EPM5192LC-M205A - 192-Macrocell MAX 5000 CPLD | Altera
The Altera EPM5192LC-M205A is a 192-macrocell CMOS Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, offering 7 dedicated inputs, 64 I/O lines, and 55 ns propagation delay at 5V core supply in a 205-pin package. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic device that combines multiple PAL-like macrocell blocks interconnected by a programmable interconnect array (PIA). CPLDs sit between simple SPLDs and larger FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA -> SoC. They are valued for deterministic timing, low power, and BOM-level glue-logic integration. Key features of the EPM5192LC-M205A include 192 macrocells organized into 12 Logic Array Blocks (LABs), a 55 ns pin-to-pin propagation delay (tPD), and a 5V VCC supply with UV-erasable / one-time-programmable (OTP) configuration memory. The shared input/clock architecture routes one global clock plus seven dedicated inputs to all LABs, and the PIA provides uniform interconnect delays that simplify static-timing closure. Architecturally, the device implements Altera's classic MAX 5000 EEPROM-based macrocell: each macrocell contains a programmable AND/OR array, a flip-flop, and an output enable, fed by 36 product terms. The CMOS EPROM technology yields zero standby current once programmed, and the 205-pin package provides ample I/O for bus- and control-plane integration. Typical applications include legacy industrial control glue logic, address decoding in 5V VME/PCI systems, bus-interface bridging, and state-machine replacement in long-lifecycle aerospace/defense platforms. The 5V tolerance and OTP memory make it well suited to designs that cannot tolerate SRAM-FPGA configuration time. When designing with this device, ensure the 5V supply is well decoupled and that the JTAG/ISP programming interface is brought out to a header. Because OTP variants cannot be re-programmed, keep one socketed unit for prototyping revisions. This page synthesizes distributor pricing, same-package alternatives, and practical design notes not found in the original Altera MAX 5000 datasheet, helping engineers assess migration paths.
EPM5192LC1 - 192-Macrocell MAX 5000 CPLD, 5V, PQCC-84 | Altera
The Altera EPM5192LC1 is a 192-macrocell, 64-I/O, UV-erasable/OTP Complex Programmable Logic Device (CPLD) from the MAX 5000 family, housed in an 84-terminal Plastic Leaded Chip Carrier (PQCC84 / JEDEC S-PQCC-J84) package. The device is built on a 5V CMOS process and operates from a nominal 5V supply with a permitted range of 4.75 V to 5.25 V. The EPM5192LC1 integrates 192 macrocells, 7 dedicated inputs, and 64 I/O pins, and is characterized for a maximum clock frequency of 50 MHz and a pin-to-pin propagation delay (tPD) of 40 ns. The die offers 3.75K equivalent gates of logic capacity. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic IC that sits between discrete logic (PAL/GAL) and FPGAs in the programmable logic taxonomy. CPLDs use EPROM/EEPROM/Flash configuration memory, boot in microseconds, deliver deterministic timing through a predictable AND/OR macrocell fabric, and are typically chosen for glue logic, bus decoding, state machines, and address mapping rather than high-register-count DSP or pipeline work. The MAX 5000 family is Altera's classic second-generation CPLD line, now classified as a legacy/obsolete family maintained primarily for long-lifecycle industrial and military refresh programs. The EPM5192LC1 distinguishes itself through its seven dedicated high-fan-in input pins, which simplify the routing of asynchronous control signals such as reset, clock, and chip-select nets into the AND array without consuming macrocell resources. The 192-macrocell count is among the largest in the MAX 5000 generation, enabling wider and deeper state machines than the smaller 32-, 64-, or 128-macrocell siblings. Designers select the LC1 suffix when the design requires commercial-temperature operation (0°C to 70°C) at the standard speed grade. The device uses a CMOS EPROM cell to retain the user's logic pattern and is one-time-programmable (OTP) in the LC plastic package variant, since the opaque plastic body does not permit UV erasure; an equivalent windowed ceramic (JC) variant supports UV erase and reprogram during development. Programming is performed through the Altera MAX+PLUS II or Quartus (legacy) design flow using industry-standard HDL entry and JTAG-style programming of the EPROM array. Typical applications include industrial 5V backplane glue logic, address decoding for legacy 8086/68000/Motorola microprocessor buses, asynchronous state machines in telecom and instrumentation front-ends, peripheral interface adapters (e.g., GPIB byte-control logic), and refresh/replacement of end-of-life MAX 5000 designs in long-lifecycle programs where pin-compatibility with the original PQCC84 footprint is mandatory. When designing with the EPM5192LC1, observe that 5V tolerance of I/O pins matches the legacy TTL logic levels, that unused macrocells must be terminated per datasheet guidance to avoid crowbar current, and that decoupling requires at least one 0.1 µF ceramic capacitor per VCC/GND pair placed within 5 mm of the package leads. This page consolidates distributor stock, drop-in same-family Altera alternatives in the same PQCC84 footprint, and design notes not aggregated in the original MAX 5000 datasheet.
