XC2C64A-7PC44C - 64-Macrocell 159MHz CPLD | AMD
Артикул: XC2C64A-7PC44C ✗ Снят с производстваXC2C64A-7PC44C Обзор
A CPLD is a user-programmable digital logic device that combines nonvolatile configuration storage with deterministic logic structures. Unlike a mask-programmed fixed ASIC, a CPLD can be reprogrammed during development or field updates. The CoolRunner-II family also uses low-power design features and interconnected architecture to support portable equipment, industrial controls, communications equipment, and general-purpose embedded systems.
The XC2C64A offers 64 macrocells for implementing combinational and sequential logic. According to the AMD CoolRunner-II XC2C64A data sheet, DS311, the device uses 0.18 µm CMOS technology and supports a 1.8 V core voltage. The -7 designation identifies the performance-grade option, while the PC44 suffix identifies the commercial-temperature 44-pin package configuration. The package is designed for surface-mount PCB assembly.
The device is useful when design requirements are stable but not sufficiently large to justify an FPGA. Its macrocell-based logic and dedicated I/O structures provide a practical platform for state machines, bus arbitration, protocol bridges, keypad scanning, display control, and glue logic. Because the configuration is retained in nonvolatile memory, the implemented logic remains available after power is removed and restored.
Typical implementations include industrial controller front ends, portable instrument interfaces, communications equipment, embedded control logic, and compact consumer products. Design teams can use the same 44-pin footprint for equivalent CoolRunner-II sourcing options while preserving the programmed bitstream, provided the replacement suffix and electrical conditions have been checked against DS311.
Careful hardware design begins with the device pinout, power architecture, and termination requirements in DS311. Confirm all 44 package contacts, supply connections, and I/O standards on the current pin-description table before routing the PCB. Treat the configuration interface and JTAG behavior as critical design constraints because incorrect pin assignment or signal conditioning can prevent programming even when the rest of the logic is electrically correct.
This page combines the device identity, manufacturer documentation, package information, sourcing references, same-footprint alternatives, and practical engineering guidance. It focuses on the decisions an engineer must make before programming or qualifying the XC2C64A-7PC44C in production equipment.

Типичное применение
XC2C64A-7PC44C подходит для 6 применениеs: Industrial Controller Front End, Portable Instrument Interface, Communications Equipment Glue Logic, Embedded System Peripheral Control, Display and Keypad Controller, Legacy Control-System Retrofit.
Industrial Controller Front End
The XC2C64A-7PC44C suits compact industrial control logic where 64 macrocells can implement state machines, discrete signal conditioning, and supervisory functions. Its 159 MHz performance rating provides timing margin for synchronous control paths, while the 1.8 V core simplifies compatibility with modern controller rails. The 44-pin PLCC package also keeps the external footprint manageable on a densely populated control board. However, the commercial suffix requires the completed assembly to remain inside the device’s specified temperature range. Before final qualification, review the exact pin table, supply requirements, and environmental limits in DS311 rather than assuming that another XC2C64A suffix has identical commercial-temperature behavior.

Portable Instrument Interface
The XC2C64A-7PC44C can connect sensors, switches, displays, and a host processor in a portable measurement instrument. Its 64 macrocells are suitable for sampling control, calibration tables, status encoding, keypad scanning, and bus arbitration, while the 159 MHz device rating supports deterministic multi-clock logic. Nonvolatile configuration is particularly useful in portable equipment because it avoids repeating a firmware-loading sequence after every power cycle. Board-area savings come from the 44-pin PLCC package, but assembly density and exposed underside access must be considered. Validate low-power requirements against the exact electrical tables and use an industrial-grade alternative only when the product’s ambient-temperature budget requires it.

