XC9536-5VQ44C

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. It is designed for general-purpose logic integration and supports in-system programming with at least 10,000 program/erase cycles. The device uses Advanced CMOS 5V FastFLASH technology and can support parallel programming of multiple XC9500 devices. A CPLD, or complex programmable logic device, is a programmable logic device organized into interconnected macrocells and programmable interconnect resources. In the broader semiconductor hierarchy, a CPLD sits between basic programmable logic devices and FPGAs: it provides deterministic timing, nonvolatile configuration, and a relatively compact architecture for consolidating glue logic, control functions, state machines, and interface conditioning. 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.

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

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

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. It provides nonvolatile, in-system programmable logic for consolidating discrete glue logic into a compact configurable device. The commercial temperature grade and 48 terminals make this part suitable for compact control, interface, and system-support logic in industrial equipment. A CPLD is a programmable logic device organized around a structured logic array. 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.

XC9536-7PC44C - 36-Macrocell 5V CPLD | AMD | PLCC-44

The AMD XC9536-7PC44C is an XC9500-series complex programmable logic device (CPLD) with 36 macrocells, 34 user I/O, a nominal 5 V supply, and a 44-pin PLCC package. It provides 800 usable gates and a stated maximum clock frequency of 83.3 MHz, making it suitable for compact glue-logic, control, interface, and legacy system-integration designs. The -7 speed grade is associated with 5 ns pin-to-pin logic delays according to the available product documentation. A CPLD is a programmable logic device that combines a relatively small number of macrocells with a programmable interconnect. This places it between fixed-function logic and more complex FPGA architectures: the XC9500 family provides in-system programmability, predictable routing, and simple logic implementation for designs that do not require the capacity or routing flexibility of an FPGA. The XC9536-7PC44C also supports in-system programming with at least 10,000 program/erase cycles.

Its FastFLASH technology and support for parallel programming of multiple XC9500 devices can simplify production programming and board-level configuration workflows. The device uses Advanced CMOS 0.5 μm technology according to the supplied search records. The 44-pin J-lead PLCC package is a surface-mount package with gull-wing terminals and a square body. Compared with larger PLCC devices, the 44-pin variant balances 34 available I/O against board area. The exact pin names, voltage ratings, and programming interface details should be confirmed in the manufacturer datasheet before layout or firmware release, because those fields were not supplied in the verified data. 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.

The device supports parallel programming of multiple XC9500 devices, providing an efficient path to consolidating repetitive glue logic in industrial, communications, and legacy control systems. A CPLD, or complex programmable logic device, is a user-programmable digital integrated circuit that combines a structured logic array with nonvolatile configuration memory. Within the programmable-logic hierarchy, the XC9536 belongs to the XC9500 5 V CPLD family: a configurable-logic device within the broader FPGA and CPLD category of programmable semiconductors. 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.

XC9572-15PC44C

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.

XC9572-15PC44I - 72-Macrocell 15 ns CPLD | Xilinx

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 Advanced CMOS 5V FastFLASHTM technology, supports parallel programming of multiple XC9500 devices, and provides at least 10,000 program/erase cycles. A CPLD is a configurable logic device that combines macrocell-based programmable logic, user-programmable interconnect, and nonvolatile configuration memory. Within the product hierarchy, the XC9572-7PQ100C is a CPLD, a member of the XC9500 programmable logic family, and a 5 V logic semiconductor intended for general-purpose logic integration. Its in-system programmability permits configuration through the assembled PCB rather than requiring a separate programming operation before insertion. Key features include 72 macrocells, 72 I/O, four function blocks, 1,600 gates, and pin-to-pin logic delays specified down to 7.5 ns for this speed grade. The flexible 36V18 function block allows 90 product terms to drive any or all 18 macrocells within each block. The device also supports enhanced pin locking and programming over the full commercial voltage and temperature range. The Advanced CMOS 5V FastFLASHTM architecture provides a practical combination of nonvolatile configuration storage, predictable logic performance, and repeatable in-system programming. A system designer can use the CPLD for interface translation, control logic, bus arbitration, state-machine implementation, glue logic, and prototype logic consolidation. The 100-pin package provides more I/O than smaller XC9500 packages while retaining a conventional surface-mount form factor. Typical applications include industrial control systems, instrumentation interfaces, communications equipment, test and measurement products, and embedded control platforms. It is particularly useful when a design requires frequent field updates, nonvolatile configuration retention, or a compact replacement for multiple individually packaged logic elements. When designing around the XC9572-7PQ100C, verify the 4.75 V to 5.25 V internal supply range, respect the commercial temperature and timing limits, and confirm the exact 100-pin footprint and signal assignments against the manufacturer datasheet.

