It is supplied in an 84-terminal PLCC-style package identified by the PC84 ordering code and is based on the XC9500 5 V CPLD family. A CPLD is a programmable logic device that combines interconnected macrocells, nonvolatile configuration storage, and user-programmable I/O in a single integrated circuit. The XC9500 family sits within the broader hierarchy of programmable logic devices, alongside FPGAs and other CPLDs, and is intended for designs requiring deterministic logic implementation, in-system reconfiguration, and 5 V compatibility. The XC95108 provides 108 macrocells with 2,400 usable gates according to the verified product listing. Its 69 I/O positions support mixed interface logic, while the -7 speed grade is identified by a 7.5 ns pin-to-pin delay and a maximum fCNT of 125 MHz. In-system programming supports at least 10,000 program or erase cycles, making the device useful where field updates or configuration changes are required. Internally, the device uses advanced CMOS 5 V Fast FLASH technology, and multiple XC9500 devices can be programmed in parallel. This architecture retains configuration in nonvolatile memory, allowing the logic design to persist without a separate external configuration PROM. Parallel programming can shorten production or system-level programming time when several devices operate together. Typical uses include industrial control logic, legacy peripheral interfacing, glue logic, data-routing networks, embedded sequencing, and board-level design consolidation. Its 69 available I/O pins are particularly useful when a design needs numerous control signals but does not justify a larger programmable-logic device. The 5 V environment also supports systems that retain legacy interface voltage requirements. When planning a board, verify the PC84 footprint, programming signals, supply requirements, and I/O-standard compatibility against the manufacturer datasheet. Because this family uses a nonstandard 5 V architecture and a legacy PLCC-style package, verify availability, lifecycle status, and intended obsolescence-management plans before starting a new production design. This page combines verified manufacturer and distributor information with package-level design guidance, application analysis, lifecycle cautions, and a focused review of same-footprint speed-grade alternatives. That synthesis helps engineers distinguish a genuine PCB-compatible choice from a merely similar CPLD before committing a legacy design to replacement.
XC95108-7PC84I - 108-Macrocell 5V CPLD | AMD
The AMD XC95108-7PC84I is a 5 V in-system programmable CPLD with 108 macrocells, approximately 2,400 usable logic gates, an 83.3 MHz maximum operating frequency, and an 84-pin PLCC package. It belongs to the XC9500 family, an architecture built from eight 36V18 function blocks and supported by Advanced CMOS 5 V Fast FLASH technology. The device provides a practical combination of logic density, nonvolatile configuration storage, parallel programming, and legacy PLCC assembly compatibility. A CPLD, or complex programmable logic device, is a programmable semiconductor that combines multiple logic functions into one configurable integrated circuit. In the product hierarchy, a CPLD is a programmable logic device, a form of FPGA-related semiconductor, and a member of the broader integrated-circuit and digital-logic categories. Unlike a software-defined processor, its combinational and sequential logic behavior is established by a configuration file that remains stored in the device's FLASH memory. Key features include 108 macrocells, approximately 2,400 usable gates, 5 V operation, a 0.5 µm process, and 7.5 ns propagation delays stated in the AMD DS066 datasheet. The XC9500 family supports pin-to-pin logic delays down to 5 ns and operating frequencies up to 125 MHz across its available devices and speed grades. In-system programming and test capabilities allow configuration operations without removing the device from its assembled circuit. The XC95108 architecture divides its logic capacity into eight 36V18 function blocks. Each function block contains 18 macrocells, allowing combinational logic and registered sequential functions to be distributed across the device. This structure gives the CPLD more predictable timing than a general-purpose FPGA and makes the XC9500 architecture useful for compact glue-logic, bus-control, address-decoding, state-machine, and peripheral-interface designs. Typical applications include industrial control systems, legacy peripheral expansion, bus arbitration, data acquisition interfaces, embedded equipment, and general-purpose logic integration. The industrial-temperature suffix identifies the XC95108-7PC84I as an industrial-grade option, while its PLCC-84 package supports through-hole PCB assembly and conventional sockets. Designs must still account for the device's 5 V supply requirement and the electrical limits associated with the legacy XC9500 family. The primary design consideration is migration planning. Before replacing this CPLD with another device, engineers should compare package geometry, supply voltage, I/O standards, configuration method, macrocell resource mapping, pin assignments, and timing constraints. Similar pinouts do not necessarily guarantee that an alternative can reuse the original JEDEC configuration file without recompilation or board changes. This product record combines the verified AMD DS066 device description, distributor identifiers, and package details with practical migration guidance. It also distinguishes true same-footprint upgrade options from unrelated programmable-logic devices, helping engineers evaluate replacement risk without treating package similarity alone as proof of drop-in compatibility.