EPM5192LC2 - 192-Macrocell MAX 5000 EPLD, PQCC-84 | Intel / Altera
The Intel / Altera EPM5192LC2 is a high-speed, high-density EPLD from the legacy MAX 5000 family, delivering 192 macrocells and 64 user I/O lines in an 84-pin PQCC (J-lead ceramic chip carrier) package. Built on a 5V CMOS process, this erasable programmable logic device offers a typical propagation delay of 45 ns (LC-2 speed grade) and supports a maximum clock frequency up to 50 MHz, making it suitable for glue-logic and state-machine integration in legacy industrial systems. The architecture is organized as 12 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), with 7 dedicated inputs (including one external clock input) for synchronous design entry. An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that combines the non-volatility of EPROM storage with combinational and sequential logic resources. EPLDs sit in the broader taxonomy of programmable logic -> CPLD (Complex Programmable Logic Device) -> high-density erasable device -> semiconductor, and are typically used as control-path glue logic, peripheral decoders, and bus-interface bridges between microprocessors and peripheral ICs. Key features include 192 macrocells with shared input/clock architecture, 64 bidirectional I/O pins, 5V VCC operation, erasable windowed package for prototype reprogramming, and JTAG-style boundary-scan capability typical of MAX-series devices. The LC2 suffix denotes a commercial temperature grade with a 45 ns pin-to-pin propagation delay, the slowest speed grade of the family. Architecturally, the PIA fabric routes any LAB output to any other LAB input, providing full connectivity without the routing bottlenecks of older PAL/GAL architectures. Macrocells include product-term arrays with expandable OR planes for wide fan-in logic, plus flip-flops for registered outputs. This dense logic structure was the workhorse of mid-1990s glue-logic design before FPGAs displaced CPLDs in mainstream applications. Typical applications include industrial control boards, telecommunications interface cards, legacy computer backplane glue logic, and military/aerospace systems requiring windowed-erasable reprogrammability. Designers transitioning legacy MAX 5000 designs to newer CPLD families will value the EPM5192LC2 as a known-quantity logic resource. Designers should note that the MAX 5000 family is end-of-life and no longer recommended for new designs. Stock is available primarily through authorized distributors and the secondary market. New designs should target MAX II, MAX V, or MAX 10 CPLD families for active long-term support. This page consolidates distributor pricing, drop-in alternatives from the same MAX 5000 family, and practical design notes that go beyond the manufacturer datasheet's parametric tables.
EPM5192LC84 - 192-Cell OTP PLD, 55ns, LCC-84 | Altera / Cypress
The Altera (now Intel/Altera, also resold as Cypress) EPM5192LC84 is a high-density, UV-1, OTP (One-Time Programmable) CMOS Complex Programmable Logic Device (CPLD) from the classic MAX 5000 family, packaged in an 84-pin LCC (PQCC84 / MS-018) ceramic-compatible plastic carrier. According to distributor and datasheet summaries, it integrates 192 logic macrocells, supports propagation delays around 55 ns, and is built on a CMOS process designed for high-speed glue-logic, bus decoding, and state-machine integration. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines the architecture of a PAL/GAL with on-chip EEPROM/EPROM/flash configuration memory. It sits in the programmable-logic hierarchy between simple SPLDs (PAL/GAL) and FPGAs. CPLDs offer deterministic timing, instant-on configuration, and high drive strength, making them ideal for bus interfacing, address decoding, and control logic. The MAX 5000 family is one of the earliest Altera CPLD generations, predating the MAX 7000/MAX II/MAX V lines, and is now classified as mature/last-time-buy across most channels. Key features of the EPM5192LC84 include 192 macrocells, 55 ns pin-to-pin propagation delay (tPD), CMOS low-power operation, and a generous 84-pin LCC footprint that exposes all user I/O for full utilization. The device is JTAG-configurable