Communications Equipment Glue Logic
The XC2C64A-7PC44C is appropriate for communications equipment requiring deterministic protocol translation, framing logic, FIFO control, and status multiplexing. The 64 available macrocells allow several related finite-state machines to coexist, and the 159 MHz performance class can support demanding clock-domain and data-path tasks when timing closure permits. Nonvolatile configuration also supports field-identifiable equipment behavior across power cycles. The 44-pin PLCC package makes the CPLD practical for established communication boards, although I/O count and supported standards must be checked against the specific architecture. Because the device family is legacy, a current low-power or higher-capacity programmable device may be preferable for new communication platforms with long lifecycle commitments.

Embedded System Peripheral Control
The XC2C64A-7PC44C can serve as a deterministic peripheral controller between a processor and discrete hardware. Typical assignments include address decoding, interrupt arbitration, watchdog sequencing, reset coordination, and programmable I/O expansion. A 159 MHz performance rating gives designers margin above slower glue-logic approaches, while the 64-macrocell limit keeps the design compact and easy to partition. The 1.8 V core operation aligns with many contemporary processor systems, although all interface levels must be checked against the supported I/O standards. The PLCC footprint supports established assembly flows but is larger than many fine-pitch alternatives. For new embedded platforms, compare that legacy footprint and lifecycle burden against current CPLD options.

Display and Keypad Controller
The XC2C64A-7PC44C is well suited to scanning a keypad, multiplexing display segments, debouncing inputs, and coordinating interrupts with a host processor. These tasks fit naturally within 64 macrocells, and the 159 MHz rating provides ample timing margin for parallel display multiplexing and synchronous serial interfaces. Nonvolatile configuration preserves the controller personality between power cycles, simplifying boot behavior in appliances and instruments. The 44-pin PLCC package provides a practical pin count for common control buses and discrete I/O, provided the design does not require more signals than the device offers. Verify available I/O, electrical thresholds, and timing limits in DS311 before assigning every display and keypad signal.

Legacy Control-System Retrofit
The XC2C64A-7PC44C is relevant to maintenance and retrofit programs that need to reproduce an existing 44-pin CPLD design without changing its board layout. The 64 macrocells, 159 MHz rating, and 1.8 V core make the same-family ordering codes useful candidates for controlled substitution, provided their suffix, temperature classification, and assembly details are reviewed. An industrial-temperature option may extend qualification flexibility, but it does not change the fundamental logic architecture. Because the original CoolRunner-II generation has reached end of life, successful replacement also depends on access to the programmed configuration file, compatible programming hardware, and a verified software toolchain. Escalate long-term supply and obsolescence risk rather than treating a mechanical substitution as a complete lifecycle solution.

Заметки по проектированию
Use the 44-pin PLCC land pattern and pin numbering from DS311 when laying out the PCB. Confirm whether the footprint requires a center thermal or electrical pad and verify the assembly process’s solder-profile requirements. Do not substitute the 44-pin VQFP footprint for the PLCC version because their lead arrangements and courtyard geometry differ even though both use 44 contacts.
Follow the exact supply-pin, decoupling, and voltage-tolerance requirements in DS311. The confirmed core voltage is 1.8 V, but capacitor values, allowable ripple, and input-current limits must not be inferred from another package option. Place required bypass components adjacent to their power pins and provide a low-impedance return path to minimize supply disturbance during configuration and switching activity.
Treat the ordering suffix as part of the design specification. XC2C64A-7PC44C, XC2C64A-7PCG44C, and industrial I-suffix variants share important family characteristics but may differ in assembly configuration or temperature classification. Before substitution, compare the complete MPN against the approved parts list, temperature requirements, assembly instructions, and the latest manufacturer documentation.
Separate programming and JTAG signals from sensitive or high-speed routing where practical, and provide the interface levels required by the selected programming hardware. Use the manufacturer pin-description table to identify every configuration and clock connection. Review timing constraints in the design tool because the 159 MHz figure is a device performance rating rather than a guarantee that every implemented path closes at that frequency.
Информация о соответствии
No explicit environmental or substance-compliance declaration was identified for the exact ordering code. AEC-Q100 is not applicable because this is a programmable logic device rather than an automotive-qualified semiconductor orderable.
