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.

典型应用
LC4064V-5T48C 适用于 6 应用s: Industrial Control Interface Logic, Peripheral Bus Address Decoding, Legacy Display and Memory Glue Logic, Automotive Body and Auxiliary Control, Communications Equipment Control Plane, Embedded System Power and Reset Sequencing.
Industrial Control Interface Logic
The LC4064V-5T48C fits legacy industrial control boards that require deterministic combinational and registered logic close to the interface circuitry. Its 64 macro cells provide 32 I/O and a 5 ns-class speed option for decoding commands, coordinating interlocks, multiplexing status signals, and sequencing discrete actuators. The 48-pin TQFP package is convenient for conventional PCB assembly, while in-system programming allows board-level configuration updates. Before deployment, verify the exact power pins, I/O voltage tolerance, operating-temperature grade, and timing margins against the manufacturer datasheet because those values were not present in the supplied data.
推荐
Peripheral Bus Address Decoding
The LC4064V-5T48C can implement address decoding, chip-select generation, bus arbitration, and data-routing functions for embedded systems with modest interface requirements. Its 64 macro cells and 32 I/O are suitable for coordinating several peripheral signals without relying on a large FPGA. The listed 227 MHz maximum frequency and 5 ns speed designation provide substantial timing headroom for many control-plane operations. The designer must still map each signal through the actual pin table, respect the selected bank voltage, and include contention-safe defaults in the CPLD configuration before allowing external devices to drive the bus.
推荐
Legacy Display and Memory Glue Logic
For legacy display, memory, and peripheral boards, the LC4064V-5T48C can combine address generation, display timing, and control-signal multiplexing in one programmable device. In-system programmability is useful when several board variants share a common design but require different display or memory interfaces. The 32 available I/O provide enough connectivity for small, non-high-speed buses, while the 48-pin TQFP simplifies adaptation to existing artwork. Designers should confirm whether the target memory interface requires signals beyond the 227 MHz device-class maximum or uses voltage levels not supported by the selected LC4064V configuration.
推荐
Automotive Body and Auxiliary Control
The LC4064V-5T48C can be evaluated for body-control, auxiliary-switch, actuator-sequencing, and signal-conditioning logic in legacy vehicle electronics. Its 64 macro cells and 32 I/O support centralized decoding of switches and interlocks, and the compact 48-pin TQFP suits space-constrained controller boards. The supplied data confirms the device family and package but does not confirm automotive qualification, temperature limits, transient immunity, or AEC-Q100 status. Those requirements must be verified before installation in a vehicle; otherwise, the part should be restricted to non-safety-critical auxiliary functions or used only in previously qualified legacy hardware.
推荐
Communications Equipment Control Plane
The LC4064V-5T48C is appropriate for control-plane functions in communications equipment, including status multiplexing, command framing, alarm logic, and backplane signal conditioning. The 32-I/O device avoids the resource overhead of a much larger FPGA, while its 227 MHz listed maximum supports common control-clock rates. In-system programming can simplify board revision changes because the logic configuration may be updated without replacing the device. However, data-path traffic should use a dedicated interface or FPGA when it requires continuous high-speed throughput, and the designer must confirm actual I/O standards and package-level timing for the target interface.
推荐
Embedded System Power and Reset Sequencing
The LC4064V-5T48C can implement deterministic power-up, reset, watchdog, enable, and interlock sequencing for embedded subsystems. Its 64 macro cells are sufficient for combining asynchronous status inputs into ordered control outputs, while the 5 ns-class timing allows short combinational delays. The device is particularly useful in legacy systems that already provide a stable configuration rail for in-system programming. Because the supplied data does not state supply current, output drive strength, or power-down behavior, the logic should avoid driving loads directly and should use appropriate buffers when controlling external reset or power-enable lines.

设计说明
Do not treat a matching 48-pin TQFP outline or similar -5 speed suffix as proof of interchangeability. Compare the manufacturer pin tables for VCC, GND, programming signals, configuration pins, clock pins, and every user I/O before ordering a substitute. Also verify supported supply voltages and I/O-bank configurations. The verified search data establishes candidate package and speed similarities, but it does not provide a complete pin-function cross-reference.
Use short, referenced routes for programming and clock signals, and avoid routing high-speed edges adjacent to sensitive state or feedback inputs. Add series termination where source-sink loading, ringing, or ringing-prone board geometry is observed. The listed 227 MHz is a device-class maximum, so the actual implementation should be constrained with a margin based on the slowest configured logic path, external delay, skew, and I/O loading.
Preserve the original 48-pin TQFP land pattern, pin-one orientation, exposed or no exposed pad configuration, and solder-paste pattern. A footprint named TQFP-48 does not guarantee compatibility across families with different pad dimensions or thermal-pad arrangements. For an existing assembly, inspect the board and package rather than relying on the generic package name, and confirm component height and lead geometry against the manufacturer mechanical drawing.
Confirm the exact core and I/O supply arrangement before powering an assembled board. The source lists 3.3 V, 2.5 V, and 1.8 V operation, but those values describe supported configurations rather than permission to apply all three simultaneously or to use them on every bank. Review the manufacturer power architecture, decoupling requirements, startup sequence, and programming voltage before connecting the device to legacy circuitry.
合规信息
The supplied distributor snippets mention RoHS and REACH in generic comparison content, but they do not provide a verified status for the target. Compliance fields are therefore unknown. AEC-Q100 status is also unknown because no qualification statement was supplied.