via Altera legacy programming tools (MAX+PLUS II baseline), supports multiple I/O standards of its era, and provides programmable macrocell flip-flops with separate set/reset and clock options. Technically, the MAX 5000 architecture uses a classic AND-OR programmable array feeding a flexible macrocell register. The 192-cell count equates to roughly 48 logic array blocks (LABs) in the MAX 5000 taxonomy. The 84-pin LCC package delivers robust thermal and mechanical performance for industrial and legacy military/avionics sockets. Because the device is OTP (or one-time-UV-erasable depending on variant), firmware is committed during manufacture or via windowed UV erasure in development. Typical applications include address/control bus decoding in 8086/68000-era microprocessor systems, glue logic replacement of multiple 74LS/74F TTL packages, industrial machine control boards, and legacy telecom backplane interfacing. The instant-on nature of the non-volatile configuration makes it well-suited to deterministic boot sequences where FPGAs would otherwise require external PROMs. When designing with this part, verify the programming algorithm in MAX+PLUS II legacy mode and confirm second-source availability through Altera/Intel distribution. The LCC-84 socket footprint requires through-hole or socketed mounting; PCB land pattern should match JEDEC MS-018 PQCC84. For new designs, evaluate MAX V (5M240Z) or MAX II (EPM240) as modern, in-production equivalents with similar macrocell counts and lower power.
EPM5192LC84-1 - 192-Macrocell MAX 5000 EPLD, UV-OTP | Altera
The Intel / Altera EPM5192LC84-1 is a 192-macrocell UV-erasable / one-time-programmable Complex Programmable Logic Device (EPLD) from the MAX 5000 family, supplied in an 84-pin PLCC package. It combines high density with high-speed CMOS EEPROM-based logic and is intended for glue-logic, bus-interface, and state-machine replacement in legacy industrial designs. A Complex PLD (CPLD/EPLD) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays with a programmable interconnect matrix, providing greater logic capacity than classic 22V10-style SPLDs while preserving deterministic timing. Within the broader semiconductor taxonomy, the EPM5192LC84-1 sits in the chain: macrocell array -> EPLD -> CPLD family -> programmable logic device -> logic IC -> semiconductor. The MAX 5000 family was Altera's second-generation high-density EPLD line, predating the later MAX 7000/MAX II architectures and using UV-erasable EPROM cells rather than the in-system reprogrammable EEPROM cells of later MAX parts. Key features of the EPM5192LC84-1 include 192 macrocells organized into 16 Logic Array Blocks (LABs), 7,500 usable gates, propagation delays in the 15-25 ns range, and a 100% generic-EE-testable logic architecture with PCI-compliant I/O. The -1 speed grade indicates one of the fastest commercial grades in this family. The 84-pin PLCC (J-lead) package provides through-hole-style footprint compatibility with surface-mount reflow assembly and offers pin counts sufficient for wide bus and control interfaces. Architecture-wise, the device uses an EPROM-based programmable AND array feeding an OR/registered macrocell, with each macrocell offering flip-flop, feedback, and tri-state I/O control. The MAX 5000 family is well known for predictable, deterministic timing because the AND-OR paths have fixed delays independent of routing complexity, simplifying static timing analysis compared to FPGA fabrics. Typical applications include industrial control glue logic, address decoding and bus arbitration in legacy VME/ISA/PCI platforms, peripheral-interface controllers, and pin-compatible replacement for vintage Altera designs. Engineers commonly select the EPM5192LC84-1 when sustaining or repairing long-life-cycle equipment where MAX 7000 or MAX II footprints are not acceptable. When designing with this device, plan for a UV-erasable programming flow or use an OTP (one-time-programmable) adapter window; modern programmers must support the legacy JEDEC fuse-map format used by MAX 5000. Ensure your design budget accommodates the 15-25 ns tPD rather than assuming modern CPLD-class 5-7 ns speeds.

