LC4032V-5T48I - 32-Macrocell 5 ns CPLD | Lattice
部品番号: LC4032V-5T48I ✓ 生産中LC4032V-5T48I 概要
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.

主な用途
LC4032V-5T48I の用途: 6 件s: Industrial Control Logic, Communication Interface Decoding, Bus Arbitration and Data Routing, Peripheral Interfacing, Embedded State-Machine Control, LED and Display Control.
Industrial Control Logic
The LC4032V-5T48I fits compact industrial control functions because it combines 32 macrocells, 32 I/O pins, two logic blocks, and a 5 ns nominal propagation delay in a TQFP-48 package. Its verified industrial junction-temperature range of -40°C to 105°C supports equipment expected to operate across extended temperature conditions. A designer can use the CPLD for command decoding, interlocks, sequencing, and peripheral control without a large FPGA. The implementation must be checked against the available macrocell and routing resources, and all critical paths should be analyzed with worst-case timing rather than the nominal 5 ns figure alone.
Communication Interface Decoding
LC4032V-5T48I is suitable for communication-interface glue logic where multiple signals must be decoded, formatted, or routed deterministically. Its 32 I/O pins provide a moderate interface budget, while the 5 ns propagation delay supports short combinational paths and registered control functions. The 3.3 V, 2.5 V, and 1.8 V operating options can simplify mixed-voltage interface designs, although each I/O’s allowed voltage must be verified individually. Engineers should use the CPLD for protocol framing, command qualification, error handling, and handshake logic rather than relying on it for high-throughput datapath processing that exceeds its logic capacity.
Bus Arbitration and Data Routing
The LC4032V-5T48I can consolidate bus-arbitration, address-decoding, mux, and sequencing logic in a single TQFP-48 device. With 32 macrocells and two logic blocks, it is appropriate for moderate control paths that require deterministic in-system programmability rather than a large programmable-logic array. The 5 ns speed grade can provide useful timing margin for local decoding when registered boundaries are used. Design verification should include contention cases, reset behavior, clock-domain assumptions, and the configuration state at power-up. Because the exact I/O standards and pin assignments are absent from the supplied search data, interface-level validation must use the manufacturer datasheet.
Peripheral Interfacing
LC4032V-5T48I can bridge dissimilar peripherals by implementing selectable data paths, register files, chip-select logic, and protocol converters in one programmable-logic device. Its 32 user I/O pins and support for 3.3 V, 2.5 V, and 1.8 V operation are useful when legacy and modern peripherals coexist. The two logic blocks and 32 macrocells should be mapped against the required equations and routing to ensure adequate utilization. Use the in-system programming capability to simplify manufacturing programming, but validate configuration pins, ISP timing, and power-up behavior exactly as specified by Lattice.
Embedded State-Machine Control
A compact finite-state machine for sequencing, fault handling, or mode control is a practical use for the LC4032V-5T48I. The 32 macrocells provide dedicated programmable logic, while the 5 ns propagation delay supports timing-sensitive control paths and registered outputs. The device is particularly useful when control logic must be changed during maintenance while remaining non-volatile between power cycles. Designers should define state-transition timing, illegal-state recovery, reset ownership, and clock-domain boundaries before implementation. If the machine requires more storage, I/O, or throughput than the two logic blocks and 32 I/O pins provide, migration to a larger CPLD should be considered before layout.
LED and Display Control
LC4032V-5T48I can implement display multiplexing, LED sequencing, blanking control, keypad scanning, and fault indicators in compact embedded systems. Its 32 I/O pins offer enough connectivity for moderate display and indicator structures, while in-system programmability simplifies product configuration and board rework. The 5 ns timing class is appropriate for ordinary scan and decode logic but does not eliminate the need to specify output timing, drive limits, and electrical standards. Because the available data does not identify supported I/O types or individual output capabilities, the PCB and firmware design must be checked against the manufacturer electrical tables before LEDs or display loads are connected.

設計ノート
Treat the LC4032V-5T48I as a TQFP-48 programmable-logic device and assign its PCB footprint only from the current Lattice package drawing. Keep configuration pins, clock inputs, and ground connections consistent with the datasheet reference schematic. The verified web results do not expose individual pin assignments, so engineers must not infer power or configuration locations from another speed grade or package drawing.
Use the manufacturer-recommended decoupling and configuration network exactly as specified in the datasheet, and keep high-speed or externally exposed nets short and properly terminated. Although the device has a 5 ns nominal propagation delay, board propagation, loading, I/O standards, and clock skew still determine usable system timing. Analyze worst-case timing and use registered boundaries for interfaces whose source-synchronous behavior cannot be guaranteed by the CPLD timing tables.
Do not approve a speed-grade substitution solely because it has the same TQFP-48 outline. Confirm that LC4032V-5TN48C, LC4032V-4T48I, LC4032V-6T48I, or LC4032V-7T48I has matching power pins, configuration pins, I/O functions, input thresholds, output-drive limits, and timing guarantees. A slower variant must satisfy every setup-and-hold requirement, while a faster or commercial-temperature variant does not relax the original industrial and timing constraints.
Budget power from the actual configured logic, I/O activity, and supply voltage rather than from the device name alone. The available evidence confirms 3.3 V, 2.5 V, and 1.8 V operation but does not provide quiescent current, dynamic-current curves, or per-I/O loading data. Obtain those values from the manufacturer electrical characteristics before sizing the supply, placing bulk capacitance, or estimating thermal rise.
コンプライアンス情報
The verified search results identify the product as an industrial-temperature Lattice CPLD but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from the current manufacturer product page, material declaration, or distributor classification.