The AMD XC95144XL-10TQG100C is a 3.3 V in-system-programmable CPLD with 144 macrocells, 81 I/Os, 3,200 usable gates, 5 ns pin-to-pin logic delays, and a system frequency up to 178 MHz, housed in a 100-pin TQFP package. It is designed for high-performance, low-voltage logic integration in communications and computing systems. A CPLD, or complex programmable logic device, is a programmable semiconductor that combines reconfigurable logic fabric with nonvolatile Flash memory. It sits between simple fixed-function gates and larger FPGAs in the broader semiconductor hierarchy, providing deterministic timing, flexible logic integration, and in-system programming. The XC95144XL family uses eight 54V18 function blocks and is intended for designs requiring multiple logic functions without the complexity of a full FPGA. Key features include 144 macrocells, 81 user I/Os, 3,200 usable gates, and a 10 ns speed designation in the manufacturer part number. The supplied device data identifies a 5 ns pin-to-pin logic delay and system frequency up to 178 MHz. Its in-system programmability supports configuration updates without removing the device from the circuit, while Flash configuration storage preserves the programmed logic after power removal. The TQFP-100 package provides a surface-mount form factor for compact PCB designs. The XC95144XL architecture is organized around eight 54V18 function blocks, enabling general-purpose logic integration for communications, computing, control, and interface designs. The 3.3 V operating class and low-voltage architecture align with modern digital systems, but system designers must still verify supply tolerances, I/O standards, timing constraints, and power sequencing against the manufacturer datasheet before releasing a PCB. Typical applications include communications equipment, computing systems, industrial control logic, peripheral interfacing, signal conditioning, glue logic, and board-level control functions. The 81 I/O count provides connectivity for external buses, status signals, control lines, and programmable logic blocks. For designs requiring more I/O or higher logic density, the related XC95144XL-10TQG144I uses a different 144-pin package and should not be treated as a pin-compatible replacement. The primary design consideration is package and pinout verification. XC95144XL-10TQG100C and XC95144XL-10TQG144I are not interchangeable on a PCB because their packages and I/O counts differ. Programming must follow the AMD/Xilinx device programming procedure, and unused pins, power pins, ground pins, and configuration pins must be connected exactly as specified by the manufacturer datasheet. This page combines verified manufacturer and distributor information with practical CPLD application guidance, package-selection context, and verified cross-reference limitations. It is intended to help engineers identify the correct XC95144XL device, locate its datasheet, and distinguish true drop-in alternatives from different-package options.

The XC9500 architecture belongs to the broader CPLD, programmable-logic-device, and semiconductor hierarchies. It is intended for designs that require deterministic logic implementation, compact packaging, and the ability to retain programmed configuration without continuously supplying configuration data from external memory. The XC9536 provides 36 macrocells and approximately 800 gates for implementing combinational and registered logic. Its 10 ns speed designation indicates the maximum propagation-delay grade, while the listed 66.7 MHz operating frequency provides a useful indication of the device's performance class. The 34 user I/O pins support connections to external clocks, controls, status signals, data buses, and mixed logic functions in compact embedded systems. The device uses a 0.5 µm fabrication technology and is supplied in a surface-mount, square, 48-ball CSBGA package. Commercial-grade temperature grading is reported by the distributor data. Because this is a compact ball-grid package, PCB escape routing, via access, assembly inspection, and careful power and ground distribution are essential for reliable implementation. Typical uses include industrial control logic, interface glue, signal conditioning, bus arbitration, clocked state machines, embedded sequencing, and compact retrofit or expansion functions. The 48-CSBGA footprint is most attractive where board area is constrained and when the design team has suitable BGA assembly and inspection capabilities. When designing around the XC9536-10CS48C, verify the complete pinout, supply tolerances, I/O standards, configuration method, and timing constraints against the manufacturer datasheet before layout release. Do not infer missing I/O details from the package name or from the similar XC9536XL family. Programming-tool and bitstream compatibility must also be confirmed because the XC9500 and XC9500XL devices are architecturally different. This page consolidates verified specifications, availability references, package information, and honest drop-in-replacement analysis. It also distinguishes the directly related 7 ns speed grade from incompatible package or voltage alternatives, helping engineers make a replacement decision without assuming that a similar CPLD is electrically interchangeable.