EPM5192LC84-2 - MAX 5000 CPLD 192 Macrocells 84-PLCC | Altera
The Altera EPM5192LC84-2 is a member of the classic MAX 5000 family of high-speed, high-density CMOS EPLDs (Erasable Programmable Logic Devices) housed in an 84-pin PLCC package. It provides 192 macrocells and is specified for commercial temperature operation with the speed grade suffix "-2", which denotes Altera's second-tier propagation delay rating for this die. The device is targeted at glue-logic, bus-interface, and state-machine consolidation applications that previously required multiple TTL/CMOS packages. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-rewritable digital IC that integrates AND/OR array logic, macrocell registers, and a programmable interconnect network onto a single die. The MAX 5000 family sits in Altera's taxonomy as a second-generation EPLD, sitting above simple PAL/GAL devices and below modern MAX II / MAX V non-volatile CPLDs. CPLDs offer deterministic propagation delay (independent of logic path), which makes them ideal for asynchronous interface bridging and bus decode logic where FPGAs' variable delay would be problematic. Key features of the EPM5192LC84-2 include 192 macrocells, a tPD (pin-to-pin propagation delay) defined by the speed grade suffix, programmable output polarity, and a JTAG-compatible or vendor-specific programming interface. The 84-pin PLCC (Plastic Leaded Chip Carrier) package is JEDEC-standardized and supports manual prototyping as well as volume surface-mount assembly. The device operates from a single 5V supply and consumes zero standby current when configured but unclocked. The EPM5192LC84-2 is built on a UV-erasable CMOS process (Altera denoted the OTP variant without the window as LC, while JEDEC ceramic-windowed versions were offered for development). The architecture combines a programmable AND array feeding a fixed OR array with each macrocell containing a flip-flop, output enable, and programmable polarity. Programming is performed via Altera's legacy programming hardware using a JEDEC-standard bitstream. Typical applications include 5V TTL glue logic replacement, microprogram sequencers, state-machine controllers, bus-address decoding, and legacy system upgrades where modern FPGAs would over-engineer the solution. Because the MAX 5000 family is from the early-1990s product generation, it is most commonly found in long-lifecycle industrial, military, and test-equipment designs that have been qualified for decades. Designers should note that the MAX 5000 family lacks modern features such as in-system programmability, hot-socketing, or 3.3V I/O tolerance - it is strictly a 5V TTL-compatible device. The "-2" speed grade is the slowest commercial tier; for higher speed, designers should consult the EPM5192GM/883B (military) variants or move to a MAX 7000/MAX 3000 family device. This page synthesizes XAIPART availability, parametric proximity to same-family variants, and practical design notes that are not duplicated in the original Altera datasheet or third-party distributor listings.
EPM5192LI - 192-Macrocell MAX 5000 CPLD 40MHz 5V | Altera
The Altera EPM5192LI is a high-density UV-erasable / OTP Complex Programmable Logic Device (CPLD) from the legacy MAX 5000 family, integrating 192 macrocells and approximately 3,750 usable gates in a CMOS architecture. It operates from a single 4.5V to 5.5V supply, supports a maximum toggle frequency of 40 MHz, and is housed in an 84-pin Plastic Leaded Chip Carrier (PQCC, package code J84) for surface-mount assembly. A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL/GAL-like macrocell arrays with a central interconnect matrix, providing deterministic timing, low power, and instant-on behavior. CPLDs sit in the programmable-logic hierarchy between small SPLDs (PAL/GAL) and large FPGAs, and are typically used for glue logic, bus decoding, address mapping, and control-state machines where predictable propagation delay is critical. Key features of the EPM5192LI include 192 macrocells organized into 12 interconnected Logic Array Blocks (LABs), 7 dedicated inputs, 72 total inputs, and 64 user I/O lines. The device offers a propagation delay of 55 ns and is built on a CMOS process with EPROM (UV-erasable) non-volatile elements, allowing repeated programming during development. The 'I' suffix denotes the industrial operating-temperature range. Architecturally, the MAX 5000 series uses a programmable AND/OR array with a global interconnect that ties each LAB to the device pins. This produces fixed pin-to-pin timing regardless of how the logic is fitted - a defining advantage over SRAM-based FPGAs for timing-critical control paths. The EPROM cells retain configuration indefinitely with the package window covered, eliminating the need for a separate boot memory. Typical applications include legacy industrial controllers, telecom interface glue logic, military/aerospace systems (in the JM/883 screened variant), and replacement designs for obsolete board-level decode logic. The 84-pin PQCC package offers a JEDEC-standard land pattern that simplifies second-sourcing across vendors. When designing with this device, account for the 55 ns propagation delay in worst-case timing budgets and provide a stable 5V rail with adequate bulk decoupling. For new designs, consider migrating to a MAX II or MAX V CPLD for lower power, faster I/O, and longer-term availability. This page synthesizes distributor stock signals, parametric alternatives, and practical design guidance for the EPM5192LI that goes beyond the legacy datasheet summary.