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.

XC9572XL-10VQG64C

XC9572XL-10VQG64C - 72-Macrocell 10ns CPLD | AMD/Xilinx

The AMD/Xilinx XC9572XL-10VQG64C is a 3.3V, 10ns pin-to-pin delay, 72-macrocell high-performance CPLD housed in a 64-pin VQFP (VQG64) package. It is built on the 2.5V XC9500XL family architecture, providing four 54V18 Function Blocks (FBs) that deliver 1,600 usable gates with predictable, JTAG-programmable logic and 100,000 program/erase cycles endurance. 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.

XCF02SVOG20C - 2Mb Platform Flash PROM for FPGA Config | AMD/Xilinx
XCF02SVOG20C

XCF02SVOG20C - 2Mb Platform Flash PROM for FPGA Config | AMD/Xilinx

The AMD/Xilinx XCF02SVOG20C is a 2-Mbit in-system programmable configuration PROM designed to store configuration bitstreams for Xilinx FPGAs, housed in a 20-pin TSSOP package. It provides 2,097,152 bits of NOR Flash memory organized as 2,000K x 1, operates from a 3.0V to 3.6V supply, and supports the IEEE 1149.1 / IEEE 1532 JTAG standard for in-system programming and boundary-scan testing. The device delivers guaranteed endurance of 20,000 program/erase cycles and minimum data retention of 20 years, making it suitable for long-lifecycle industrial and embedded designs. A Platform Flash PROM is a non-volatile configuration memory IC purpose-built to hold FPGA bitstreams outside the FPGA fabric. In the broader component taxonomy it belongs to NOR Flash -> non-volatile memory -> memory IC -> integrated circuit. Unlike discrete SPI Flash or parallel boot memories, Platform Flash devices integrate the JTAG programming chain, FPGA hand-shake pins (CCLK, DONE, INIT, PROGRAM) and a cascade-ready architecture, so a single IC can boot a Xilinx Spartan or Virtex FPGA without external glue logic. Key features include 2Mb density in a compact 20-TSSOP footprint, low-power advanced CMOS NOR Flash process, cascadable bitstream expansion for larger FPGAs, and JTAG boundary-scan with 3-stage registers per bidirectional pin. The industrial temperature grade (VOG suffix = -40C to +85C) and lead-free TSSOP-20 packaging make XCF02SVOG20C a mainstream choice for cost-sensitive Spartan-3 / Spartan-3A designs. The OG20C suffix denotes a TSSOP-20 package supplied in tube. From a system-level perspective, XCF02SVOG20C connects directly to the FPGA's configuration mode pins (M[2:0] = 010 selects Master Serial mode). On power-up the PROM serial-clocks the bitstream via the FPGA CCLK pin, the FPGA drives DONE high, and the PROM tri-states its data line. The bidirectional pins are observable and controllable through the JTAG boundary-scan register, which speeds prototype debug and board-level interconnect testing. The NOR Flash cell array provides fast read access with low standby current. Typical applications include Spartan-3, Spartan-3A, Spartan-3E, and Virtex-II configuration storage, industrial control boards, factory automation equipment, medical imaging FPGA platforms, and any design that requires a small-footprint non-volatile boot source for Xilinx FPGAs. Two or more XCF02S PROMs can be cascaded to support larger bitstreams for higher-density FPGAs. When designing with XCF02SVOG20C, confirm the FPGA bitstream does not exceed 2Mb before committing the BOM. AMD PCN XCN20013 (2026) confirms there is NO direct drop-in replacement for XCF02SVOG20C; design teams are advised to forecast demand and place final orders before key dates in Appendix A of that PCN, or migrate the FPGA to a newer family that boots from internal SPI Flash.

