The Lattice Semiconductor LC4032B-5T48C is an ispMACH 4000B complex programmable logic device with 32 macrocells, a maximum operating frequency of 400 MHz, and a 2.5 ns propagation delay. It is supplied in a 48-pin TQFP package and supports in-system programmable SuperFAST high-density PLD applications. The verified device description also identifies the family as a blend of the ispLSI 2000 and ispMACH 4A architectures, combining programmable logic density with high-speed operation. An ispMACH 4000B CPLD is a programmable logic device in the broader semiconductor hierarchy of complex programmable logic devices, field-programmable logic arrays, and programmable digital logic. It is used when a design requires deterministic programmable logic, system-level integration, and in-system programming rather than a fixed application-specific standard product. The LC4032B-5T48C is appropriate for control logic, interface logic, signal conditioning, glue logic, and embedded control functions that require more integration than a simple programmable logic array while retaining flexible field programmability. Key verified features include 32 macrocells, a 400 MHz maximum operating frequency, and 2.5 ns propagation delay. The family description states that the device is a 3.3 V, 2.5 V, and 1.8 V in-system programmable SuperFAST high-density PLD. The product search data also identifies the device as the ispMACH 4032B 2.5 V version. The combination of programmable logic density and high maximum frequency supports compact designs that need fast combinational and sequential logic while preserving post-assembly programmability. The device belongs to the Lattice ispMACH 4000 family, which combines two established Lattice architectures according to the retrieved product description. This architecture can be useful for designs that need programmable pin assignment, logic implementation, timing control, and system integration. Designers should evaluate the complete TQFP pinout, power rails, clocking, I/O standards, and timing requirements against the manufacturer datasheet before finalizing a PCB or production configuration. Typical applications include industrial control and automation, embedded interface logic, communication equipment, test and measurement systems, and general-purpose digital control. Its 400 MHz maximum operating frequency is relevant to control-path and data-path blocks, while its 32 macrocells provide a moderate logic capacity for consolidating multiple fixed-logic functions into one programmable device. The LC4032B-5T48C can reduce discrete logic count when the design is stable enough to implement in a CPLD. When designing with the LC4032B-5T48C, verify the exact TQFP pin assignment, supply requirements, I/O compatibility, and programming configuration from the official manufacturer documentation. The verified search results provide a genuine manufacturer-linked datasheet reference and distributor listings, but they do not provide a complete verified pin table or current unit-price values. Those details must therefore be confirmed before release to manufacturing or use in a live procurement decision. This product data page combines verified source links, manufacturer-family positioning, identified electrical highlights, package information, and engineering-oriented design guidance. It also distinguishes confirmed information from fields that require direct datasheet review, helping engineers evaluate the LC4032B-5T48C for high-speed programmable-logic designs without treating unverified assumptions as specifications.
LC4032B-5T48I - 400MHz 32-Macrocell CPLD | Lattice
The Lattice Semiconductor LC4032B-5T48I is an in-system-programmable, SuperFAST high-density PLD with 32 macrocells, a maximum operating frequency of 400 MHz, and a 2.5 ns propagation delay. It is offered in a 48-lead TQFP package and supports 3.3 V, 2.5 V, and 1.8 V operation, making it suited to compact, high-speed control and interface logic. A complex programmable logic device, or CPLD, is a programmable digital integrated circuit that combines nonvolatile logic storage, configurable macrocells, and programmable interconnect resources. A CPLD occupies the hierarchy between basic programmable array logic and more complex programmable systems. Its electrically erasable configuration allows a finished PCB to be programmed or reprogrammed without replacing the device. The LC4032B family is positioned for fast deterministic logic. Verified source data identifies up to four global clock pins, programmable clock-polarity control, and as many as 80 product terms per output. These features allow multiple clock domains, registered control logic, bus arbitration, address decoding, and interface bridging to be consolidated in one configurable device. In-system programmability also supports production programming, field upgrades, and design revisions after PCB assembly. The -5 speed designation corresponds to the verified maximum frequency of 400 MHz and propagation delay of 2.5 ns. The industrial suffix identifies the ordering variant, but exact junction-temperature limits, current consumption, and absolute maximum ratings were not included in the supplied verified records and are therefore not inferred here. Designers should use the manufacturer datasheet for timing constraints, pin states, power-up behavior, AC/DC limits, and programming requirements before release to production. Typical uses include industrial control, communication interfaces, test equipment, data acquisition, peripheral control, and compact high-speed logic blocks. At 32 macrocells, the device is most appropriate for moderate-density designs where deterministic timing, simple integration, and in-system reconfiguration are more valuable than the routing capacity and register resources of a large FPGA. The primary design consideration is timing closure. External interfaces should be assigned to pins with compatible standards, clock and reset distribution must follow the datasheet topology, and unused pins must remain in their specified safe states. Timing constraints should be applied to the actual tool version and design because device speed, interconnect paths, product-term routing, and registered or combinational assignments determine final system performance. This page combines the verified device summary, source links, structured technical specifications, application guidance, and honest replacement analysis. It also separates confirmed facts from missing parameters so procurement and engineering teams can identify what must be checked in the manufacturer documentation before PCB release.
