XC2C32A-6CP56C

XC2C32A-6CP56C - 32-Macrocell 200MHz CPLD | Xilinx

Xilinx XC2C32A-6CP56C is a CoolRunner-II complex programmable logic device with 750 logic gates, 32 macrocells, 33 user I/O pins, and a maximum operating frequency of 200 MHz. It is built with 0.18 µm CMOS technology, optimized for 1.8 V systems, and supplied in a 56-ball CSP package measuring 6 x 6 mm with 0.50 mm pitch. The -6 speed designation corresponds to a listed propagation delay of 4 ns in the verified distributor specifications. A CPLD is a programmable logic device that combines nonvolatile configuration memory, programmable AND logic, and programmable OR interconnect. Within the broader semiconductor hierarchy, a CPLD is a user-programmable digital IC, complementing FPGA and ASIC technologies. The XC2C32A belongs to the CoolRunner-II family and provides deterministic logic implementation for glue logic, control, decoding, state-machine, and interface-adaptation circuits. Key device characteristics include 32 macrocells, 750 gates, 33 user I/O pins, and two logic array blocks. The verified data also reports a 4 ns propagation delay, an internal frequency of 450 MHz, CMOS logic-family construction, and a 0.18 µm CMOS process. A pin-to-pin delay as low as 3.0 ns is also listed in the component feature summary, while quiescent current is reported as low as 12 µA. The device architecture combines configurable logic with low-power 1.8 V operation. Its 32 macrocells provide moderate logic density for compact control logic rather than high-volume parallel processing. The reported 450 MHz internal frequency should not be confused with the 200 MHz maximum device operating frequency: the latter is the more conservative figure presented in the verified component specifications and is the appropriate basis for initial timing design. Typical uses include boot and power sequencing, peripheral interfacing, protocol and address decoding, industrial control logic, test-equipment control, and low-power embedded system support. The 33 user I/O pins make it useful for designs requiring moderate pin density without moving to a larger programmable-logic package. Its 56-ball CSP footprint also supports compact surface-mount assemblies when PCB-routing and assembly-process requirements are carefully observed. The primary design consideration is timing closure at the system level. Engineers should use the official AMD DS310 datasheet for pinout, bank voltage, AC timing, configuration, and absolute-maximum ratings because those details are not present in the supplied distributor excerpts. A 4 ns propagation delay supports timing-critical glue logic, but external setup, hold, skew, and routing margins still determine whether the complete interface meets its target clock. This page consolidates the verified distributor specifications, package information, sourcing data, and same-family drop-in alternatives. It also distinguishes the device's core architecture from cross-brand CPLD families that may be functionally comparable but cannot be treated as pin-compatible without an independent footprint and electrical verification.

XC2C32A-6CPG56I

XC2C32A-6CPG56I - 32-Macrocell 1.8V CPLD | AMD Xilinx

The AMD Xilinx XC2C32A-6CPG56I is a CoolRunner-II complex programmable logic device with 32 macrocells, 33 user I/Os, and a 1.8 V optimized CMOS architecture in a 56-pin CSBGA package. The device belongs to the CoolRunner-II CPLD family and combines programmable logic blocks with a fast in-system programming interface. It is specified for 0.18 µm CMOS implementation, 750 equivalent gates, and operation up to 200 MHz according to the AMD CoolRunner-II data sheet. A CPLD, or complex programmable logic device, is a user-programmable semiconductor that implements digital control, interface, and glue-logic functions. Its internal macrocells contain programmable logic functions connected by a fixed interconnect structure. The broader hierarchy is CPLD → programmable logic device → digital semiconductor. Unlike an FPGA with a large routing fabric, a CPLD generally offers more predictable timing and simpler design flows for modest logic densities, making the XC2C32A suitable for compact control and interface systems. The XC2C32A family provides 32 macrocells and 33 user I/Os. Published family information identifies fast pin-to-pin logic delays of approximately 3.0 ns to 3.8 ns and quiescent current as low as 12 µA. Its optimized architecture supports effective logic synthesis, while in-system programmability allows configuration or updates without removing the device from the circuit. These characteristics benefit low-power, 1.8 V systems where deterministic routing and compact logic capacity are more important than very high I/O density. The suffix identifies the device configuration within the CoolRunner-II product line. The “-6” denotes the performance grade, “CPG56” identifies the 56-pin CSBGA package configuration, and the trailing “I” identifies the industrial temperature option. Because the package uses a 6 mm × 6 mm body with a 0.50 mm pitch, PCB design must follow the CSBGA land pattern and account for thermal, soldering, and via-in-pad requirements specified in the AMD package documentation. Typical uses include industrial control logic, interface bridging, signal conditioning, low-power embedded control, and compact communications equipment. The 33 user I/Os can connect digital sources and destinations, while the programmable architecture consolidates functions that might otherwise require several conventional logic devices. The device is also suitable for prototypes and legacy product maintenance where an established CoolRunner-II design must be preserved. Designers should use the pin-description table and device-specific constraints in DS310 before assigning I/O standards. Power sequencing, I/O voltage compatibility, decoupling, and termination must be reviewed against the selected board voltage because the CPLD is optimized for 1.8 V systems. Programming tool compatibility and the target bitstream should also be verified before committing a design to production. This product overview combines the device architecture, package characteristics, verified ordering references, pin-compatible family alternatives, and practical design guidance. It is intended to help engineers evaluate the XC2C32A-6CPG56I for compact programmable-logic designs while distinguishing speed-grade, package, and temperature-option differences among alternatives.

XC2C32A-6PC44C

XC2C32A-6PC44C - 32-Macrocell 5.5ns CPLD | Xilinx

The Xilinx XC2C32A-6PC44C is a 32-macrocell CoolRunner-II complex programmable logic device with a nominal 5.5 ns pin-to-pin propagation delay, commercial temperature grade, and a 44-pin J-lead package. It combines a 32-cell CPLD architecture with 750 logic gates and a specified operating frequency of up to 200 MHz for compact, nonvolatile programmable-logic designs. A complex programmable logic device, or CPLD, is a user-programmable semiconductor that bridges simple programmable logic arrays and higher-capacity FPGAs. Within the hardware hierarchy, a CPLD is a programmable-logic device, a semiconductor, and a compact alternative to a small FPGA. CoolRunner-II CPLDs use nonvolatile configuration technology, allowing a circuit to retain its programmed function after power is removed without requiring continuous configuration from an external memory. Key features of the XC2C32A-6PC44C include 32 macrocells, 750 gates, a 200 MHz maximum stated operating frequency, and a 5.5 ns pin-to-pin delay. Its commercial-grade designation supports applications that do not require automotive temperature qualification. The 44-pin package also provides a practical option for laboratory prototypes, industrial control equipment, embedded interface logic, and legacy control systems where larger programmable-logic packages would be unnecessary. The device belongs to the XC2C32A portion of the CoolRunner-II family, which was designed for low-power embedded logic and offers deterministic programmable behavior. Its 32 macrocells are useful for implementing state machines, address decoding, bus arbitration, control sequencing, data routing, and peripheral glue logic. Because CPLD configuration is nonvolatile, production equipment can operate without a configuration loader after the programmed pattern has been installed. Typical applications include industrial controller interface logic, automatic test equipment, instrumentation, communications equipment, embedded motor-control sequencing, and compact consumer or communications products. The commercial speed and temperature grades make the XC2C32A-6PC44C most suitable for controlled indoor environments rather than extended industrial-temperature or automotive programs. A critical design consideration is timing closure. Engineers should use the DS310 device data sheet and the relevant CoolRunner-II implementation guidance to evaluate every external path, including setup time, hold time, clock skew, and propagation delay. Board-level signal integrity and I/O loading also matter because the package alone does not guarantee reliable operation in a completed system. This product page combines the DS310 family data with package identification, realistic same-footprint alternatives, comparison parameters, application guidance, and PCB-focused design notes. It helps distinguish speed-grade substitutions from changes that would require a different footprint or a different programmable-logic architecture.