XCF04S-VO20C - 4Mb FPGA Configuration PROM, 20-TSSOP | AMD/Xilinx
XCF04S-VO20C

XCF04S-VO20C - 4Mb FPGA Configuration PROM, 20-TSSOP | AMD/Xilinx

The AMD/Xilinx XCF04S-VO20C is a 4-megabit in-system programmable Platform Flash configuration PROM designed to store configuration bitstreams for Xilinx FPGAs, packaged in a 20-pin thin shrink small outline package (TSSOP) and supplied in a tube. It operates from a 3.0 V to 3.6 V single supply, uses serial SPI-like configuration interface logic, and is rated for commercial-grade environments, making it a drop-in configuration memory solution for legacy AMD/Xilinx FPGA designs. An FPGA configuration PROM is a non-volatile flash memory device that holds the FPGA's bitstream and loads it into the FPGA's internal configuration logic at power-up. In the broader component taxonomy, the XCF04S-VO20C sits in the hierarchy: configuration memory -> PROM -> non-volatile memory -> memory IC -> semiconductor. The Platform Flash family is purpose-built for AMD/Xilinx Spartan, Virtex, and CoolRunner device chains, replacing older one-time-programmable PROMs to lower board cost and shorten programming cycles via in-system programmability through JTAG or slave-serial modes. Key features include 4 Mb of flash storage, an industrial-standard 4-pin SPI/I2C-like configuration interface, in-system programmability (ISP) via JTAG, and support for daisy-chain configuration across multiple FPGA devices or PROMs. The 20-TSSOP footprint is the same as the larger XCF08P/XCF16P family members, offering a consistent PCB layout when migrating bitstream size. Commercial temperature-grade operation and a single 3.3 V supply simplify power design versus dual-supply PROMs. From a technical standpoint, the XCF04S-VO20C is built on a NOR-flash process with an internal oscillator, command state machine, and configuration-data serializer. When the FPGA releases its DONE pin (or equivalent configuration logic), the PROM shifts out the bitstream through the dedicated data/clock pins. The flash-based design supports thousands of reprogram cycles, eliminating the need for UV-erase windows of older EPROM PROMs and reducing manufacturing rework time. The 20-TSSOP package keeps the device footprint identical to peers in the Platform Flash family. Typical applications include Spartan-3 / Spartan-6 FPGA boot-memory links, Virtex-II/Virtex-4/Virtex-5 configuration-storage companions, industrial PLCs and embedded controller boards, and legacy industrial-camera or motor-control platforms that still ship with a separate configuration PROM. It is also commonly seen in test-and-measurement prototypes where designers prefer a dedicated PROM over in-FPGA bitstream compression methods. When designing with the XCF04S-VO20C, ensure the FPGA's mode pins are set to Master Serial mode (M[2:0] = 000) so the PROM drives CCLK, and confirm the JTAG chain order in software (iMPACT, Vivado hardware manager) to avoid in-system programming conflicts. As of 2026-10-11, this part shows active distributor stock but is flagged in the AMD/Xilinx product change-notification system as approaching end of life - check PCN status before new designs.

