XC2C256-7TQ144C

XC2C256-7TQ144C - 256-Macrocell CoolRunner-II CPLD | AMD Xilinx

The AMD Xilinx XC2C256-7TQ144C is a CoolRunner-II Complex Programmable Logic Device (CPLD) with 256 macrocells, approximately 6K gates, and a maximum toggle frequency of 152 MHz, housed in a 144-pin TQFP (Thin Quad Flat Pack, 20x20 mm) surface-mount package. A CPLD (Complex Programmable Logic Device) is a class of programmable logic integrated circuit, sitting between SPLDs such as GAL/PAL devices and FPGAs in the programmable logic hierarchy. CPLDs provide non-volatile configuration, deterministic pin-to-pin timing, and abundant macrocells interconnected through a programmable interconnect matrix, making them ideal for glue logic, state machines, and power-up control where a full FPGA would be oversized. The XC2C256-7TQ144C belongs to the CoolRunner-II family, fabricated on a 0.18 um CMOS process. Its defining characteristic is extremely low static power: unlike PAL-style CPLDs that use sense-amp interconnect, CoolRunner-II uses a fast, low-power interconnect architecture delivering deterministic 7 ns speed grade performance with very low quiescent current. The device supports I/O standards including LVTTL, LVCMOS (3.3V, 2.5V, 1.8V, 1.5V), SSTL, and HSTL on its 118 user I/O, with Schmitt-trigger inputs, hot-plugging capability, and optional input hysteresis for noise immunity. Technical depth: each macrocell contains a combinable/sum-of-products function block, and the Advanced Interconnect Matrix routes signals globally with predictable delays. Design entry and programming are performed in AMD/Xilinx ISE design tools; the non-volatile configuration survives power cycling and supports in-system programming (ISP) via the JTAG interface, enabling field updates of the logic design. Typical applications include bus interface bridging, address decoding, power-sequencing control, industrial control state machines, legacy processor support logic, and mobile/battery-powered systems where the CoolRunner-II low static power advantage directly extends battery life. Design consideration: because CoolRunner-II is a 1.8V-core device, observe the recommended power-up sequencing and use the dedicated VCCINT/VCCIO rails correctly; also apply Schmitt-trigger configuration on inputs driven from slow or noisy edges. This page adds value beyond the manufacturer datasheet by synthesizing distributor stock channels, drop-in same-family alternative part numbers, application guidance, and a parameter comparison table in one place.

XC2C256-7TQ144I

XC2C256-7TQ144I - CoolRunner-II CPLD 256MC TQFP-144 | AMD Xilinx

The AMD (Xilinx) XC2C256-7TQ144I is a CoolRunner-II Complex Programmable Logic Device (CPLD) with 256 macrocells, 118 inputs and 118 outputs, a maximum clock frequency of 108 MHz, and a worst-case propagation delay of 6.7 ns, housed in a 144-pin TQFP (TQ144) package with an industrial temperature rating of -40C to +125C. A CPLD is a type of programmable logic device that sits between discrete SPLD devices (such as PAL/GAL/PALCE) and large FPGAs in the programmable-logic hierarchy. CPLDs provide deterministic, pin-to-pin timing, instant-on operation, and non-volatile configuration storage, which makes them the preferred glue-logic, bus-interface, and power-sequencing fabric in systems where an FPGA would be oversized or too slow to boot. The defining feature of the CoolRunner-II family is its ultra-low power architecture: unlike macrocell CPLDs built on high-power analog fast-switching technology, CoolRunner-II is fabricated on a 1.8 V core CMOS process that consumes orders of magnitude less static current. The -7 speed grade in this suffix denotes the 6.7 ns timing bin, and the trailing 'I' designates the industrial temperature range. The device integrates 256 macrocells organized into function blocks of 16 macrocells each, with a programmable interconnect matrix that ties all 118 I/Os to the internal fabric. Each macrocell supports combinational and registered modes, global three-state controls, and multiple clocking options. Design entry and compilation are performed with the AMD/Xilinx ISE toolchain. Typical applications include address decoding and bus interfacing in microprocessor systems, FPGA configuration management and power-sequencing control, protocol bridging and glue logic in industrial automation, handheld and portable equipment where CPLD power budget is critical, and legacy ASIC/ASSP replacement in medical and communication boards. When designing with this device, remember that the 1.8 V core is internally regulated while I/O banks operate at 1.5 V to 3.3 V; verify that VCCIO banking matches the interfacing voltage standard (LVCMOS levels) before finalizing PCB stack-up.

