A CPLD, or Complex Programmable Logic Device, is a user-programmable digital semiconductor that combines a programmable logic array with nonvolatile configuration memory. Its position in the broader hierarchy is programmable logic → programmable logic device → CPLD → configurable logic array. Unlike a mask-programmed logic device, a CPLD can be configured after manufacture, allowing the same board design to accommodate revised logic, production testing, and field updates.
The XC9572-7PC44C provides 72 macrocells, approximately 1.6K gates, and a 5 ns speed grade. It uses FastFLASH configuration technology, supports in-system programming, and allows parallel programming of multiple XC9500 devices. The documented operating supply range is 4.75 V to 5.25 V, making the part appropriate for legacy 5 V logic systems rather than low-voltage designs operating directly from 3.3 V.
The device combines 72 dedicated macrocells with a programmable interconnect. Each macrocell can implement registered or combinational logic, while the interconnect routes signals between macrocells and package pins. A 5 ns pin-to-pin delay supports designs requiring predictable combinational timing, while the -7 speed grade corresponds to the reported 83.3 MHz maximum frequency. These figures are device-level characteristics; actual system timing must also account for external setup time, clock skew, interconnect delays, and output loading.
Typical uses include industrial control logic, telecommunications interface logic, test equipment, embedded control support, and consumer products. The 44-lead PLCC package supports surface mounting and can be useful where a socketed prototype or field replacement is desired. Its nonvolatile configuration storage allows the programmed logic to remain available after power removal without continuously rewriting the device.
Designers should verify every unused PLCC pin, programming-interface connection, supply decoupling, and I/O voltage relationship against the manufacturer datasheet. The specified internal supply range is only 4.75 V to 5.25 V. External I/O voltage must not exceed VCCINT by more than the documented 4.0 V limit, and transient overshoot and undershoot must remain within the stated absolute-maximum conditions.
This page combines verified device specifications, distributor and manufacturer source links, same-family replacement analysis, parameter comparisons, and practical CPLD design guidance. The alternatives are restricted to same-package, pin-compatible candidates; unavailable pricing, pin-level details, and certification fields are explicitly identified rather than inferred from unrelated records.

Типичное применение
XC9572-7PC44C подходит для 6 применениеs: Industrial Automation Control Logic, Telecommunications Interface Logic, Embedded Control Support Logic, Test and Measurement Instrumentation, Consumer Electronics Interface Logic, Programmable Fanout and Signal Conditioning.
Industrial Automation Control Logic
The XC9572-7PC44C fits legacy 5 V industrial control systems that require deterministic programmable logic for interlocks, signal routing, and machine sequencing. Its 72 macrocells, approximately 1.6K gates, and 5 ns pin-to-pin delay provide useful timing margin for control and decoding functions, while the 83.3 MHz maximum device frequency supports clocked state machines and interface control. FastFLASH configuration retains the programmed logic after power removal, and in-system programming permits controlled firmware or logic updates. The 44-lead PLCC package is useful for serviceable assemblies. Because no automotive or safety qualification was established, this device should be used only where the project’s qualification and availability requirements permit a legacy CPLD.
Рекомендуется
Telecommunications Interface Logic
XC9572-7PC44C is appropriate for 5 V telecommunications interface and line-card logic where programmable multiplexing, framing, and control functions are required. The 72 macrocells can implement registered data paths and control state machines, while the 5 ns pin-to-pin delay supports clocked interface logic operating below the reported 83.3 MHz device limit. Its nonvolatile FastFLASH configuration supports field logic retention, and parallel programming can shorten programming time when several XC9500 devices are configured together. The 4.75 V to 5.25 V supply requirement makes it most appropriate for established 5 V infrastructure. For new designs, verify connector timing, I/O standards, availability, and the required long-term obsolescence plan.