XCF04SVOG20C - 4Mb Platform Flash Configuration PROM | AMD/Xilinx
XCF04SVOG20C

XCF04SVOG20C - 4Mb Platform Flash Configuration PROM | AMD/Xilinx

The AMD/Xilinx XCF04SVOG20C is a 4-Mbit in-system programmable Platform Flash configuration PROM designed to store and load configuration bitstreams for Xilinx FPGAs such as Spartan-6, Virtex-5, and earlier Series-6/7 devices. The device integrates 4194 kbits of non-volatile flash organized as 4000k x 1 (4-Mbit density) in a 20-pin TSSOP plastic package rated for the industrial operating range. According to AMD/Xilinx product documentation, the part supports a simple serial configuration interface (slave serial mode), daisy-chained multi-device configuration, in-system programmability via JTAG (IEEE 1149.1), and built-in data decompression that lets the PROM hold up to 8 Mbits of compressed configuration data. A Platform Flash PROM is a non-volatile configuration memory IC that boots up an FPGA by clocking out its stored bitstream at power-on. The category belongs to the broader taxonomy of FPGA configuration memories -> serial flash for FPGAs -> non-volatile boot memory -> programmable logic support ICs. Unlike generic SPI flash, Platform Flash PROMs are designed with FPGA-specific control signals (CCLK, DONE, INIT, PROGRAM) and timing compatible with Xilinx slave-serial and SelectMAP-mapped configuration protocols, which simplifies board design and removes the need to bind an MCU to load the bitstream. Key features include a low-power advanced CMOS FLASH process, IEEE 1149.1 JTAG boundary-scan and in-system programming, configurable slave serial or daisy-chain configuration modes, an internal oscillator that drives the master CCLK output, design version storage for multi-bitstream systems, and a read-protect security fuse. The PROM is specified for 3.3V core and I/O operation and is rated for an operating temperature range appropriate to industrial environments. Architecturally, the XCF04SVOG20C combines a 4-Mbit flash array with a configuration controller state machine that handles FPGA handshaking. Endurance is rated by the manufacturer at thousands of program/erase cycles, and data retention is specified in years for industrial-grade operation. The single-pin-per-bit data path makes the device pin-compatible within the Platform Flash PROM family across densities of 1 Mbit, 4 Mbit, 8 Mbit, 16 Mbit, and 32 Mbit. Typical applications include Spartan-6 and Virtex-5 FPGA configuration, FPGA-based industrial controllers that boot from non-volatile memory, test-and-measurement loaders, and any Xilinx FPGA system that requires field-updatable configuration or daisy-chained multi-FPGA configuration. Designers also use Platform Flash PROMs in safety-critical systems because the PROM's configuration validity is verified by the FPGA's CRC logic at every boot. Design consideration: when migrating an XCF04S design to a newer Xilinx configuration solution, verify the master/slave mode and DONE polarity on the PCB. Also note that the XCF04SVOG20C has been transitioned out of production by AMD/Xilinx (see lifecycle status); users with long-lived programs should plan around the suggested active alternatives listed below. This page consolidates distributor pricing, lifecycle status, drop-in alternatives, and design notes for engineers migrating off the XCF04SVOG20C, with information that goes beyond the manufacturer datasheet.

XCF16PVO48C0973 - 16Mb FPGA Configuration PROM | AMD Xilinx
XCF16PVO48C0973

XCF16PVO48C0973 - 16Mb FPGA Configuration PROM | AMD Xilinx

The AMD Xilinx XCF16PVO48C0973 is a 16-Mbit In-System Programmable Configuration PROM designed to store and stream configuration bitstreams to Xilinx FPGA families. Housed in a 48-pin TSOP (TFSOP) package, it provides a serial configuration interface optimized for Spartan, Virtex, and CoolRunner device chains. With an operating supply range of 1.65V to 2.0V and industrial-grade -40C to +85C temperature support, the part is suitable for commercial, industrial, and ruggedized embedded systems. A configuration PROM is a non-volatile serial memory that holds the FPGA bitstream and presents it to the FPGA at power-up, after reset, or on demand through JTAG/Serial-mode commands. Compared to parallel flash, configuration PROMs deliver a smaller footprint, simpler interface timing, and proven Xilinx ecosystem compatibility - making them a reference solution for legacy and current Spartan-3, Virtex-4/5, and CoolRunner-II designs that still rely on dedicated boot storage. Key features of the XCF16PVO48C0973 include 16-Mbit (16Mx1 serial organization) density, in-system programmability through the JTAG/standard Xilinx PROM programming interface, low standby current typical of serial PROMs, and a 48-TSOP package with a 0.724 inch (18.40 mm) body width. The part supports master-serial configuration modes and provides CRC-based bitstream integrity checking during FPGA load. From an architecture perspective, the device uses a serial-NOR-style command set with opcode-driven read operations, and integrates Xilinx-specific configuration flow states (e.g., 8-bit address counters, bitstream framing) that allow the FPGA to load its image directly without an external microcontroller. This eliminates boot firmware complexity in most FPGA designs. Typical applications include Spartan-3/3E/6 FPGA boot storage, Virtex-4/5 configuration backup, industrial controller FPGA subsystems, military/aerospace rad-tolerant FPGA designs (when paired with rad-hard FPGAs), and remote field-upgradeable embedded systems that need reliable in-system re-programmability over the JTAG port. When designing with this PROM, verify the FPGA-to-PROM pin mapping against the target FPGA's Master Serial configuration mode table, ensure the 1.8V rail meets PROM inrush current during read bursts, and place a 0.1 uF + bulk capacitor pair within 5 mm of the VCC pins to maintain clean read-clock edges.