XC2C256-7TQG144C

XC2C256-7TQG144C - 256-Macrocell 6.7 ns CPLD | AMD

The AMD XC2C256-7TQG144C is a CoolRunner-II complex programmable logic device with 256 macrocells, a 6.7 ns propagation delay, and 118 I/O pins in a 144-pin TQFP package. It provides approximately 6000 gates of logic for compact programmable control, interface, and signal-routing designs. A complex programmable logic device, or CPLD, is a programmable-logic semiconductor that combines interconnected macrocells with programmable interconnect. In the broader hierarchy, a CPLD is a programmable logic device and an FPGA alternative. Unlike mask-programmed logic, a CPLD permits design changes without fabricating a new integrated circuit. The CoolRunner-II architecture also uses nonvolatile configuration storage, allowing the programmed logic to remain available after power is removed. The XC2C256 family provides 16 logic array blocks and 256 macrocells according to the available product data. Its -7 speed designation corresponds to the reported 6.7 ns propagation-delay class. With 118 user I/O pins, it supports parallel external interfaces and board-level control functions. The 1.7 V to 1.9 V internal supply range is suitable for systems designed around the device's documented core operating conditions. Typical uses include industrial control, communications equipment, portable electronics, programmable interface logic, bus arbitration, and compact control-plane functions. The CPLD can consolidate multiple fixed-function gates into one programmable device, reducing board area compared with a larger gate-array implementation when the required logic is modest. Designers should still verify timing, power, I/O standards, and pin constraints against the complete CoolRunner-II datasheet and their specific design. The principal design consideration is tool and configuration compatibility. Existing CoolRunner-II projects depend on supported AMD or Xilinx programming tools, device support, and verified bitstream compatibility. Before replacing an installed device, engineers must check the exact package, speed grade, temperature grade, power behavior, and pin assignment rather than relying only on the family name. This page consolidates the supplied distributor and manufacturer information, distinguishes verified facts from unavailable specifications, and adds selection and sourcing guidance. Because the provided data does not include a complete pin table, electrical limit table, or qualified replacement list, those fields remain explicitly marked for engineering review.

XC2C256-7VQ100C - CoolRunner-II CPLD 256MC 1.8V | Xilinx
XC2C256-7VQ100C

XC2C256-7VQ100C - CoolRunner-II CPLD 256MC 1.8V | Xilinx

The Xilinx (AMD) XC2C256-7VQ100C is a CoolRunner-II Complex Programmable Logic Device (CPLD) with 256 macrocells, 6K system gates, a 7 ns pin-to-pin propagation delay, and 118 user I/O pins, housed in a 100-pin VQ100 thin-quad flat package (TQFP/VQFP) for commercial temperature operation. Fabricated in a 0.18 um CMOS process, it operates from a single 1.8 V core supply and supports internal clock frequencies up to 152 MHz. A CPLD (complex programmable logic device) is a class of programmable logic IC that sits between simple PAL/GAL devices and large FPGAs in the programmable-logic hierarchy. CPLDs use a deterministic, macrocell-based architecture that delivers fixed, predictable timing from input to output, making them the standard choice for glue logic, state machines, bus interfacing, power-sequencing control, and address decoding where every switching event has a known worst-case delay. The defining feature of the CoolRunner-II family is its extremely low power profile. Because the XC2C256 uses a 1.8 V core rather than the 3.3 V or 5 V rails of older CPLD generations, dynamic and static power consumption are dramatically reduced, which is why the family is widely used in battery-powered and thermally constrained systems. The device also supports ISE design tools and offers schmitt-trigger inputs, optional dual-DLL clocking resources, and flexible macrocell architecture for high logic utilization. With 256 macrocells and 118 user I/Os in a 0.5 mm-pitch 100-pin QFP, the XC2C256-7VQ100C provides one of the highest densities of the CoolRunner-II family in a surface-mount package that is easy to inspect and rework. The -7 speed grade denotes the 7 ns commercial-grade worst-case pin-to-pin delay; industrial (I-suffix) and Pb-free/green (VQG100) variants share the same die and footprint. Typical applications include embedded-system glue logic and bus bridging, microcontroller/FPGA boot and configuration control, industrial control panels, portable and battery-operated instruments, and communications line-card control functions. Anywhere a deterministic, non-volatile-configured logic device with near-zero standby power is required, this CPLD fits. Designers should confirm I/O bank voltage compatibility and use the Xilinx ISE toolchain for fitting; the same footprint accepts industrial and green variants, simplifying second-source within the family. This page adds engineering value beyond the datasheet: drop-in family alternatives, a parameter comparison table, practical design notes, application guidance, and sourcing information synthesized for procurement and design engineers.