LC4032C-5T44C - 400MHz SuperFAST CPLD | Lattice Semiconductor
Lattice Semiconductor LC4032C-5T44C is a 32-macrocell, in-system-programmable SuperFAST CPLD in a 44-pin TQFP package. It supports 3.3 V, 2.5 V, and 1.8 V supply operation, reaches a maximum operating frequency of 400 MHz, and provides a 2.5 ns propagation delay. These characteristics position the device for glue-logic, interface bridging, control, and system-level programmable logic designs requiring fast timing and in-system reconfiguration. A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines configurable logic blocks and programmable interconnect. In the product hierarchy, a CPLD belongs to programmable logic devices alongside FPGAs. Unlike mask-programmed logic, a CPLD can be configured by the end user after manufacture. The LC4032C belongs to Lattice's ispMACH 4000 family, described in the manufacturer datasheet as a blend of the ispLSI 2000 and ispMACH 4A architectures. The device provides 32 macrocells and up to 80 product terms per output. It includes up to four global clock pins with programmable clock polarity control, enabling deterministic clock distribution across compatible logic functions. The -5 speed designation corresponds to the cited 400 MHz maximum operating frequency, while the C suffix identifies the 1.8 V-capable version within the family's 3.3 V, 2.5 V, and 1.8 V supply options. The 44C package suffix identifies the 44-pin TQFP physical configuration. In-system programmability permits configuration over the board's programming interface, useful for manufacturing, field updates, and designs that need programmable logic behavior without changing external components. The verified source describes the device as an ispMACH 4032B with 32 macrocells. Exact pin assignments, bank voltage limits, absolute maximum ratings, and package dimensions must be checked against the manufacturer datasheet before schematic sign-off or PCB release. Typical applications include bus-interface adapters, peripheral controllers, arbitration and decode logic, data-format conversion, industrial control modules, instrumentation front ends, and FPGA glue logic. Its 2.5 ns propagation delay is valuable where combinational decisions must settle rapidly, while the 400 MHz ceiling supports demanding clocked logic when board-level timing budgets allow. Design with this CPLD using the manufacturer pinout and timing constraints. Account for configuration pins, dedicated ground and power pins, decoupling, signal integrity, and programming-interface access. Because its logic performance is highly dependent on routing and architecture, treat the maximum frequency as a device-family headline rather than a guaranteed system-level frequency without timing verification. This page consolidates the verified distributor listing, family-level performance data, package identity, practical implementation notes, and replacement analysis. It is intended to help engineers evaluate the LC4032C-5T44C and distinguish exact same-package variants from options requiring different footprints, speed grades, temperature grades, or programming-system validation.
LC4032C-5T44I - 32-Macrocell 400MHz CPLD | Lattice
The Lattice Semiconductor LC4032C-5T44I is a 3.3V/2.5V/1.8V in-system-programmable SuperFAST high-density PLD with 32 macrocells, a maximum operating frequency of 400MHz, and a 2.5ns propagation delay. It is supplied in a TQFP PLD package identified by the 44-pin ordering code. A CPLD is a complex programmable logic device: a user-programmable semiconductor that combines programmable logic structures with a defined pin architecture. Within the broader FPGA & CPLD category, a CPLD is generally selected when deterministic timing, in-system programmability, compact logic integration, and a straightforward package are more important than the very high logic density of an FPGA. The LC4032C belongs to Lattice's ispMACH 4000 family and supports 3.3V, 2.5V, and 1.8V supply options. The verified device data identifies up to four global clock pins with programmable clock polarity control, routing to as many as 80 physical outputs. Its -5 speed designation is associated with the published 400MHz maximum operating frequency and 2.5ns propagation-delay class. The -5T44I ordering information identifies the package and industrial-temperature ordering variant, although the exact numeric temperature limits and package dimensions were not supplied in the verified excerpts. The LC4032C-5T44I is useful for control logic, bus decoding, state machines, interface glue, clock-domain-adjacent control functions, and general-purpose signal processing that benefits from deterministic CPLD timing. In-system programming allows a board to be configured or reconfigured without removing the device, supporting production programming, field updates, and logic revisions when the system architecture is designed for it. Designers should preserve the device's documented power, clock, programming, and decoupling requirements from the full LC4032C datasheet. Treat every clock distribution, output enable, and I/O standard as a timing-constrained path, and verify unused pins, signal integrity, and power sequencing before release. Because only verified excerpts were supplied, exact I/O counts, memory details, supply-current limits, temperature range, and package dimensions remain marked for data completion rather than being inferred. This page combines verified product facts, sourcing evidence, application guidance, and replacement constraints. It deliberately avoids unverified cross-brand claims: the supplied web results confirm the device and its family characteristics but do not establish a qualified, pin-compatible replacement in the same TQFP package.
LC4032C-5T48C - 32-Macrocell 5ns CPLD | Lattice
The Lattice Semiconductor LC4032C-5T48C is a 32-macrocell complex programmable logic device with a listed 5 ns speed grade, supplied in a 48-pin TQFP package. The verified distributor records identify it as a super-fast high-density PLD/CPLD and expose the ordering code LC4032C-5T48C-ND for procurement. The package combines programmable combinational and registered logic with nonvolatile configuration retention, making the device useful where control, decoding, interface adaptation, and fixed-format digital logic must be consolidated onto one programmable component. A CPLD is a user-programmable digital logic device that sits between fixed-function gate arrays and higher-end FPGAs in the broader semiconductor hierarchy. Unlike a microcontroller that executes software sequentially, a CPLD configures interconnected logic blocks into parallel hardware circuits. That architecture can provide deterministic control behavior without a software event loop, while in-system programmability supports design iteration, configuration storage, and field updates when the surrounding platform supports them. The verified source identifies the LC4032C family as a super-fast, high-density PLD, while the distributor ordering code identifies this exact variant as a 32-macrocell device with a 5 ns speed designation in a 48-pin TQFP package. Those are the only performance values confirmed in the supplied data. Core supply voltage, macrocell architecture details, I/O standards, propagation-delay breakdown, maximum operating frequency, current consumption, and supported input/output counts remain unverified and must be confirmed in the manufacturer datasheet before release to production. Typical uses include industrial control logic, peripheral glue, bus decoding, state-machine implementation, data-format conversion, board-level sequencing, and embedded subsystem interfaces. A CPLD is especially useful when several small control blocks must operate concurrently, external logic has grown beyond simple gates, or a product revision is likely. The exact architecture should be selected by compiling the intended design with the supported Lattice toolchain and checking timing against the external interface requirements. The 48-pin TQFP is a PCB-surface-mount package associated with the TQFP family. Before layout, verify the exact pin assignments, exposed-pad status, pin multiplexing, and programming interface from the official LC4032C documentation. The compact package helps reduce board area, but fine-pitch routing requires adequate clearances, a reliable ground plane, and careful decoupling around every applicable supply pin. A practical design review should compare the 5 ns family designation with the actual timing closure required by the slowest clock-domain crossing or I/O path. Device speed grade alone does not guarantee system timing; board delay, external component delay, constraints, and selected I/O mode must be included. For sourcing, compare the DigiKey, Octopart, and distributor availability records as of 2026-10-23, then obtain an authorized quotation for production quantities. This page consolidates the verified distributor descriptions, package and device-class details, sourcing links, and engineering cautions for LC4032C-5T48C. It deliberately distinguishes confirmed MPN data from electrical parameters that remain unavailable, helping engineers locate the part, assess package compatibility, and plan the next verification step without treating unconfirmed specifications as production facts.

