The -7 speed grade offers 5 ns propagation delay, making the device suitable for deterministic glue-logic, control, interface, and signal-conditioning implementations. A CPLD, or complex programmable logic device, is a user-programmable semiconductor that combines programmable logic blocks, programmable interconnect, and I/O resources into a compact logic platform. The CPLD category belongs to programmable logic devices and sits below FPGA & CPLD in the broader integrated-circuit hierarchy. Unlike fixed-function logic, a CPLD allows designers to implement multiple digital functions in one device and revise the configuration during development. The XC9536XL uses two 54V18 function blocks and provides 36 macro cells with 800 usable gates. Its 3.3 V operating supply, 125 MHz maximum frequency, and 5 ns propagation delay support high-speed control logic where deterministic response and compact integration are important. The device also uses 0.35 μm CMOS technology and provides 36 I/O resources in its 48-terminal CSBGA package. This architecture is intended for communications and computing systems where compact logic consolidation can reduce component count and board area. Each macro cell supports programmable combinational or registered logic, while the embedded programmable interconnect routes signals among function blocks and I/O pins. This makes the XC9536XL suitable for implementing address decoding, control sequencing, state machines, bus arbitration, data routing, and peripheral-interface logic in a single programmable device. Typical uses include communications equipment, embedded control systems, industrial automation modules, test equipment, and computer peripheral interfaces. A design can place several small gate-level functions into one XC9536XL rather than using separate AND, OR, counter, or latch packages. Because the device is nonvolatile and programmable, logic revisions can also reduce assembly changes when interfaces evolve. The primary design consideration is PCB layout around the 48-pin CSBGA footprint and verification of the pin assignment against the selected CS package variant. Engineers should also confirm the -7 timing grade, industrial-temperature requirement, and 3.3 V interface conditions against the system timing budget. Because a CPLD is not an FPGA, designs requiring large on-chip memories, soft processors, or very high logic density should use an appropriate FPGA architecture instead. This product page combines the AMD XC9536XL device characteristics, package details, and drop-in family options with practical guidance for timing, PCB implementation, and replacement planning. It also distinguishes exact package and temperature-grade changes from speed-grade changes that may require timing revalidation.

XC9572-15PC44C - 72-Macrocell 5V CPLD | AMD PLCC
The AMD XC9572-15PC44C is a 72-macrocell in-system programmable complex programmable logic device with 34 user I/O pins, approximately 1,600 gates, and a 15 ns speed grade in a 44-pin PLCC package. It operates from a 4.75 V to 5.25 V internal supply and is based on Advanced CMOS 5 V FastFLASH technology. A CPLD is a programmable-logic semiconductor that combines a structured array of logic macrocells with a nonvolatile configuration memory. In the hierarchy of programmable devices, a CPLD sits between simple programmable logic arrays and more complex FPGAs: unlike mask-programmed logic, it can be configured after manufacture, while unlike most FPGAs it typically provides predictable routing and timing across its macrocell architecture. This makes the XC9500 family useful for consolidating fixed control, interface, and glue logic into one package. The XC9572 provides four logic-element blocks, 72 macrocells, and 34 user I/O pins. Its -15 designation corresponds to a 15 ns maximum propagation-delay class, while the product data also identifies the family as supporting parallel programming of multiple XC9500 devices. In-system programmability permits configuration through the same board connectors used by the finished system, reducing assembly work compared with separately programmed nonvolatile memory. Advanced CMOS 5 V FastFLASH technology stores the configuration nonvolatily and supports at least 10,000 program/erase cycles according to the retrieved specifications. The 5 V supply requirement and 44-pin J-lead PLCC construction distinguish this device from modern low-voltage, fine-pitch FPGA packages. That package is intended for legacy and maintenance-oriented industrial hardware rather than new compact portable products. Typical uses include industrial control logic, legacy interface adapters, programmable test fixtures, and board-level control systems where 34 I/O pins and deterministic logic blocks are more useful than a large general-purpose FPGA. Existing XC9500 designs can also retain the same configuration ecosystem while reducing the number of separate logic devices. The primary design consideration is package and supply continuity. The 44-pin PLCC footprint is not a modern board-standard land pattern, and the XC9500 family is legacy technology that is not recommended for new hardware designs. Engineers should preserve the existing footprint, verify timing at the required voltage and temperature, and plan configuration-cable, programming-software, and obsolescence continuity before committing to production quantities. This page consolidates the verified device specifications, manufacturer datasheet identity, distributor availability links, legacy-family context, and qualified drop-in comparison points so engineers can distinguish genuine replacements from parts that merely share the broad CPLD category.