XC2C32A-6QFG32I

XC2C32A-6QFG32I - 32-Macrocell CPLD | AMD | Industrial

AMD XC2C32A-6QFG32I is a 32-macrocell CoolRunner-II complex programmable logic device with 21 user I/O, a 1.8 V optimized architecture, and a 32-pin QFN package with an exposed pad. The -6 speed grade and industrial -I temperature designation identify this configuration for designs requiring faster logic propagation and operation across an extended industrial temperature range. A CPLD, or complex programmable logic device, is a user-programmable semiconductor used to implement fixed digital functions through configurable logic blocks and programmable interconnect. A CPLD occupies the middle ground between simple programmable logic and larger FPGAs: it combines deterministic timing, nonvolatile configuration, and relatively low power consumption with logic integration suited to control, interface, and bus-adaptation functions. The XC2C32A family uses a 0.18 µm CMOS process architecture and provides 32 macrocells for state-machine, decoder, counter, control, and bus-interface logic. According to the AMD CoolRunner-II data sheet DS310, the family is optimized for 1.8 V systems. The device also supports in-system programming and lead-free, RoHS-compliant manufacturing, making it suitable for compact industrial control and embedded equipment. Timing performance depends on the specific speed grade, system implementation, and I/O path. The -6 suffix identifies the higher-performance family option relative to slower -4 and -5 grades, while the -I suffix identifies industrial-temperature treatment. Designers should evaluate propagation delay, setup and hold requirements, clock uncertainty, and output loading against the timing requirements of the target system rather than relying only on the family-level frequency figure. Typical uses include interface glue logic, portable embedded systems, control-plane logic, bus adaptation, industrial modules, and low-power programmable board-support designs. The CPLD can consolidate reset, interrupt, level translation, address decoding, and peripheral-interface functions without the power and complexity of a larger FPGA. The principal PCB consideration is exposed-pad thermal management. Place the QFN exposed pad over a thermal-via array and connect it to the system ground plane using the manufacturer land pattern. Input and output paths also require careful signal-integrity review, particularly when external buses, clock sources, or long board-level connections terminate at the device. This technical presentation combines the manufacturer data-sheet details, package characteristics, lifecycle considerations, same-family replacement options, and practical implementation guidance needed to evaluate the XC2C32A-6QFG32I during schematic design, PCB layout, sourcing, and production qualification.

The AMD XC2C32A-6VQ44I is a 32-macro-cell CoolRunner-II complex programmable logic device built on 0.18 µm CMOS technology for 1.8 V systems and supplied in a 44-pin VTQFP package. It provides 750 logic gates, up to 33 user I/O pins, a listed internal frequency of 450 MHz, and pin-to-pin propagation delays as fast as 3.0 ns. The -6 suffix denotes the device speed grade, while the I suffix identifies the industrial-temperature option in the ordering code. A complex programmable logic device, or CPLD, is a programmable-logic semiconductor used to implement fixed digital functions without changing the physical PCB. In the broader hierarchy, a CPLD is a programmable logic device, a member of the FPGA and CPLD category, and a type of semiconductor. CoolRunner-II devices combine nonvolatile configuration storage with programmable logic blocks, allowing a loaded design to operate without an external configuration PROM after programming. Key features of the XC2C32A include 32 macro cells, approximately 750 gates, CMOS operation at 1.8 V, and low quiescent current of as low as 12 µA. Its fast pin-to-pin logic performance makes it suitable for control logic, state machines, bus arbitration, interface adaptation, and startup sequencing. The device is optimized for 1.8 V systems, helping simplify connection to modern low-voltage processors, FPGAs, and memory devices. The listed internal frequency of 450 MHz describes the device’s internal timing capability rather than a guaranteed system-clock rate. External setup, hold, interconnect, and I/O timing still determine achievable board-level performance. A listed 4 ns propagation delay applies to a characterized logic path, while 3.0 ns is the fastest stated pin-to-pin logic delay; these figures should not be treated as identical timing conditions. Typical uses include portable equipment, industrial control modules, embedded systems, and general-purpose glue logic. Its nonvolatile configuration behavior supports deterministic power-up operation, while its relatively small 32-macro-cell array is most effective when the required Boolean logic is modest and deterministic. Designers should verify every signal against the DS310 pin table, confirm the selected system voltage and I/O standards, and avoid relying on the maximum internal frequency as an unconditional peripheral operating rate. Toolchain and programming-file compatibility must also be checked before transferring an existing CPLD design to this exact ordering code. This page consolidates manufacturer and distributor information, verified source links, practical design guidance, and clearly qualified replacement analysis. It also distinguishes documented performance claims from unavailable electrical details, helping engineers make a more reliable selection without introducing unverified specifications.

A reported 323 MHz operating frequency and 3.8 ns pin-to-pin delay indicate that the device is suited to control logic, bus arbitration, interface translation, state-machine implementations, and signal conditioning. These timing figures should be evaluated against the complete design because external-device and board-level timing also affect end-to-end performance. Typical uses include industrial control, power-management sequencing, automated equipment, embedded interfaces, and general-purpose logic consolidation. The device can combine multiple fixed functions into one programmable implementation, reduce the number of separate glue-logic ICs, and allow firmware-driven configuration changes when its memory and interface requirements align with the design. PCB design should preserve a clean supply path and route configuration signals away from sensitive logic. Review the AMD DS310 pin description and recommended decoupling requirements before assigning the PCB footprint, and confirm timing against the selected I/O standard and external circuitry rather than relying on the nominal frequency alone. This product page combines the CoolRunner-II device specifications, lifecycle information, verified source links, and engineering-focused replacement guidance to support component selection, PCB planning, and legacy-design maintenance.