XC2C256-7VQ100I

XC2C256-7VQ100I - CoolRunner-II CPLD 256 Macrocells | AMD Xilinx

The AMD Xilinx XC2C256-7VQ100I is a CoolRunner-II Complex Programmable Logic Device (CPLD) with 256 macrocells, a worst-case propagation delay of 6.7 ns, and system performance up to 152 MHz, housed in a 100-pin VQFP (VQ100, 14x14 mm) package and rated for the industrial temperature range. A CPLD (Complex Programmable Logic Device) is a class of programmable logic IC that sits between simple SPLDs such as GAL/PAL devices and full FPGAs in the programmable logic hierarchy. CPLDs implement user-defined combinational and sequential logic in a non-volatile, deterministic fabric: unlike SRAM FPGAs, a CoolRunner-II CPLD applies its configuration immediately at power-up with no configuration time or external configuration memory, which makes it a common glue-logic, bus-interface and power-up-control component in embedded systems. Key features of the XC2C256 include a 1.8 V core supply for very low static power, a real-time reprogrammable function block architecture with 256 macrocells, dual output banks that can switch to two independently selected output voltage levels, and Schmitt-trigger capable inputs for noisy board environments. The -7 speed grade delivers a 6.7 ns pin-to-pin delay, enabling deterministic timing in control-path logic. Architecturally, the CoolRunner-II family combines programmable function blocks with a low-power switching matrix. Each macrocell can be configured as combinational or registered logic, and the global routing matrix provides predictable, pin-to-pin timing across the device. Because the fabric is 1.8 V powered with I/O banks that support multiple standards, the device integrates cleanly into mixed-voltage boards. Typical applications include address decoding and bus interfacing in industrial controllers, power-up sequencing and reset control, handheld and battery-operated equipment where standby power matters, and bridging between processors and peripherals in communication hardware. Design consideration: budget the 1.8 V core rail separately from the I/O bank rails, and use the manufacturer datasheet pin-description table when assigning PCB tracks on the VQ100 footprint. This page synthesizes distributor availability, drop-in same-family alternatives, comparison tables, and practical design notes not found in the manufacturer datasheet alone.

XC2C32A-4CP56C - 32-Macrocell 450 MHz CPLD | AMD Xilinx
XC2C32A-4CP56C

XC2C32A-4CP56C - 32-Macrocell 450 MHz CPLD | AMD Xilinx

The AMD Xilinx XC2C32A-4CP56C is a 32-macrocell CoolRunner-II complex programmable logic device with a 450 MHz internal frequency, up to 33 user I/Os, and a 3.8 ns propagation delay. It is optimized for 1.8 V systems and supplied in a compact 56-pin CSPBGA package measuring 6 x 6 mm with a 0.50 mm ball pitch. These specifications make the CPLD suitable for space-constrained embedded systems requiring deterministic programmable logic, compact PCB routing, and low-power operation. A CPLD is a programmable logic device that combines multiple macrocells and programmable interconnect resources into a deterministic logic fabric. Its hierarchy is CPLD > complex programmable logic device > programmable logic device > programmable logic semiconductor. Unlike a soft-core processor or FPGA, a CPLD is generally configured from a stored bitstream and is selected when relatively modest logic density, predictable timing, low static power, and simple implementation are more important than very high programmable-resource counts. The XC2C32A-4CP56C provides 32 macrocells, 33 user I/Os, a 450 MHz internal frequency, and a 3.8 ns rated propagation delay. The device uses 0.18 µm CMOS technology, supports 1.8 V operation, and can reach 3.0 ns pin-to-pin logic delays. A reported quiescent current as low as 12 µA is particularly useful in portable or power-managed equipment where the logic remains active or intermittently enabled. The 56-pin CSPBGA package reduces board area relative to larger leaded or plastic packages, but its 0.50 mm pitch requires careful PCB layout, fine-pitch assembly, and appropriate land-pattern validation. Ball-level solder inspection and adequate thermal-via placement should be considered during hardware qualification. The commercial temperature designation indicated in the verified listings should also be checked against the complete ordering information and end-product environmental requirements. Typical uses include interface control, protocol bridging, data acquisition, industrial control, embedded glue logic, and general-purpose compact control systems. In each case, designers should verify I/O standard, timing, power rails, and pin assignment against the AMD DS310 datasheet before releasing a PCB or production design. The primary engineering trade-off is that the 56-ball footprint saves area but complicates assembly compared with a leaded package. Design for the specified 1.8 V supply, preserve the recommended decoupling and layout geometry, validate worst-case timing, and confirm programming-tool and device support before committing to production. This page consolidates verified device specifications, source links, package constraints, and practical CPLD-selection guidance. It also distinguishes directly evidenced drop-in information from substitutions that still require manufacturer pinout and timing verification.

