LC4064C-5T44C - 64-Macrocell 5 ns CPLD | Lattice Semiconductor
料号： LC4064C-5T44C ✗ 停产LC4064C-5T44C 概述
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.

典型应用
LC4064C-5T44C 适用于 6 应用s: Industrial Automation Control, Communication Interface Bridging, Data Acquisition Conditioning, Embedded System Control, Test and Measurement Logic, Programmable Peripheral Controller.
Industrial Automation Control
The LC4064C-5T44C fits compact machine-control logic because its 64 macrocells can implement interlocks, sequencers, counters, alarm logic, and actuator-control functions in one device. The listed 5 ns speed grade and 227 MHz maximum operating frequency provide useful timing margin for fast control paths, while up to four global clock inputs support coordinated state-machine operation. Its in-system-programmable architecture also permits configuration changes during production or maintenance. Before deployment, verify the industrial temperature range, I/O standards, isolation requirements, and safety controls because those details are not present in the supplied data.
推荐
Communication Interface Bridging
The LC4064C-5T44C is suitable for protocol conditioning and interface bridging because 64 macrocells can combine state machines, bus arbitration, level translation control, and programmable I/O logic. Its listed 2.5 ns propagation delay and 227 MHz maximum operating frequency support interface paths that need more margin than a slower CPLD grade. The device is especially useful for legacy systems requiring nonvolatile, in-system reconfiguration. Designers must still confirm the exact I/O voltage, slew, drive-strength, and timing limits for every external bus before releasing the PCB.
推荐
Data Acquisition Conditioning
The LC4064C-5T44C can implement acquisition front-end control, channel sequencing, trigger qualification, counters, and data-format conversion in a compact 44-pin TQFP package. The 5 ns speed grade provides timing margin for synchronous control logic, while the 64 macrocells allow multiple pipeline and decoding functions to be consolidated. In-System Programmability simplifies board bring-up and firmware-driven logic updates. The supplied information does not specify the device's I/O standards or analog-adjacent interfaces, so the CPLD should control digital acquisition functions rather than directly perform high-precision analog conversion.
推荐
Embedded System Control
The LC4064C-5T44C fits embedded glue-logic roles that require deterministic control without the resource cost of a larger FPGA. Its 64 macrocells can implement watchdog timers, boot-mode decoding, reset coordination, address translation, and peripheral glue around a host processor. The listed 227 MHz maximum operating frequency is suitable for many synchronous supervisory paths, and the nonvolatile configuration supports field updates. For a production design, check power sequencing, configuration-pin behavior, I/O compatibility, and startup timing against the exact manufacturer documentation.
推荐
Test and Measurement Logic
The LC4064C-5T44C is appropriate for test-equipment sequencing, trigger generation, timing control, pattern conversion, and front-panel state management. The 5 ns speed grade allows short combinational paths, while 64 macrocells provide enough capacity to combine counters, state machines, and signal-routing logic in a single device. Its in-system programming allows calibration tables or test sequences to be updated through the system. Engineers should verify that every instrument signal uses a supported I/O standard and that timing closure includes probe, cable, and instrument loading effects.
推荐
Programmable Peripheral Controller
The LC4064C-5T44C can consolidate multiple peripheral functions into a low-complexity controller by implementing registers, interrupts, command decoders, and timing blocks in its 64 macrocells. The listed 227 MHz maximum operating frequency supports common embedded peripheral rates, while the compact 44-pin TQFP package simplifies board density. In-System Programmability is valuable for product variants that share one PCB but require different configuration files. Final design approval should confirm package dimensions, exposed-pad requirements, supply sequencing, and the precise supported I/O configurations in the manufacturer datasheet.

关键差异点
- Faster ordering grade within the same LC4064C family （对比 LC4064C-25T44C)
- Commercial-grade suffix with the target's 5 ns speed class （对比 LC4064C-5T44I)
- Closest verified speed-and-package alternative （对比 LC4064V-5T44C)
设计说明
Do not approve a replacement based only on the 44-pin TQFP package and speed-grade suffix. Confirm the complete manufacturer pin table, configuration pins, supply pins, I/O multiplexing rules, supported voltage combinations, and package dimensions. The LC4064C speed-grade variants are the strongest candidates for timing-compatible substitution, while LC4064V-5T44C requires additional verification because the V-family architecture may differ despite sharing the package and 5 ns designation.
Create explicit clock, reset, and configuration constraints in the design tool and verify post-layout timing at the actual operating voltage and temperature. The listed 227 MHz maximum operating frequency is a device-family capability rather than a blanket guarantee for every path. Include external clock skew, output loading, input threshold behavior, and board-level rise or fall time in the timing review rather than checking only the numerical clock period.
Place the device's decoupling and configuration circuitry according to the manufacturer reference layout, keeping supply and ground connections short and providing a low-impedance return path. Confirm whether the 44-pin TQFP has an exposed thermal pad or other thermal land requirements in the specific package drawing. Validate every external interface voltage against the supported I/O standards and provide the required logic levels during configuration, reset, and normal operation.
Verify the selected core and I/O supply voltages independently against the LC4064C family electrical table; the verified search result states 1.8 V, 2.5 V, and 3.3 V support but does not identify every valid supply combination. Include configuration-pin pull states, inrush, and sequencing requirements in the power analysis. Do not substitute a different speed or family suffix solely because its nominal voltage appears similar.
合规信息
The supplied verified results do not explicitly state the LC4064C-5T44C's RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because this is a programmable logic IC rather than an automotive-qualified device.