The AMD XC2C64A-5CP56C is a 64-macrocell CoolRunner-II complex programmable logic device with a 4.6 ns maximum pin-to-pin propagation delay, 333 MHz internal frequency, and 45 user I/O pins. It is packaged in a 56-ball CSP/LFBGA measuring 6 x 6 mm with a 0.50 mm ball pitch and is optimized for 1.8 V systems. The device is a surface-mount, in-system programmable semiconductor that consolidates programmable Boolean logic, general-purpose I/O, and dedicated resources into one package. A complex programmable logic device, or CPLD, is a user-programmable digital logic device within the broader FPGA and CPLD category. Unlike a microprocessor, which executes software instructions, a CPLD directly implements combinational and sequential logic in hardware. Its nonvolatile configuration makes it suitable for control logic, interface adaptation, bus decoding, state machines, and industrial embedded systems that must retain their configured behavior after power removal. The XC2C64A family provides 64 macrocells and four logic elements or blocks, according to the indexed manufacturer-data summary. Its 4.6 ns speed grade supports deterministic logic operation, while the 45 user I/O pins provide connections to external digital systems. The device is specified as a CMOS CPLD, uses a 1.7 V to 1.9 V internal supply range, and is optimized around low-voltage 1.8 V system design. The reported 333 MHz internal frequency is distinct from the 4.6 ns propagation-delay grade. The -5 speed designation identifies the performance grade used for timing analysis and system design. The CP56C package designation identifies a 56-terminal, 6 x 6 mm, 0.50 mm-pitch surface-mount package. In-system programmability allows a board designer to configure the device through the programming interface, while nonvolatile configuration supports repeatable startup behavior. These characteristics make the part appropriate for compact control and interface logic rather than general-purpose software processing. Typical uses include industrial controller interface logic, data-acquisition and instrumentation control, communication-interface adaptation, embedded system glue logic, and general-purpose board support functions. In these applications, the 64 macrocells can implement multiple state machines, address decoders, latch logic, and protocol converters, while the 45 user I/O pins provide interfaces to sensors, converters, memories, and other digital peripherals. The 1.8 V optimization is especially relevant for modern low-voltage system rails. PCB implementation should follow the AMD CoolRunner-II package, pinout, and board-layout documentation exactly. Because the verified source summary confirms the package dimensions and ball pitch but does not provide the complete numbered ball assignment, designers must consult DS311 before assigning power, ground, configuration, and user I/O nets. Placement should also preserve the manufacturer-specified footprint, solder-mask, paste, and thermal-relief geometry. This page combines the verified distributor specifications, the manufacturer DS311 datasheet reference, packaging details, engineering guidance, and a transparent assessment of drop-in alternatives. Unlike a distributor listing that primarily records inventory and price, it distinguishes the device's 4.6 ns speed grade, 333 MHz internal frequency, 1.8 V supply range, macrocell count, and application constraints. It also identifies where additional design data is required rather than inferring an undocumented pinout or package drawing.

Its CMOS implementation uses 0.18 µm technology and targets 1.8 V systems. Listed features include a 4.6 ns fastest pin-to-pin logic delay and low quiescent current, supporting both general-purpose embedded control and low-power portable equipment. CoolRunner-II devices use a fast, deterministic interconnect architecture for logic-intensive designs. The architecture is particularly useful where the design must combine multiple state machines, address decoding, bus control, and data-path functions in one device. The XC2C64A combines a 1.5K-equivalent logic capacity with in-system programmability, allowing a prototype to be revised without changing the PCB when the configuration interface and power architecture remain unchanged. Typical applications include industrial control interfaces, portable instrumentation, embedded system glue logic, communication protocol conditioning, and compact consumer products. Its 45 I/O pins provide sufficient connectivity for parallel data interfaces and control signals, while the small package supports space-constrained board layouts. The CPLD should be paired with a compatible configuration device or supported in-system programming arrangement when a persistent configuration file is required. The principal design considerations are correct voltage sequencing, signal compatibility across the 1.8 V core domain, and careful treatment of the CSP-56 land pattern. The 0.50 mm ball pitch requires a PCB footprint and assembly process capable of fine-pitch component placement. Confirm pin assignments, configuration pins, power pins, and I/O standards against DS311 before fabrication. This product page combines the AMD CoolRunner-II device characteristics with package guidance, verified alternative references, and practical design notes. It helps engineers identify whether the XC2C64A-5CPG56C matches a 64-macrocell, 1.8 V, fine-pitch logic design and what must be checked before PCB release or replacement sourcing.

Its 0.18 µm CMOS implementation targets compact, low-power programmable logic systems where deterministic routing and nonvolatile configuration are more important than FPGA-level capacity. A complex programmable logic device, or CPLD, is a user-programmable semiconductor within the broader programmable-logic hierarchy. It combines multiple logic macrocells, programmable interconnect, and I/O blocks into a relatively small device. Compared with a field-programmable gate array, the XC2C64A is intended for designs with moderate logic density, simpler timing analysis, and rapid in-system reconfiguration. Its CoolRunner-II architecture combines configurable logic with low-power operation for 1.8 V systems. The XC2C64A provides 64 macrocells, 45 user I/Os, a 333 MHz internal frequency, and a listed 5 ns propagation delay. Its optimized 1.8 V architecture, as fast as 4.6 ns pin-to-pin logic delays, and as low as 15 µA quiescent current make it useful in compact control, interface, and glue-logic designs. The CSBGA-56 package reduces board area but requires careful ball-layout and assembly planning. The device uses a 0.18 µm CMOS process and belongs to the CoolRunner-II product family. The 64 macrocells provide substantially more logic capacity than basic switch-mode PAL devices while retaining a comparatively simple programmable architecture. The supplied source data identifies a 333 MHz internal frequency, 45 user I/Os, a 5 ns propagation-delay listing, and the 4.6 ns pin-to-pin performance figure, making this part suitable for deterministic control logic operating from a 1.8 V supply. Typical applications include industrial control and automation, embedded interface logic, protocol conversion, bus arbitration, power sequencing, and compact communications equipment. It can also implement glue logic around processors, ASICs, or larger programmable devices. In these applications, the 64-macrocells provide enough logic capacity to consolidate small control functions, while the 45 I/Os support mixed digital connections within a space-constrained board area. The principal design consideration is package and power planning. Because the part uses a 56-ball CSP rather than a leaded package, its footprint must match the exact CSBGA land pattern, and assembly must account for ball pitch, solder mask, paste stencil, and inspection requirements. Designers should also confirm the complete pin assignment and supported I/O standards against DS311 before schematic capture; complete pin names were not included in the supplied verified excerpts. This page consolidates the supplied manufacturer and distributor information, separates documented specifications from missing data, compares same-family replacement options, and adds practical package-selection guidance. It is intended to complement, not replace, the official XC2C64A CoolRunner-II CPLD data sheet and the device configuration, timing, and package design files required for production implementation.