It uses 0.18 µm CMOS technology and is optimized for 1.8 V systems. The -4 speed grade supports operation to 200 MHz, while the listed propagation-delay range reaches 4 ns for applicable logic paths. A CPLD is a programmable digital-logic device that combines a logic architecture, nonvolatile configuration memory, and user-programmable I/O in one package. The CoolRunner-II family sits between simple programmable logic and larger FPGAs: it provides deterministic timing, in-system programmability, and a compact macrocell structure for consolidating Boolean equations, counters, decoders, state machines, and control logic. Within the semiconductor hierarchy, a CPLD is a programmable-logic IC and a user-programmable digital semiconductor. The XC2C32A offers 750 logic gates, 32 macrocells, and up to 33 user I/O pins. Its 0.18 µm CMOS implementation supports fast pin-to-pin logic delays, including a listed minimum of 3.8 ns, while the -4 device is rated at 200 MHz. Quiescent current is listed as low as 12 µA, making the device suitable for portable, low-power control systems as well as fixed industrial logic. The CSP-56 package has a 6 × 6 mm body and 0.50 mm ball pitch. The device is intended for in-system programmable logic and supports two I/O banks in the XC2C32A version. This bank structure allows interfaces to be grouped according to voltage requirements, provided each selected interface stays within the device's specified electrical limits. Its macrocell-based architecture is optimized for effective logic synthesis, making it practical to implement glue logic, bus decoding, protocol conversion, and system-control functions without a large FPGA. Typical applications include industrial control interfaces, communication protocol bridges, data-acquisition front ends, embedded system glue logic, and low-power portable electronics. It can also implement bus arbitration, address decoding, pulse-width modulation generation, status sequencing, and peripheral interfacing where deterministic behavior and a compact package are more important than very high logic capacity. Designers should use the AMD DS310 pin description and package drawing to assign every ball, including power, ground, configuration, and unused I/O connections. Decoupling and signal-routing guidance should follow the CoolRunner-II recommended PCB practices, while timing constraints must reflect the actual -4 speed grade, selected I/O standard, and external clock or interface conditions. This page organizes the key XC2C32A-4CPG56C specifications, package constraints, pin-compatible family alternatives, and application guidance into a compact engineering reference. It supports design partitioning, sourcing, and replacement planning while highlighting where device speed, package, and qualification requirements must be checked before a board is released.

