, then re-programmed in a dedicated device programmer. The OTP suffix indicates one-time programmable packaging without an erasure window, while the UV variant retains the quartz lid. The MAX 5000 sits in the historical taxonomy: PLD -> CPLD (Complex PLD) -> MAX family -> UV-erasable high-density logic, predating modern SRAM-based FPGAs. Key features include 192 macrocells with configurable D/T/JK flip-flops, 64 bidirectional I/O lines with TTL/CMOS-compatible thresholds, an internal global clock network with synchronous/asynchronous operation, and a 5 V CMOS process that delivers 15 ns propagation delay with low power consumption. The 84-pin ceramic PGA package offers robust thermal performance for industrial and military temperature grades. Architecturally, the MAX 5000 family uses a sum-of-products PLA structure with distributed AND/OR arrays feeding each macrocell, allowing up to 32 product terms per macrocell. The 12 interconnected LABs provide high integration density for glue logic, address decoding, bus arbitration, and state-machine consolidation in 5 V systems. Typical applications include 5 V bus-interface glue logic, address decoding and interrupt priority encoding in 8086/Motorola 68000 systems, state-machine and sequencer consolidation in industrial controllers, and high-reliability avionics and military systems requiring UV-reprogrammable logic. The -15 speed grade (15 ns tPD) suits most glue-logic tasks where 25 ns devices would be too slow. When designing with this part, note that the 84-pin ceramic PGA package requires a through-hole socket and is significantly larger than modern QFP/BGA CPLDs; verify PCB layout and programmer compatibility before specifying. The CMOS process requires careful ESD handling during programming and in-system integration.
EPM5192AGC84-20 - 192-Macrocell MAX 5000 UV PLD | Altera | 84-CPGA
The Altera EPM5192AGC84-20 is a CMOS UV-Erasable/OTP Complex Programmable Logic Device (PLD) from the Altera MAX 5000 family, packaged in an 84-pin Ceramic Pin Grid Array (CPGA, package code WPGA) and qualified for commercial temperature grading. It integrates 192 macrocells, 64 user I/O lines, and 7 dedicated inputs, and is rated for a maximum clock frequency of 66.7 MHz with a 20 ns pin-to-pin logic delay. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on semiconductor that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix on a single die. CPLDs sit between discrete TTL/CMOS glue logic and larger FPGAs in the programmable-logic hierarchy: PLD -> CPLD -> FPGA -> programmable logic. They are valued for deterministic timing, zero-configuration latency, and high pin-to-pin drive strength, which makes them ideal for address decoding, bus interfacing, and state-machine replacement in legacy industrial designs. Key features of the EPM5192AGC84-20 include 192 macrocells (delivering up to ~7,500 usable gates), 64 bi-directional I/O pins organized into 4 I/O banks, 7 dedicated global input pins (GCLK, OE1, OE2, OE3, OE4, CLR, PRE), in-system UV-erase window (ceramic package), and 5-Volt CMOS I/O compatible with TTL levels. The "-20" speed grade corresponds to tPD = 20 ns and fMAX = 66.7 MHz. The device is built on Altera's classic MAX (Multiple Array matriX) architecture, which arranges macrocells into Logic Array Blocks (LABs) connected by a continuous programmable interconnect. The ceramic CPGA package is hermetic and UV-transparent, allowing erasure under a UV lamp; an OTP window is included for production programming. The design supports both combinatorial and registered logic with per-macrocell D/T/JK flip-flop configuration. Typical applications include legacy bus-interface glue logic in industrial controllers, address decoding for microprocessor and DSP systems, peripheral replacement (decoders, multiplexers, state machines), and prototype-to-production migration where deterministic timing and instant-on behavior are required. Its 84-pin CPGA is also well suited to through-hole industrial backplanes and military-style card cages where ceramic packaging is preferred. When designing with this part, verify that the CPGA land pattern matches your socket or PCB footprint; ceramic CPGA sockets are specialty items and may have long lead times. For new designs, modern Altera/Intel MAX II or MAX V devices in PLCC/QFP packages are recommended, but the EPM5192AGC84-20 remains the canonical drop-in for legacy systems requiring UV erase.