XC2C64A-7CP56I

XC2C64A-7CP56I - 64-Macrocell 333 MHz CPLD | AMD

AMD XC2C64A-7CP56I is a 64-macrocell CoolRunner-II complex programmable logic device with a 333 MHz internal frequency, 5 ns stated propagation delay, 45 user I/Os, and a 6 x 6 mm CSP-56 package. It is optimized for 1.8 V systems and combines in-system programmability with CMOS programmable logic in a surface-mount package. A CPLD is a programmable logic device that converts stored configuration data into digital logic functions. In the semiconductor hierarchy, a CPLD sits between basic programmable logic arrays and more complex FPGAs, combining macrocell-based logic with dedicated programmable interconnect. The CoolRunner-II family is designed for compact control, interface, glue-logic, and signal-processing designs where deterministic timing, modest logic capacity, and low system complexity are important. The device provides 64 macrocells, 4.6 ns pin-to-pin logic delays, and a maximum 6.7 ns propagation-delay specification for the -7 speed grade. Its 1.7 V to 1.9 V internal supply range targets low-voltage systems, while the quoted 15 A quiescent current and optimized 1.8 V architecture support compact, power-conscious industrial equipment. The CP-56 package supplies 56 terminals for power, configuration, control, and 45 user I/O functions. The -7 speed grade provides a practical balance between timing and component selection: it is specified at a 333 MHz internal frequency while maintaining a smaller logic delay than slower general-purpose alternatives. The A designation identifies the CoolRunner-II architecture generation, while the ordering suffix identifies package, temperature, and speed characteristics that must be checked against the manufacturer's device documentation before a design is released. Typical uses include industrial controller interface logic, data-acquisition modules, programmable glue logic, communications adapters, embedded control, and low-voltage equipment requiring in-system reconfiguration. In each case, the 64 macrocells provide enough logic density for parallel control, state-machine, and interface functions without the resource allocation and complexity of a larger FPGA. PCB design should preserve the manufacturer's recommended power and ground distribution, place bypass capacitance close to the supply pins, and route high-speed or sensitive signals with controlled impedance where applicable. Because the verified public data identifies a CSP-56 package but does not provide a complete authoritative pin table, engineers should obtain DS311 and confirm every pin, termination, and test condition before layout release or replacement qualification. This product record combines verified distributor availability, a distributor price as of 2026-10-29, same-package CoolRunner-II alternatives, and practical selection guidance. It adds engineering context around speed grade, package constraints, programming compatibility, and qualification risk without replacing the complete manufacturer datasheet.

XC2C64A-7PC44C

XC2C64A-7PC44C - 64-Macrocell 159MHz CPLD | AMD

The AMD Xilinx XC2C64A-7PC44C is a 64-macrocell CoolRunner-II complex programmable logic device with a 159 MHz performance rating, 1.8 V core supply, and a 44-pin PLCC package. It belongs to the CPLD hierarchy, combining programmable nonvolatile logic, embedded memory, and flexible I/O in a single reconfigurable device for compact control, interface, and glue-logic designs. A CPLD is a user-programmable digital logic device that combines nonvolatile configuration storage with deterministic logic structures. Unlike a mask-programmed fixed ASIC, a CPLD can be reprogrammed during development or field updates. The CoolRunner-II family also uses low-power design features and interconnected architecture to support portable equipment, industrial controls, communications equipment, and general-purpose embedded systems. The XC2C64A offers 64 macrocells for implementing combinational and sequential logic. According to the AMD CoolRunner-II XC2C64A data sheet, DS311, the device uses 0.18 µm CMOS technology and supports a 1.8 V core voltage. The -7 designation identifies the performance-grade option, while the PC44 suffix identifies the commercial-temperature 44-pin package configuration. The package is designed for surface-mount PCB assembly. The device is useful when design requirements are stable but not sufficiently large to justify an FPGA. Its macrocell-based logic and dedicated I/O structures provide a practical platform for state machines, bus arbitration, protocol bridges, keypad scanning, display control, and glue logic. Because the configuration is retained in nonvolatile memory, the implemented logic remains available after power is removed and restored. Typical implementations include industrial controller front ends, portable instrument interfaces, communications equipment, embedded control logic, and compact consumer products. Design teams can use the same 44-pin footprint for equivalent CoolRunner-II sourcing options while preserving the programmed bitstream, provided the replacement suffix and electrical conditions have been checked against DS311. Careful hardware design begins with the device pinout, power architecture, and termination requirements in DS311. Confirm all 44 package contacts, supply connections, and I/O standards on the current pin-description table before routing the PCB. Treat the configuration interface and JTAG behavior as critical design constraints because incorrect pin assignment or signal conditioning can prevent programming even when the rest of the logic is electrically correct. This page combines the device identity, manufacturer documentation, package information, sourcing references, same-footprint alternatives, and practical engineering guidance. It focuses on the decisions an engineer must make before programming or qualifying the XC2C64A-7PC44C in production equipment.

XC2C64A-7QFG48I

XC2C64A-7QFG48I - 64-Macrocell CoolRunner-II CPLD, 7ns | AMD/Xilinx

The AMD/Xilinx XC2C64A-7QFG48I is a 64-macrocell, 1.8V CoolRunner-II Complex Programmable Logic Device (CPLD) with 4.6 ns pin-to-pin propagation delay, housed in a 48-pin QFG (QFN) surface-mount package. The device belongs to the CoolRunner-II family, which combines low static power (~15 µA quiescent current) with non-volatile flash configuration memory and in-system programmability via IEEE 1149.1 JTAG. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that sits between discrete glue logic and FPGAs in the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> digital IC -> semiconductor). CoolRunner-II devices implement logic in function blocks based on PLA (Programmable Logic Array) sub-blocks with macrocell flip-flops, providing deterministic timing that simplifies design sign-off in glue-logic applications. Key features of the XC2C64A-7QFG48I include 64 macrocells organized as 4 logic blocks of 16 macrocells, 33 usable I/O pins (out of 37 total), 1.5K usable gates, a pin-to-pin delay of 4.6 ns at industrial temperature range, and DataGATE technology for per-pin input signal blocking to reduce dynamic power. The 0.18 µm CMOS process enables 1.8V core operation with I/O tolerance to 3.3V signals, simplifying interfacing with legacy 3.3V peripherals. The architecture combines a deterministic timing model with low-power 1.8V operation, making this CPLD well-suited for portable and battery-powered designs. The internal 1.8V VCCINT and I/O banked VCCIO supply rails permit mixed-voltage signaling without external level shifters, while the four global clock networks and per-macrocell OE controls give designers flexible clocking and bus-management options. Typical applications include portable/battery-powered consumer electronics where low quiescent current matters, industrial control I/O expansion and bus bridging (I2C, SPI, UART glue logic), and telecom infrastructure glue logic interfacing 3.3V peripherals to 1.8V processors. Designers also deploy this part in medical handheld devices and white goods motor control boards. When designing with this device, ensure the JTAG chain length and TDO load remain within specifications if multiple CoolRunner-II parts share one chain. The DataGATE feature can be disabled per pin to preserve dynamic behavior on critical paths; verify per-pin signal integrity when chaining long busses. This page synthesizes distributor pricing, drop-in alternative cross-references, and practical design notes not found in the manufacturer datasheet alone.