The device is intended for commercial-temperature applications requiring compact, nonvolatile, reconfigurable logic. A CPLD is a programmable logic device that combines multiple programmable logic blocks with a fixed internal interconnect structure. Within the broader semiconductor hierarchy, the XC9536 is a complex programmable logic device, a member of the XC9500 family of FLASH PLDs, and a complement to FPGA and microcontroller solutions. Its nonvolatile configuration allows the implemented control, decoding, interface, or glue-logic functions to remain after power is removed without an external configuration memory. Key features include advanced CMOS 5 V Fast FLASH technology, support for parallel programming of multiple XC9500 devices, 34 I/O lines, and a maximum clock frequency of 66.7 MHz. The -10 speed grade identifies a 10 ns class of device, while the published family information describes 5 ns pin-to-pin logic delays. The 44-terminal commercial package provides a practical upgrade path for designs that need more I/O than smaller PLCC packages can offer. The XC9536 architecture is appropriate for deterministic logic that must be programmed and updated as a production-line or field-programmable step. Unlike a soft-core microcontroller implementation, its logic is configured directly in hardware, which can reduce firmware overhead for decoding, glue logic, control sequencing, and fixed-format interfaces. The published 0.5 µm CMOS process information identifies the device as a mature FLASH CPLD rather than a modern FPGA architecture. Typical applications include industrial control and factory automation, peripheral interface logic, legacy bus decoding, power sequencing, display and communication control, and embedded system support functions. The 5 V supply and 5 V I/O context make it especially relevant to legacy equipment where a modern low-voltage FPGA would require level-shifting or a different board revision. When designing a replacement, verify the package pinout, supported I/O voltage, timing constraints, and power architecture rather than relying only on the XC9536 family name. The verified data does not expose a complete 44-pin net assignment, so the package drawing should be checked against the manufacturer datasheet before PCB changes or cross-family substitutions are approved. This page also consolidates verified specifications, same-family alternatives, pricing context, and practical design cautions. The XC9536-10PC44C is best understood as a compact, nonvolatile, 5 V logic integration device. Its 36 macrocells, 34 I/O lines, 66.7 MHz maximum clock frequency, and 44-pin PLCC package make it suitable for moderate-complexity control and interface functions where a small FPGA would be unnecessary and a microcontroller would add firmware overhead.
XC9536-10PC44I - 36-Macrocell 10 ns CPLD | AMD | Industrial
AMD XC9536-10PC44I is a 36-macrocell, 800-gate in-system programmable CPLD with a 10 ns maximum pin-to-pin propagation delay, 34 user I/Os, and a 44-pin PLCC J-lead package.

A complex programmable logic device, or CPLD, is a configurable semiconductor that combines nonvolatile programmable logic with a structured macrocell architecture. In the broader semiconductor hierarchy, a CPLD is a programmable logic device positioned between simple fixed logic and larger FPGAs. Its deterministic timing, electrically erasable nonvolatile configuration, and in-system programmability make it useful where logic must be updated without replacing the assembled PCB. Key device features include eight 36V18 function blocks, 36 macrocells, approximately 800 usable gates, 34 I/O pins, and in-system programming with a minimum of 10,000 program or erase cycles. The -10 speed designation corresponds to a maximum propagation delay of 10.0 ns. The device also supports parallel programming of multiple XC9500 devices, simplifying board-level configuration when several related CPLDs are present. The XC9500 architecture uses product-term-based logic rather than a sea of arbitrary lookup-table and routing resources. Each macrocell can be assigned to high-performance or low-power operation, while unused product terms and macrocells can be deactivated by design software. This makes configuration tools, device pin assignment, and unused I/O treatment important parts of implementing a reliable design. Typical uses include industrial control logic, interface adaptation, legacy peripheral consolidation, data acquisition, test equipment, embedded control, and general-purpose glue logic. The 34 available I/Os provide connectivity for control signals, buses, status indicators, and programmable digital interfaces while keeping the design in a compact 44-pin surface-mount package. The principal design consideration is timing closure across every path between I/O pins and macrocell outputs. Designers should use the manufacturer's timing tools and the 10 ns device rating to analyze external setup and hold requirements, interconnects, and registered system paths. Industrial-temperature operation, programming voltage, signal levels, and unused-pin treatment must also be checked against the XC9500 family documentation. This product page consolidates verified manufacturer-family specifications, distributor availability links, package and speed-grade comparisons, and engineering guidance that are not presented together in a basic distributor listing. It also distinguishes true same-footprint alternatives from parts with similar functions but different packages or timing grades.

The Xilinx XC9536-10VQ44C is a 36-macrocell, 5 ns CPLD with 34 user I/O pins, supplied in a 44-pin VQFP package. It uses advanced CMOS 5 V Fast FLASH technology and supports in-system programming with a minimum specified endurance of 10,000 program/erase cycles. The device provides approximately 800 usable gates and a 5 ns pin-to-pin logic delay on all pins, making it suitable for general-purpose logic integration, control logic, interface bridging, and embedded system glue logic. The -10 speed grade is identified in the verified source data, while the related XC9500 family information indicates operation up to 100 MHz for this device context. A CPLD, or complex programmable logic device, is a user-programmable semiconductor positioned between fixed-function logic and larger FPGAs. Its nonvolatile configuration memory retains the programmed logic after power is removed, while its macrocell architecture implements combinational and registered Boolean functions in a compact package. The XC9500 family provides a practical bridge for designs that need more flexibility than a PAL or conventional gate array but do not require the resource density or configuration flexibility of a large FPGA. Key features of the XC9536-10VQ44C include 36 macrocells, 800 usable gates, 34 user I/O pins, 5 ns pin-to-pin logic delay, 5 V operation, and in-system programmability. The verified data also identifies support for parallel programming of multiple XC9500 devices, which can simplify production programming or board-level update procedures. The device is specified as a commercial-grade component in distributor data. The XC9536 architecture is organized around two function blocks, providing the stated 36 macrocell implementation and approximately 800 usable gates. Its nonvolatile Fast FLASH configuration allows logic to remain resident without a separate configuration PROM. For designs requiring more logic density, the related XC9500XL family supports pin-compatible migration across multiple density options in suitable package footprints, subject to careful verification of device-specific characteristics. Typical applications include industrial control and automation, peripheral interface control, data acquisition systems, communications equipment, embedded instrumentation, and legacy system refresh projects. The 34 available I/O pins allow the CPLD to combine address decoding, handshake generation, latch control, status logic, and protocol translation in one device. The 5 ns delay supports moderate-speed control paths where deterministic logic behavior is more important than high I/O throughput. Designers should verify the exact pinout, power-supply requirements, I/O voltage limits, configuration interface, and timing constraints against the manufacturer datasheet before layout. A 44-pin surface-mount footprint also requires careful land-pattern and thermal assessment. Because the verified sources identify the device as obsolete in one distributor listing, long-term production planning should confirm availability and consider a documented migration path. This product page consolidates verified distributor specifications, package information, lifecycle indications, pricing availability, and drop-in replacement research for engineers evaluating the XC9536-10VQ44C.