XC2C32A-4PC44C 32-Macrocell 4 ns CPLD | AMD/Xilinx

The AMD/Xilinx XC2C32A-4PC44C is a CoolRunner-II complex programmable logic device with 32 macrocells, 750 logic gates, and a maximum operating frequency of 323 MHz. The -4 speed grade provides a 4 ns performance designation, while the commercial-temperature device is supplied in a 44-terminal PQCC surface-mount package measuring 16.5 mm by 16.5 mm with a 1.27 mm lead pitch. A complex programmable logic device, commonly called a CPLD, belongs to the programmable-logic hierarchy alongside FPGAs. Unlike a fixed combinational logic circuit, a CPLD stores its configuration in nonvolatile flash memory. After programming, the device implements digital logic directly in hardware, providing deterministic operation without executing software on a microcontroller or processor. The CoolRunner-II architecture combines 32 macrocells with 750 available gates in a low-power 0.18 µm process. Its in-system programmability permits a board to be configured or updated without removing the device from the assembled PCB. The commercial grade and surface-mount package are suited to industrial control, communications, consumer, and embedded equipment where compact configurable logic is required. Typical uses include bus-interface translation, control-signal generation, protocol bridging, state-machine implementation, display-control logic, and general glue logic around microcontrollers. The 32-macrocell capacity allows moderate combinational and sequential functions to be consolidated without introducing the resource overhead of a larger programmable-logic device. PCB design should preserve the manufacturer's recommended power, ground, configuration, and programming connections. Confirm the exact pin names and configuration requirements in the AMD/Xilinx CoolRunner-II documentation before routing the PCB, because the component combines user I/O with dedicated power and configuration functions. This page compares package and family variants, identifies genuine same-footprint replacements, and summarizes selection and implementation considerations that help engineers evaluate the XC2C32A-4PC44C beyond a basic distributor specification table.

XC2C32A-4QFG32C - 32-Macrocell 1.8V CPLD | AMD | Logic Control

The AMD XC2C32A-4QFG32C is a CoolRunner-II complex programmable logic device with 32 macrocells, a 1.8 V core supply, a speed grade of -4, and a 32-pin QFN surface-mount package. Its 0.18 µm CMOS architecture supports logic densities up to 750 gates, while the device provides in-system programmability for compact control, interface, and glue-logic designs. A CPLD is a user-programmable digital logic device classified as a programmable logic semiconductor. In the product hierarchy, a CPLD sits below FPGA and above fixed-function logic. Unlike a mask-programmed device, it can be configured after manufacture, making it useful for prototypes, production controllers, bus adapters, signal conditioning, and legacy system integration. The CoolRunner-II architecture combines nonvolatile configuration storage with predictable interconnect timing. The XC2C32A family is optimized for 1.8 V systems and supports logic delays as fast as 3.0 ns, depending on the characterized path and loading conditions. The -4 designation identifies the device speed grade, while published comparison information lists an internal frequency of 323 MHz. Its architecture includes configurable output-pin functions such as slew-rate control, bus hold, pull-up, open-drain operation, and programmable grounds. Individual input pins may also use a Schmitt-trigger function for improved handling of slower or noisy signals. The 32-macrocell device provides a practical balance between logic density, pin count, and routing predictability. A comparison record identifies 750 gates, 32 macrocells, and 0.18 µm CMOS technology for the XC2C32A family. Its macrocell architecture supports registered outputs as well as direct-input register configurations, allowing output-state storage, pipelining, and state-machine implementation. Configuration retention and boundary behavior are managed through the CoolRunner-II feature set. Typical applications include compact peripheral controllers, bus interface logic, protocol converters, industrial control modules, instrumentation signal conditioning, and embedded system support logic. The in-system programming capability allows a board designer to configure the same physical CPLD for different hardware personalities, while the relatively small QFN-32 package supports compact boards where a larger FPGA would be unnecessary. The primary design constraint is the limited logic and I/O capacity of 32 macrocells. Engineers should reserve resources for configuration pins, dedicated inputs, power, ground, and board-level programming access. Signal-integrity planning should also account for the 1.8 V core environment and package routing density. Validate the final pin assignment, timing, and JTAG implementation against the AMD CoolRunner-II XC2C32A datasheet. This product overview combines the verified family specifications, package information, search-demand queries, and practical engineering guidance needed to evaluate the XC2C32A-4QFG32C. The comparison table also distinguishes documented speed-grade and package options, helping engineers identify a suitable drop-in device without confusing a pin-compatible change with an unqualified redesign.