EPM5192LI-1 - MAX 5000 CPLD, 192 Macrocells, 40MHz, 5V | Altera
The Altera EPM5192LI-1 is a high-speed, high-density CMOS EPLD (Erasable Programmable Logic Device) from the legacy MAX 5000 family, providing 3,750 usable gates organized into 192 macrocells and a maximum toggle frequency of 40 MHz at 5V supply. It is offered in a windowed/UV-erasable ceramic package variant denoted by the JEDEC-style "LI" suffix (ceramic JLCC) and the speed grade "-1". Background: A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic IC that combines the deterministic timing of PAL/GAL architecture with macrocell-based sum-of-products logic. The MAX 5000 family sits between simple PALs and modern FPGAs in the programmable-logic hierarchy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. The "LI" package is a ceramic JLCC (J-Leaded Chip Carrier) suitable for military and industrial temperature grades where hermeticity matters. Key features of the EPM5192LI-1 include 192 macrocells, 3,750 usable gates, 40 MHz worst-case commercial toggle frequency, 5V single-supply operation, 100% tested AC and DC parameters, and a programmable interconnect array (PIA) that routes any macrocell output to any I/O pin. The device is fabricated in 0.7 micron CMOS technology with UV-erasable EPROM cells, allowing multiple design iterations through windowed erasure. It is supported by Altera's legacy MAX+PLUS II development toolchain. The architecture separates I/O from logic via a global PIA, which guarantees predictable, pin-to-pin deterministic propagation delays of approximately 20-25 ns at the -1 speed grade. Each macrocell contains a programmable AND/OR array, a flip-flop with selectable D/T/JK/RS modes, and a configurable output enable. This structure is well-suited to glue-logic, bus-interface, and state-machine applications where predictable timing and instant-on behavior outweigh the absolute gate density. Typical applications include legacy 5V bus-interface bridges, military and avionics replacement programs, factory automation controllers, and printed-circuit-board glue logic for address decoding, interrupt arbitration, and register-based state machines. The ceramic windowed package and industrial/military temperature capability also make it a strong choice for long-lifecycle defense platforms that must match obsolete system-level form factors. Design consideration: the "LI" suffix denotes a ceramic windowed JLCC package with military-grade screening; engineers targeting commercial boards should evaluate the plastic JEDEC variants (e.g., EPM5192LC-1) for cost reasons, while keeping the EPM5192LI-1 reserved for harsh-environment or radiation-tolerant designs. This page synthesizes distributor pricing, verified drop-in same-package alternatives from the Site MPN list, and practical design notes not consolidated in the manufacturer datasheet.
EPM5192LI-2 - 192-Macrocell MAX 5000 PLD | Altera | 84-Pin PLCC
The Altera EPM5192LI-2 is a high-speed, high-density CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, delivering 192 macrocells, 64 I/O lines, and a tpd of 55 ns in an 84-pin PLCC (JEDEC S-PQCC-J84) package. It is the lower-power LI suffix variant and the speed grade -2 derivative of the EPM5192 base device, optimized for industrial temperature operation (-40 C to +85 C) on a 4.5 V to 5.5 V single supply. What is a MAX 5000 device? The Altera MAX (Multiple Array matriX) 5000 series is a classic UV-erasable/OTP Complex Programmable Logic Device (CPLD) family, sitting in the PLD hierarchy between simple PAL/GAL SPLDs and modern SRAM-based FPGAs. Architecturally, a MAX 5000 CPLD partitions logic into interconnected Logic Array Blocks (LABs), each containing a programmable AND/OR array feeding multiple macrocells with configurable flip-flops. Compared to a discrete PAL, a MAX 5000 CPLD provides higher density, predictable timing, and non-volatile (UV-erasable) configuration, while remaining far simpler than an FPGA - no external boot PROM, deterministic pin-to-pin delays, and a unified 5 V supply rail. Key features of the EPM5192LI-2 include 192 macrocells organized into 12 LABs, 72 total inputs (7 dedicated + 64 I/O), 64 user I/O lines, 55 ns pin-to-pin propagation delay, and 100 MHz internal counter frequency. Power consumption is typically 600 mW at 5 V/25 C, and the device supports in-system programming via Altera's MAX+plus II design toolchain. The 84-pin PLCC (J-lead) package offers a socket-compatible upgrade path for legacy designs. From an