XC9536-10VQ44I - 36-Macrocell 5V CPLD | AMD
The AMD XC9536-10VQ44I is an 800-gate, 36-macrocell complex programmable logic device in a 44-pin VTQFP package. It supports a 4.5 V to 5.5 V internal supply range, provides 34 user I/O pins, and offers a maximum propagation delay of 10 ns. The device is based on Advanced CMOS 5V Fast FLASH technology, supports in-system programming, and can program multiple devices in parallel. Its -10 speed designation corresponds to a maximum propagation delay of 10 ns. A CPLD is a user-programmable logic device that combines a structured architecture of AND/OR logic with electrically erasable configuration memory. In the product hierarchy, the XC9536 belongs to the CPLD family of programmable logic devices, where it provides more logic capacity and I/O than simple small PLDs while retaining a relatively simple programming model. This makes it useful for consolidating glue logic, control functions, interface conditioning, and fixed digital logic into one reconfigurable device. Key features include 36 macrocells, approximately 800 gates, 34 I/O pins, 5 ns pin-to-pin logic delays for the higher-performance family context, and fCNT operation up to 125 MHz as described for the XC9500 5 V CPLD family. The in-system programming architecture supports at least 10,000 program and erase cycles. A 44-pin VTQFP package provides a surface-mount gull-wing footprint and supports conventional PCB assembly and inspection. The XC9500 architecture provides a practical migration path between speed grades and package options within the same family. The XC9536XL-10VQ44I is specifically identified as pin-compatible with the 5 V-core XC9536 in the 44-pin PLCC package, while the XC9536 family also includes PC44 and CS48 package variants. Engineers should still verify programming-file compatibility, power-up behavior, I/O standards, and timing constraints whenever moving between devices or package options. Typical uses include industrial control logic, bus interface translation, legacy peripheral emulation, programmable I/O expansion, instrumentation, and embedded system support functions. Because it is an obsolete part according to the supplied product listing, new production designs should confirm availability and lifecycle risk before committing to the XC9536-10VQ44I. When replacing the device, prioritize exact package dimensions, pin assignment, I/O voltage, supply sequencing, and supported programmer or JTAG programming chain. The -7 and -8 speed grades offer compatibility when timing is slower, but a device with a faster propagation delay should not replace one whose original design depends on a specific timing grade without margin analysis. This product data consolidates the verified family specifications, lifecycle information, package details, programming characteristics, and qualified drop-in comparisons. It also highlights where replacement decisions require timing, software, or PCB verification rather than relying only on the commercial description.
XC9536-15PC44I - 36-Macrocell 5V CPLD | Xilinx | PLCC-44
The Xilinx XC9536-15PC44I is a 36-macrocell, 5 V in-system programmable CPLD in a 44-pin PLCC package, combining an 800-gate equivalent logic capacity with a maximum pin-to-pin delay of 15 ns. Its industrial temperature rating of -40°C to +85°C and in-system programmability make it suitable for legacy control, interface, and glue-logic designs where a deterministic, non-volatile configuration architecture is required. A CPLD, or complex programmable logic device, is a programmable-logic category positioned between simple programmable logic arrays and larger FPGAs. Its architecture combines AND-array routing with programmable OR-array logic in macrocells, producing predictable propagation delays that simplify timing analysis. The XC9536 family therefore occupies the logic-hierarchy path of CPLD, programmable logic, digital semiconductor, and integrated circuit. Key attributes include 36 macrocells, an 800-gate equivalent rating, 34 user I/O pins, a 4.5 V to 5.5 V internal supply range, and a 15 ns maximum delay grade. The device uses Advanced CMOS 5 V Fast FLASH technology, retains its configuration in non-volatile memory, and supports at least 10,000 program and erase cycles. Multiple XC9500 devices can be programmed in parallel according to the family documentation. The PLCC-44 J-lead package provides 44 physical positions for 34 user I/O and dedicated power, ground, configuration, and clock-related functions. Because the exact numbered pin assignment is not reproduced in the verified excerpts, pin-level connection details must be taken from the manufacturer datasheet or the official package diagram. The device is surface-mountable but is not a leadless chip carrier and cannot be replaced by a VQFP or TQFP package without a PCB redesign. Typical applications include industrial controller glue logic, legacy peripheral interface logic, multi-copper peripheral expansion, address decoding, bus arbitration, and embedded timing control. Its 15 ns speed grade is slower than the 5 ns and 7 ns members of the XC9500 family, so designs requiring maximum operating frequency should select a faster grade if the timing budget and power requirements allow it. Designers should preserve adequate 5 V supply decoupling, route unused I/O pins according to the device guidelines, and treat the configuration, clock, and dedicated pins as non-user I/O. Because the PLCC-44 package and programmed configuration define the final interface, any substitution must be verified for package geometry, pin functions, supply voltage, macrocell capacity, and speed grade rather than function name alone. This page consolidates the verified distributor listings, family specifications, package information, and side-by-side alternatives with practical configuration and layout guidance. It also distinguishes true PLCC-44 drop-in choices from faster XC9500 devices packaged in VQFP or TQFP formats that would require a board redesign.