XCF16PVOG48C - 16Mb FPGA Configuration PROM | AMD Xilinx | 48-TSOP
XCF16PVOG48C

XCF16PVOG48C - 16Mb FPGA Configuration PROM | AMD Xilinx | 48-TSOP

The AMD Xilinx XCF16PVOG48C is a 16-Mbit in-system programmable configuration PROM from the Platform Flash series, supplied in a 48-pin TSOP (VOG48) package and optimized for storing Xilinx FPGA configuration bit streams at 1.8V VCCINT. According to AMD/Xilinx documentation, this serial flash device is engineered for high-density FPGA bitstream storage with JTAG-based in-system programming and supports industrial temperature operation from -40C to +85C. As part of the XCFxxP family, it pairs directly with 1.8V-core Spartan-3AN, Virtex-5, and other contemporary Xilinx FPGA families for master-serial or slave-serial boot. An FPGA configuration PROM is a non-volatile memory that holds the FPGA's bitstream image so the device can self-config at power-up without an external microcontroller. The Platform Flash family sits in the hierarchy: PROM -> non-volatile memory -> configuration storage -> FPGA boot subsystem. Modern AMD/Xilinx FPGAs often embed multi-Mbit configuration storage directly on silicon, but external Platform Flash PROMs remain widely used for multi-boot images, remote field updates, and security applications where bitstream confidentiality is enforced outside the FPGA die. Key features include 16-Mbit density (twice the capacity of the XCF08P), 48-TSOP surface-mount package (0.724 inch / 18.40 mm body width), 1.65V to 2V VCCINT supply (1.8V nominal), industrial -40C to +85C operating range, JTAG IEEE 1149.1 boundary-scan and in-system programmability, and a serial configuration interface compatible with the Xilinx FPGA serial configuration bus (CCLK, DIN, DOUT, INIT, DONE). These traits allow the XCF16PVOG48C to replace the XCF08PVOG48C directly while doubling bitstream capacity for larger FPGA families or compressed bitstream storage. The device uses a serial NOR-style architecture with command-driven read/write/erase operations, organized as 16-Mbit of main memory plus a small status register for programming state. Programming and erase are managed by an internal state machine triggered over JTAG; verification uses the standard Xilinx iMPACT/iCE tools. The architecture deliberately keeps the serial interface simple so the FPGA's existing configuration controller can stream the bitstream without glue logic. Typical applications include Spartan-3AN FPGA configuration, Virtex-5 LX/SX/TX configuration, multi-boot FPGA designs, industrial control systems requiring remote in-field firmware updates, secure bitstream storage for defense and aerospace designs, and prototyping platforms where the configuration source must be field-reprogrammable without removing the FPGA from the board. When designing with this device, ensure the JTAG chain includes the PROM between TDI and TDO and that the FPGA's mode pins (M0/M1/M2) select the correct serial configuration mode. The 1.8V VCCINT must be supplied before the FPGA begins configuration; sequence accordingly to avoid partial bitstream corruption.

XCF32PVOG48C - 32Mb FPGA Config PROM 1.8V 48-TSOP | AMD

The AMD XCF32PVOG48C is a 32-Megabit in-system programmable configuration PROM for Xilinx FPGAs, supplied in a 48-pin TSOP package and operating from a 1.65 V to 2.0 V VCC supply. It is part of the Platform Flash PROM family and stores large FPGA configuration bitstreams that are loaded into Xilinx/AMD FPGAs at power-up. The XCF32PVOG48C variant specifically uses the 1.8 V Platform Flash XL family and is offered in a commercial operating temperature grade. A Platform Flash configuration PROM is a non-volatile NOR Flash memory device whose primary role is to hold the FPGA bitstream and present it to the target FPGA over a serial or parallel configuration interface. In the broader memory hierarchy it sits under EEPROM and Flash PROM, and above raw NOR Flash, providing a pre-validated, FPGA-aware configuration storage medium. It relieves the system designer of placing a separate boot Flash on the board and is typically the first device in the FPGA configuration chain. Key electrical features include a 32 Mbit (4 Mbyte) organized as 1-bit-wide serial/parallel PROM, a 1.65 V to 2.0 V operating voltage range with 3.3 V tolerant I/O pins, low-power advanced CMOS Flash technology, an in-system programmable JTAG/IEEE 1149.1 interface, and cascade support for storing larger bitstreams. The 48-pin TSOP provides a compact, surface-mount footprint compatible with standard PCB assembly lines. Architecturally, the device uses a NOR Flash core tied to a serial/parallel configuration controller, with dedicated CCLK, DIN/DOUT, and CF pins mapping directly to the FPGA configuration port. The 1.8 V internal core reduces power consumption versus 3.3 V PROMs, which is meaningful when the PROM is continuously powered alongside the FPGA. Typical applications include Xilinx Virtex and Spartan FPGA configuration boot storage, industrial control boards, communications infrastructure, and test/measurement platforms that require reliable field-upgradable bitstream storage. For military and aerospace designs, AMD also offers the XQF32PVOG48M variant in the same family. When designing with this part, ensure that the FPGA configuration mode (serial vs. parallel) and density match the bitstream size, and verify that the JTAG chain supports ISP programming of the PROM.