XC2C64A-7VQ100C

XC2C64A-7VQ100C - 64-Macro-Cell 1.8V CPLD | AMD

The AMD XC2C64A-7VQ100C is a 64-macro-cell CoolRunner-II complex programmable logic device operating at 1.8 V in a 100-pin VTQFP package. The device provides 1.5K logic gates, a 159 MHz internal frequency, and a 6.7 ns propagation delay, making it suitable for compact, low-voltage programmable logic designs. A CPLD is a programmable semiconductor in the FPGA & CPLD product hierarchy. Its macro cells combine programmable AND/OR logic with dedicated interconnect, allowing a design to be configured by a programming file rather than fabricated as fixed logic. Compared with an FPGA, a CPLD generally offers simpler configuration, deterministic nonvolatile configuration storage, and predictable I/O behavior, while remaining less flexible for very large, high-performance systems. The XC2C64A belongs to the enhanced CoolRunner-II family and uses 0.18 µm CMOS technology. Its 64 macro cells and 1.5K gates provide enough resources for control logic, interface adaptation, bus decoding, state machines, and glue logic. The -7 speed designation corresponds to the listed 6.7 ns propagation-delay class, while the 100-pin VTQFP package supports surface-mount assembly and offers a conventional leaded footprint for prototype and production boards. The device is optimized for 1.8 V systems and combines low power consumption with reconfigurable logic resources. In a design, the JTAG programming interface loads the configuration data, the I/O buffers interface with external signals, and the internal macro cells implement the selected Boolean functions. Because configuration is nonvolatile, the circuit can begin operating its programmed function after power is applied without requiring a separate configuration PROM. Typical uses include industrial automation, telecommunications, consumer equipment, embedded control, and general-purpose interface bridging. Its combination of 64 macro cells, 45 listed user I/Os, and a 1.8 V core suits designs that need compact glue logic but not the routing capacity of a large FPGA. It can also serve as a lifecycle upgrade for an XC2C64 design where the manufacturer identifies the enhanced XC2C64A family as pin-for-pin compatible. PCB design should preserve the 0.50 mm lead pitch and follow the manufacturer land pattern, power, decoupling, and programming guidance in DS311. Check the selected temperature grade and device variant before release because speed, temperature, and package suffix combinations define distinct orderable parts. This page combines the CoolRunner-II architecture, package characteristics, lifecycle replacement information, drop-in candidate comparison, and practical implementation guidance to help engineers evaluate the XC2C64A-7VQ100C beyond a basic distributor parameter table.

XC2C64A-7VQ100I

XC2C64A-7VQ100I - 64-Macro-Cell 1.8V CPLD | AMD Xilinx

AMD Xilinx XC2C64A-7VQ100I is a 64-macro-cell CoolRunner-II complex programmable logic device with 1.5K gates, a 1.8 V core, 0.18 µm CMOS technology, and a 100-pin VTQFP package. It operates at the -7 speed grade and is designed for compact, low-power programmable-logic implementations where deterministic routing, nonvolatile configuration, and a modest pin count are important. A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines programmable logic and programmable interconnect. In the product hierarchy, a CPLD belongs to programmable-logic devices alongside FPGAs, while its internal macro cells are constructed from CMOS logic. Compared with an FPGA, a CPLD generally offers simpler architecture and predictable timing, making it useful for control logic, interface translation, state machines, and small mixed-logic functions. The XC2C64A provides 64 macro cells and approximately 1.5K logic gates. The -7 grade corresponds to a 159 MHz system frequency in the published family specifications, while listed performance features include a 4.6 ns pin-to-pin logic delay. The device is optimized for 1.8 V systems and uses a 0.18 µm CMOS process. Its 100-pin VTQFP package supports compact surface-mount PCB construction while exposing a larger interface than smaller 44-, 48-, and 56-pin members of the family. CoolRunner-II devices combine logic implementation with nonvolatile configuration memory, allowing a circuit to retain its programmed behavior after power is removed without external configuration flash. The XC2C64A architecture is appropriate when a design needs more logic capacity than basic fixed-function gates, but not the resource density of a larger FPGA. Its performance class should be checked against the worst-case timing path in the selected design rather than inferred only from the maximum clock figure. Typical applications include industrial control interfaces, data acquisition front ends, telecommunications interface logic, instrumentation, and embedded control systems. The 64 macro cells can implement multiple state machines, bus-interface translators, protocol converters, timing blocks, or glue logic around processors. In a mixed design, the CPLD can consolidate deterministic logic between a microcontroller and external peripherals while avoiding a larger programmable-logic footprint. For PCB implementation, use the manufacturer pinout and package drawing for the 100-pin VTQFP, and confirm the available I/O count for the selected speed-grade and package combination before assigning signals. Place decoupling capacitors close to the power and ground pins, provide a clean ground reference, and route high-speed or sensitive inputs away from switching nodes. Programming should follow the CoolRunner-II toolchain and device-identification procedure described in AMD documentation. This product record combines device-family specifications, lifecycle information, obsolete-part replacement context, and same-package upgrade or replacement options. It also highlights the trade-offs among speed grade, temperature grade, package footprint, and design qualification when selecting an alternative for an existing 100-pin board.