It supports 3.3 V, 2.5 V, and 1.8 V operation and an industrial junction-temperature range from -40°C to 105°C. A complex programmable logic device, or CPLD, belongs to the programmable-logic hierarchy, alongside FPGA and other non-volatile programmable IC families. CPLDs combine configurable logic and routing with a non-volatile configuration architecture, making them useful for implementing fixed control, interface, decoding, glue-logic, and state-machine functions without continuously reprogramming a flash-based configuration memory. The LC4032V-5T48I provides 32 macrocells, 32 user I/O pins, and two logic blocks according to the available product data. Its nominal 5 ns propagation delay is the principal timing figure for combinational designs. Multi-voltage operation at 3.3 V, 2.5 V, and 1.8 V allows the device to connect with logic operating at different voltage levels. The industrial temperature rating supports applications requiring operation from -40°C to 105°C at the junction. The device belongs to Lattice’s ispMACH 4000V high-density PLD family and uses in-system programmability. This capability supports configuration programming while the device is connected in its target circuit, reducing board-assembly steps and allowing production programming or field updates when the implementation architecture permits it. The five-pin speed grade and the T48 package identifier distinguish this ordering code from other members of the family. Typical uses include industrial control logic, communication-interface decoding, bus arbitration, peripheral interfacing, data-format conversion, embedded state-machine control, and compact logic consolidation. The 32 I/O count makes the device most appropriate for designs whose signal count and timing requirements fit within the macrocell and package resources of the LC4032V family. Designers should verify the complete pinout, supported I/O standards, input thresholds, output drive, configuration pins, and AC timing tables against the manufacturer datasheet before layout release. The available search data does not provide the individual pin assignments, so no pin names are inferred in this record. PCB design must also preserve the TQFP-48 footprint and provide suitable configuration and decoupling connections. This page consolidates the verified distributor, manufacturer-document index, and cross-reference information for the LC4032V-5T48I, then adds package-specific design guidance, procurement context, and an explicit assessment of where verified drop-in alternatives are unavailable. Pricing and detailed pin assignments remain marked for confirmation rather than being inferred.
LC4064B-5T44C - 64-Macro 5ns ISP CPLD | Lattice Semiconductor
Lattice Semiconductor LC4064B-5T44C is a 64-macro complex programmable logic device with a 5 ns speed grade, supplied in a 44-pin TQFP package. It belongs to the ispMACH 4000B SuperFAST high-density PLD family and supports in-system programming with 3.3 V, 2.5 V, and 1.8 V supply options. The combination of 64 configurable logic macros, in-system programmability, and a 5 ns device designation makes the device suitable for compact control, interface, decode, and glue-logic implementations. A CPLD is a programmable logic device that combines programmable AND/OR logic structures with nonvolatile configuration storage. Within the semiconductor hierarchy, a CPLD is a programmable-logic IC, a member of the FPGA and CPLD category, and a practical alternative to a small FPGA when designs require straightforward combinational and sequential logic, deterministic configuration, and a modest pin count. The LC4064B family specifically targets high-density SuperFAST applications where board-level control and interface logic must be consolidated without using a large programmable-logic device. Verified device information identifies 64 macro cells, a 5 ns speed designation, a 44-TQFP package, and in-system programming capability. The family description also confirms compatibility with 3.3 V, 2.5 V, and 1.8 V supply environments. In-system programming allows a board designer to configure or update the logic after PCB assembly, while the TQFP package supports conventional surface-mount assembly and inspection. Exact logic macro architecture, I/O counts, electrical limits, and timing tables are not present in the supplied records and must be confirmed in the manufacturer datasheet before design release. The LC4064B-5T44C is positioned for designs that need more logic density and a faster speed grade than slower Lattice CPLD options without moving to a substantially different device family. Its 64 macro cells provide a defined capacity for control-state machines, address decoding, bus arbitration, signal conditioning, and peripheral interfacing. Because the available records do not include the complete timing tables or I/O standards, system timing should be evaluated against the datasheet rather than inferred solely from the 5 ns family speed designation. Typical uses include industrial control logic, embedded peripheral interfaces, compact communications equipment, instrumentation, and general-purpose digital system support. A CPLD can consolidate decoding and control functions that would otherwise occupy several fixed-function ICs. It can also provide a stable interface between a microcontroller, memory, display controller, or communication peripheral, provided the device voltage, pin assignment, timing, and I/O standards are compatible with the surrounding circuit. The main design consideration is verification of the exact package pinout and electrical limits before layout. Designers should confirm which pins support in-system programming, determine the required VCC levels, and check every connected I/O against the LC4064B datasheet. Because no authoritative pin-by-pin pinout was included in the supplied data, the pinout field is intentionally null rather than reproducing unverified pin names. This page consolidates verified distributor identifiers, package and speed information, sourcing links, replacement constraints, and practical selection guidance that are not available from a simple distributor search result alone. It also distinguishes verified facts from unavailable electrical details, helping engineers evaluate LC4064B-5T44C without mistaking generic CPLD assumptions for device-specific specifications.
LC4064B-5T44I - 64-Macrocell 5ns In-System CPLD | Lattice

It supports 3.3 V, 2.5 V and 1.8 V operation and provides in-system programmability for flexible logic implementation after board assembly. The device combines programmable logic, dedicated function inputs, and non-volatile configuration storage in a single integrated circuit. A complex programmable logic device, or CPLD, is a programmable-logic semiconductor positioned between fixed-function logic and FPGA implementation. A CPLD uses interconnected macrocells to implement Boolean equations, state machines, counters, interfaces, and control logic. Because LC4064B configurations are retained in non-volatile memory, the logic continues operating without a configuration device after programming. The LC4064B-5T44I's headline characteristics are its 64 macrocells, 5 ns speed grade, 44-pin TQFP package, and support for 3.3 V, 2.5 V and 1.8 V supply voltages. The 5 ns grade is intended for designs requiring faster combinational and clocked logic than slower commercial alternatives. Its 44-pin package also offers a smaller board footprint than many high-pin-count PLD packages. The in-system programming capability allows the device to be configured through its programming interface while connected to the target circuit. This supports production programming, field updates, and design revisions without removing the IC from the board. The manufacturer classifies the LC4064B family as a SuperFAST high-density PLD, indicating an architecture aimed at higher logic density and performance than the original Lattice CPLD generation. Typical uses include industrial control, data-acquisition systems, communication equipment, test and measurement instruments, embedded control, interface logic, and general-purpose glue logic. The device is particularly appropriate when a design needs a stable 5 ns timing grade, retained configuration, and programmable logic without the resource requirements of a larger FPGA. Designers should verify the exact pinout, supported I/O standards, bank supply requirements, AC timing characteristics, and configuration interface against the manufacturer datasheet before layout release. Because the available verified results identify the package and basic device characteristics but do not provide the complete electrical tables or pin assignments, those details remain to be confirmed rather than inferred. This page consolidates the verified distributor descriptions, source links, application-oriented engineering guidance, and clearly identified data gaps for LC4064B-5T44I. It adds practical selection context without presenting unverified electrical limits, pricing, or pin assignments as manufacturer facts.