Xilinx Inc. XC9572-15PC44I is an Advanced CMOS 5 V Fast FLASH in-system programmable CPLD with 72 macrocells, 34 I/O lines, and a 15 ns speed grade in a 44-LCC J-lead package. The device supports parallel programming of multiple XC9500 devices and is specified for industrial-temperature operation. According to the manufacturer data sheet, the XC9500 family provides 5 ns pin-to-pin logic delays and counting frequencies up to 125 MHz across its available density and speed grades. A CPLD, or complex programmable logic device, is a user-programmable semiconductor that combines programmable logic structures with configuration memory. Within the programmable-logic hierarchy, a CPLD sits between simple programmable logic arrays and higher-capacity FPGAs. The XC9500 family uses Fast FLASH architecture to retain configuration data and support in-system programming, allowing logic designs to be loaded or updated without removing the device from a circuit. The XC9572-15PC44I provides 72 macrocells and 34 I/O lines, making it suitable for consolidating control logic, interface adaptation, state machines, and fixed protocol functions. Its 15 ns speed designation identifies the timing grade, while the family-level 5 ns pin-to-pin delay provides a basis for high-speed signal-path implementation. Fast FLASH technology and parallel programming support also simplify multi-device configuration or manufacturing workflows. The XC9500 architecture is organized around macrocells connected through a programmable switch matrix. Each I/O can be assigned appropriate logic or I/O functions, allowing a single device to replace multiple conventional logic devices. Because configuration is nonvolatile, the programmed behavior remains available after power is removed without requiring configuration SRAM to be refreshed by an external controller. Typical applications include industrial control logic, instrumentation, communications interface logic, test equipment, embedded systems, and legacy peripheral expansion. The industrial temperature grade is appropriate for controlled industrial equipment, while the 44-LCC package offers a through-hole-compatible option for systems assembled with leaded components rather than fine-pitch surface-mount packages. When replacing this CPLD, verify the package pinout, macrocell density, I/O voltage, temperature grade, and timing grade before substitution. Faster speed-grade variants may provide timing margin, but they can change power characteristics and should not be assumed equivalent without design-level timing review. This page consolidates verified manufacturer specifications, distributor availability, same-family drop-in candidates, pricing status, pinout availability, and practical replacement guidance. It separates confirmed XC9572-15PC44I data from family-level limits and identifies missing commercial and mechanical details rather than estimating them.

The device uses 0.5 µm Advanced CMOS technology and supports 5 ns pin-to-pin logic delays, making it suitable for general-purpose logic integration, industrial automation, telecommunications infrastructure, and consumer electronics. 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.

The XC9572-7PC84C is identified as a commercial-grade 84-terminal J-bend device in an 84-lead LCC package. The -7 speed designation corresponds to the verified 7.5 ns pin-to-pin delay, while the C suffix denotes the commercial ordering variant. Because this is a 5 V architecture, system designers must verify every attached signal against the device's input thresholds and supply requirements rather than treating it as a modern 3.3 V or 1.8 V CPLD. Typical applications include industrial control systems, legacy peripheral interfaces, programmable logic replacement, instrumentation, and compact control boards requiring nonvolatile logic with in-system reconfiguration. It is especially relevant where a small amount of moderate logic must be consolidated without moving the design to a larger FPGA. Its 84-lead PLCC footprint also supports migration among compatible XC9500 devices when macrocell count, timing, and pin assignment remain acceptable. The principal design consideration is compatibility with the original XC9500 implementation. Engineers should preserve the target's power architecture, verify every pin against the XC9572 package data, and confirm that the design meets the 7.5 ns timing requirement. The XC9572 is identified as RoHS non-compliant and contains lead, so new regulated production designs should require an explicit lifecycle and environmental review before procurement. This page consolidates verified manufacturer and distributor information, drop-in same-family options, parameter comparisons, and practical migration guidance. The alternatives and application passages are intentionally limited to package-compatible XC9500-family choices supported by the supplied evidence, avoiding unrelated FPGA replacements that would require redesign.