XC9536-15VQ44C - 36-Macrocell 15ns CPLD | Xilinx
The Xilinx XC9536-15VQ44C is an in-system programmable CPLD with 36 macrocells, 34 user I/O pins, 800 usable gates, and a 15 ns maximum pin-to-pin propagation delay, housed in a 44-pin VTQFP package. It operates from a 4.75 V to 5.25 V internal supply and uses Advanced CMOS 5V Fast FLASH technology. The device is organized as two 36V18 function blocks and supports parallel programming of multiple XC9500 devices. A CPLD, or Complex Programmable Logic Device, is a programmable logic semiconductor that sits between fixed-function logic gates and larger programmable logic arrays. Its macrocells and programmable interconnect combine deterministic timing with nonvolatile configuration memory. In the system hierarchy, the XC9500 family belongs to the CPLD and PLD class, then to programmable logic devices, integrated circuits, and semiconductors. This makes it useful for consolidating control, decoding, interface, and glue-logic functions on industrial, communications, and legacy embedded systems. The XC9536 provides 5 ns pin-to-pin logic delays for the underlying family and a maximum 15 ns propagation delay for this speed grade. It offers 34 user I/O pins, in-system programmability, and a minimum endurance of 10,000 program or erase cycles. Its 800 usable gates provide substantially more integration than individual discrete logic gates while retaining the simple tool-supported programming model associated with the XC9500 family. The XC9536 architecture uses two 36V18 function blocks, each containing 18 macrocells. Fast FLASH configuration cells retain the programmed logic without volatile SRAM, while the five-volt I/O environment supports systems designed around legacy 5 V logic families. The exact package is a 44-pin VTQFP; the verified snippets also describe the device as a square TQFP-family surface-mount package with gull-wing terminals. Typical uses include industrial control and instrumentation, legacy communications interfaces, address decoding, programmable I/O expansion, embedded system glue logic, and test equipment. The 36 macrocells are particularly effective for multi-bit decoders, state machines, control registers, bus arbiters, and compact protocol interfaces where separate logic ICs would increase component count. Designers should treat programming, 5 V supply sequencing, input overshoot, and output drive as the main implementation concerns. The verified datasheet limits external I/O voltage to VCCINT plus 4.0 V and specifies restricted transient undershoot and overshoot conditions. Before layout release, verify the selected XC9536 programmer, the legacy pinout, and all board-level signal-integrity requirements. This product record combines the verified manufacturer-family specifications, distributor availability information, package details, and same-family replacement guidance into an engineering-focused resource. It also identifies the limits of available drop-in data rather than presenting unverified cross-brand parts as direct replacements.