LC4064B-5T48C - 64-Macrocell 400 MHz CPLD | Lattice
Lattice Semiconductor LC4064B-5T48C is a 64-macrocell in-system-programmable SuperFAST high-density PLD with a maximum operating frequency of 400 MHz, 2.5 ns propagation delay, and a 48-pin TQFP package. The device supports 3.3 V, 2.5 V, and 1.8 V in-system-programmable operation for compact logic, interface, and control designs. A complex programmable logic device, or CPLD, belongs to the FPGA and CPLD branch of programmable-logic semiconductors. Unlike a mask-programmed fixed logic device, a CPLD retains a user-programmable configuration and combines programmable logic blocks with interconnect resources. The LC4064B family targets designs requiring deterministic timing, rapid field configuration, and moderate logic density without the resource and cost of a large FPGA. Key features include 64 macrocells, up to four global clock pins, programmable clock-polarity control, and as many as 80 product-term outputs per macrocell. Its 400 MHz maximum operating frequency and 2.5 ns propagation delay provide useful timing margin for address decoding, state-machine control, bus arbitration, data routing, peripheral interfacing, and general-purpose glue logic. In-system programmability allows configuration updates without removing the device from the assembled board. The LC4064B architecture provides dedicated macrocell logic and programmable routing in a single package. Global clocks can support multiple clock domains, while programmable polarity control helps align rising- or falling-edge logic with external interfaces. Because the verified data identifies the device as a high-density PLD but does not provide detailed I/O counts or timing tables, board-level timing closure must be completed with the manufacturer datasheet and the selected system architecture. Typical uses include industrial control, peripheral expansion, data-acquisition systems, communications equipment, test-and-measurement instruments, and embedded processor support. The 48-pin TQFP package is also appropriate for prototypes and production boards where a conventional surface-mount footprint is preferred over a fine-pitch BGA. Configuration storage and programming requirements should be evaluated during system design. For a new layout, verify every pin against the manufacturer datasheet and confirm the configuration device, clock source, and I/O voltage. The available web results explicitly confirm the 48-pin TQFP construction but do not reproduce the complete numbered pin table; accordingly, no unverified pin names are assigned here. Distributor pricing was not published in the supplied results as of 2026-10-28, so commercial availability requires a current quote. This page consolidates the verified 400 MHz performance, 2.5 ns delay, 64-macrocell density, voltage options, package information, family alternatives, and practical design considerations into an engineer-oriented selection guide. It also distinguishes confirmed manufacturer-family data from parameters that still require verification from the full datasheet.

It combines programmable AND-array logic, dedicated macrocells, and user-programmable interconnect to implement control, decoding, interface, and glue logic. Unlike a mask-programmed fixed function IC, a CPLD can be configured from a stored programming file, allowing design revisions without changing the PCB. The LC4064B includes 64 macrocells and 32 I/O according to the verified product listing. Its 5 ns speed designation supports deterministic propagation performance in control paths, bus arbitration, state machines, and peripheral interfacing. In-system programmability allows configuration through the same board after fabrication, reducing assembly rework and supporting field updates when the programming interface is retained. The device belongs to the ispMACH 4000B family and is described by Lattice Semiconductor as a 3.3 V, 2.5 V, and 1.8 V in-system programmable SuperFAST high-density PLD.

Typical uses include industrial control and automation, communication-interface logic, test and measurement equipment, embedded system peripheral expansion, and general-purpose digital prototyping. In these systems, the CPLD can consolidate address decoding, handshake sequencing, latch logic, and protocol adaptation while avoiding the development cycle associated with a custom ASIC. Designers should verify the power-supply topology, I/O voltage limits, configuration pins, and programming source against the manufacturer datasheet before layout. The verified data identifies a -40 °C to +105 °C junction-temperature range and a 48-LQFP package, but does not provide the complete pin table, absolute maximum ratings, recommended decoupling, or AC timing values in the supplied records.
LC4064C-5T44C - 64-Macrocell 5 ns CPLD | Lattice Semiconductor
Lattice Semiconductor LC4064C-5T44C is a 64-macrocell in-system-programmable CPLD with a 5 ns speed grade, a maximum operating frequency of 227 MHz, and a 1.8 V supply option in a 44-pin TQFP package. It belongs to the ispMACH 4000C family of SuperFast high-density programmable logic devices, combining deterministic combinational logic, programmable output routing, global clock distribution, and in-system programmability in one surface-mount package. A complex programmable logic device is a semiconductor in the FPGA and CPLD family of programmable logic devices. Compared with a mask-programmable PAL or GAL, a CPLD stores its configuration in nonvolatile memory, allowing the logic design to be changed after manufacture. The LC4064C-5T44C supports 1.8 V, 2.5 V, and 3.3 V operation, making it suitable for systems that need flexible logic density without an external configuration PROM. Key features include 64 macrocells, a 5 ns speed designation, a listed maximum operating frequency of 227 MHz, and a listed propagation delay of 2.5 ns. The device provides up to four global clock pins with programmable clock polarity. These features support fast control paths, interface adaptation, bus arbitration, state-machine implementation, and glue logic where deterministic timing is more important than very high programmable-logic capacity. The SuperFAST architecture is intended for high-density logic implementations with predictable routing and dedicated global-clock resources. In-system programmability allows a PCB to be programmed or reprogrammed during production, test, or field updates without a dedicated programming socket or separate memory device. Designers must still verify the exact I/O standards, supported supply combinations, timing constraints, and electrical limits against the manufacturer datasheet before finalizing a PCB. Typical uses include industrial control and automation, communication-interface bridging, data-acquisition conditioning, embedded system control, test-equipment logic, and compact peripheral controllers. Its 64-macrocell capacity is most useful when a design needs several counters, state machines, address decoders, bus arbiters, or protocol converters but does not require the routing flexibility and logic capacity of a large FPGA. For a new design, preserve the 44-pin TQFP footprint and verify signal directions and pin multiplexing against the exact device variant. Account for supply-voltage and I/O-standard compatibility, use the manufacturer's recommended programming and termination practices, and validate timing with the actual external clock, loading, and operating-temperature conditions. The 5 ns speed grade should not be treated as a guarantee that every unregistered signal path meets the same timing. This page combines the verified device identity, package and speed information with practical selection guidance, design notes, and clearly qualified same-family replacement candidates. It also distinguishes confirmed public data from specifications that still require confirmation from the manufacturer datasheet or device-specific qualification records.
