XC2C64A-7VQ44I - 64-Macrocell 1.8V CPLD | AMD Xilinx
N.º de pieza: XC2C64A-7VQ44I ✗ Fin de vidaXC2C64A-7VQ44I Descripción general
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.

Aplicaciones típicas
XC2C64A-7VQ44I es adecuado para 6 aplicacións: Industrial Control and System Interlocking, Communication Interface Conditioning, Embedded System Glue Logic, Battery-Operated Instrumentation, USB Peripheral Interface Support, Programmable Test and Measurement Control.
Industrial Control and System Interlocking
The XC2C64A-7VQ44I fits compact industrial control logic because its 64 macrocells can implement multiple interlocks, state machines, and discrete control functions while the listed 5 ns propagation delay supports short control-loop decisions. Its 45 user I/O pins also provide substantial board connectivity without requiring a larger programmable device. Place the CPLD between sensor-conditioning circuits and actuators, and preserve the 1.8 V core and I/O-bank requirements defined in AMD DS311. Verify the exact temperature grade before using it in an industrial enclosure.
Recomendado
Communication Interface Conditioning
The XC2C64A-7VQ44I is suitable for communication front ends requiring programmable logic for protocol conversion, command decoding, and bus arbitration. Its listed 4.6 ns pin-to-pin logic delay and 45 user I/O pins allow several low-to-moderate-speed interfaces to coexist in a compact 44-pin package. Use the CPLD to normalize asynchronous control signals or bridge incompatible logic levels, while treating the 1.8 V supply as a key design constraint. Confirm I/O-standard and timing support in DS311 before finalizing the interface.
Recomendado
Embedded System Glue Logic
The XC2C64A-7VQ44I provides 64 macrocells for embedded boot control, watchdog supervision, reset sequencing, peripheral arbitration, and legacy interface adaptation. Its 45 user I/O pins allow the CPLD to connect several sensors, memory-control signals, and status indicators while maintaining a compact surface-mount footprint. The 7 speed grade and reported 4.6 ns pin-to-pin delay help preserve margin in control paths. Designers should use the official pin assignment and verify unused-pin requirements before PCB release.
Recomendado
Battery-Operated Instrumentation
The XC2C64A-7VQ44I can implement low-complexity measurement control, power sequencing, and signal routing in battery-operated instruments where its 64 macrocells provide useful logic density without the resource demand of an FPGA. The listed 159 MHz device designation supports compact high-performance control, while the family is described as suitable for low-power applications. Designers should confirm the exact quiescent-current figure from DS311 because the supplied distributor snippets report an ambiguous current unit and do not permit a defensible battery-life calculation.
Recomendado
USB Peripheral Interface Support
The XC2C64A-7VQ44I is useful beside a USB controller when additional protocol status, FIFO control, interrupt routing, or power sequencing logic is required. Its 45 user I/O pins and 64 macrocells allow dedicated support logic to be placed close to the host interface, reducing the need to burden the main microcontroller. The listed 4.6 ns pin-to-pin delay is suitable for many control and status paths, although high-speed differential USB routing remains the responsibility of the transceiver and PCB layout.
Recomendado
Programmable Test and Measurement Control
The XC2C64A-7VQ44I can coordinate instrument front-panel controls, relay sequencing, status decoding, and programmable test patterns. Its 45 user I/O pins support multiple control and measurement points, while the grade-7 device and reported 5 ns propagation delay provide useful margin for digital sequencing. Place it between a controller and analog test circuitry, and use controlled output states during initialization. The exact package pinout, I/O standards, and timing must be checked in AMD DS311 before schematic capture is released.

Notas de diseño
Use the official VQ44 land pattern from AMD DS311 and confirm it against the physical device marking before releasing the PCB. The supplied summaries conflict between a 44-pin VTQFP and a 56-pin CSP description. Do not generate a footprint from the 6 x 6 mm and 0.50 mm pitch snippets alone, because package height, exposed-pad treatment, pin numbering, and land-pattern details can differ. Validate courtyard, solder-mask clearance, paste volume, and assembly tolerances with the selected distributor or manufacturer footprint.
Reserve the 1.8 V core rail and any independently powered I/O banks according to DS311. Place required decoupling capacitors adjacent to the relevant supply pins, keep the high-current return path continuous, and avoid routing sensitive clock or control nets beneath potential switching-node activity. Because the available timing information comes from distributor summaries, use the manufacturer timing tables for setup, hold, and clock-domain requirements rather than treating the listed 5 ns propagation delay as a complete timing specification.
Do not assume that the final ordering suffix is interchangeable across speed and temperature requirements. Grade 7 versus grades 6, 5, and 4 can change timing margin, while an I versus C suffix can affect environmental qualification. Before substituting any XC2C64A candidate, compare the exact ordering table, operating-temperature limits, pin table, supply limits, and device marking in DS311. A matching package name alone does not prove that the replacement is safe for the original production environment.
The supplied summaries describe the device as optimized for 1.8 V systems and quote a low quiescent-current feature, but the displayed current value has an ambiguous unit. Do not calculate battery life or thermal dissipation from that snippet. Obtain the quiescent-current and active-current limits from AMD DS311, then estimate power with the worst-case supply, I/O activity, and temperature. Account for regulator efficiency and the board's supported load state when comparing grade or suffix alternatives.