XC2C64A-7VQ44C - 64-Macrocell 6.7ns CPLD | AMD
XC2C64A-7VQ44C

XC2C64A-7VQ44C - 64-Macrocell 6.7ns CPLD | AMD

AMD XC2C64A-7VQ44C is a CoolRunner-II complex programmable logic device with 64 macrocells, a 6.7 ns maximum propagation delay, a 1.8 V internal supply, and a 44-pin VQFP package. It is a surface-mount programmable-logic IC intended for compact embedded systems that require deterministic combinational and registered logic without the resource level of an FPGA. The part uses 0.18 µm CMOS technology and belongs to the CoolRunner-II family of CPLDs. A CPLD is a programmable-logic semiconductor that combines interconnected programmable macrocells, a fixed interconnect structure, and input/output blocks. In the product hierarchy, a CPLD is a programmable-logic device and a member of the broader FPGA and CPLD category. Compared with an FPGA, this device offers a smaller, simpler architecture intended for glue logic, control logic, interface conditioning, and modest state-machine implementations. Its 64 macrocells provide substantially more logic capacity than a simple small PLD while retaining deterministic routing and a relatively compact package. The XC2C64A-7VQ44C provides 45 user I/Os according to the retrieved DigChip specifications, 159 MHz maximum operating frequency according to the Datasheets.com listing, and a 6.7 ns maximum propagation-delay figure according to the component data sheet. The -7 speed designation is associated with the 6.7 ns class, while the 1.8 V-oriented internal supply aligns with portable and embedded equipment operating from low-voltage rails. The package is identified elsewhere in the retrieved data as a 44-pin VQFP; one secondary listing inconsistently describes a 56-pin CSP, so package-specific decisions should be confirmed against the AMD DS311 document and the individual pinout drawing. The CoolRunner-II architecture is useful for bridging asynchronous interfaces, decoding control commands, implementing compact state machines, and fixing timing or protocol issues in larger processor-based designs. Its 45 user I/Os can support multiple digital control, communication, and general-purpose I/O assignments, subject to voltage, timing, and pin constraints in the DS311 data sheet. The 6.7 ns propagation-delay class is relevant for combinational control paths, while the 159 MHz frequency figure provides an upper reference for system timing evaluation. Typical uses include industrial control, embedded processor peripherals, communication interface adaptation, data-acquisition modules, and compact control systems. Designers should avoid treating the reported frequency as a universal operating frequency because achievable performance depends on the implemented logic, routing path, I/O standard, and timing constraints. The product should be programmed as an in-system programmable CPLD using a compatible Xilinx or AMD device-programming solution. When designing a replacement PCB, verify the exact package drawings, pin names, power pins, configuration behavior, and supported I/O standards against DS311 rather than relying on distributor classification alone. Ensure the board accommodates the 44-pin VQFP footprint, exposes all required programming and power connections, and provides a stable 1.8 V internal supply environment. The retrieved YIC listing states that the offered device contains lead and is RoHS non-compliant, which may matter for new production sourcing even though the individual component is listed as active.

XC2C64A-7VQ44I

XC2C64A-7VQ44I - 64-Macrocell 1.8V CPLD | AMD Xilinx

The AMD Xilinx XC2C64A-7VQ44I is a 1.8 V CoolRunner-II complex programmable logic device containing 64 macrocells and approximately 1.5K logic gates in a 44-pin VTQFP package. Listed device characteristics include a 159 MHz speed designation, 45 user I/O pins, 5 ns propagation delay, and as-fast-as 4.6 ns pin-to-pin logic delay. The device uses 0.18 µm CMOS technology and is optimized for low-voltage, high-performance logic implementations. A CPLD is a programmable-logic device that integrates nonvolatile configuration memory, programmable interconnect, and logic blocks into one package. In the semiconductor hierarchy, the XC2C64A belongs to the CPLD class, which sits between fixed-function logic ICs and larger FPGAs. CoolRunner-II devices are commonly used where modest logic density, fast routing, low standby power, and relatively simple re-programming are more important than the capacity of a large FPGA. The XC2C64A provides four principal design advantages: 64 macrocells for compact multi-function logic, 45 user I/Os for external interfaces, 1.8 V operation for compatibility with low-voltage system rails, and a specified 7 speed grade for timing-oriented designs. Its advertised 5 ns propagation delay and 4.6 ns pin-to-pin delay support control logic, interface conditioning, bus arbitration, state-machine implementations, and low-to-moderate-complexity glue logic. Its 0.18 µm CMOS implementation places the part in the CoolRunner-II product generation. The listed 159 MHz frequency is distinct from the separately reported 333 MHz internal-frequency figure in distributor technical summaries, so designs should use the AMD DS311 data sheet for timing definitions and device-limit interpretation. Quiescent-current details are also inconsistent across the supplied summaries, making the manufacturer document the controlling source for final power-budget decisions. Typical uses include industrial control, communication equipment, battery-operated instruments, embedded system supervision, bus-interface logic, and general-purpose programmable glue logic. The 45 I/O count permits substantial board-level connectivity without moving to a larger programmable-logic device, while the 44-pin surface-mount package supports compact designs. Designers should verify the exact VQ44 pin mapping, supported I/O standards, bank voltage limits, and AC timing from DS311 before layout release. Because the available search summaries conflict between VTQFP-44 and a 56-pin CSP description, the package drawing and pinout should be checked against the device marking and ordering code rather than inferred from the MPN alone. This page combines verified distributor specifications, official AMD documentation, and engineering-focused guidance for XC2C64A-7VQ44I selection, timing review, layout validation, and drop-in replacement assessment.

XC2S50E-6PQG208C

XC2S50E-6PQG208C - Spartan-IIE FPGA, 50K Gates, 208-PQFP | AMD

The AMD (formerly Xilinx) XC2S50E-6PQG208C is a Spartan-IIE Field Programmable Gate Array (FPGA) IC integrating 50,000 system gates, 1,728 logic cells, and 32,768 bits of block RAM in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package with 146 user I/O pins. It is built on a 0.18 µm CMOS process, supports system performance beyond 200 MHz with internal logic capable of 357 MHz, and is offered in the -6 speed grade with 6 ns pin-to-pin logic delay. A Field Programmable Gate Array (FPGA) is a type of integrated circuit in the programmable logic family, sitting between standard logic ICs and ASICs in the semiconductor hierarchy. FPGAs contain an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory that can be reconfigured post-manufacture to implement arbitrary digital logic. The Spartan-IIE family targets cost-sensitive, high-volume applications requiring densities up to 600K system gates with the flexibility of in-system reprogrammability via SRAM configuration cells. Key features of the XC2S50E include SelectIO™ signaling supporting 18 popular I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and GTL; up to 384 CLBs (configurable logic blocks); four Delay-Locked Loops (DLLs) for clock de-skew and frequency synthesis; 32 kbit distributed RAM plus dedicated 4 kbit dual-port block RAM; and JTAG boundary-scan (IEEE 1149.1) for board-level testing. The device operates from a 2.5 V core supply with 1.5 V–3.3 V auxiliary supply for I/O flexibility. The Spartan-IIE architecture combines Lookup-Table (LUT) based logic, distributed SelectRAM, dedicated 18 kbit Block SelectRAM multipliers, and a hierarchical routing fabric. This combination is engineered for digital signal processing (DSP), glue logic, bus interfacing, and embedded control, replacing discrete TTL/CMOS logic while keeping unit cost low. Hot-swap I/O, 5 V tolerance on user I/O, and PCI 66 MHz compliance expand its applicability into mixed-voltage and legacy backplane designs. Typical applications include telecommunications bridging and aggregation, low-cost DSP front-ends, industrial control and instrumentation, video processing, set-top box interface logic, and embedded computing subsystems. The 208-PQFP with 1.0 mm lead pitch is well-suited for prototype and low-volume production where surface-mount reflow of fine-pitch BGA is undesirable. When designing with the XC2S50E-6PQG208C, ensure the 208-PQFP land pattern matches the 30.6 mm × 30.6 mm body dimensions and that decoupling follows the manufacturer reference schematic (typically 0.1 µF + 10 µF per supply rail). The ISE WebPACK toolchain supports this device and is recommended for synthesis, place-and-route, and bitstream generation.