EPM5192AJC-15 - MAX 5000 EPLD, 192 Macrocells, PLCC-84 | Intel
The Intel (formerly Altera) EPM5192AJC-15 is a high-density, high-speed Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, delivering 192 macrocells, 100% connectivity, and a 15 ns pin-to-pin logic delay in a 84-pin PLCC (J-lead) package. The part operates from a 5 V supply and supports in-system programmability via Altera's MAX+PLUS II development environment, making it a drop-in upgrade for legacy MAX 5000 designs. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic component that combines AND/OR arrays with output macrocells, bridging the architectural gap between simple PLDs and complex CPLDs. The MAX 5000 family sits in the broader taxonomy of programmable logic: programmable logic -> CPLD/EPLD -> MAX family -> MAX 5000 series, and historically served glue-logic, bus-interface, and state-machine roles before being superseded by modern MAX II, MAX V, and MAX 10 devices that use LUT-based architectures and flash or SRAM configuration. Key features include 192 macrocells, 100% connectivity, 15 ns combinational propagation delay (tPD), a 5 V VCC tolerance on I/O, and an ultraviolet-erasable windowed package (the "W" variant is windowed; the J-lead ceramic PLCC "JC" is non-windowed production package). The architecture provides up to 4 product terms per macrocell with a configurable XOR gate for polarity control, allowing efficient implementation of wide AND-OR-INVERT logic functions. Densities in the family range from 32 to 192 macrocells, and the EPM5192 sits at the top of the MAX 5000 density range. The MAX 5000 architecture uses a sum-of-products PLA structure with a global interconnect that guarantees 100% routability of all logic - a hallmark Altera design differentiator versus PAL-style fusemap devices. This deterministic routing eliminates place-and-route iterations common in modern FPGA flows and allows the MAX+PLUS II fitter to deliver consistent timing closure across revisions. The trade-off is lower logic density and higher per-macrocell cost versus LUT-based FPGAs, but for legacy 5 V designs the MAX 5000 family remains a proven, long-lived platform. Typical applications include legacy 5 V bus-interface glue logic, address decoding and chip-select generation, state-machine and sequencer logic, peripheral controllers in industrial and telecom backplanes, and replacement of multiple discrete PAL/GAL devices. The 84-pin PLCC package and 5 V operation also make the EPM5192AJC-15 compatible with older through-hole and socketed designs where board rework is impractical. When designing with this device, ensure the MAX+PLUS II toolchain (or modern compatible programmer) is available and verify availability of a 5 V source. Note that Intel/Altera MAX 5000 devices have been in maintenance status for many years; verify long-term supply before new designs. The "-15" speed grade corresponds to a 15 ns tPD; the "-20" and "-25" grades are slower and may be substituted in non-timing-critical sockets.

EPM5192AJC-25 - MAX 5000 192-Macrocell EPLD, 25ns | Altera
The Intel / Altera EPM5192AJC-25 is a 192-macrocell, high-density, high-speed Erasable Programmable Logic Device (EPLD) from the legacy MAX 5000 family, housed in a 68-pin PLCC (AJC) windowed ceramic package with 25 ns pin-to-pin propagation delay. The MAX 5000 family was Altera's second-generation EPLD architecture, offering non-volatile UV-erasable programmability, predictable timing, and 5 V tolerant CMOS I/O targeted at glue-logic, bus-interface, and state-machine integration in through-hole industrial designs. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines AND/OR array architecture with macrocell-based output logic, falling within the broader hierarchy of programmable logic devices (PLD) -> EPLD/CPLD -> complex programmable logic. EPLDs sit between simple PAL/GAL devices and modern SRAM-based FPGAs in terms of density and are characterized by deterministic propagation delay that does not depend on routing path length - a critical property for asynchronous bus interfaces and decoder logic. Key features include 192 macrocells organized into multiple Logic Array Blocks (LABs), 100% factory-tested operation, 5 V CMOS I/O with TTL-compatible inputs, programmable output macrocells with configurable flip-flops, and a maximum propagation delay of 25 ns (tPD). The ceramic windowed PLCC package supports UV erasure for prototype and development cycles, while the AJC suffix denotes the PLCC-68 ceramic windowed form factor with industrial-grade operating temperature range. The MAX 5000 architecture uses a classic EPROM-based AND/OR plane feeding output macrocells with selectable registered/combinational modes. Unlike SRAM-based FPGAs, the device requires no external boot PROM, powers up in a defined state, and retains configuration indefinitely. The 25 ns speed grade positions this part for legacy 25-33 MHz bus interfaces rather than modern high-speed designs. Typical applications include legacy PC/AT bus decode logic, peripheral controllers (DMA, interrupt, bus arbitration), industrial state machines, military/aerospace systems (the J-grade marking indicates MIL-STD-883 processing), and prototyping platforms for newer MAX 7000/MAX II designs. Engineers working on long-lifecycle defense and aerospace equipment frequently retain MAX 5000 designs due to form-fit-function stability. When designing with this EPLD, ensure the propagation delay budget accounts for both tPD and tCO (clock-to-output) timing - consult the datasheet for the exact derating curves at junction temperatures above 70°C. UV erasure requires a windowed ceramic package; production plastic-package equivalents (EPM5192AQI, EPM5192AQC) offer one-time programmable (OTP) replacements with identical footprint but no window.