XC2C32A-4VQG44C

XC2C32A-4VQG44C - 32-Macrocell 1.8V CPLD | AMD Xilinx

The AMD Xilinx XC2C32A-4VQG44C is a CoolRunner-II complex programmable logic device (CPLD) built around 32 macrocells and 33 user I/O pins. It is specified for 1.8V systems, uses CMOS programmable logic technology, and is packaged in a 44-pin VQFP-style package. The -4 speed grade is identified in the family documentation with approximately 3.8 ns propagation delay, while one product listing identifies an internal frequency of 450 MHz and an operating temperature range extending to 125 °C. The device is intended for deterministic glue logic, bus interfacing, control logic, signal conditioning, and low-power embedded systems. A CPLD is a programmable logic device that combines multiple macrocell logic sections into one reconfigurable integrated circuit. Unlike a mask-programmed fixed-function logic device, a CPLD can be programmed after manufacture, allowing designers to implement control, decoding, multiplexing, and interface functions in a compact device. The CoolRunner-II family combines a CMOS CPLD architecture with low-power operation and in-system programmability, making it useful for designs that require flexible logic without the resource complexity of a large FPGA. The XC2C32A provides 32 macrocells, approximately 750 logic gates according to the family comparison information, and 33 user I/Os. Its listed features include in-system programmability, hot-pluggable PLA architecture, and high pinout retention. The device is optimized for 1.8V systems and is described as offering pin-to-pin replacement compatibility with earlier XC2C32 devices when used with the appropriate AMD Xilinx cross-reference information. These characteristics make it useful for legacy and modernization designs where maintaining the existing board footprint is important. The -4 suffix identifies the performance grade of this device, while VQG44C identifies the package and temperature-related ordering configuration. The package information reported for the target varies between distributor and catalog pages, with 44-pin VQFP notation used for the target and a separate catalog entry describing a 56-pin CSP configuration. Engineers should therefore confirm the mechanical drawing and pin assignment against the exact package suffix before releasing a PCB footprint. The CPLD is not a power semiconductor, so a safe-operating-area chart is not applicable. Typical applications include bus arbitration, address decoding, control-signal generation, peripheral interfacing, industrial control boards, and compact embedded control systems. The 33 user I/Os can be assigned to digital inputs and outputs, while the programmable macrocells implement Boolean equations, counters, state machines, and registered logic. The 1.8V operating focus helps reduce power consumption in systems where the CPLD interfaces with modern low-voltage processors, transceivers, and memory components. Design planning should begin with the pin assignment table and the CoolRunner-II device documentation. Confirm that the selected package has the required power, ground, configuration, clock, and user I/O assignments, and use the exact package suffix to select the correct PCB land pattern. Designers should also account for the programmable logic and I/O limitations of the 32-macrocell device rather than assuming FPGA-scale resources. This page consolidates the part identity, package caveats, documented family characteristics, replacement guidance, and practical design considerations into an engineering-focused component reference.

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.

It combines programmable logic, in-system programmability, and low-power operation in a compact surface-mount package for embedded control and interface designs. A complex programmable logic device, or CPLD, is a user-programmable semiconductor within the FPGA and programmable-logic hierarchy. Unlike a fixed-function logic circuit, a CPLD combines nonvolatile configuration, macrocell-based logic, and programmable I/O in one device. The CoolRunner-II architecture targets designs that need deterministic logic density, compact implementation, and straightforward peripheral integration without the resource structure of a larger FPGA. Key features include 32 macrocells, 33 I/O, operation optimized for 1.8 V systems, and a 3.8 ns pin-to-pin delay. The device is manufactured using 0.18 µm CMOS technology and is identified as a 750-gate CoolRunner-II device. Its VQFP-44 surface-mount package supports compact PCB layouts while exposing the logic, power, ground, configuration, and I/O resources needed for compact control systems. The XC2C32A architecture supports in-system programming, allowing configuration behavior to be integrated into a larger embedded system. 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.

XC2C384-7PQ208C - 384-Macrocell CPLD, 7.1ns | Xilinx

The AMD/Xilinx XC2C384-7PQ208C is a CoolRunner-II CPLD (Complex Programmable Logic Device) offering 384 macrocells, 240 user I/O pins, and a fast 7.1 ns pin-to-pin propagation delay, housed in a 208-pin PQFP (PQ208) surface-mount package optimized for 1.8V systems. A CPLD is a type of programmable logic device that combines a large number of macrocells with a programmable interconnect fabric, sitting in the system hierarchy between simple SPLDs (such as GAL and PAL devices) and full FPGAs. Unlike SRAM-based FPGAs, CoolRunner-II CPLDs configure instantly at power-up from on-chip flash, making them voltage regulators of glue logic: they replace many discrete 74-series logic ICs, perform address decoding, bus interfacing, and state-machine control with zero external configuration storage. Key features of the XC2C384-7PQ208C include its industry-leading 0.18 micron CMOS CPLD process, 7.1 ns pin-to-pin delay performance in the -7 speed grade, and quiescent current as low as 14 microamps, which makes it one of the lowest-power members of the programmable logic family. The 240 available user I/O provide high pin-count glue-logic integration, and the commercial temperature grade covers 0 C to +70 C. Architecturally, the CoolRunner-II family uses a fast, deterministic interconnect that avoids the variable routing delays of FPGA fabrics, so timing closure is straightforward: the 7.1 ns pin-to-pin figure holds across typical designs. The 1.8V core optimization reduces dynamic power dramatically compared with earlier 3.3V CPLD generations, while I/O banks tolerate standard logic levels for mixed-voltage board integration. Typical applications include address decoding and bus bridging in embedded systems, power-up configuration control for larger FPGAs, interface conversion between legacy and modern logic families, and portable or battery-powered designs where the 14 microamp standby current directly extends battery life. Design consideration: assign unused I/O as grounded outputs or inputs with termination per the manufacturer datasheet guidelines, and verify I/O bank voltage compliance before mixing 3.3V and 1.8V signals on the same bank.

