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. This page synthesizes distributor pricing, pin-compatible MAX 5000 family alternatives, and practical migration notes not consolidated in any single legacy datasheet, helping engineers source and qualify obsolete Altera EPLDs.
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. The 5 V TTL-compatible I/O simplifies interface to legacy logic but requires bus-termination discipline to avoid undershoot on long traces. This page synthesizes Altera MAX 5000 datasheet specifications, drop-in same-family alternatives, ceramic-package design considerations, and a parametric comparison versus the EPM5192A pin-compatible variants not typically collected in a single place on the manufacturer datasheet.
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.
EPM5192ALI84-15 - 192-Macrocell OTP PLD, 84-PQCC | Altera
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. This page synthesizes EPM5192ALI84-15 distributor availability, package/die siblings, and field-replacement guidance not consolidated on the manufacturer datasheet.
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. This page synthesizes distributor availability, package-level drop-in alternatives from Altera's MAX 5000 family, and practical design notes for long-life maintenance scenarios not found in the original Altera datasheet.
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.

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.

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.

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 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 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.