EPM5192AJC84-15 - MAX 5000 CPLD, 192 Macrocells, 84-pin PLCC | Altera
The Altera EPM5192AJC84-15 is a UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the MAX 5000 family, featuring 192 macrocells in an 84-pin PLCC (J84C) windowed ceramic package. It operates from a single 5V supply with a propagation delay of 15 ns and a maximum clock frequency of 83.3 MHz, making it suitable for high-speed glue-logic and state-machine integration. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple SPLDs/GALs and large FPGAs in the programmable logic hierarchy (SPLD -> CPLD -> FPGA -> programmable logic). It typically contains multiple PAL-like logic blocks interconnected by a central programmable switch matrix, with non-volatile storage that retains configuration without external memory. The MAX 5000 family was Altera's second-generation high-density EPLD line (the second 'M' family), succeeding the classic MAX 7000 and MAX 3000 lines that became industry workhorses for bus-interface and address-decoding glue logic. Key features include 192 macrocells (each containing a programmable AND/OR array with a flip-flop), 5V CMOS technology, UV-erasable windowed package for re-programmability, and pin-to-pin compatibility across the MAX 5000 series. The 15 ns propagation delay supports synchronous designs up to the rated 83.3 MHz fMAX, and the device supports both combinatorial and registered logic through its macrocell register option. Architecturally, the EPM5192 uses a classic sum-of-products PLA structure with a global interconnect matrix that delivers consistent, deterministic timing across all 192 macrocells. The CMOS EPROM-based configuration cell stores the logic pattern, and the ceramic windowed package (designated 'JC' with quartz window for UV erasure) is intended primarily for prototype development; production units typically migrate to the plastic 'PC' one-time-programmable package. Typical applications include bus address decoding, state-machine controllers, glue logic between microprocessors and peripherals, and legacy industrial-control designs. The wide 5V tolerance also makes it useful as a level shifter between TTL and CMOS logic families on legacy backplanes. When designing with the EPM5192, ensure the 5V VCC rail is well-decoupled with 0.1 uF ceramic capacitors near each supply pin, and verify that all inputs respect the 5.5V absolute maximum rating. For new designs, consider that the MAX 5000 family is mature/EOL — confirm long-term availability before committing to volume production.

EPM5192AJC84-20 - 192-Macrocell UV PLD, 33ns, 84-Pin J-Lead | Altera
The Altera EPM5192AJC84-20 is a 192-macrocell UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the MAX 5000 family, housed in an 84-pin Plastic Leaded Chip Carrier (PLCC J-Lead, WQCCJ) package with a 33 ns propagation delay and a 66.7 MHz maximum clock frequency. It operates from a single 4.75 V to 5.25 V supply, offers 7 dedicated inputs and 64 user I/O lines, and is fabricated on a CMOS UV-erasable switch-matrix process that allows in-system erasure and re-programming using an ultraviolet lamp. What is a UV-erasable CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on digital IC that implements glue logic, bus arbitration, state machines, and address decoding in a single chip. The UV-erasable (windowed) variant adds a quartz window above the die that lets an external UV lamp reset the on-chip EEPROM-like switches, so the same physical package can be re-programmed many times during prototyping. Within the broader taxonomy, a CPLD belongs to programmable logic devices (PLD), which themselves sit under digital logic ICs and semiconductor devices. Key features include 192 macrocells arranged in Logic Array Blocks (LABs), a programmable interconnect switch matrix, 64 bidirectional I/O pins, 7 dedicated clock/input pins, and a 33 ns pin-to-pin delay (the “-20” speed grade). The device is built on a CMOS EEPROM technology that delivers deterministic propagation delay regardless of logic utilization, which is critical for synchronous designs. Architecturally, the EPM5192 integrates the AND/OR array with output macrocells that contain programmable flip-flops, making it well suited for both combinatorial and registered designs. The UV window enables up to thousands of erase/reprogram cycles during development, although the part is one-time-programmable once the window label is removed for production. Typical applications include glue logic for legacy 5 V microprocessor and DSP systems, bus-interface and address-decoding logic, peripheral controllers in industrial control, and replacement of multiple 74-series TTL/CMOS gates in compact boards. Designers of long-life industrial and military systems also rely on this part for its deterministic timing and field-proven reliability. Designers should plan a 10–15 percent I/O and macrocell margin, use Altera MAX+PLUS II or Quartus for design entry, and budget for the UV-erase cycle (~30 minutes under a 12,000 uW/cm² lamp) if iterative prototyping is required. The 84-pin J-lead PLCC accepts standard socket or surface-mount footprints, easing both production and rework.