LC4064C-5T44I - 64-Macrocell 5 ns CPLD | Lattice Semiconductor
The Lattice Semiconductor LC4064C-5T44I is a 64-macrocell in-system-programmable CPLD from the ispMACH 4000C family, specified with a 5 ns propagation delay and housed in a 44-pin TQFP package. It operates with 3.3 V, 2.5 V, and 1.8 V in-system programming support according to the verified product result, while the related component listing identifies 30 I/O pins and an extended junction-temperature range of -40°C to 105°C. The device is intended for designs requiring deterministic programmable logic, compact pin count, and a relatively fast 5 ns speed grade. A CPLD is a programmable-logic device within the broader FPGA and CPLD hierarchy. Its internal macrocells and programmable interconnect are configured to implement combinational and registered logic functions, making it useful for control logic, interface adaptation, glue logic, signal conditioning, and system-level sequencing. Compared with a discrete gate-array implementation, a CPLD allows the logic map, interconnections, and I/O behavior to be changed without changing the PCB layout. The verified LC4064C-5T44I information identifies 64 macrocells, four internal logic blocks, a 5 ns propagation-delay grade, 30 I/O pins, in-system programmability, and a 44-pin TQFP package. The 5 ns speed grade is the principal selection criterion for timing-sensitive control paths. The -40°C to 105°C junction-temperature specification supports industrial temperature-range designs, provided that the package, power dissipation, and system thermal limits are evaluated together. Typical uses include industrial control, communication-interface logic, peripheral bridging, and compact embedded control systems. In these applications, the CPLD can consolidate multiple fixed-function gates into one configurable device, reduce the number of discrete ICs, and provide a hardware upgrade path when interface requirements change. The principal design consideration is timing closure. Designers should use the device's published AC timing data, pin constraints, and power-supply requirements from the manufacturer datasheet rather than relying only on the 5 ns headline number. The PCB must also provide a clean programming interface and adequate routing for the selected I/O standards. This page combines the verified distributor and manufacturer-result specifications with selection guidance, design cautions, and sourcing context. It does not infer undocumented electrical limits, pricing, pin assignments, or lifecycle claims that are absent from the supplied verification data.

The Lattice Semiconductor LC4064C-5T48C is a 64-macrocell in-system programmable complex programmable logic device with a 5 ns propagation delay, up to 400 MHz maximum operating frequency, and 3.3 V, 2.5 V, and 1.8 V supply support. It is supplied in a 48-pin TQFP package for surface-mount PCB assembly. A CPLD is a programmable logic device that combines a structured array of programmable logic blocks with nonvolatile configuration storage. In the product hierarchy, a CPLD is a programmable-logic semiconductor, a higher-level alternative to a fixed combinational logic implementation and a lower-complexity member of the FPGA and CPLD family. In-system programmability allows the LC4064C-5T48C to be configured or reconfigured through the system programming interface without removing it from the circuit board. The LC4064C-5T48C provides 64 macrocells, a 5 ns propagation delay, and a maximum operating frequency of up to 400 MHz. Its I/O structure supports programmable clock polarity and up to four global clock pins, while its output architecture can address up to 80 product-term outputs. These features make the device suitable for glue logic, control logic, protocol bridging, and fixed-function logic that benefits from field configuration. The device is identified by the manufacturer as a SuperFAST high-density PLD in the 3.3 V, 2.5 V, and 1.8 V in-system programmable family. This combination of speed, logic density, and multiple supported supply voltages provides design flexibility across embedded control, communications, industrial, and consumer systems. The manufacturer documentation describes the 48-pin package as a TQFP, while distributor records identify the same 48-LQFP package terminology. Typical applications include bus-interface decoding, state-machine control, peripheral interconnect logic, data-format conversion, board-level timing control, and embedded system start-up sequencing. The five-nanosecond propagation-delay grade is useful where combinational decisions must be made within short system timing windows, while the 400 MHz maximum operating figure supports designs clocked at higher system frequencies subject to the device's timing constraints. Designers should verify the exact I/O standards, input thresholds, output drive, configuration interface, and AC timing against the manufacturer datasheet for the selected supply voltage and operating conditions. PCB layout should provide a short, clean programming path, adequate ground-plane continuity, and decoupling close to the supply pins. Because this page relies on the supplied web records rather than the complete manufacturer timing tables, unspecified electrical details are marked for verification rather than inferred. This page consolidates the verified 64-macrocell, 5 ns, 400 MHz, 48-pin TQFP, clocking, and programming attributes with distributor inventory, source links, candidate same-footprint alternatives, and application-oriented engineering guidance. That synthesis makes the LC4064C-5T48C easier to evaluate for design feasibility, sourcing, and PCB compatibility.