architectural standpoint, the EPM5192LI-2 uses Altera's classic EEPROM/UV configuration cell with a fast programmable interconnect (PIA) that routes signals between LABs. Each macrocell includes a product-term steering logic block, a programmable flip-flop (D/T/JK), and a user-configurable I/O architecture, giving the designer dense combinational plus registered logic without external glue. The -2 speed grade and the -LI (lower-power, industrial-temperature) suffix make this part well-suited for designs that previously used a 74-series TTL/SPLD combination but now require more logic per board. Typical applications include industrial control glue logic, address decoding in microprocessor/DSP systems, bus interfacing (e.g., ISA, PC/104, VME), state-machine controllers, peripheral replacement, and legacy telecom backplane logic. The 192-macrocell density suits designs that previously required multiple PALs or discrete SSI/MSI logic. When designing with the EPM5192LI-2, engineers should budget the device's worst-case Icc of approximately 600 mW and verify timing with MAX+plus II timing simulation, since the 55 ns tpd directly limits clock frequency at 18 MHz. The 84-pin PLCC package is windowed ceramic or OTP plastic; ensure your programmer supports the EPM5192 JEDEC file format. This page synthesizes distributor pricing, drop-in alternatives from the same MAX 5000 family and the wider Classic PLD ecosystem, and practical design notes that go beyond the manufacturer datasheet's quick-reference tables.
EPM5192LI84 - 192-Macrocell MAX 5000 CPLD 84-PLCC | Altera
The Altera EPM5192LI84 is a UV-Erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, providing 192 macro cells and 3,750 usable gates in an 84-pin Plastic Leaded Chip Carrier (PLCC) package. It operates from a single 5 V supply and supports a pin-to-pin propagation delay of approximately 25 ns, with a maximum toggle frequency of 40 MHz. The LI84 suffix indicates the industrial temperature grade (-40 °C to +85 °C) and the J-lead PLCC J84 package code (QCCJ). A Complex Programmable Logic Device (CPLD) is a non-volatile, flash- or EPROM-based logic device that implements glue logic, state machines, bus decoding, and interface bridging functions between fixed-function ICs. The MAX 5000 family sits within Altera's broader programmable logic hierarchy: CPLD -> Programmable Logic Device (PLD) -> Programmable Logic -> Digital Semiconductor. CPLDs are distinguished from FPGAs by their deterministic timing, instant-on non-volatile configuration, and pin-to-pin delay specifications that do not vary with logic utilization. Key features of the EPM5192LI84 include 192 macro cells, 3.75 K usable gates, 64 user I/O pins, a JTAG-based in-system programming interface (not all variants), and an OTP/UV-erasable configuration memory that retains pattern data without external storage. The PLCC-84 socket-compatible package is removable for laboratory UV erasure and re-programming, which historically made this family attractive for prototyping and low-volume industrial designs. The device uses Altera's classic MAX architecture with an EEPROM/EPROM-based AND plane feeding a fixed OR-plane macro cell fabric. Each macro cell contains a programmable flip-flop, product-term selection logic, and an I/O control block. Logic synthesis is performed with Altera's MAX+PLUS II or Quartus design tools, which are still maintained in legacy mode for industrial customers servicing long-lifecycle equipment. Typical applications include legacy industrial control replacement, military/aerospace avionics refresh (via the JM/883 MIL-STD-883B variants), telecommunications backplane glue logic, and bus-interface bridging in long-lifecycle OEM equipment. The OTP nature makes the EPM5192LI84 suited to designs where the pattern is finalized and re-programming is rarely required. When designing with this part, note that the LI84 device does NOT support in-system programmability - the JTAG port is absent on most MAX 5000 OTP variants, so a stand-alone programmer (e.g. Altera Logic Programmer or compatible third-party tools) is required. Use the LC84 (windowed ceramic) variant if UV erasure is anticipated, and reserve proper decoupling on every VCC/ground pin pair to meet the 5 V TTL I/O switching noise budget. This page synthesizes distributor pricing snapshots, same-brand pin-compatible variants already published on XAIPART (EPM5192LI family members), and practical design notes not found in the legacy Altera datasheet alone.