EPM5192AJI84-15 - 192-Macrocell UV PLD, 15ns | Altera
The Altera EPM5192AJI84-15 is a UV-erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 EPLD family, featuring 192 macrocells, 84 user I/O pins, and a propagation delay of 15 ns, housed in an 84-pin J-lead ceramic (JLCC) package. This CMOS device operates from a nominal 5 V supply (4.5 V to 5.5 V) and supports high-density glue-logic integration for legacy and industrial systems. A Programmable Logic Device (PLD) is a class of digital integrated circuit whose logic function and interconnect are defined by on-chip programmable fuses, anti-fuses, or floating-gate memory cells rather than at the mask level. In the broader system hierarchy, PLDs sit between discrete TTL/CMOS glue logic and mask-programmed gate arrays: they offer higher integration than 74-series logic, lower NRE cost than full ASICs, and faster iteration cycles than mask-programmed gate arrays. The MAX 5000 family's UV-erasable windowed package made it a 1990s workhorse for prototyping and low-volume production. Key features of the EPM5192AJI84-15 include 192 macrocells organized as 16 Logic Array Blocks (LABs) of 16 macrocells each, 84 bi-directional I/O pins, a 15 ns pin-to-pin propagation delay (tPD) enabling 50 MHz+ state-machine operation, and an internal 5 V CMOS EPROM process technology. The 'J' suffix indicates the JLCC (J-Leaded Ceramic Chip Carrier) windowed package, and 'I' designates the industrial operating temperature range of -40 °C to +85 °C. The architecture combines a global programmable interconnect array with LAB-local routing, allowing efficient implementation of wide combinational and registered logic functions such as address decoders, bus arbitrators, state machines, and peripheral controllers. The 84-pin JLCC package with quartz window supports UV erasure for re-programming during development, after which the device is typically windowed-over or replaced with the OTP 'C' (plastic) variant for production. Typical applications include legacy 5 V system glue logic, industrial control and instrumentation, military and aerospace prototyping (where MIL-STD-883 variants exist), telecom backplane controllers, and field-replaceable logic modules. The wide 5 V supply tolerance and high I/O count make it well-suited to bus-interface and address-decoding tasks in 8-/16-bit microprocessor systems. When designing with this part, verify that downstream tooling (MAX+PLUS II baseline or legacy Altera designers) is available, since modern Quartus Prime does not support the MAX 5000 family. Decoupling per MAX 5000 reference designs and respect for the UV-erase programming sequence are essential for first-time-programming success.

EPM5192AJI84-20 - 192-Macrocell UV EPLD, 33ns | Altera MAX 5000
The Altera EPM5192AJI84-20 is a UV-erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, delivering 192 macrocells in an 84-pin ceramic J-leaded chip carrier (PLCC-84, package code JI) with a 33ns propagation delay and 66.7 MHz maximum clock frequency. This CMOS device operates from a nominal 5 V supply across a 4.5 V to 5.5 V range, suiting legacy 5 V logic designs that require high integration without an FPGA-grade architecture. A Programmable Logic Device (PLD) is a class of digital integrated circuit that allows engineers to implement custom combinational and sequential logic by configuring on-chip macrocells, instead of committing to a fixed ASIC. The hierarchy is PLD -> Complex PLD (CPLD) -> MAX-class EPLD -> programmable logic -> digital IC. The MAX 5000 family in particular pioneered UV-erasable, high-density logic with EEPROM-style macrocells, targeting glue-logic, bus interfacing, and state-machine consolidation that previously consumed multiple SSI/MSI packages. Key features of the EPM5192AJI84-20 include 192 macrocells, 33 ns pin-to-pin propagation delay (tPD), 66.7 MHz maximum frequency (fCNT), and a wide 5 V supply tolerance of 4.5 V to 5.5 V. The device is offered in the industrial temperature grade and is packaged in an 84-pin J-bend ceramic chip carrier, identified in the JEDEC code as WQCCJ. As a UV-erasable part, the device can be reprogrammed after package-window UV exposure, which made it useful for prototyping where design revisions were anticipated. Architecturally, the EPM5192AJI84-20 uses Altera's Classic macrocell with a programmable AND/OR array feeding a configurable flip-flop. Logic is compiled into sum-of-products form and routed through the Labyrinth interconnect, which balances pin-assignment flexibility against timing predictability. Because every path traverses the same global interconnect, propagation delay is essentially independent of logic placement, simplifying static timing analysis on 33 ns designs. Typical applications include 5 V TTL/CMOS glue logic, address decoding and bus arbitration for Intel 80-series and Motorola 68k microprocessors, peripheral interface controllers (GPIB, SCSI, UART), industrial state machines, and pin-compatible replacement of discrete 74LS/74F logic. Designers also used the EPM5192AJI84-20 as a single-chip replacement for multiple PAL/GAL devices in long-life-cycle industrial systems. When designing with the EPM5192AJI84-20, plan the logic to fit within 192 macrocells before compile; over-mapping typically requires stepping down to a smaller member of the MAX 5000 family. UV erasure requires a 12,000 uW-sec/cm^2 dose, so production systems usually migrate to one-time-programmable (OTP) MAX 7000/MAX 3000 successors for un-windowed packages. This page synthesizes distributor stock, J-bend footprint notes, MAX 5000 family cross-references, and practical design notes not consolidated in the original Altera datasheet, supporting engineers maintaining legacy 5 V platforms through 2026.