The combination of 72 I/O and a 100-pin surface-mount package allows substantial signal connectivity without moving to a larger programmable-logic device. When designing around this device, retain the original XC9500 schematic, package, and timing constraints rather than treating newer CPLD families as direct replacements. Verify every supply rail, termination input, and pin assignment against DS065. Because the device is listed as obsolete, long-lived programs should evaluate an approved migration path before releasing new production quantities. This page organizes the obsolete-status notice, package details, programming characteristics, pin-compatible options, and practical replacement considerations. It also distinguishes same-footprint candidates from alternatives with different voltage architectures, helping engineers evaluate board reuse without overlooking configuration, timing, and lifecycle constraints.
XC9572XL - 3.3V 72-Macrocell CPLD 5ns | Xilinx AMD
The Xilinx (now AMD) XC9572XL is a 3.3V high-performance CPLD (Complex Programmable Logic Device) providing 1,600 usable gates, 72 macrocells, and a worst-case pin-to-pin propagation delay of 5 ns, housed in low-profile VQFP packages such as the 44-pin VQ44 and 64-pin VQ64. A CPLD is a type of programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy. Unlike FPGAs, which use look-up tables and volatile configuration memory, CPLDs use macrocell-based sum-of-products architecture with nonvolatile program storage, delivering deterministic, pin-to-pin timing and instant-on operation at power-up. This makes CPLDs the workhorse choice for glue logic, bus interfacing, and power-sequencing control in embedded systems. The XC9572XL is comprised of four 54V18 Function Blocks, each containing 18 macrocells. Key features include 3.3V core operation targeted at high-performance, low-voltage applications in leading-edge communications and computing systems; industry-leading pin-locking capability through a switch matrix that routes flexibly; and multiple speed grades (-5, -7, -10) so designers can trade speed against cost. Individual output enables and slew-rate-limited outputs ease 3.3V bus interfacing. Architecturally, every macrocell is a registered or combinational function generator with product-term allocation, allowing dense state machines without wasting resources. Because configuration is stored in nonvolatile memory across the XC9500XL family, no external boot flash or configuration controller is required, simplifying BOM and board design compared with SRAM-based FPGAs. Typical applications include address decoding and glue logic in embedded processors, bus bridging and interfacing in communications equipment, power-up reset and sequencing control, industrial I/O expansion, and legacy system life-cycle extensions where deterministic timing matters. Design-wise, use the -5 speed grade only where the 5 ns timing is genuinely needed; the -10 grade offers the best value for most glue-logic tasks. Note that design entry requires the legacy Xilinx ISE toolchain, which no longer runs natively on modern Windows. This page synthesizes distributor pricing, drop-in alternatives across speed grades and packages, and practical design notes not found in the manufacturer datasheet DS057.
XC9572XL-10VQG64C - 72-Macrocell 10ns CPLD | AMD/Xilinx