EPM5192QC-1 - 192-Macrocell MAX 5000 OTP PLD, 40ns, PQFP-100 | Altera
The Altera EPM5192QC-1 is a 192-macrocell high-speed, high-density CMOS Erasable Programmable Logic Device (PLD) from the MAX 5000 family, packaged in a 100-pin PQFP (R-PQFP-G100) with gull-wing terminals and a 0.650 mm lead pitch. The device features a 40 ns propagation delay (tPD) in the -1 speed grade and supports a maximum clock frequency of 50 MHz, making it suitable for glue-logic, bus decoding, and state-machine integration in legacy 5V systems. A Programmable Logic Device (PLD) is a digital integrated circuit whose logic function is configured by the end user after manufacture. Within the broader taxonomy, MAX 5000 devices belong to the One-Time-Programmable (OTP) windowless PLD family, sitting between simple SPLDs and high-density CPLDs/FPGAs in density. They are organized as interconnected Logic Array Blocks (LABs) joined by a Programmable Interconnect Array (PIA), with the EPM5192QC-1 implementing 12 LABs and a shared external clock input feeding all macrocells. Key specifications include 192 macrocells, 64 user I/O lines, 7 dedicated inputs, a 5 V supply range of 4.75 V to 5.25 V, and a -1 speed grade delivering 40 ns pin-to-pin delay. The OTP EPROM-style configuration cell eliminates window erasure and supports surface-mount assembly without quartz erase windows, unlike earlier UV-erasable MAX parts. Architecturally, the EPM5192QC-1 uses a sum-of-products macrocell with a programmable AND/OR plane feeding a configurable output register. Each macrocell supports combinational or registered operation with feedback, and the PIA routes every LAB signal to every other LAB for full connectivity. The shared clock pin and dedicated clock-enable network simplify synchronous design across all 192 flip-flops. Typical applications include 5V microprocessor peripheral decoding, address/data bus arbitration, DMA/state-machine controllers, industrial control glue logic, and legacy telecom backplane glue. The PQFP-100 footprint is widely supported on through-hole adapters for retrofit designs. When designing with this device, ensure that switching noise on the 5 V rail does not exceed the 5.25 V abs-max rating, and use a high-frequency decoupling network (0.1 uF + 10 uF) within 5 mm of every VCC/ground pair to meet tPD specifications under full I/O switching load.

Typical applications include I/O expansion and bridging in industrial controllers, address decoding and glue logic in embedded systems, bus multiplexing for legacy peripherals, power-up sequencing in multi-rail designs, and configuration control for processor subsystems. Its instant-on behavior makes it well suited to deterministic boot paths. When designing with the MAX II CPLD, ensure the Quartus II toolchain is used for synthesis and fitting. Verify pin assignments against the 256-FBGA pinout file and respect MultiVolt bank grouping when mixing 1.8V and 3.3V signals on the same die. This page combines distributor pricing, drop-in pin-compatible alternatives drawn from the same MAX II family, and practical PCB design notes that go beyond what is printed in the manufacturer datasheet.
EPM570F256C5NRR - MAX II CPLD, 570 LEs, 256-BGA | Intel
The Intel (formerly Altera) EPM570F256C5NRR is a non-volatile, low-power MAX II Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements, 440 macro cells, and a 256-ball FineLine BGA (FBGA) package. The 'C5' speed grade delivers 8.7 ns pin-to-pin logic delay (fMAX around 201 MHz internal) while consuming only a few tens of milliamps on a 2.5V/3.3V dual-supply core/IO scheme. It provides instant-on non-volatile configuration via on-chip flash, eliminating external boot memory and shortening power-up latency to microseconds. A CPLD (Complex Programmable Logic Device) is a non-volatile digital IC that combines AND/OR array logic with macro cells, used to implement glue logic, state machines, bus interfaces, and protocol bridges. MAX II sits in the broader hierarchy of programmable logic: PAL/GAL -> SPLD -> CPLD -> FPGA, with CPLDs chosen over FPGAs when designers need fast deterministic pin-to-pin timing, low static power, instant-on configuration, and small-to-moderate logic densities in the 32- to 1,000-LE range. The EPM570 specifically targets designs that need more headroom than entry-level MAX II Z (EPM240) variants while staying below the cost of a low-end FPGA. Key differentiating features include 8.0 Kbytes of user flash memory (UFM) block, support for hot-socketing and JTAG (IEEE 1149.1) boundary-scan, 4 mA IOL drive, in-system programmability via JTAG, and a 0.18 µm flash-based process that allows 100% factory retention of the bitstream across power cycles. The dual-voltage core (2.5 V) and I/O (2.5 V/3.3 V) rails let the device bridge 3.3 V peripherals to 2.5 V controllers without external level shifters on every bus. Architecturally, MAX II uses a Logic Array Block (LAB) topology of 16 macro cells each, interconnected by a FastTrack Continuous Interconnect Matrix (CIM) that delivers predictable ~8 ns timing regardless of placement. The C5 speed grade is the commercial-temperature variant, suitable for 0 °C to +85 °C operation; an 'I' speed-grade variant exists for industrial -40 °C to +100 °C designs. Typical applications include bus-bridging glue logic between a microcontroller and DDR/PCI/USB peripherals, I/O expansion for ASIC/ASSP gaps, power-sequencer and watchdog logic, LED / panel scan controllers, and high-accuracy PWM generation. The BGA-256 footprint suits compact boards where 256-ball density is acceptable; designs requiring hand-solderable packages should consider the EPM570 family members in 100-pin TQFP/256-pin BGA variants. When laying out this device, route the 256 balls on a minimum 1.0 mm pitch and provide four-layer continuous ground/power planes directly under the BGA to minimise VCC bounce. Decouple every VCCIO/VCCINT ball with 100 nF X7R placed within 3 mm of the pad, plus a 10 µF bulk cap per supply rail.

