XC2C64A-7VQ100C - 64-Macro-Cell 1.8V CPLD | AMD
N.º de pieza: XC2C64A-7VQ100C ✗ Fin de vidaXC2C64A-7VQ100C Descripción general
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.

Aplicaciones típicas
XC2C64A-7VQ100C es adecuado para 6 aplicacións: Industrial Automation Control, Telecommunications Interface Bridging, Embedded System Bus Decoding, Consumer Equipment Control, Programmable Signal Conditioning, Legacy Platform Lifecycle Extension.
Industrial Automation Control
The XC2C64A-7VQ100C fits compact machine-control logic where a 1.8 V supply, 64 macro cells, and 45 user I/Os are sufficient. It can implement state machines, interlocks, sensor conditioning logic, actuator command decoding, and communication-protocol interfaces without using a large FPGA. The nonvolatile configuration allows the controller to recover its programmed function after power restoration. Designers should confirm the commercial temperature range, external interface timing, and I/O loading against DS311 before deployment in an industrial enclosure.
Recomendado
Telecommunications Interface Bridging
The XC2C64A-7VQ100C is appropriate for line-card glue logic that converts between parallel control signals, status registers, and serialized communication paths. Its 64 macro cells provide deterministic combinational and registered logic, while the listed 45 user I/Os support multi-bit buses. At a 1.8 V core supply, the device can sit alongside low-voltage communications circuitry, but external line drivers and level translators remain necessary for physical interfaces. Validate setup and hold timing, I/O standards, and board-level signal integrity against the system clock requirements.
Recomendado
Embedded System Bus Decoding
A CPLD is useful when a processor requires flexible address decoding, interrupt qualification, latch functions, or peripheral select logic. The XC2C64A-7VQ100C provides 64 macro cells and 45 user I/Os for implementing these functions in a deterministic package smaller than a general-purpose FPGA. Its nonvolatile configuration simplifies field updates because the logic file is retained in the device. The implementation should include timing constraints for every registered path and should use the manufacturer pin table to assign clock, control, and I/O pins correctly.
Recomendado
Consumer Equipment Control
The XC2C64A-7VQ100C can consolidate front-panel control, display sequencing, keypad scanning, status indication, and mode-selection logic in compact consumer products. Its 1.5K gates and 64 macro cells suit small control blocks that do not justify an FPGA, and the 100-pin VTQFP package supports conventional surface-mount assembly. The commercial-grade ordering code requires verification against the intended ambient range. Designers should also budget decoupling capacitance, provide a stable 1.8 V supply, and avoid using unverified I/O modes for externally accessible signals.
Recomendado
Programmable Signal Conditioning
The XC2C64A-7VQ100C can implement programmable delay, pulse qualification, edge alignment, and signal-format normalization between fixed-function logic blocks. Its 6.7 ns listed propagation delay and -7 speed class make it useful for moderate-speed control paths, although external synchronization requirements must be evaluated at the system level. Registered outputs and a low-jitter clock strategy can improve repeatability. Confirm I/O timing for every operating corner and use the JTAG programming interface only after the board's power and ground distribution have been validated.
Recomendado
Legacy Platform Lifecycle Extension
The XC2C64A-7VQ100C is relevant to maintenance of legacy platforms because AMD identifies the enhanced XC2C64A as a pin-for-pin replacement for members of the original XC2C64 family. An existing 100-pin board can therefore be evaluated for reuse with reduced redesign risk when speed, temperature, electrical limits, and configuration compatibility are confirmed. Compare the original and enhanced device data carefully rather than assuming identical timing or power behavior. This approach is especially useful when maintaining industrial or telecommunications equipment with a long service life.

Notas de diseño
Use the 100-pin VTQFP land pattern and 0.50 mm lead pitch specified in AMD datasheet DS311. Place the programmable device according to the manufacturer package drawing, preserve access to the JTAG and configuration pins, and orient the board so thermal and soldering processes do not conflict with fine-pitch leads. Verify pin-one marking during assembly inspection because incorrect orientation can permanently damage a programmable logic device.
The XC2C64A-7VQ100C is optimized for 1.8 V operation, so supply routing must remain consistent with the family electrical limits. Place local bypass capacitors at the supply pins, keep high-current return paths compact, and minimize voltage drop between the regulator and device. Use the recommended capacitor values and topology in DS311 rather than relying on a generic CPLD decoupling practice.
Separate programmable logic outputs from sensitive analog or high-speed inputs wherever possible, and assign clocks to pins identified in the manufacturer pin table. Maintain controlled return paths under clock and data routes, avoid routing JTAG signals adjacent to high-slew-rate outputs, and apply the device I/O specifications to each external signal. Review unused pins and configuration behavior explicitly during schematic and layout sign-off.
Do not treat all XC2C64A ordering codes as automatic substitutes. Speed-grade, temperature-grade, package, and marking suffixes affect qualification and electrical limits, while the XC2C64 to XC2C64A change also requires configuration and timing review. Compare the ordering tables, pin descriptions, power-up behavior, and AC timing in DS311 before approving a replacement. Preserve an archived configuration file for every board revision.