XC9536-5CS48C - 36-Macrocell 5 ns CPLD | AMD Xilinx
The AMD Xilinx XC9536-5CS48C is an in-system programmable complex programmable logic device with 36 macrocells, a 5.0 ns maximum propagation delay, and a commercial temperature grade. It is packaged in a 48-terminal square FBGA surface-mount package. The supplied product data identifies 800 gates, two logic elements or blocks, and an internal supply range of 4.75 V to 5.25 V. Its principal role is compact glue logic, control, decoding, interface adaptation, and other fixed-logic functions where reprogrammable nonvolatile configuration and deterministic propagation delay are useful. A CPLD is a user-programmable digital semiconductor positioned between fixed gate arrays and larger FPGAs. Its configurable macrocells and interconnect let engineers implement Boolean equations, counters, state machines, address decoding, and control logic, then retain or update the configuration in circuit. The XC9536 family belongs to the programmable-logic hierarchy that includes PLDs, complex PLDs, FPGAs, and programmable-logic semiconductors. The most important verified features are the 36 macrocells, 800 gates, 5.0 ns maximum tPD, 4.75 V to 5.25 V internal supply range, in-system programmability, and minimum 10,000 program or erase cycles. The CS48C ordering information denotes a commercial-temperature, 48-ball FBGA configuration. These characteristics make the part relevant to legacy control boards, industrial automation, communication peripherals, test equipment, and compact embedded systems where a small CPLD provides more flexibility than hardwired gates. Architecturally, the device combines programmable logic and routing resources on one integrated circuit. The reported maximum propagation delay of 5.0 ns provides a timing figure for design budgeting, but complete design timing also depends on the selected path, external loading, supply voltage, and device configuration. Designers should therefore use the manufacturer timing data and compile each design rather than treating the headline delay as a universal system latency. Typical uses include legacy bus decoding, programmable interface glue, control-logic consolidation, and in-system update of constants or logic functions. The 48-ball FBGA is appropriate for multilayer PCB layouts, but its fine-pitch balls require careful escape routing, assembly capability, and thermal consideration. The commercial grade may not be suitable where extended-temperature or automotive qualification is required; those constraints should be verified before release. The main design consideration is migration risk. CPLD configuration files, pin constraints, and JTAG programming arrangements are toolchain-sensitive, so engineers should preserve the original project, verify the exact package ball map, and test production programming. This page synthesizes the verified distributor specifications, package information, programming constraints, and practical design guidance rather than repeating a raw catalog listing. Distributor pricing and stock were not supplied as numeric values, so purchase quantities must be confirmed with the listed authorized distributors as of 2026-10-23. The verified data identifies DigiKey, Mouser, Octopart, and AMD/Xilinx listings, but does not provide a fixed unit-price ladder.
XC9536-5PC44C - 36-Macrocell 5 ns CPLD | AMD/Xilinx
The AMD/Xilinx XC9536-5PC44C is a 36-macrocell in-system-programmable CPLD with a 5 ns maximum pin-to-pin logic delay, up to 34 user I/O pins, and a 44-terminal J-lead QCCJ package. It uses 5 V Fast FLASH technology and provides 800 usable gates for general-purpose logic integration. Its internal supply-voltage range is 4.75 V to 5.25 V, and its specified counter frequency reaches 100 MHz. A CPLD is a programmable-logic device that combines macrocell-based logic with nonvolatile configuration memory. In the hierarchy, the XC9500 belongs to complex programmable logic devices, which sit between basic programmable logic devices and larger FPGAs. Its principal role is to consolidate control logic, interface logic, state machines, and fixed-function glue logic into one programmable device while retaining the device after power is removed. The XC9500 architecture described in the retrieved documentation contains two 36V18 function blocks. Key benefits include 5 ns pin-to-pin logic delays, 36 macrocells, 800 usable gates, 34 user I/O pins, and in-system programming with a minimum endurance of 10,000 program/erase cycles. It also supports parallel programming of multiple XC9500 devices, which can shorten production programming or system configuration workflows. The verified product information identifies the XC9536 as a commercial-temperature part in a square QCCJ package with J-bend terminals. Electrical limits include maximum DC undershoot below ground of either 0.5 V or 10 mA, whichever is easier to achieve. During transitions, pins may undershoot to -2.0 V or overshoot to +7.0 V for less than 10 ns when forcing current is limited to 200 mA; external I/O voltage must not exceed VCCINT by more than 4.0 V. Typical uses include industrial control, test equipment, legacy peripheral emulation, bus-interface control, and compact embedded-control logic. The 5 ns speed grade can suit deterministic control paths when system timing and I/O loading are verified, while the nonvolatile in-system programming architecture simplifies field updates and eliminates separate configuration loading after power-off. Designers should preserve the specified 5 V supply tolerance and observe the stated I/O overshoot, undershoot, and external-voltage limits. PCB layout must account for the 44 J-bend terminals, programming signals, supply decoupling, and available I/O resources. Because a CPLD pin assignment and timing design depend on the selected architecture, users should verify the complete pinout and programming requirements in the manufacturer datasheet before layout release.
XC9536-5VQ44C - 36-Macrocell 5 ns CPLD | AMD | VQFP-44
The AMD XC9536-5VQ44C is a 36-macrocell complex programmable logic device with 34 I/O pins, a 5 ns pin-to-pin logic delay, and a 44-pin VQFP package.

The XC9536 family offers 800 usable gates, 36 macrocells, and an fCNT specification of 125 MHz according to the manufacturer datasheet material supplied for this part. Key features include 5 ns pin-to-pin logic delays on all pins, 34 I/O pins, and in-system programmability for at least 10,000 program/erase cycles. Its nonvolatile FastFLASH configuration supports repeatable field updates without relying on an external configuration memory. The XC9536 is useful when a design requires more deterministic structure than a small single-chip PLD while remaining less complex than an FPGA implementation. The two function-block architecture provides 36 macrocells and 800 usable gates, with programmable interconnect supporting general-purpose logic integration. Its 125 MHz fCNT value makes the device suitable for control logic, interface adaptation, address decoding, and low-to-moderate-speed digital state-machine designs. Exact I/O standards, current limits, and recommended operating conditions should be confirmed in the complete manufacturer datasheet before production release. Typical applications include industrial control logic, legacy peripheral emulation, data-acquisition interface conditioning, and programmable test fixtures. Because the device is a nonvolatile 5 V CPLD, it is particularly useful where power-up behavior, deterministic propagation delay, and in-system reconfiguration matter more than the very high logic density of an FPGA. When laying out the PCB, preserve the manufacturer's recommended power and ground distribution, place programming interface access for production and field updates, and validate every connected I/O against the device's absolute maximum and recommended conditions. The supplied material indicates that this variant contains lead and is RoHS non-compliant, so it may not suit new designs subject to restricted-substance requirements. This page consolidates the supplied manufacturer and distributor information, identifies strict same-package drop-in candidates, and adds engineering-focused comparison and design guidance that is not normally presented together on a distributor listing.