XC2V1500-4FFG896C - Virtex-II 1.5M Gates FPGA | AMD/Xilinx
XC2V1500-4FFG896C

XC2V1500-4FFG896C - Virtex-II 1.5M Gates FPGA | AMD/Xilinx

The AMD (formerly Xilinx) XC2V1500-4FFG896C is a Virtex-II family Field-Programmable Gate Array (FPGA) IC integrating 1.5 million system gates, 17,280 logic cells, and 884,736 bits of block RAM in a 896-ball Flip-Chip Fine-pitch Ball Grid Array (FFG/FCBGA) package. The '4' speed grade, commercial 'C' temperature (0C to 85C), and 528 user I/O make it suitable for high-density logic prototyping, embedded processing platforms, and high-speed serial interfacing using SelectIO and RocketIO-capable I/O standards (when paired with the appropriate family member). A Field-Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reconfigure post-manufacture to implement arbitrary digital circuits, from glue logic to full processor subsystems. Within the IC hierarchy, an FPGA sits between an ASIC and a programmable logic device (PLD/CPLD): ASICs are application-specific and fixed, CPLDs handle simpler glue logic with non-volatile configuration, and FPGAs sit above for the highest logic density and highest-speed serial I/O. Virtex-II is the Xilinx generation built on a 0.15 micrometer CMOS process with 1.5V core, introducing dedicated 18x18 hardware multipliers and block RAM tiles tuned for DSP and datapath acceleration. Key parameters worth highlighting: 1.5 million system gates (a marketing-derived gate count), 17,280 logic cells, 1,920 Configurable Logic Blocks / CLBs (the 17,280-cell / 1920-LAB count matches Virtex-II datasheet convention), 884,736 bits of embedded block RAM organized into selectable 18-Kbit blocks, and 528 user I/O pins distributed across the package perimeter. The device supports configuration via SelectMAP, JTAG (IEEE 1149.1), and serial modes, with on-chip clock management through eight Digital Clock Managers (DCMs). Architecturally, Virtex-II uses a symmetrical array of CLBs each containing four slices, each slice carrying two 4-input Look-Up Tables (LUTs), dedicated carry logic for fast arithmetic, and distributed SelectRAM. The hard IP blocks of 18x18 multipliers and 18-Kbit block RAMs allow DSP and buffering functions to run at hundreds of MHz without consuming general logic resources. Typical applications include high-throughput data acquisition front-ends, telecom baseband processing (3G and early LTE line cards), broadcast video processing, avionics prototype platforms (mil/aero-grade variants exist but the -4 C grade is commercial), and ASIC prototyping shells. The 528 I/Os and large logic capacity also suit test-and-measurement backplanes. Designers should be aware that this part is now classified Obsolete (EOL) in the supply chain; long-term designs should consider Virtex-4, Virtex-5, or current Kintex 7-series equivalents from AMD/Xilinx, while PCN documentation must be reviewed for any in-production designs. Power estimation should be performed pre-layout using the Xilinx Power Estimator (XPE) because the VQFN-style multi-rail FCBGA demands a substantial decoupling network and a thermal solution capable of sustaining typical Virtex-II junction profiles.

The AMD Xilinx XC2VP7-6FF672 is a Virtex-II Pro family Field Programmable Gate Array (FPGA) built on a 0.13um/90nm dual-process CMOS technology and housed in a 672-ball flip-chip BGA (FF672) package. It delivers 11,088 logic cells, 396 user I/O, 8 RocketIO multi-gigabit transceivers, and one embedded PowerPC 405 processor core, providing a complete system-on-chip platform for high-performance embedded designs. Virtex-II Pro FPGAs belong to the Platform FPGA family, which integrates hard IP such as multi-gigabit transceivers and embedded processor cores directly onto the programmable fabric. By combining hardware-accelerated serial I/O (RocketIO at up to 3.125 Gbps) with an embedded PowerPC 405 core, these devices enable designers to replace discrete ASSPs and reduce system BOM cost while accelerating time-to-market for networking, telecom, and embedded computing applications. Key features include 1,1088 logic cells, 792 Kbit of distributed SelectRAM, dedicated 18x18 multipliers for DSP blocks, 8 RocketIO serial transceivers, 1 hard PowerPC 405 processor core running up to 400 MHz, 396 maximum user I/O, and 27mm x 27mm FF672 package with 1.0mm ball pitch. The device supports common logic families via 1.5V core supply, 2.5V/3.3V-tolerant I/O, and is available in commercial (C) and industrial (I) temperature grades. The Virtex-II Pro architecture combines a configurable logic fabric (CLBs, slices, LUTs), block RAM, multipliers, DCM clock managers, and hard IP cores. The dual-process 0.13um/90nm CMOS process enables integration of the PowerPC 405 hard core and RocketIO transceivers, providing deterministic performance that soft processor cores on the fabric cannot match. Typical applications include 10 Gigabit Ethernet line cards, software-defined radio base stations, high-speed serial backplanes, telecom multiplexer/demultiplexer equipment, and embedded computing platforms. The integrated PowerPC 405 makes the part particularly attractive for systems requiring firmware-driven control with hardware-accelerated DSP and serial I/O. When designing with the XC2VP7-6FF672, use the Xilinx ISE Design Suite for synthesis, place-and-route, and bitstream generation. Multi-gigabit serial links require careful PCB layout with controlled-impedance differential traces; consult Xilinx application note XAPP681 for RocketIO board design guidelines.

The Xilinx XC3090L-100PC84C is a 5V, 100MHz Field Programmable Gate Array from the legacy XC3000 family, housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package. It integrates approximately 6,000 usable gates and 320 Configurable Logic Blocks (CLBs) on a 5-micron CMOS process, making it one of the highest-density parts in the original XC3000 series. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of an array of configurable logic blocks, programmable interconnect, and input/output cells that engineers can program after manufacture. FPGAs sit within the broader taxonomy of programmable logic devices (PLD) and digital semiconductors, alongside CPLDs, ASICs, and microcontrollers. Unlike an ASIC (Application-Specific Integrated Circuit), an FPGA requires no photomask NRE and ships as a blank silicon canvas that the user programs via a hardware description language or schematic capture flow, then a vendor-specific bitstream. Key features of the XC3090L-100PC84C include a -100 speed grade, 144 logic-cell equivalent capability, and CMOS technology at a 5V supply. The device supports distributed RAM via CLB configuration and includes on-chip boundary-scan (IEEE 1149.1) test logic for board-level diagnostics. The PLCC-84 ceramic-compatible plastic package has a JEDEC-standard 1.27 mm pin pitch, allowing socket-mounting for prototyping or direct surface mounting for production. The XC3090L variant is the low-power evolution of the original XC3090, using a 3.3V core option in some speed grades while retaining 5V-tolerant I/O. The part is typically configured using the Xilinx XACT development environment with schematic capture, automatic place-and-route, logic and timing simulation, and an interactive design editor for design optimization. Designers should use timing calculator features and integrate with the standard design environment toolchain. Typical applications of the XC3090L-100PC84C include legacy telecommunications glue logic, industrial control state machines, prototyping ASICs, glue logic for vintage bus architectures such as VME and ISA, and educational FPGA laboratory kits. The 100MHz internal logic rate suits mid-speed glue-logic and bus-interface bridging tasks. When designing with this part, ensure adequate decoupling (one 0.1uF per supply pin cluster) and respect the 5V I/O voltage level. Note that the XC3000 family is NRND/EOL for new designs - consider Xilinx Spartan or Artix-7 for new projects unless maintaining legacy equipment. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers source or replace this legacy FPGA with confidence.