Embedded Control Support Logic
The XC9572-7PC44C can provide dedicated glue logic around a microcontroller in an embedded 5 V system. Its 72 macrocells are useful for protocol decoding, address decoding, interrupt expansion, and high-speed state-machine functions, while the 5 ns pin-to-pin delay helps constrain combinational paths between external devices. In-system programming permits a manufacturing fixture to configure the CPLD during board test, and FastFLASH storage eliminates a configuration upload after every power cycle. The 44-lead PLCC package also simplifies socketed prototyping. However, the 4.75 V to 5.25 V operating range and legacy lifecycle status require careful interface-level voltage compatibility checks. The design should include decoupling, defined programming access, and unused-pin treatment exactly as specified by the manufacturer datasheet.
Рекомендуется
Test and Measurement Instrumentation
XC9572-7PC44C is suitable for legacy 5 V test and measurement front ends that require flexible timing, routing, and acquisition-control logic. Its 72 macrocells and approximately 1.6K gates can implement trigger logic, counter stages, channel multiplexing, and instrument-control sequencing, while the reported 83.3 MHz maximum frequency provides ample timing margin for many instrument-control paths. The 5 ns pin-to-pin delay also benefits short combinational acquisition and trigger networks. Nonvolatile FastFLASH configuration allows repeatable operation without a separate configuration device, and the PLCC package supports prototypes and serviceable boards. Engineers must still account for analog-signal isolation, output loading, grounding, and the absolute-maximum I/O limits when connecting the CPLD to external test equipment.

Consumer Electronics Interface Logic
The XC9572-7PC44C can support programmable interface and control logic in legacy consumer products built around a 5 V bus architecture. The CPLD provides 72 macrocells for combining asynchronous inputs, generating status signals, and implementing compact state machines without a dedicated FPGA. Its 5 ns pin-to-pin delay is useful for short control paths, while FastFLASH configuration retains logic settings without a volatile boot process. The 44-lead PLCC package is available in a surface-mount form and can simplify repair or prototype assembly. Because modern consumer systems often use 1.8 V or 3.3 V signaling, the design must verify every interface voltage against the 4.75 V to 5.25 V internal supply and the permitted VCCINT-plus-4.0-V external I/O ceiling. Lifecycle procurement should be secured early.

Programmable Fanout and Signal Conditioning
XC9572-7PC44C is useful where several digital signals must be decoded, fanned out, or translated into coordinated control outputs. The 72 macrocells allow registered outputs to be distributed among multiple destinations, and the programmable interconnect reduces the need for multiple fixed gate-logic packages. A 5 ns pin-to-pin delay helps preserve timing in short combinational networks, while the 83.3 MHz maximum frequency accommodates clocked distribution functions. FastFLASH configuration allows different board variants to use the same CPLD footprint with different programmed logic, and parallel programming can reduce manufacturing test time across multiple devices. The PLCC package is well suited to prototypes, but production engineers should validate every I/O direction, termination, supply sequencing, and unused-pin connection against the package drawing and electrical specifications.

Заметки по проектированию
Design the XC9572-7PC44C as a 5 V device and operate its internal supply within the documented 4.75 V to 5.25 V range. Place the required bypass capacitors next to the PLCC power and ground pins, and route them with a short return path to avoid adding supply noise to the programmable logic. Do not interpret the permitted VCCINT-plus-4.0-V external I/O ceiling as permission to operate the core from 3.3 V. Confirm every connected signal's voltage and sequencing against the manufacturer electrical specifications before fabrication.
Keep the programming interface accessible and separate from sensitive analog or high-speed routing wherever possible. The 44-lead PLCC footprint permits short point-to-point connections to nearby logic, but programming and configuration signals still need clean references to ground. Follow the exact PLCC pin table for supply, ground, I/O, programming, and no-connect positions; the complete numbered drawing was not included in the supplied source excerpts, so do not infer pin assignments from the package orientation. Also verify mechanical compatibility, lead pitch, solderability, and whether a socket is permitted by the assembly plan.
The most common replacement error is treating every XC9572-7PC44C suffix as interchangeable. XC9572-10PC44C and XC9572-15PCG44C are slower speed grades, while XC9572XL-7PC44C is a later-generation device. A board may fit mechanically yet fail timing, programming, or mixed-voltage requirements after substitution. Before approving a replacement, compare the manufacturer pin table, timing model, supply limits, configuration behavior, macrocell architecture, and package drawing, and then run post-route static timing analysis.
The verified family specification describes 5 ns pin-to-pin logic delays, but that figure is not a substitute for a complete board-level timing calculation. Include external setup and hold requirements, clock uncertainty, output loading, and the selected interconnect path in static timing analysis. Keep high-transition-rate outputs away from sensitive inputs, use controlled return paths for programming and clock signals, and avoid relying on the nominal 83.3 MHz device frequency as a guaranteed system-clock rate without timing closure.