EPM5192AJM84-15 - 192-Macrocell UV PLD MAX 5000 | Altera
The Altera EPM5192AJM84-15 is a 192-macrocell UV-erasable programmable logic device (PLD) from the classic Altera MAX 5000 family, supplied in an 84-pin ceramic J-lead (JM84) package. The -15 speed grade corresponds to a 15 ns pin-to-pin propagation delay, supporting a maximum clock frequency of 83.3 MHz. Built on a 5 V CMOS EPROM-style architecture, the EPM5192AJM84-15 provides high-density combinatorial and registered logic with non-volatile configuration that can be erased by exposure to ultraviolet light and re-programmed many times. A Programmable Logic Device (PLD) is a class of digital integrated circuit whose internal logic array and interconnects are defined by the user after manufacture, replacing dozens of discrete TTL/CMOS glue-logic packages. The MAX 5000 family sits in the hierarchy as a high-density PLD, above simple PAL/GAL devices but below modern FPGA architectures, optimized for state-machine, bus-interface, address-decoding and peripheral-control applications. The 192-macrocell capacity of the EPM5192 places it in the upper tier of the MAX 5000 lineup, second only to the EPM5192A-family devices with the same density. Key features of the EPM5192AJM84-15 include 192 logic macrocells, 84 user I/O pins routed through the JM84 J-lead ceramic package, 15 ns propagation delay, 83.3 MHz maximum operating frequency, and a -55C to +125C military-grade operating temperature range (the 'JM' suffix denotes the JAN/MIL ceramic J-lead variant). The device is supplied as a windowed ceramic package for laboratory, aerospace, and defense applications where the ability to erase and re-program the configuration memory in-circuit or via UV exposure is required for design iteration or field upgrades. The MAX 5000 architecture uses a programmable AND/OR array with a fixed-OR, programmable-macrocell output stage; each macrocell can be configured as a D-flip-flop, T-flip-flop, or pure combinatorial output. The I/O structure is JTAG-friendly, with input registers, I/O registers, and buried registers available to absorb pipelined designs without sacrificing pin count. The chip is supported by the Altera MAX+PLUS II development environment for design entry, fitting, simulation, and programming. Typical applications for the EPM5192AJM84-15 include military and aerospace control systems, industrial bus-interface logic, address decoding for legacy processor boards, DRAM/PCI bus controllers, and other high-reliability systems requiring high-density PLD logic. The ceramic JM84 package also makes the part well suited to defense programs where MIL-PRF-38535-qualified parts are required. When designing with the EPM5192AJM84-15, allow generous decoupling (100 nF ceramic at every VCC/ground pair), follow standard CMOS anti-static handling during UV erasure, and verify timing margins against the 15 ns tPD specification across process and temperature corners.

EPM5192AJM84-20 - 192-Macrocell UV PLD, CQFP-84 | Altera
The Altera EPM5192AJM84-20 is a CMOS UV-erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, delivering 192 macrocells organized into 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). Housed in an 84-terminal Ceramic Quad Flat Pack (CQFP) with J-leads, this MIL-grade variant operates at a maximum clock frequency of 66.7 MHz with a propagation delay of 33 ns. A Complex Programmable Logic Device (CPLD) is a non-volatile, reprogrammable semiconductor that combines multiple PAL-like macrocell blocks on a single die, connected through a centralized interconnect matrix. PLDs sit in the programmable-logic hierarchy below FPGAs but above discrete glue logic, providing deterministic timing, instant-on behavior, and high drive strength for bus interface, state-machine, and decoder applications. Key features of the EPM5192AJM84-20 include 64 user I/O lines, 7 dedicated inputs, a maximum toggle frequency of 66.7 MHz, a pin-to-pin logic delay of 33 ns via -20 speed grade, and an extended operating temperature range suitable for military applications. The architecture uses EPROM/UV-erasable cells, allowing field reprogramming after package-window UV exposure. The device is built on a CMOS EEPROM process with Altera's classic MAX architecture, in which each LAB contains 16 macrocells feeding the PIA. This delivers fast, predictable combinatorial and registered logic with no hidden routing delays. The JEDEC S-CQCC-J84 CQFP package provides hermetic sealing for harsh-environment deployment, with a windowed ceramic lid enabling UV erasure. Typical applications include military and aerospace control logic, radiation-tolerant interface glue, legacy bus-arbiter replacement, vintage telecommunications backplanes, and industrial test equipment requiring MIL-spec plastic alternatives. The CQFP-84 footprint is also well-suited for retrofit boards originally designed around MAX 5000-series devices. When designing, allocate a UV erasure window budget: quartz-windowed ceramic packages must be erased with 12,000 uW-s/cm² of UV-C (253.7 nm) before reprogramming, and OTP variants cannot be re-programmed. The MIL temperature grade and hermetic CQFP package require careful PCB footprint matching to the 84-pin J-lead land pattern.