XC3090L-125PC84C - 5K-Gate FPGA, 125MHz, 84-Pin PLCC | Xilinx
XC3090L-125PC84C

XC3090L-125PC84C - 5K-Gate FPGA, 125MHz, 84-Pin PLCC | Xilinx

The Xilinx XC3090L-125PC84C is a CMOS Field Programmable Gate Array (FPGA) from the XC3000L low-voltage Logic Cell Array family, supplied in an 84-pin PLCC package. It features 320 Configurable Logic Blocks (CLBs), approximately 5000 equivalent logic gates, 928 flip-flops, and a maximum clock frequency of 125 MHz. The device operates from a 3.0 V to 3.6 V supply (typical 3.3 V), reflecting the L-suffix low-voltage variant of the classic XC3000 architecture. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of an array of configurable logic blocks, interconnect routing, and programmable I/O cells that can be electrically configured by the end user to implement arbitrary digital logic. FPGAs occupy the middle ground between fixed-function ASICs and software-programmable microcontrollers, offering parallel hardware execution, deterministic timing, and on-the-fly reconfigurability. The XC3000L family sits at the foundation of SRAM-based FPGA technology, with logical hierarchy: CLB -> logic cell array -> FPGA -> programmable logic device (PLD) -> digital integrated circuit. Key features of the XC3090L-125PC84C include 320 CLBs delivering roughly 5,000 usable gates, 928 edge-triggered flip-flops for pipelined or state-machine designs, a maximum toggle rate of 125 MHz, and 84 PLCC pins providing programmable I/O plus dedicated configuration, clock and JTAG interfaces. The device supports JTAG (IEEE 1149.1) boundary-scan for board-level test, in-system reprogrammability through the standard Xilinx XC3000 configuration bitstream, and a power-down mode that significantly reduces quiescent current for battery-friendly applications. Architecturally, the XC3090L implements the classic Xilinx XC3000 CLB with a 5-input lookup table feeding two flip-flops, a programmable interconnect matrix of single-length and double-length lines, and tri-state buffers that allow efficient implementation of muxes, busses, and tri-state I/O. The 125 MHz speed grade places it in the highest tier of the XC3090L family, enabling high-performance glue logic, custom state machines, and DSP-style bit-level pipelines on a single chip. Typical applications include legacy telecom interface glue logic, industrial control and instrumentation front ends, custom peripheral controllers for microprocessor systems, prototyping vehicles for ASIC verification, and reconfigurable test fixtures. Designers building long-life industrial equipment, military refresh programs, or replacement boards for existing XC3000-based systems remain the primary users of this classic part. Designers using the XC3090L-125PC84C should preserve the legacy 3.3 V supply rail, follow Xilinx XC3000 configuration mode recommendations (SelectMAP/serial master or slave), and respect the PLCC pin-out when laying out new PCBs or repairing legacy boards. This page combines distributor pricing, verified cross-reference data, and design notes that are not collected in the original Xilinx datasheet.

XC3090L-6TQ176C - 3.3V 9000-Gate FPGA, 176-Pin TQFP | Xilinx
XC3090L-6TQ176C

XC3090L-6TQ176C - 3.3V 9000-Gate FPGA, 176-Pin TQFP | Xilinx

The Xilinx XC3090L-6TQ176C is a low-voltage (3.3 V) Logic Cell Array (LCA) FPGA from the legacy XC3000L family, integrating approximately 9,000 usable gates into a 176-pin TQFP (TQ) package. It is built on a 0.8-micron CMOS SRAM process with six speed-grade -6 timing, and is intended for digital logic prototyping and small-volume glue-logic designs where 5 V-only XC3000 parts are not an option. An FPGA (Field Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells, all defined by a bitstream stored in SRAM configuration memory. The XC3000L is the low-voltage (3.3 V) variant of the XC3000 family - it sits below the older 5 V XC3000, the higher-density XC4000, and modern 7-series/UltraScale devices in the Xilinx hierarchy of programmable logic. Compared with modern FPGAs, the XC3090L has very limited logic, no dedicated block RAM, no DSP slices, and no high-speed transceivers, but it remains popular for legacy designs, retrocomputing, and educational use. Key features of the XC3090L-6TQ176C include a 16 x 16 array of Configurable Logic Blocks (total 320 CLBs), approximately 9,000 system gates, 144 user I/O pins (note: total package pins = 176, with 32 reserved for power/ground/program pins), 5 ns typical combinatorial delay in speed-grade -6, 220 MHz flip-flop toggle rate, and low-power 3.3 V CMOS I/O. The TQ176 (TQFP-176) package provides a 1.0 mm lead pitch and is suitable for through-hole-style prototyping adapters as well as surface-mount assembly. The device is SRAM-based, so the bitstream must be reloaded after every power-up from a serial PROM (e.g., XC1736A) or microcontroller. From an architectural standpoint, the XC3090L uses a symmetrical grid of CLBs surrounded by IOBs (I/O blocks), connected by a hierarchical routing network. Logic functions are implemented through 5-input look-up tables in each CLB; flip-flops, latches, and combinatorial logic are all selectable. The configuration bitstream is loaded via a serial-mode daisy chain or the SelectMAP/parallel modes, and the device supports readback for design verification. Typical applications include legacy 3.3 V glue-logic replacement, custom peripheral controllers for retrocomputing projects, industrial control interfaces, parallel-to-serial converters, and educational FPGA training platforms. The wide 3.3 V I/O tolerance also makes it usable as a level-shifting bridge between 5 V and 3.3 V domains when paired with appropriate bus hold or pull-up resistors. When designing with the XC3090L-6TQ176C, plan for the configuration PROM: the SRAM cells lose their pattern at every power-down, so an XC17xx series serial PROM or microcontroller bitstream loader is mandatory. Decoupling must follow the datasheet guidelines (typically one 0.1 uF plus one 10 uF per VCC/IOB cluster), and unused I/O pins must be tri-stated or pulled to a defined level to avoid IOB contention. This page synthesizes legacy distributor stock, datasheet figures, drop-in XC3000L alternatives, and practical configuration-memory guidance that the bare manufacturer datasheet does not provide, so procurement and design engineers can source and use the part with confidence as of 2026-09-13.