The device targets glue-logic and bus-interface functions where deterministic timing and instant-on (in-system programmable via IEEE 1149.1 JTAG) replace discrete 74-series logic. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device whose architecture is a sea of macrocells backed by a programmable interconnect matrix. In the system hierarchy, a CPLD sits below an FPGA (typically lower density but lower power and no configuration time) and above discrete SSI/MSI gates. CPLDs are routinely used as interface bridges, address decoders, state machines, and power-up sequencers in designs that need predictable timing in a single device. Key features of the XC9572XL-10VQG64C include 72 macrocells, 1,600 usable gates, 4 ns internal timing with 10 ns pin-to-pin (tPD) at 3.3V, 34 user I/O pins (64-pin VQFP), 5V-tolerant I/O with 3.3V core, and In-System Programmable (ISP) via JTAG. The XC9500XL family uses 5V tolerant I/O on a 3.3V core for mixed-voltage board designs. The device is specified over the commercial 0C to +70C ambient range (C suffix), with an industrial -40C to +85C option available as XC9572XL-10VQG64I. Architecturally, each Function Block contains 18 macrocells, 54 product terms, and a sum term allocated from a global pool, with the IEEE 1149.1 boundary-scan chain extending across all I/O pins. Per datasheet DS057, the Fast CONNECT switch matrix provides 100% connectivity to every FB output, enabling deterministic place-and-route timing. The I/O blocks support 5V tolerant inputs, 24 mA drive, slew-rate control, and per-pin user I/O standards. Typical applications include bus-interface bridging, address decoding, power-up logic sequencing, and I/O expansion in telecom line cards, industrial controllers, and embedded computing platforms. Because of its 5V tolerant I/O on a 3.3V core, the XC9572XL-10VQG64C is well suited to legacy systems that mix 5V peripherals with 3.3V ASICs. Designers also use it as an FPGA configuration PROM companion or as a power-sequencer for multi-rail designs. When designing with this part, ensure the JTAG TMS, TCK, TDI, and TDO pins are reserved and pulled appropriately, and provide a clean VCCAUX 3.3V rail because all outputs are powered from VCCIO while the core runs from VCCINT. Verify pin-compatibility across the family when migrating density, since the XC9536XL, XC9572XL, and XC95144XL share a footprint family plan across the 44-, 64-, and 100-pin VQFP/TQFP packages. This page synthesizes distributor stock and lead-time data, pin-compatible XC9500XL alternatives, and practical glue-logic design notes not found in the manufacturer datasheet alone.

The in-system programming architecture also supports board-level configuration workflows where a programmed device must be updated without removing it from its assembled circuit. Designers should preserve the XC9500XL power architecture and decoupling strategy, leave configuration and test behavior consistent with the AMD DS057 data sheet, and verify every external interface against the selected package pinout. Device selection also requires checking tool-chain compatibility because this established CPLD family is normally programmed with AMD/Xilinx CPLD development tools and appropriate JTAG programming hardware. This product page combines the AMD family architecture, verified family variants, pin-compatible alternatives, application guidance, and practical implementation considerations in one engineering-focused reference. It supports faster device identification while highlighting the speed-grade and temperature-grade distinctions that can affect an existing design.

FPGAs (Field-Programmable Gate Arrays) are programmable logic devices containing large arrays of configurable logic blocks (CLBs), block RAM (BRAM), DSP slices, high-speed transceiver tiles (GTX/GTH), and clock-management tiles (CMTs/PLLs/MMCMs). The Kintex UltraScale tier targets price/performance-sensitive applications such as 100G optical line cards, software-defined radio, and high-end DSP prototyping. Key headline specifications include 1,700 Configurable Logic Blocks (CLBs) and 444,343 logic cells in some datasheet groupings (the modern nominal figure is 355,474), up to 19.45 Mbits of distributed + block RAM, 312 user I/Os in the FBVA676 package, and 16.3G transceivers (per UltraScale family documentation). The device integrates 20 CMT clock tiles and 240 DSP slices, providing substantial arithmetic throughput and flexible clocking. Architecturally, the Kintex UltraScale uses the UltraScale routing fabric with stacked 3D silicon interposer-style back-bias routing, supporting up to 16.3 Gb/s transceivers for chip-to-chip and backplane SERDES. The 20 nm node and monolithic die deliver higher performance-per-watt than prior 28 nm 7-series Kintex devices while maintaining PCIe Gen3 hard-IP blocks. Typical applications for the XCKU035-2FBVA676E include 100G Ethernet bridge/router line cards, software-defined radio baseband cards, ASIC prototyping with 100% RTL mapping, high-end video processing, and DSP front-end for radar/medical imaging. The wide logic/memory/transceiver budget makes it the typical "starting point" for ADC-DAC-coupled signal-processing cards. When designing with the XCKU035-2FBVA676E, ensure multi-rail decoupling per the AMD UltraScale PCB Design Guide (UG583) for power-rail sequencing. The industrial temperature screen (E) allows deployment in outdoor telecom and industrial-control applications beyond commercial grade.