EPM5192ALC84-15 - 192-Macrocell MAX 5000 EPLD, 15ns | Altera
The Altera EPM5192ALC84-15 is a UV-erasable / OTP Complex Programmable Logic Device (CPLD) from the MAX 5000 family, providing 192 macrocells, 64 user I/O pins, and a 15 ns pin-to-pin propagation delay. Implemented in a 5 V CMOS process, it operates from a 4.75 V to 5.25 V supply and is housed in an 84-pin ceramic J-lead chip carrier (PLCC-84). According to the MAX 5000 datasheet family, the device integrates a programmable AND/OR/INVERT logic array with macrocell registers and a deterministic interconnect, enabling designers to replace 20-plus discrete SSI/MSI packages with a single non-volatile logic solution. What is a Complex PLD (CPLD)? A CPLD is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell blocks on one die with a centralized programmable interconnect matrix (PIA). CPLDs sit between discrete gate arrays and FPGAs in the programmable logic hierarchy: PLD -> CPLD -> programmable logic -> semiconductor. Their key advantages are deterministic timing, instant (zero-power) power-on, and excellent pin-to-pin compatibility across speed grades. Key features of the EPM5192ALC84-15 include 7 dedicated inputs feeding a high-drive bus, 192 macrocells (each with a flip-flop and product-term allocation), 64 bidirectional I/O pins with 5 V tolerant interfaces, and a 15 ns combinatorial propagation delay at 5 V. Built on the mature EPROM-based MAX 5000 architecture, it offers one-time-programmable (OTP) or UV-erasable behavior with no configuration memory required. The MAX 5000 architecture places logic signals through a Programmable Interconnect Array (PIA) that guarantees a fixed, predictable delay independent of the routed path. This contrasts with SRAM-based FPGAs whose routing delays are data-dependent, making the EPM5192ALC84-15 a strong fit for fast control and decode functions where timing closure is critical. Typical applications include bus-address decoding and glue logic in VME/PCI/ISA backplanes, high-speed state-machine controllers, peripheral-interface adapters for motor drives, military/aerospace systems (per MIL-STD-883C processing on the ceramic QCCJ package), and replacement of multi-gate SSI/MSI logic in long-lifecycle industrial designs. When designing with this device, allocate product terms per macrocell carefully: the 192-macrocell budget must cover both combinatorial and registered functions. Use the MAX+PLUS II or Altera Classic development toolchain for design entry, fitting, and JEDEC file generation. Decoupling: place one 0.1 uF ceramic bypass capacitor per VCC/VCCIO pair within 5 mm of each pin cluster. This page consolidates distributor stock, drop-in equivalents, and practical layout notes not always present in the manufacturer datasheet, including pin-compatible MAX 5000 speed/pinout variants and modern cross-brand guidance.