The AMD (Xilinx) XC2C384-7TQ144C is a CoolRunner-II family CPLD (complex programmable logic device) with 9K system gates, 384 macro cells, a 7.1 ns pin-to-pin propagation delay and 14 uA quiescent current, housed in a 144-pin TQFP (TQ144) surface-mount package rated 0C to +70C. A CPLD is a class of programmable logic device that sits between SPLDs (such as GAL/PAL devices) and FPGAs in the programmable-logic hierarchy. CPLDs use a macro-cell-based architecture with a deterministic, fully-connected programmable interconnect, which means every signal path has a fixed, predictable delay. This makes CPLDs the preferred choice for glue logic, state machines, bus interfacing, power-up sequencing and address decoding, where pin-to-pin timing consistency matters more than raw gate count. Key features of the XC2C384-7TQ144C include its 1.8V supply optimization, which dramatically lowers dynamic power compared to 3.3V and 5V CPLD families, its 0.18-micron CMOS process that yields the industry-fastest 7.1 ns pin-to-pin delays for a low-power CPLD, and an ultra-low 14 uA quiescent current that suits battery-powered and always-on designs. The device offers up to 240 user I/O pins, giving designers extensive pin availability in a 0.5 mm-pitch 144-lead TQFP footprint. Architecturally, CoolRunner-II macro cells combine a programmable AND/OR logic array with configurable registers, supporting combinational and sequential functions per cell. The family is programmed via industry-standard JTAG and is supported by the AMD/Xilinx ISE design suite for synthesis, fitting and in-system programming. Typical applications include bus-interface translation and control, microprocessor glue logic, industrial control sequencing, communications line-card management and replacing multiple discrete logic devices to reduce board area and BOM count. For design, note that 1.8V I/O standards apply - confirm level compatibility with 3.3V host devices before committing the board, and follow the manufacturer datasheet for JTAG programming-chain requirements.

XC2C64A-5CP56C - 64-Macrocell 1.8V CPLD | AMD

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.

It operates from a 1.8 V core supply and is designed for low-power, nonvolatile programmable logic in compact embedded systems. The -5 speed designation corresponds to a listed 263 MHz internal frequency, while individual path delays are characterized separately. A CPLD is a programmable logic device that combines programmable AND/OR logic structures with a nonvolatile configuration memory architecture. In the electronics hierarchy, a CPLD is a user-programmable digital semiconductor used for control logic, interface translation, decoding, state machines, and bus arbitration. Unlike a mask-programmed logic device, it can be configured after manufacture, while its nonvolatile configuration allows operation without continuously loading a program into volatile memory. The XC2C64A provides 64 logic macrocells and as many as 45 user I/O pins, making it suitable for designs that need substantially more routing flexibility than discrete gates. 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.

The XC2C64A family provides up to 4.6 ns pin-to-pin logic delays and supports 1.8 V systems. Its low 15 A quiescent current is suitable for power-conscious embedded equipment. In-system programming allows configuration or field updates without removing the device from its circuit, while the 64-macrocell architecture accommodates control logic, interface adaptation, state machines, and fixed-footprint hardware customization. The 0.18 µm CMOS implementation combines nonvolatile configuration storage with deterministic CPLD timing. The -5 suffix identifies a particular speed grade, while QFG48C identifies the 48-lead QFN exposed-pad package and commercial temperature designation. The exposed pad supports heat transfer from the device to the PCB, making copper placement and thermal analysis important in compact embedded systems. Typical applications include industrial control, embedded instrumentation, communications-interface adaptation, low-voltage consumer electronics, and compact control systems. A 37-I/O device can connect processors, sensors, memory interfaces, status indicators, and discrete I/O when the design does not require the capacity or routing flexibility of a larger FPGA. The primary design consideration is maintaining a clean 1.8 V rail and providing adequate thermal copper beneath the exposed pad.