The device provides 312 high-performance SelectIO pins supporting multiple I/O standards including LVDS, HSTL, SSTL, and differential memory interfaces. The device also exposes 3 MMCM and 8 PLL mixed-mode clock managers for high-frequency clock synthesis and skew management. Architecturally, the Kintex UltraScale device uses UltraScale architecture enhancements over 7-series FPGAs - including new routing interconnect, more efficient clock networks, and improved block RAM and DSP resources. The 20nm planar CMOS process allows higher integration while keeping leakage power low, and the GT(GTH) transceivers support 12.5 Gb/s line rates for backplane and chip-to-chip serial interconnect. The XCKU035-1FBVA676C serves wireless baseband processing, software defined radio, high-definition video processing pipelines, high-speed serial backplane bridging, and PCIe accelerator card designs in the 100K–500K logic-cell density class.

Key features of the XCKU040-2FFVA1156I include the 20nm UltraScale architecture, which lowers total power consumption versus the previous 28nm 7-series generation, a -2 speed grade for high-performance designs, and an industrial (I-suffix) temperature rating of -40C to +100C. The 1156-ball flip-chip BGA provides 520 user I/O for high-bandwidth parallel interfaces, and the fabric includes MMCM and PLL clock management resources. On the technical side, the Kintex UltraScale family focuses on price/performance using monolithic 20nm die. The device core supply operates from 0.922V to 0.979V per the datasheet listing. The UltraScale architecture adds enhanced routing, higher DSP throughput, and improved clocking compared to Kintex-7, making the XCKU040 a popular mid-density choice between the XCKU035 and XCKU060. Typical applications include industrial image processing and machine vision, wireless baseband and RF front-end processing, medical ultrasound, and ASIC prototyping. The 520 I/O count suits multi-camera sensor aggregation and high-width data converters. Design consideration: FCBGA-1156 devices require careful PCB stackup design - escape routing under the 1.0mm ball pitch typically needs via-in-pad or at least 8 layers, and core voltage rails must meet the tight 0.922-0.979V tolerance.

Architecturally, the UltraScale+ generation introduces a register-rich silicon fabric, 3rd-generation SSI (stacked silicon interconnect) techniques, and tightly coupled DSP/BRAM columns, delivering up to 2x the performance-per-watt versus the prior generation for DSP-intensive workloads such as 5G baseband, machine-learning inference, and high-speed instrumentation. Key features of the XCKU3P include 16.375 Gbps GTH transceivers (24 channels), 6.6 Tbps serial bandwidth per device, integrated 100G Ethernet MACs, and a system-monitoring block that tracks on-die voltage and temperature. The device supports DDR4-2400 with on-chip ECC and offers hardware-rooted security via bitstream encryption and authentication using AES-256 and RSA-2048. The 676-ball FCBGA package has a body size of 27 mm × 27 mm with a 1.0 mm ball pitch, suitable for high-density PCB designs using standard BGA assembly. Typical applications span high-performance digital signal processing, 100G Ethernet network interface cards, 4K/8K video processing pipelines, test and measurement instrumentation, software-defined radio (SDR), and radar/EW front-end processing. The combination of high-speed transceivers and abundant DSP resources makes it a strong fit for low-latency, line-rate processing in both wired and wireless infrastructure. When designing with the XCKU3P-1FFVB676E, allocate at least eight PCB layers with continuous GND planes and matched-length pairs for transceivers; the package's 1.0 mm pitch requires HDI stack-ups (microvias). The extended (E) temperature grade supports -40 °C to +100 °C junction, and designers must respect the 2.0 W/cm² package thermal envelope with adequate airflow or heatsinking for sustained workloads. Vivado Design Suite is required for implementation.