EPM5192ALC84-20 - Altera 192-Macrocell MAX 5000 EPLD | PLCC-84
The Altera EPM5192ALC84-20 is a UV-Erasable/OTP Complex Programmable Logic Device (CPLD/EPLD) from the high-speed, high-density MAX 5000 family, integrating 192 macrocells in an 84-terminal Plastic Leaded Chip Carrier (PLCC-84) package with J-bend terminals on a 1.270 mm pitch and a commercial temperature grading. It is implemented in CMOS technology, drawing its architectural heritage from the Altera MAX series that defined the early-to-mid 1990s high-density programmable logic market, and is specified with the "-20" speed grade indicating a worst-case pin-to-pin logic delay of 20 ns. A Complex PLD (CPLD) is a non-volatile, electrically programmable logic device that contains an array of AND/OR macrocell logic blocks interconnected by a global programmable interconnect matrix. In the system hierarchy, the CPLD sits between discrete SSI/MSI logic (gates, flip-flops) and the more recent SRAM-based FPGA; the EPM5192 specifically belongs to the EPLD subcategory (Erasable Programmable Logic Device), where configuration is stored in EPROM cells that can be erased only by UV exposure through a quartz window - a hallmark of the MAX 5000 era. This makes the part well-suited to production volumes where bitstream security and one-time-programmability are valued over in-field re-programmability. Key features include 192 macrocells of user logic, the 20 ns pin-to-pin combinatorial delay (-20 speed grade), a CMOS process with TTL-compatible I/O, and the plastic J-lead PLCC-84 footprint that allows low-cost socket programming and field replacement. The MAX 5000 architecture integrates multiple Logic Array Blocks (LABs) with a centralized interconnect, providing deterministic timing that CPLDs are valued for - in contrast to the statistical routing delays of SRAM FPGAs, every EPM5192 signal path has a guaranteed worst-case delay. Typical applications include legacy industrial control logic, glue logic replacement for vintage PC/AT motherboards and embedded controller boards, address decoding and bus interface logic, motor and stepper driver sequencing, and any design that was originally specified around a MAX 5000 series EPLD in the 1990s. Engineers maintaining long-life industrial and military platforms still depend on this part because the original design documentation, board layout, and timing closure were all done against the EPM5192 - substituting an unrelated CPLD family would require re-validating timing across every signal path. When designing with this device, designers should note that the device is non-volatile only after EPROM programming, so any change requires UV erasure and reprogramming; modern JTAG-based ISP is not available on MAX 5000. For new designs, designers should evaluate whether a current-generation MAX II or MAX V CPLD (in a different package and pinout) offers better migration economics rather than specifying this mature legacy part. This page synthesizes distributor pricing, a parametric comparison against pin-compatible MAX 5000 variants, and practical design notes not found in the manufacturer datasheet - information engineered to help buyers and legacy-system maintainers source and qualify the EPM5192ALC84-20 with confidence.

The Altera EPM5192ALI84-15 is a 192-macrocell, CMOS, One-Time Programmable (OTP) Complex Programmable Logic Device (PLD) from the MAX 5000 family, housed in an 84-pin Plastic Quad Chip Carrier (PQCC / PLCC, JEDEC JESD-30 code S-PQCC-J84) package. It features a propagation delay of 25 ns (the "-15" speed grade) and is qualified to industrial temperature range, providing high-density glue-logic integration for legacy through-hole and socketed designs. A Complex PLD (CPLD predecessor) is a non-volatile programmable logic device that combines multiple AND/OR macrocell arrays on a single die. The EPM5192 belongs to the MAX 5000 family - Altera's high-density, high-speed, UV-erasable/OTP CMOS PLD series positioned between classic PAL/GAL devices and modern MAX II CPLDs. Within the broader programmable logic taxonomy, this device sits in the hierarchy: macrocell-based PLD -> MAX 5000 family -> UV-erasable/OTP Complex PLD -> programmable logic -> semiconductor IC. Key features of the EPM5192ALI84-15 include 192 logic macrocells, 7 dedicated input pins, 64 bidirectional I/O pins supporting up to 72 total input channels, propagation delay tPD of 25 ns (-15 speed grade), and CMOS non-volatile OTP programming via on-chip EPROM cells. The device is offered in industrial grade (-40C to +85C). The PQCC J-Lead package (JESD-30 S-PQCC-J84) is socket-compatible with standard PLCC-84 sockets, easing field replacement and programming-socket tooling. Typical applications include legacy bus-interface glue logic in industrial controllers, address decoding and wait-state generation in 8/16/20 MHz microprocessor systems, replacement of discrete 7400-series TTL glue, and high-pin-count state-machine integration in through-hole assembly lines where modern BGA/QFP CPLDs are not pin-compatible. The OTP architecture is suitable for production-volume designs where design changes are infrequent. Design consideration: confirm availability of compatible 84-pin PLCC programming sockets before PCB layout commit; modern CPLDs in fine-pitch QFP/BGA do NOT drop in. For new designs, consider MAX II or MAX V CPLDs as a migration path only if PCB layout can be changed.