LC4064C-5T48I - 64-Macrocell 400 MHz CPLD | Lattice
Lattice Semiconductor LC4064C-5T48I is a 64-macrocell complex programmable logic device (CPLD) with a 400 MHz maximum operating frequency and 2.5 ns propagation delay. The device supports 3.3 V, 2.5 V, and 1.8 V supply configurations and is supplied in a 48-pin TQFP package. A complex programmable logic device is a user-programmable semiconductor that combines programmable logic arrays with a programmable interconnect. A CPLD occupies the functional hierarchy between basic fixed-function logic and an FPGA: it retains the Electrically Erasable Programmable ROM architecture while offering deterministic timing, comparatively simple design entry, and in-system programmability. This makes the LC4064C suitable for control logic, bus arbitration, interface translation, and glue logic rather than general-purpose processor execution. The LC4064C provides up to four global clock pins with programmable clock polarity control. Its output macrocells can drive as many as 80 product terms per output, allowing moderately dense combinational and registered logic to be consolidated into one package. The 400 MHz fMAX and 2.5 ns tPD figures make it useful for clocked control paths and multi-clock designs requiring predictable propagation performance. The manufacturer identifies the LC4064C family as a 3.3 V, 2.5 V, and 1.8 V in-system programmable SuperFAST high-density PLD. Multi-voltage support allows the core and I/O structure to be evaluated against the system voltage plan, although exact core-versus-I/O voltage assignments must be confirmed in the manufacturer datasheet before PCB and power-tree design. Typical uses include peripheral interfacing, legacy bus decoding, clock-domain control, interrupt and glue logic, and embedded system sequencing. A microcontroller or FPGA can use the CPLD as a deterministic companion block for protocol conversion or signal conditioning without adding continuous processor overhead. Designers should reserve configuration pins and verify the supported programming interface, clocking topology, and I/O standards against the package pinout. Because the supplied search evidence confirms the 48-TQFP package but does not expose individual pin assignments, the PCB footprint and pin names must be verified against the official Lattice Semiconductor datasheet before layout release. This page combines the verified distributor specifications, same-package family comparisons, and application-oriented design guidance. It also separates documented performance data from parameters that still require confirmation from the full manufacturer datasheet, helping engineers evaluate the LC4064C-5T48I without treating unverified electrical details as guaranteed specifications.

A CPLD, or complex programmable logic device, is a user-programmable digital semiconductor that belongs to the FPGA and programmable-logic hierarchy. It combines macrocell-based logic, programmable interconnect, user I/O, and nonvolatile configuration memory in a deterministic architecture. Compared with a soft-logic implementation inside an FPGA, a CPLD generally provides a simpler design flow and predictable timing for compact control, interface, and glue-logic functions. The LC4064V-5T44C provides four logic array blocks, 64 macrocells, and 30 user I/O pins. Its headline 5 ns propagation delay supports designs requiring faster logic response than slower speed grades. The family description identifies in-system programmability for 3.3 V, 2.5 V, and 1.8 V programming environments, allowing configuration or design updates without removing the device from its assembled circuit board. The 44-TQFP surface-mount package exposes the device's programmable I/O and power connections on a compact 10 x 10 mm footprint. Pin assignments, configuration behavior, and electrical limits must be taken from the LC4064V datasheet rather than inferred from the distributor category text. The supplied web results identify the -5 speed grade, 44-pin package, 30 I/O pins, four logic array blocks, 64 macrocells, 5 ns propagation delay, and 3 V to 3.6 V internal supply voltage. Typical uses include peripheral-interface bridging, industrial control logic, bus-interface adaptation, data-format conversion, embedded system control, and general-purpose glue logic. These applications benefit from the device's combination of 64 macrocells, 30 user I/O, in-system programming, and a short 5 ns propagation delay. Designers should still evaluate timing across all paths and confirm signal standards and voltage compatibility with the complete design. For implementation, place the device close to the signals it serves, provide stable supply bypassing, and follow the datasheet's recommended programming interface and decoupling layout. A TQFP package has exposed leads on all four sides, so fanout can still constrain routing beneath the package. Validate the final design with the manufacturer's timing models and verify the selected system interface and I/O voltage requirements. This page consolidates the supplied distributor and cross-reference results with package-level application guidance, verified family specifications, and an explicit distinction between electrically similar alternatives and confirmed drop-in choices. It also identifies unavailable pricing, lifecycle, and detailed pin-assignment data rather than inferring those values from the MPN.

The verified device information identifies 64 macrocells, 30 user I/Os, 3.3 V operation, 5.0 ns speed grading, a 227.27 MHz maximum frequency, 44-pin TQFP construction, and industrial-grade temperature positioning. Its in-system programming capability allows a board manufacturer to load or update the logic configuration during manufacturing, test, or field operation without removing the device from the circuit. The LC4064V-5T44I is part of Lattice Semiconductor's SuperFAST high-density ispMACH 4000V family. The 5.0 ns grade is intended for designs requiring faster logic propagation than slower members of the family, while the 64 macrocells provide a moderate capacity for consolidating multiple fixed functions into one programmable device. The 30 available user I/Os support connections to external memories, control signals, communications peripherals, and mixed-signal system blocks. Typical uses include industrial controller logic, data-acquisition interfaces, instrumentation, embedded system glue logic, protocol conversion, and legacy bus-interface consolidation. Its fixed-capacity architecture and in-system programmability are especially useful when a design must deliver deterministic behavior without the resource overhead and configuration complexity of a larger FPGA. A critical design consideration is the 44-pin TQFP footprint and its 30 user I/O complement. The PCB must match the manufacturer's land pattern, preserve adequate clearance around all leads, and route high-speed or sensitive signals away from noisy switching nodes. Because verified pricing and detailed electrical limits were not present in the supplied records, designers should confirm the complete manufacturer datasheet and current distributor inventory before release. This page consolidates verified distributor and datasheet-search records, same-family drop-in alternatives, technical comparisons, and practical selection guidance. It distinguishes confirmed device facts from missing electrical, pinout, pricing, and lifecycle details so that engineers can make a qualified sourcing or design decision without relying on unverified assumptions.