XCKU5P-2FFVB676I

XCKU5P-2FFVB676I - Kintex UltraScale+ FPGA 474K LC | AMD

The AMD XCKU5P-2FFVB676I is a Kintex UltraScale+ Field Programmable Gate Array (FPGA) with 474,600 logic cells, 280 user I/Os, and 41,984,000 bits of block RAM, housed in a 676-ball FCBGA (FFVB676) package rated for the industrial temperature range. An FPGA is an integrated circuit that designers configure after manufacturing - hence field-programmable. FPGAs sit within the programmable logic device (PLD) family alongside CPLDs and form the heart of modern adaptive computing systems, providing arrays of programmable logic blocks, routing fabric, and I/O banks that enable highly parallel hardware acceleration. They are frequently used where ASIC cost or inflexibility cannot be justified. Key features of the XCKU5P include support for 725 MHz internal clocking, MMCM and PLL clock-management tiles, and core operation from 825 mV to 876 mV. The -2 speed grade balances maximum fabric performance against dynamic power, and the industrial rating (-40C to +100C junction) suits harsh deployments. Technically, the Kintex UltraScale+ family is built on a 16nm FinFET process delivering approximately 1.5x better performance-per-watt than the previous 20nm UltraScale generation. The device integrates high-speed serial transceivers, PCIe Gen3/4 hard blocks, and 100G Ethernet MAC capability, supporting high-bandwidth connectivity and partial reconfiguration for dynamic logic updates without system power-down. Typical applications include wired and wireless communications infrastructure, data center acceleration, video and image processing, and aerospace and defense systems where logic density plus low power are decisive. Designers should pay careful attention to power integrity: the 0.85 V typical core rail demands a clean, low-noise supply with dedicated power planes and extensive decoupling, and thermal dissipation under high utilization must be budgeted via the FCBGA thermal path.

XCVU9P-2FLGA2104I

XCVU9P-2FLGA2104I - Virtex UltraScale+ FPGA | AMD/Xilinx

The AMD XCVU9P-2FLGA2104I is a Virtex UltraScale+ FPGA delivering 416 user I/O, 3,911,680 Kb of block RAM capacity and 2,586,150 CLB flip-flops in a 2104-ball FCBGA (FLGA2104) package, with the -2I industrial speed grade rated for -40C to +100C operation. It targets high-performance digital designs that need massive parallel processing, on-chip memory, and high-speed serial connectivity. A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic fabric, memory, and interconnect are programmed after manufacturing. Within the semiconductor hierarchy, FPGAs sit alongside ASICs and ASSPs as core system logic devices, and the Virtex UltraScale+ family is AMD Xilinx's flagship programmable logic line for leading-edge compute, networking, and aerospace systems. Key features include the 16nm FinFET UltraScale+ fabric, the -2 speed grade optimized for high clock frequencies, and 416 package I/O for wide external buses. The device's block RAM and UltraRAM resources (up to 270 Mb UltraRAM cited in application literature) support deep buffering for packet processing and machine learning pipelines. Architecturally, the Virtex UltraScale+ family combines CLB logic, DSP48E2 slices, block RAM, UltraRAM, and GTY multi-gigabit transceivers (52 package GTY channels cited for this device) on a single die, enabling deterministic, low-latency implementations such as hardware trading paths and 5G fronthaul. The 2104-ball FCBGA packaging provides the power and signal integrity required at these data rates. Typical applications include 5G wireless baseband, data center acceleration, AI inference, and low-latency financial trading, all of which exploit the fabric's parallelism and transceiver bandwidth. Industrial and aerospace systems also use the -I industrial temperature variant for extended thermal environments. Design consideration: plan power distribution and decoupling for the multiple VCCINT/VCCO rails early, and use AMD Xilinx Vivado for synthesis and implementation - the -2I speed grade files are required for correct timing closure.