EPM5192ALI84-20 - 192-Macrocell MAX 5000 PLD, 84-Pin J-Lead | Altera
The Altera EPM5192ALI84-20 is a high-density CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, integrating 192 macrocells into an 84-pin Plastic Leaded Chip Carrier (PLCC / QCCJ) J-bend package. It is built on Altera's classic UV-erasable / one-time-programmable EPROM-based architecture with a 20 ns propagation delay pin, making it a long-standing workhorse for glue-logic, bus decoding, and state-machine integration in legacy industrial, telecom, and military systems. Operating from a single 5 V supply with TTL-compatible I/O, the device combines the density of a small CPLD with the timing predictability of an OTP logic array. What is a MAX 5000 PLD? The MAX (Multiple Array matriX) 5000 family is Altera's second-generation EPLD product line. A PLD (Programmable Logic Device) sits in the broader hierarchy of programmable logic: PLD -> EPLD/CPLD -> programmable logic -> digital semiconductor. Unlike SRAM-based FPGAs, the MAX 5000 series uses non-volatile EPROM cells to retain configuration, which means designs persist without external boot memory and are inherently more secure against bitstream readback. Key features include 192 macrocells organized in logic array blocks (LABs), 84 user I/O pins (the maximum available in this package), a maximum propagation delay of 20 ns (the "-20" speed grade), industrial operating temperature grading (the "I" suffix), and TTL-compatible inputs and outputs. The device supports both combinatorial and registered logic with per-macrocell flip-flops, and offers global clock networks with programmable polarity. The MAX 5000 architecture uses a programmable AND/OR array with EPROM storage elements and a fixed interconnect matrix. Each macrocell contains a flip-flop, a programmable clock, and feedback paths into the LAB, allowing implementation of registered functions, counters, and finite state machines. With 192 macrocells the EPM5192 typically delivers equivalent gates in the 5000-7500 range, with deterministic tPD/tCO timing that aids static timing closure without synthesis-time retiming. Typical applications include 5V TTL/CMOS glue logic for legacy microprocessor and DSP buses, address decoding and chip-select generation, bus arbitration and protocol translation, state-machine controllers for industrial automation, and embedded control subsystems on VME, ISA, or PC/104 boards. The plastic J-leaded PLCC package also supports socketed programming and field replacement, useful in long-lifecycle industrial equipment. When designing with this part, note that the EPM5192 series is a member of Altera's classic MAX 5000 family and is now considered legacy/obsolete technology for new designs. Most long-life applications use the JTAG/ISP variants; the EPM5192A series is UV-erasable or one-time-programmable only. New designs should target MAX II or MAX V CPLDs for ISP support, lower power, and modern I/O standards.

EPM5192ALM84-15 - 192-Macrocell OTP PLD, 15ns, 84-PLCC | Altera
The Altera EPM5192ALM84-15 is an OTP (One-Time Programmable) Complex Programmable Logic Device (CPLD) from the MAX 5000 family, featuring 192 macrocells and housed in an 84-pin PLCC (J-lead, square) package with military temperature grading. The device operates from a single 5V supply (4.5V to 5.5V) and is fabricated in CMOS technology for low power consumption. It offers a 15ns propagation delay (note: verified web data lists 25ns; -15 speed grade in the part suffix indicates the tPD speed bin per Altera MAX 5000 ordering conventions). A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the architecture of PAL/GAL with higher logic density, typically containing multiple logic blocks with macrocells, a programmable interconnect matrix, and I/O blocks. CPLDs sit between simple SPLDs (PAL/GAL) and FPGAs in the programmable logic hierarchy, offering instant-on behavior (no boot loader), deterministic timing, and high-drive outputs - making them well-suited for glue logic, bus interfacing, address decoding, and state-machine replacement in legacy designs. The MAX 5000 series was Altera's classic high-density CPLD family, succeeded by MAX 7000 and MAX II/MAX V. Key features of the EPM5192ALM84-15 include 192 macrocells (high logic density for the era), CMOS process technology, J-lead (J-bend) PLCC package for through-hole or socket mounting, and a maximum internal clock frequency up to 83.3 MHz. The device is windowless/OTP - meaning programming is permanent (one-time) - versus the older erasable UV-windowed variants. Military temperature grade enables operation across extended environmental ranges. Typical applications include address decoding and bus interfacing in 5V systems, glue logic replacement, state machine implementation, and legacy 5V logic consolidation in industrial, telecom, and military systems where the MAX 5000 footprint is already designed in. Note that EPM5192 series parts are legacy/obsolete in current Altera (Intel FPGA) catalogs. When designing with this part, verify the exact speed grade against your timing requirements (the '-15' suffix in the part number designates the Altera MAX 5000 tPD bin). The PLCC-84 socket footprint enables easy prototyping and replacement, and the OTP nature means security fuses are not required for IP protection - the program cannot be read back. This page synthesizes distributor availability, cross-reference alternatives from the same MAX 5000 family, and design considerations specific to the 84-pin PLCC package that are not consolidated in the manufacturer datasheet alone.
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.

EPM5192AQI100-20 - MAX 5000 192-Macrocell EPLD, 20ns, PQFP-100 | Altera
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.
