XC2C64A-7VQ44C - 64-Macrocell 6.7ns CPLD | AMD
Référence : XC2C64A-7VQ44C ✓ ActifXC2C64A-7VQ44C Présentation
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.

Applications typiques
XC2C64A-7VQ44C convient pour 6 applications: Embedded Processor Peripheral Logic, Industrial Control and Interlock Logic, Communication Interface Adaptation, Data Acquisition and Signal Conditioning, LED Lighting and Display Sequencing, Audio Interface Control.
Embedded Processor Peripheral Logic
The XC2C64A-7VQ44C fits glue-logic and peripheral-adaptation tasks around embedded processors because it provides 64 macrocells, 45 user I/Os, and a 6.7 ns maximum propagation-delay class. It can implement address decoding, interrupt qualification, bus arbitration, and status-register logic without occupying a large FPGA. The 1.7 V to 1.9 V internal supply is aligned with low-voltage embedded systems, although each external interface must satisfy the supported I/O standards. Its practical benefit is deterministic, compact logic integration with a short critical path, but timing must be closed against the actual processor interface rather than inferred from the standalone frequency figure.
Recommandé
Industrial Control and Interlock Logic
The XC2C64A-7VQ44C is suitable for industrial control blocks that require deterministic combinational decisions, machine interlocks, and compact I/O coordination. Its 64 macrocells are sufficient for several control paths, while the 45 user I/Os can support digital inputs, outputs, and status signaling. The 6.7 ns maximum propagation-delay class helps when control outputs must react quickly to changing machine state. For safety-related or harsh-environment equipment, engineers must still check operating temperature, electrical limits, isolation, and applicable qualification because those values were not available in the verified source snippets.
Recommandé
Communication Interface Adaptation
The XC2C64A-7VQ44C can bridge incompatible digital interfaces, perform protocol framing, and implement level-independent control logic around communications peripherals. Its 45 user I/Os provide practical connectivity for serial signals, chip selects, interrupts, and status flags, while the 6.7 ns propagation-delay class supports relatively fast deterministic paths. The device is especially useful where the surrounding processor lacks the required pins or where several small interface rules must be consolidated. Signal-integrity checks remain essential for high-speed data lines because CPLD timing specifications do not replace controlled-impedance routing or external transceiver analysis.
Recommandé
Data Acquisition and Signal Conditioning
The XC2C64A-7VQ44C is useful for fixed data-acquisition logic that must synchronize sensor lines, latch control states, and format data before it reaches a processor. The 45 user I/Os allow multiple sensor or control channels to be consolidated, and 64 macrocells provide space for state-machine and datapath functions. Its fast 6.7 ns maximum delay class can help minimize combinational latency in sampling and trigger paths. Analog accuracy remains determined by the sensors and converters, so the CPLD should be used for digital control rather than represented as an analog precision device.
Recommandé
LED Lighting and Display Sequencing
The XC2C64A-7VQ44C can implement deterministic display sequencing, LED blanking, keypad scanning, and indicator-control logic in a compact embedded system. Its 45 user I/Os allow multiple display and indicator signals to be managed, and the 6.7 ns propagation-delay class supports fast transition handling without a large FPGA. The CPLD can also coordinate asynchronous commands with a display controller, reducing host-processor overhead. Because the device does not regulate LED current, external drivers and suitable resistors remain necessary, and timing margins should be verified under the chosen panel-loading conditions.
Recommandé
Audio Interface Control
The XC2C64A-7VQ44C fits audio equipment that requires digital mute, routing, format conversion, and status-control logic around a codec. Its 45 user I/Os support control signals and multiple digital interfaces, while the 6.7 ns maximum delay class helps implement deterministic control paths. The CPLD may consolidate mode selection, interrupt handling, and clock-domain control without using a large FPGA. Audio-clock and data-line quality must still be designed carefully, and the component's internal 1.7 V to 1.9 V supply should not be confused with the voltage tolerance of every user I/O.

Notes de conception
Do not approve a footprint from the ordering code alone. The verified sources conflict: the ABC Semi, YIC, Kynix, and Datasheets.com records identify a 44-pin VQFP, while the DigChip snippet classifies the listing as a 56-pin CSP. Download DS311, identify the VQ44 package drawing, and compare every pin position, power connection, configuration pin, and exposed pad before releasing a PCB or substituting another suffix.
Design the 1.8 V internal supply rail with adequate local decoupling and verify sequencing against the DS311 power recommendations. The retrieved 1.7 V to 1.9 V internal range does not imply that every user I/O has the same voltage tolerance or that all outputs can drive 1.8 V loads. Use the official I/O-standard tables, output-current limits, input-threshold data, and power-up behavior rather than inferring electrical compatibility from the internal core voltage.
Treat the 6.7 ns maximum propagation-delay figure as a device timing limit, not as permission to use uncontrolled PCB routing. Constrain fast outputs, keep configuration and clock-like nets away from sensitive inputs, and use a ground plane with short return paths. External level translation or termination may be required for legacy, long-trace, noisy, or non-1.8 V interfaces. Validate these paths with the implemented design and the timing conditions stated in DS311.
Use the exact DS311 land pattern for the 44-pin VQFP and verify the manufacturer's recommended solder-mask and paste details. Place programming-access and configuration-support circuitry where it remains reachable, and provide clean supply connections to every required VCC and ground pin. Because the device is offered in legacy inventory, traceability and date-code handling are as important as the electrical schematic when building or repairing an existing board.