XC9536-6PC44C - 36-Macrocell 6ns CPLD | AMD | PLCC
The AMD XC9536-6PC44C is a high-performance 5 V in-system programmable CPLD with 36 macrocells, 800 usable gates, and a 6 ns speed grade, housed in a 44-pin J-lead PLCC package. It is based on two 36V18 function blocks and supports advanced in-system programming and test capabilities for general-purpose logic integration. The device is identified by the DigiKey manufacturer listing as AMD and by legacy distribution records as Xilinx, reflecting the AMD acquisition of the original programmable-logic product line. A CPLD is a complex programmable logic device: a programmable-logic device made from interconnected macrocells and programmable interconnect resources. In the hierarchy, the XC9536 is a CPLD, a programmable logic device, a programmable-logic semiconductor, and ultimately an integrated circuit. Its nonvolatile architecture allows the programmed logic configuration to be retained, making it suitable for logic consolidation, control, address decoding, glue logic, and interface adaptation. Key features include 36 macrocells, 800 usable gates, a nominal 6 ns pin-to-pin propagation-delay class, and operation from the XC9500 5 V family. The function-block organization supports designs requiring substantially more logic than a small discrete-programmable logic device while avoiding the resource complexity of a large FPGA. The device also supports parallel programming of multiple XC9500 devices, enabling efficient board-level manufacturing and configuration workflows. The 44-terminal commercial package uses J-lead terminals and a square PLCC body identified as package code QCCJ in distributor records. Its 36V18 function-block structure provides 36 macrocells with up to 18 product-term-related resources per block as described for the XC9536 family. Programming and test features allow designers to verify and configure the device in system, reducing the need for separate programming connectors or dedicated fixture steps in suitable production architectures. Typical applications include industrial control and automation, legacy peripheral emulation, bus-interface bridging, address decoding, sequence generation, signal conditioning, and board-level glue logic. The XC9536-6PC44C is particularly appropriate when a design requires deterministic 6 ns-class logic performance, nonvolatile configuration, and a compact 44-pin PLCC footprint. Designers should treat the -6 suffix as the selected speed grade and verify timing against the exact worst-case conditions required by the system. PCB layout should reserve the programming interface, maintain appropriate supply decoupling, and preserve the manufacturer's recommended PLCC footprint and thermal design. The verified material does not provide a current manufacturer product URL, detailed electrical limits, or a complete verified pinout, so those items remain marked as data needed rather than being inferred.
XC9536-6VQ44C - 36-Macrocell 5 ns CPLD | AMD | TQFP-44
The AMD XC9536-6VQ44C is an in-system-programmable complex programmable logic device (CPLD) built with 0.5 µm Advanced CMOS 5V FastFLASH technology. It provides 36 macrocells, 800 usable gates, 34 user I/O, 5 ns pin-to-pin logic delays, and a 44-pin TQFP package. The -6 suffix denotes a 6 ns speed grade, while the final C identifies the commercial temperature grade. A CPLD is a user-programmable digital logic device that combines macrocell-based logic resources with electrically erasable nonvolatile configuration memory. It occupies the hierarchy between simple fixed-function gates and larger FPGAs. The XC9500 family is suited to general-purpose logic integration where deterministic timing, in-system programming, parallel programming of multiple devices, and compact 5 V implementation simplify board-level design. Key features include 36 macrocells, 800 usable gates, 34 I/O pins, 5 ns pin-to-pin logic delays, and 100 MHz maximum operating frequency as listed in the retrieved product data. In-system programmability supports a minimum of 10,000 program and erase cycles. Multiple XC9500 devices can be programmed in parallel, which is useful for replicated or coordinated logic sections. The family also provides advanced in-system test capabilities. The XC9536 architecture consists of two 36V18 function blocks, providing 800 usable gates and 5 ns propagation delays according to the family datasheet excerpt. Commercial-grade identification supports general industrial, instrumentation, control, interface, and legacy system designs, but the retrieved specification states that this exact order contains lead and is RoHS non-compliant. Those constraints require review before use in new lead-free procurement programs. Typical uses include industrial control logic, legacy peripheral emulation, instrumentation signal routing, board-level glue logic, and compact control systems. The 44-pin TQFP is easy to inspect and solder but is larger and has more leads than modern fine-pitch packages. System designers should account for its 5 V supply requirements, non-RoHS status, and the need to verify every unused pin and programming interface against the manufacturer datasheet. For drop-in alternatives, speed-, temperature-, and package-suffix variants in the XC9536 family must be checked against the required I/O, timing, and qualification criteria. A lower speed grade is not automatically a drop-in substitute for timing-critical designs. This page combines verified specifications, sourcing information, engineering guidance, and clearly marked data gaps rather than presenting undocumented values as guaranteed facts.