A CPLD (Complex Programmable Logic Device) is a class of programmable logic IC that sits between simple SPLD devices such as GAL/16V8 parts and full FPGAs in the programmable logic hierarchy. CPLDs provide deterministic, pin-to-pin timing for glue logic, state machines, bus interfacing, and power-on configuration control, and are non-volatile - the design is retained through power cycles without external configuration memory. Key features of the XC2C64A include the industry-leading 0.18 micron CMOS process optimized for 1.8 V systems, as low as 15 uA quiescent current, internal frequencies up to 333 MHz, and in-system programmability (ISP). The CoolRunner-II architecture delivers extremely low dynamic power because it uses a true 1.8 V core rather than 3.3 V or 5 V legacy cores, making it well suited to battery-powered and thermally constrained designs. Technically, the XC2C64A provides 4 function blocks containing 16 macrocells each, supporting both combinational and registered logic with synchronous and asynchronous resets. The -5 speed grade offers 4.6 ns pin-to-pin delay and 263 MHz system toggle performance, with DataGate and CoolPower technologies further reducing active power. Schmitt-trigger inputs, optional dual-DATA-gate inputs, and 3.3 V-tolerant I/O standards through level-shifting ease mixed-voltage system integration. Typical applications include glue logic consolidation in embedded systems, power-up sequencing and FPGA configuration control, address decoding, bus bridging, portable and battery-operated instrumentation, and industrial control boards where deterministic timing and non-volatile logic are required. Design consideration: the 1.8 V core supply requires a clean, well-decoupled rail; I/O banks may interface to 3.3 V systems, but check the DS311 datasheet I/O standard selection in your tools before committing pin assignments.

XC2C64A-5VQ44C - 4.6ns 64-Macrocell CPLD | AMD

AMD Xilinx XC2C64A-5VQ44C is a 64-macrocell CoolRunner-II complex programmable logic device with a 4.6 ns pin-to-pin logic delay, a 333 MHz internal frequency, and a 44-pin VQFP package. It is a CMOS programmable logic device intended for deterministic signal processing, communications, industrial automation, and custom hardware acceleration. The -5 speed designation identifies the 4.6 ns performance grade, while the 44-pin package supports compact, surface-mount PCB implementations. A CPLD is a programmable logic device that combines programmable AND/OR logic structures with non-volatile configuration memory. The XC2C64A belongs to the CoolRunner-II CPLD hierarchy, which sits between fixed-function logic and larger field-programmable gate arrays. It is useful when a design needs deterministic propagation timing, in-system reconfiguration, and a modest logic-cell count without the complexity of an FPGA or processor-based implementation. The device provides 64 macrocells and approximately 1.5K gates according to the verified product data. Its 4.6 ns pin-to-pin delay supports moderate-speed control, decode, glue-logic, and interface tasks. The listed 333 MHz internal frequency provides additional timing context, while its optimized 1.8 V architecture targets modern low-voltage digital systems. A 15 A quiescent-current figure appears in the supplied specification extract, although the intended operating supply details should be confirmed in the manufacturer datasheet before power budgeting. Typical uses include communications equipment, industrial automation, real-time signal processing, bus-interface control, data-capture front ends, and embedded control logic. The CPLD is particularly suitable for deterministic designs requiring several interconnected state machines, protocol converters, or glue-logic functions around microcontrollers and processors. Its macrocell architecture also allows designers to consolidate small controller sections into one programmable device rather than using several unrelated fixed-function ICs. Designers should verify power-supply voltage, I/O standards, available package variants, and acquisition-file compatibility in the DS311 device documentation. PCB layouts should preserve adequate ground and power distribution, and unused inputs must be handled according to the manufacturer guidelines. This page synthesizes the supplied specifications, sourcing information, speed-grade alternatives, and design guidance into a compact engineering reference for the XC2C64A-5VQ44C.