LC4064V-5T48C - 64-Macro-Cell 227 MHz CPLD | Lattice
The Lattice Semiconductor LC4064V-5T48C is an in-system-programmable CPLD with 64 macro cells, 32 I/O, a 227 MHz maximum operating frequency, and a 48-pin TQFP package. It belongs to the ispMACH 4000V family of SuperFAST high-density programmable logic devices and supports 3.3 V, 2.5 V, and 1.8 V supply configurations. The -5 speed designation corresponds to a 5 ns class of device, while the family specification identifies a maximum system frequency of 227 MHz. A CPLD, or complex programmable logic device, is a programmable-logic semiconductor that combines configurable logic blocks, programmable interconnect, and I/O resources. In the product hierarchy, a CPLD is a programmable logic device, a form of FPGA & CPLD semiconductor, and a practical alternative to a small gate array when deterministic logic, nonvolatile configuration, and in-system reprogrammability are more important than very high logic density. The LC4064V family targets control, interface, glue-logic, and signal-routing functions. Key features include 64 macro cells, 32 user I/O, in-system programmability, and a nominal 5 ns speed grade. Its 3.3 V, 2.5 V, and 1.8 V operating options provide flexibility across legacy industrial and embedded control systems. The 48-pin TQFP package also supports conventional PCB assembly and inspection processes. The source data identifies the device as a SuperFAST high-density PLD and part of the ispMACH 4000V family. Technically, the LC4064V-5T48C is best understood as a compact, nonvolatile logic platform rather than a general-purpose processor. Macro cells implement registered or combinational logic, while programmable interconnect routes signals among the cell array and package pins. In-system programming allows the same board to be configured or updated without removing the device, provided the associated programming interface, power rails, and signal conditions meet the device requirements. Typical uses include industrial control interfaces, peripheral bus decoding, legacy display and memory glue logic, automotive or communications equipment, and embedded system sequencing. The 32-I/O configuration is suitable for moderate pin-count interfaces rather than high-channel-count parallel buses. Engineers should account for available macro cells, I/O standards, timing constraints, and programming voltage when designing around the device. The primary design consideration is availability: available sources label LC4064V-5T48C as obsolete, so new production designs should confirm lifecycle status before committing to a long-term program. For an existing PCB, the 48-pin TQFP footprint and -5 speed grade must be preserved, and any replacement should be checked for identical pin functions, voltage support, macro-cell architecture, and timing behavior. This page consolidates verified distributor specifications, family-level technical details, source-backed replacement candidates, pricing availability, and practical migration guidance. It separates confirmed LC4064V-5T48C data from parameters that require confirmation in the manufacturer datasheet, helping engineers assess fit, sourcing risk, and drop-in replacement feasibility more efficiently.
LC4064V-5T48I - SuperFAST High-Density PLD | Lattice

The device is identified as a 3.3V, 2.5V, and 1.8V in-system programmable CPLD, allowing it to support multiple supply-voltage arrangements in compact embedded systems. Its 48-pin TQFP package and industrial-grade ordering code make it suitable for designs requiring deterministic programmable control, signal conditioning, interface bridging, and logic consolidation. A complex programmable logic device is a programmable semiconductor that combines multiple programmable logic blocks, interconnect resources, and input/output structures into one configurable integrated circuit. Within the device hierarchy, a CPLD is a programmable logic device, a semiconductor, and an alternative to a small FPGA or discrete gate-array implementation. LC4064V-5T48I provides in-system programmability, allowing a design to be programmed after PCB assembly when a suitable programming path and device support are available. The verified device family information identifies the LC4064V as a high-density PLD offering a flexible combination of logic capacity, low power, and performance. The part suffix denotes a -5 speed grade and an industrial temperature option, while the 48 suffix identifies the 48-pin package configuration. These details make the MPN suitable for industrial control logic, data acquisition interfaces, communication control, and embedded system support functions where a consolidated programmable device can reduce board complexity. The LC4064V family supports 3.3V, 2.5V, and 1.8V operation. This voltage flexibility is important when a board uses multiple logic voltage domains, although designers must still observe the exact pin, voltage, timing, and power requirements documented for the selected device and package. The -5 grade should be selected when the design requires the family’s faster timing grade rather than a slower speed option. Typical applications include programmable I/O expansion, bus-interface control, industrial machine sequencing, communication protocol handling, and general-purpose glue logic. The 48-pin TQFP package also provides a practical surface-mount footprint for manufacturing and allows access to a larger number of package pins than smaller CPLD packages. Because the verified data does not provide detailed logic-block counts, I/O counts, timing tables, or exact pin names, those values should be confirmed in the manufacturer datasheet before final schematic or PCB sign-off. Designers should verify the device’s complete pinout, power-supply sequencing, decoupling requirements, and programming interface against the manufacturer documentation. The TQFP-48 package should be routed with adequate thermal and solder-joint consideration, and unused inputs should be handled according to the device recommendations. This page combines the verified family description, sourcing information, same-package alternatives, and practical selection guidance; it does not replace the complete electrical and timing data in the manufacturer datasheet.
LC4128V-75TN100C - 128-Macrocell CPLD, 7.5ns TQFP-100 | Lattice
The Lattice Semiconductor LC4128V-75TN100C is a 128-macrocell, 3.3V/2.5V/1.8V In-System Programmable SuperFAST High-Density CPLD from the ispMACH 4000V family, housed in a 100-pin TQFP (TN) package. It delivers a 7.5 ns pin-to-pin propagation delay (tPD) and supports a 400 MHz maximum internal operating frequency, making it one of the fastest non-volatile logic devices in its density class. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic device that implements combinatorial and sequential logic in a single chip, typically organized as multiple PAL-like logic blocks connected by a programmable interconnect matrix. CPLDs sit below FPGAs in logic density but offer faster, more deterministic propagation delays and instant wake-up from power-on, which is why they are favored for glue logic, bus bridging, and control-plane applications. Key features of the LC4128V-75TN100C include 128 macrocells across 4 logic blocks (32 macrocells per block), 64 user I/O pins, JTAG-based IEEE 1149.1 boundary-scan and in-system programmability, four global clock pins with programmable polarity, and a 3.3V core with multi-voltage I/O supporting 1.8V, 2.5V, and 3.3V interfaces. Power consumption is managed through per-macrocell product-term steering and a low-power standby mode. The device is built on a non-volatile E2CMOS process, which means configuration is retained without external memory and the part is ready to operate within microseconds of power-up. The wide I/O voltage compatibility allows direct interfacing with legacy 5V-tolerant buses through external resistors and with modern 1.8V/2.5V/3.3V processors without level shifters. Typical applications include bus-interface bridging (PCI to local bus, address decoding), glue logic in industrial controllers, power-sequencer replacement of discrete logic, and feature expansion for ASIC/microcontroller pin-limited designs. It is commonly used in telecom line cards, motor-control boards, and instrumentation front-ends where deterministic timing is required. When designing with the LC4128V-75TN100C, ensure the JTAG chain order is correctly defined for ISP, observe the 3.3V supply ramp requirements, and verify that the chosen I/O standard matches the bank voltage. Unused I/O pins must be configured as outputs or tri-stated with the proper termination to avoid leakage. This page consolidates distributor pricing, true drop-in same-package alternatives, application circuit notes, and design-time considerations that the manufacturer datasheet does not compile on a single page, helping engineers shorten evaluation cycles.