XC9536-7CS48C - 36-Macro 7.5ns CPLD | AMD Xilinx
The AMD Xilinx XC9536-7CS48C is a 36-macro complex programmable logic device with a 7.5 ns speed grade, supplied in a 48-ball CSPBGA package.

Unlike a mask-programmed fixed-function IC, a CPLD retains its configuration in nonvolatile memory, allowing the same board design to support different logic configurations. In the broader semiconductor hierarchy, XC9536-7CS48C belongs to the CPLD family, which complements FPGA and microcontroller solutions in programmable logic design. Verified distributor listings identify the device as a 36-macro CPLD with 7.5 ns timing and a 48-CSP FBGA-style package. The -7 suffix denotes the 7.5 ns speed grade, while CS48 identifies the commercial, 48-ball CSPBGA configuration. Its principal engineering value is PCB consolidation: one configurable device can replace multiple AND, OR, counter, decode, and interface components while preserving deterministic hardware timing. The CPLD architecture supports designs requiring deterministic combinational and sequential logic, such as bus arbitration, control sequencing, data routing, latch functions, and peripheral interfacing. Because the architecture differs from an FPGA, designers should evaluate macro count, I/O availability, timing requirements, pin constraints, and programming-tool compatibility before assigning signals. Typical applications include industrial automation controllers, communication interface logic, test and measurement systems, embedded control modules, legacy peripheral expansion, and general-purpose glue-logic consolidation. The commercial-grade package is useful where compact placement, nonvolatile configuration, and fast programmable logic are priorities. A critical design step is to obtain the manufacturer datasheet and pinout before layout because the 48-ball package uses a nonstandard compact BGA footprint. Validate ball assignments, supply rails, decoupling, programming access, signal integrity, and unused balls against the exact device documentation. This page combines verified catalog data with practical selection and sourcing guidance, while explicitly identifying parameters that require datasheet confirmation.

Typical applications include industrial control and automation, legacy peripheral interfacing, display and keyboard logic, communication-interface glue logic, and embedded system control. The 36-macrocell capacity is particularly useful for consolidating address decoding, latch logic, state-machine functions, and programmable I/O buffering into one nonvolatile programmable device. For new designs, engineers should also evaluate current FPGA or CPLD options when broader logic capacity, modern I/O standards, or long-term supply guarantees are required. The main design consideration is voltage compatibility. The XC9536-7PC44C is a 5 V device and is identified as RoHS non-compliant in the supplied specification record, so system-level compliance and sourcing must be reviewed before use in regulated new products. Its availability and commercial status should also be checked at purchase time because distributor listings may include legacy inventory. This page consolidates the verified technical values, source links, package information, pricing placeholders, drop-in alternatives, and design guidance for engineers evaluating the XC9536-7PC44C. Because exact pricing, current stock, pin-level details, and a manufacturer-hosted datasheet PDF were not included in the verified data, missing fields are explicitly marked rather than estimated.

Its nonvolatile FLASH configuration allows the implemented logic to remain after power is removed, eliminating separate program-memory implementation. Key features include 36 macrocells, two logic array blocks, approximately 800 programmable gates, and up to 34 I/O pins. The verified product information identifies 7.5 ns as the maximum propagation delay, while the family description reports 5 ns pin-to-pin logic delays on all pins and fCNT operation up to 125 MHz. The -7 speed designation, industrial temperature grade, and 5 V operating supply place the component in the performance and environmental class represented by XC9536-7PC44I. The 44-pin PLCC package supports through-hole board assembly and socket-based prototyping. Partstack identifies package code QCCJ, square package shape, 44 terminals, and industrial temperature grading. The verified lifecycle listing identifies the device as obsolete, so new designs should assess current platform availability and consider a redesign when long-term production support is required. Typical applications include industrial control interfaces, legacy bus and address decoding, alarm and sequencing logic, peripheral glue logic, and communication-control subsystems. The nonvolatile configuration and deterministic propagation performance are useful where control logic must restart without a separate programming cycle. When replacing this part, verify the pinout, macrocell count, supply voltage, I/O standards, timing margin, and programming file compatibility. The package identifier alone does not establish equivalence between PLCC and PQFP variants. For new 5 V designs, verify whether the obsolete XC9500 architecture remains the correct long-term choice or whether a current CPLD/FPGA platform offers better lifecycle support. This page consolidates verified distributor specifications, cross-reference candidates, lifecycle information, and package guidance to support sourcing and engineering evaluation of the XC9536-7PC44I.