EPM570F256I5 - 570-LE MAX II CPLD, 256-BGA, Industrial | Intel / Altera
The Intel (formerly Altera) EPM570F256I5 is a non-volatile, flash-based MAX II Complex Programmable Logic Device (CPLD) featuring 570 logic elements, 160 user I/O pins, and 8 Kbits of user flash memory, housed in a 256-ball FineLine BGA package. It operates across industrial temperature range (-40C to +85C) with a 3.3V core supply and supports both 3.3V and mixed-voltage 1.5V/1.8V/2.5V/3.3V I/O banks via MultiVolt core and I/O interfaces. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device built from a fabric of Look-Up Tables (LUTs), macrocells, and a programmable interconnect network. In the broader programmable logic taxonomy, CPLDs sit alongside FPGAs as the two dominant families of programmable logic; CPLDs are characterized by deterministic, pin-to-pin propagation delays (typically <10 ns), non-volatile on-chip flash storage, low standby current, and instant-on behavior, making them ideal for glue-logic, bus bridging, I/O expansion, and power-up control tasks where FPGAs are overkill. The MAX II family specifically uses a 0.18 um flash process with a look-up-table based logic array (LE) rather than the older product-term macrocell, giving it higher density per die area while preserving CPLD simplicity. Key features of the EPM570F256I5 include 570 logic elements, 160 maximum user I/Os, 8 Kbits of user flash memory (UFM) usable as general-purpose non-volatile storage, on-chip termination support, JTAG-based in-system programmability (ISP), and MultiVolt I/O that interoperates with 1.5V/1.8V/2.5V/3.3V/5V systems. The device supports I/O standards such as LVTTL, LVCMOS, SSTL, and PCI. Pin-to-pin logic delays in the I5 speed grade are typically in the 5-7 ns range with a maximum clock frequency around 304 MHz (per the MAX II datasheet). From an architecture standpoint, the MAX II family uses a logic-element based fabric divided into Logic Array Blocks (LABs) interconnected by a MultiTrack interconnect; each LE contains a 4-input LUT, a programmable register, and a carry chain, while the UFM block provides 8 Kbits of user-accessible flash that can store boot parameters, serial numbers, or lookup tables without an external EEPROM. The device also includes 4 phase-locked loops (PLLs) for clock synthesis and skew management. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up sequencing and supervisory logic in multi-rail systems, glue-logic replacement for discrete 74-series logic, configuration control for FPGAs and microcontrollers, and protocol translation (UART-to-SPI, I2C-to-parallel) in embedded designs. Its instant-on non-volatile configuration makes it particularly attractive as a companion logic device to ASICs, ASSPs, and microprocessors. When designing with this device, place decoupling capacitors (0.1 uF plus 10 uF bulk) adjacent to each supply pin, follow Intel/Altera Quartus II pin-out guidelines for the F256 BGA (1.0 mm pitch), and connect JTAG TMS/TCK/TDO/TDI to a standard 10-pin header for ISP. Be aware that the MAX II family is now NRND on the Intel product roadmap; for new designs, MAX V or MAX 10 FPGAs are recommended.
