LC4064V-5T44C - 5 ns 64-Macrocelle ISP CPLD | Lattice
料号： LC4064V-5T44C ✗ 停产LC4064V-5T44C 概述
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.

典型应用
LC4064V-5T44C 适用于 6 应用s: Peripheral Interface Bridging, Industrial Control Logic, Data Format Conversion, Embedded System Control, Bus Interface Adaptation, Programmable Test and Control Fixture.
Peripheral Interface Bridging
The LC4064V-5T44C fits peripheral-interface bridging because it combines 64 macrocells, four logic array blocks, and 30 user I/O pins in a compact 44-TQFP package. According to the supplied Lattice-family information, its 5 ns propagation delay provides useful timing margin for short combinational paths between slower host peripherals and external logic. The device can implement protocol conversion, address decoding, and handshake control without occupying a larger FPGA. In-system programming from 3.3 V, 2.5 V, or 1.8 V also allows board-level updates when the programming interface and isolation requirements are implemented as directed by the datasheet.
推荐
Industrial Control Logic
The LC4064V-5T44C is suitable for compact industrial control logic when its exact operating-temperature and qualification ratings are confirmed. Its 64 macrocells and 30 user I/O provide capacity for sequencing, interlocks, signal conditioning, and state-machine functions, while the 5 ns propagation delay supports faster control paths than slower family grades. The 44-TQFP package is practical for multilayer control boards, although the four-sided lead arrangement still requires careful fanout planning. In-system programming can simplify field updates, but isolation, surge protection, and functional-safety requirements remain board-level responsibilities rather than properties established by the supplied search results.
推荐
Data Format Conversion
The LC4064V-5T44C can implement compact data-format conversion and bus-adaptation logic using its 64 macrocells and four logic array blocks. The 5 ns propagation delay is valuable when conversion logic must operate between interfaces with different clock or latency characteristics, although actual throughput depends on the implemented path and I/O timing. Thirty user I/O pins permit multiple parallel data and control paths within the 44-pin package. For production use, engineers should verify supported I/O standards, setup and hold requirements, and whether double-buffer or registered I/O features are needed for the target interface before finalizing the pin assignment.
推荐
Embedded System Control
The LC4064V-5T44C fits embedded system control when a microcontroller requires deterministic external glue logic. Its 64 macrocells can implement command sequencing, watchdog, alarm, and peripheral arbitration functions, while the 5 ns propagation delay can reduce uncertainty in short control paths. The 30 user I/O pins provide direct board-level connectivity without an external programmable-logic device. The 44-TQFP package also supports compact mixed-signal assemblies. Design teams should reserve configuration and programming access, validate power sequencing against the datasheet, and use static timing analysis to confirm that the selected macrocell and routing paths meet the control system timing budget.
推荐
Bus Interface Adaptation
The LC4064V-5T44C is appropriate for adapting legacy or mismatched bus signals because it combines 30 user I/O pins with four logic array blocks and 64 macrocells. Its 5 ns propagation delay can support short interface paths, while the in-system-programmable architecture permits different logic configurations for board revisions. Potential tasks include signal translation, interrupt qualification, bus arbitration, and command preprocessing. The supplied evidence does not enumerate the device's supported I/O standards, so engineers must compare input thresholds, output levels, slew behavior, and timing against every connected device. A shared ground reference or suitable isolation arrangement is also required depending on the interface architecture.
推荐
Programmable Test and Control Fixture
The LC4064V-5T44C can serve as programmable logic in test fixtures, interface conditioners, and sequencing controllers. Its 64 macrocells and 30 user I/O provide enough parallel resources for controlling multiple instrument or DUT signals, while the 5 ns delay supports deterministic path timing. In-system programmability allows fixture behavior to be revised by changing the configuration rather than redesigning the interconnect board. The TQFP package is easy for automated assembly, but test engineers should account for the limited routing channels beneath the package and use the manufacturer's timing models to confirm setup and hold margins at the fixture boundary.

设计说明
Confirm the target revision's exact supply-voltage, input-threshold, and output-level limits before assigning I/O pins. The supplied data establishes a 3 V to 3.6 V internal supply and supports 3.3 V, 2.5 V, and 1.8 V programming supplies, but it does not provide the complete DC electrical table. Place the required supply and ground decoupling capacitors close to their device pins, use the datasheet-recommended values and topology, and account for switching current when external devices share the same rail.
Plan routing around the 44-TQFP footprint's four-sided lead arrangement. Although the package is only 10 x 10 mm, its 44 leads can constrain escape routing on multilayer boards, especially when the CPLD drives buses or point-to-point interfaces directly beneath the device. Follow the manufacturer package drawing and land pattern, preserve adequate solder-mask and paste control, and avoid placing sensitive analog or high-speed clock nets under the IC where they could couple to switching edges.
Do not treat a related LC4064V suffix as an automatically identical part. The -5, -6, -7, and -10 portions denote different speed grades, while N, I, C, and V suffixes can identify temperature, qualification, or device-family differences. For every proposed replacement, compare configuration-file compatibility, pin functions, I/O standards, supply limits, absolute maximum ratings, and timing. A shared 44-TQFP package is necessary for a drop-in migration but does not prove functional interchangeability.
Use the datasheet timing models to evaluate every implemented path rather than relying only on the 5 ns headline propagation delay. Add external-device setup and hold time, clock uncertainty, and board-level skew to the analysis. For externally exposed signals, confirm the available I/O standard, drive strength, slew rate, and termination strategy. In-system programming introduces additional signals and board-state considerations, so isolate or disable conflicting interfaces during configuration as specified by the manufacturer.
合规信息
The supplied search results do not extract compliance declarations for the exact LC4064V-5T44C. RoHS and REACH status must be confirmed from the current manufacturer or distributor product record before procurement.
