LC4064V-5T48I - SuperFAST High-Density PLD | Lattice
부품 번호: LC4064V-5T48I ✗ 단종LC4064V-5T48I 개요
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.

일반적인 애플리케이션
LC4064V-5T48I 적합 용도: 6 애플리케이션s: Industrial Control Logic, Programmable Interface Bridging, Data Acquisition Control, Communication Protocol Control, Programmable I/O Expansion, Embedded System Glue Logic.
Industrial Control Logic
The LC4064V-5T48I fits industrial control logic where programmable sequencing, conditional branching, and interface consolidation are useful. Its industrial-grade ordering designation makes it the preferred candidate among the verified LC4064V variants when the equipment must operate across an industrial temperature range. The -5 speed grade can support higher-speed control loops than a slower -10 option, provided the design is checked against the manufacturer timing tables. Designers can use the CPLD to consolidate machine-state logic, interlock processing, and discrete timing functions without relying on a large FPGA. The 48-pin TQFP package also provides a conventional surface-mount assembly format suitable for industrial control boards.
추천
Programmable Interface Bridging
The LC4064V-5T48I can implement protocol conversion, signal alignment, and programmable I/O bridging between embedded subsystems. Its support for 3.3V, 2.5V, and 1.8V operation makes it relevant to mixed-voltage logic designs, although each bank or I/O standard must be checked against the complete manufacturer datasheet. Use the -5 grade when interface timing margins are limited and use the in-system programming capability to simplify configuration updates. Compared with a discrete gate-array implementation, the CPLD provides a compact integrated solution with programmable routing and logic blocks.
추천
Data Acquisition Control
The LC4064V-5T48I is suitable for acquisition-system control logic that coordinates sensor selection, sampling sequences, data strobes, and status reporting. The -5 grade offers a faster timing option than the LC4064V-10TN48I, making it preferable when the controller must meet tighter setup and hold margins. Its programmable architecture allows acquisition sequencing to be revised without changing the PCB. Exact input count, output count, operating frequency, and electrical limits were not supplied in the verified data, so designers must confirm that the 48-pin package provides enough resources for the selected channel count.
추천
Communication Protocol Control
The LC4064V-5T48I can implement programmable framing, command decoding, parity generation, and interface arbitration for embedded communication equipment. In-system programmability allows the same PCB hardware to support protocol revisions or configuration updates, while the 3.3V, 2.5V, and 1.8V operating options support mixed-voltage system architectures. The -5 grade is appropriate when clock and data-path margins are more important than unit cost. Validate signal standards, I/O direction, timing, and programming pins against the complete Lattice documentation before using the device in a communication interface.
추천
Programmable I/O Expansion
The LC4064V-5T48I is a candidate for expanding control and status I/O without adding multiple fixed-function logic packages. Programmable pin assignments and logic can consolidate debounce, latch, pulse-generation, and state-machine functions around a 48-pin TQFP footprint. The industrial-grade designation and -5 speed grade make it more appropriate than the commercial-grade LC4064V-5T48C for harsh operating environments. Before design freeze, verify that the exact device has the required number and type of user I/O and that all unused pins are handled according to the manufacturer guidance.
추천
Embedded System Glue Logic
The LC4064V-5T48I is well suited to glue-logic roles such as reset sequencing, interrupt arbitration, watchdog supervision, peripheral selection, and bus-cycle decoding. A single CPLD can replace several FPGA, GAL, counter, and latch packages while allowing functional changes through programming. Its in-system programmability supports production testing and later configuration updates, and the -5 speed grade helps preserve timing margin in systems with several synchronous peripherals. The principal design trade-off is that the exact resource count and timing must be checked in the manufacturer datasheet before relying on the device for a new design.

설계 노트
Do not treat the family suffix alone as proof of drop-in equivalence. Compare the complete manufacturer pin table, speed-grade limits, temperature range, supported supply voltages, I/O standards, and configuration interface for the LC4064V-5T48I and the proposed alternative. In particular, LC4064V-10TN48I is a -10 speed grade and may fail a design requiring the -5 grade even though both use the same 48-pin package. Record the approved alternate MPN in the schematic and BOM notes after engineering review.
The verified family information states support for 3.3V, 2.5V, and 1.8V, but it does not specify which I/O banks or supply pins support every voltage. Before connecting external signals, verify VCC and I/O reference requirements in the manufacturer datasheet, including input thresholds and output drive capability. Place the recommended bypass capacitors adjacent to the corresponding power pins and keep the return path short, while avoiding assumptions that every 1.8V, 2.5V, or 3.3V interface combination is automatically supported.
Use the manufacturer package drawing for the 48-pin TQFP footprint and verify pin-1 orientation, courtyard, solder mask, and paste-aperture dimensions against the current Lattice documentation. Route configuration signals and clock inputs away from noisy switching nodes, provide a stable ground reference, and reserve accessible test points for programming and validation. Because exact pin assignments were not included in the verified data, complete placement and routing must wait until the datasheet pinout has been cross-checked.
규정 준수 정보
