XC2C64A-7VQ100I - 64-Macro-Cell 1.8V CPLD | AMD Xilinx
N.º de pieza: XC2C64A-7VQ100I ✗ Fin de vidaXC2C64A-7VQ100I Descripción general
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.

Aplicaciones típicas
XC2C64A-7VQ100I es adecuado para 6 aplicacións: Industrial Control Interface Logic, Data-Acquisition Front End, Telecommunications Interface Logic, Instrumentation and Measurement Control, Embedded System Glue Logic, Portable and Battery-Powered Equipment.
Industrial Control Interface Logic
The XC2C64A-7VQ100I fits compact industrial-control interfaces that require deterministic programmable interconnect and 64 macro cells without the resource density of an FPGA. Its 159 MHz -7 speed class and 4.6 ns listed pin-to-pin logic delay can support controller-facing logic, interlocks, state machines, and signal conditioning. The 1.8 V core matches systems designed around modern low-voltage digital rails. Place the CPLD between a controller and field-facing interface logic, then validate timing over the full -40 °C to +85 °C industrial temperature range associated with the I grade. Because the exact device is obsolete, new production should include a qualified same-footprint redesign path before layout signoff.
Recomendado
Data-Acquisition Front End
The XC2C64A-7VQ100I is suitable for coordinating data-acquisition channels, sampling control, trigger multiplexing, and sensor-interface timing. Its 64 macro cells and 1.5K-gate capacity are appropriate for several small state machines and protocol-level helpers rather than a large processing fabric. The -7 grade offers a published 159 MHz system frequency and a 4.6 ns listed logic delay, allowing timing-critical sequencing to be placed close to the acquisition converter. Keep analog and digital return paths separated, use the manufacturer grounding and decoupling guidance, and validate trigger jitter at the system level. An obsolete-device supply arrangement should be established before committing new production tooling.
Recomendado
Telecommunications Interface Logic
The XC2C64A-7VQ100I can implement line-interface adaptation, framing logic, clock-domain-support functions, and deterministic status sequencing in compact telecommunications equipment. Its 0.18 µm CMOS CoolRunner-II architecture provides nonvolatile configuration, while the 100-pin VTQFP package exposes enough connections for parallel data buses and control signals. The 159 MHz published system frequency makes the part relevant for multi-megabit serialization support and clocked control logic, although actual throughput depends on the selected I/O implementation and timing path. Keep clock routing short, provide continuous ground-plane return, and isolate switching supplies from sensitive pins. For new carrier equipment, confirm lifecycle continuity and update the design to a currently supported device family.
Recomendado
Instrumentation and Measurement Control
The XC2C64A-7VQ100I is useful in instrumentation where front-panel control, trigger sequencing, status decoding, and data routing must be combined in a small programmable-logic device. The 64 macro cells can consolidate deterministic control paths around an analog-to-digital converter, display interface, or communications controller. Its 1.8 V core reduces supply complexity in mixed-signal systems, while the -7 speed grade supports timing-sensitive sequencing at up to the published 159 MHz class. Preserve analog isolation, use separate quiet and noisy ground regions where appropriate, and verify acquisition-trigger jitter rather than relying only on the maximum clock frequency. Since the device is obsolete, production planning should include traceability and a tested migration option.
Recomendado
Embedded System Glue Logic
The XC2C64A-7VQ100I consolidates protocol conversion, bus arbitration, address decoding, and timing assistance between a microcontroller and peripheral devices. With 64 macro cells and approximately 1.5K gates, it fits multi-function glue logic better than a very large FPGA and offers more flexibility than fixed-function logic. The -7 grade provides a 159 MHz published class for synchronous interfaces, while the 100-pin VTQFP package supports a substantial pin complement on a compact board. Route interface standards through consistent termination networks, assign unused pins according to the manufacturer table, and perform post-layout timing checks. For a new embedded platform, validate the obsolete status before committing and preserve the footprint for a controlled migration.
Recomendado
Portable and Battery-Powered Equipment
The XC2C64A-7VQ100I can implement low-power control functions in portable instruments, battery-operated test equipment, and compact embedded products where nonvolatile configuration avoids an external configuration loader. Its 1.8 V core is compatible with low-voltage system rails, and the 64 macro cells are sufficient for wake-up sequencing, status logic, and peripheral multiplexing. The listed 15 A quiescent-current claim is ambiguous and should not be used for power budgeting without checking the manufacturer electrical table. Measure standby current across the complete design, isolate switched loads, and avoid unnecessary high-speed clocking in sleep states. Legacy sourcing should be planned carefully because the device is no longer manufactured.

Notas de diseño
Use the 100-pin VTQFP land pattern and pin-one orientation defined by AMD DS311 rather than relying on third-party package images. Secondary listings for this legacy device incorrectly identify smaller CSP packages, which can lead to an incorrect footprint. Confirm that the PCB exposes all required power, ground, configuration, clock, and I/O pins before substitution. Place every decoupling capacitor directly between the corresponding power and ground pins, using the shortest possible traces and solid ground-plane return paths.
Treat the 159 MHz system frequency as a device-class value rather than a guarantee for every implemented path. Analyze the slowest macro-cell-to-macro-cell and I/O paths with the actual package and I/O assumptions used in the design. Maintain a continuous ground reference beneath the device, avoid routing clocks over split planes, and use series damping only after simulating or measuring the actual edge rate. When evaluating a -6 or -5 replacement, rerun static timing analysis rather than assuming the -7 design margin transfers directly.
Do not treat the I and C suffix designations as interchangeable for industrial products. The target uses an industrial temperature-grade designation, while a commercial-grade candidate can fail environmental requirements even though its speed grade, pin count, and package match. Also distinguish the XC2C64A family from the non-A XC2C64 family; confirm configuration behavior, pin functions, and timing from DS311. A physical fit is necessary but does not by itself establish functional or qualification equivalence.
Check the core and I/O supply requirements separately in the manufacturer electrical-characteristics table because a 1.8 V core does not imply every I/O rail uses the same voltage. Keep the 1.8 V rail quiet and decouple it independently from switching supplies where the board architecture permits. Because one listing renders the quiescent-current claim ambiguously as 15 A, do not use that value for battery or thermal design. Measure current from the assembled board and use the manufacturer table for the selected temperature and speed grade.
Información de cumplimiento
The CoolRunner-II CPLD is not an automotive power device, so AEC-Q100 is treated as not applicable. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require current manufacturer or lot documentation.