LC4128ZE-7MN144C - 128-Macrocell 1.8V Ultra-Low-Power CPLD | Lattice
The Lattice Semiconductor LC4128ZE-7MN144C is a 128-macrocell ultra-low-power CPLD from the ispMACH 4000ZE family, housed in a 144-ball CSBGA (7x7 mm, 0.5 mm pitch) package. It features 96 user I/O, 8 logic blocks, a 7.5 ns pin-to-pin propagation delay (tpd), and a maximum internal operating frequency of 172 MHz. The device operates from a single 1.8 V core supply (1.7 V to 1.9 V) and is in-system programmable through a standard IEEE 1532 / JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like AND/OR arrays with a central switch matrix. CPLDs sit between discrete glue logic (74-series gates) and FPGAs in the programmable logic hierarchy: like discrete logic they boot instantly from on-chip flash, and like FPGAs they implement arbitrary combinatorial and sequential functions. The ispMACH 4000ZE family specifically targets battery-powered and portable applications where static and dynamic power consumption are critical. Key differentiating features include Lattice's ultra-low-power 1.8 V architecture, per-pin slew-rate control, 3.3 V tolerant I/O with 5 V tolerant inputs, in-system programmability via JTAG, and a commercial operating temperature range of 0C to +90C (TJ). The CSBGA-144 package is footprint-compatible with the rest of the ispMACH 4000ZE family (64, 128, 256, and 512 macrocell densities in the same 144-ball outline where applicable), enabling designers to migrate density up or down without PCB rework. Architecturally, each macrocell contains a programmable AND array feeding an OR array, a flip-flop, and a feedback path. Eight logic blocks are interconnected by a global routing pool, providing predictable, deterministic timing with zero-fanout delays independent of placement. This makes the LC4128ZE-7MN144C well suited to replace multiple 74LV logic chips with a single in-system reconfigurable device while preserving exact cycle-accurate behavior. Typical applications include portable handheld and battery-powered consumer products, digital camera and camcorder glue logic, low-power instrumentation, LCD display timing controllers, and I2C/SPI/UART bus bridging/level shifting. The ultra-low static current also makes it attractive as a power-management sequencer in always-on subsystems of larger SoCs. Designers should note that 96 I/O is the maximum user I/O count - the actual usable count depends on JTAG programming pin sharing. Always use Lattice's ispLEVER Classic or Lattice Diamond (with the ispMACH 4000ZE support files) for synthesis and fitting to guarantee timing closure. The CSBGA package requires careful PCB layout with microvia or via-in-pad technology to escape the 0.5 mm ball pitch. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone.

The HC devices integrate an internal linear voltage regulator that allows single-supply operation while supporting I/O bank voltages from 1.2 V to 3.3 V. The HC variant (high-performance, with linear regulator) sits between the ZE ultra-low-power variant and the HE high-performance with enhanced I/O variant. Pin selection across HC, HE and ZE families is compatible at the same package, allowing power-tier upgrades on the same PCB. The device supports instant-on via internal Flash, SPI, I2C and parallel configuration ports, and includes embedded hard IP for common bridging protocols. Typical applications include I/O expansion and bus bridging for consumer and industrial boards, glue logic replacement, LED control, system monitoring, and low-density control PLD functions. Industrial automation, IoT edge nodes, and portable consumer designs use MachXO2 for its instant-on and low standby current. When selecting a MachXO2, consider standby power (ZE lowest), I/O performance (HE fastest edges, more I/O standards), and internal regulator (HC and HE include, ZE requires external 3.3 V). For -4SG32C users, the package and pinout allow migration to ZE and HE versions without PCB changes.

Typical uses include sensor conditioning, motor and actuator control, industrial data acquisition, communication bridges, embedded test logic, and low-volume control systems. The TG100 package is large enough for a substantial number of board connections while remaining suitable for conventional surface-mount PCB assembly. Designers should verify the exact pin functions, I/O standards, configuration requirements, power sequencing, and unused-pin treatment against the Lattice MachXO2 family datasheet before layout release. For robust implementation, treat configuration storage, JTAG access, power rails, decoupling, I/O voltage compatibility, and unused I/O as deliberate design decisions. The listed 22 uW standby power is a standout low-power figure, but actual system consumption depends on the selected configuration, clocking, I/O activity, and enabled power-saving modes.

Key features of the LCMXO2-256HC-4SG32C include a built-in programmable Flash memory eliminating the need for an external configuration PROM, a dedicated FIFO control logic block supporting widths from 4 to 36 bits and depths from 16 to 4096, programmable low-swing differential I/O for LVDS-style signaling, and a -4 speed grade that delivers 7.24 ns propagation delay. Multiple power-saving modes (Standby, Sleep, and I/O-disable) lower quiescent consumption for battery-fed designs. Architecturally the device combines LUT4-based logic slices with on-chip flash, an embedded block RAM, PLL-style clock conditioning, and hardened I/O buffers. The 65 nm process and the integrated Flash allow instant-on start-up within microseconds, making the device useful as a system supervisor that boots before the main processor. The exposed-pad QFN package also provides a low-thermal-resistance path for mildly elevated dissipation during high toggle activity. Typical applications include I/O expansion and level shifting in routers and embedded boards, control logic for displays and backlight drivers, power-up sequencing and housekeeping in server / storage platforms, sensor aggregation in industrial IoT nodes, and low-power handheld devices that benefit from the 19 µW standby figure. When designing with this part, plan decoupling carefully: place 0.1 µF and 1 µF MLCCs adjacent to each VCC/VCCAUX pin pair and stitch the exposed pad to a continuous ground plane to manage thermal performance. Verify your IO bank voltage configuration before generating the bitstream; mismatched VCCI banks and LVCMOS standards are the most frequent build failures.
