XC2C64A-5QFG48C - 64-Macrocell 1.8V CPLD | AMD Xilinx
N.º de pieza: XC2C64A-5QFG48C ✗ Fin de vidaXC2C64A-5QFG48C Descripción general
A CPLD is a programmable logic device that retains its configuration in nonvolatile memory and combines configurable logic with dedicated input and output resources. In the device hierarchy, a CPLD sits between simple programmable logic and an FPGA: it offers faster deterministic routing for moderate logic-density designs while providing nonvolatile configuration, lower system complexity, and a familiar PCB footprint.
The XC2C64A family provides up to 4.6 ns pin-to-pin logic delays and supports 1.8 V systems. Its low 15 A quiescent current is suitable for power-conscious embedded equipment. In-system programming allows configuration or field updates without removing the device from its circuit, while the 64-macrocell architecture accommodates control logic, interface adaptation, state machines, and fixed-footprint hardware customization.
The 0.18 µm CMOS implementation combines nonvolatile configuration storage with deterministic CPLD timing. The -5 suffix identifies a particular speed grade, while QFG48C identifies the 48-lead QFN exposed-pad package and commercial temperature designation. The exposed pad supports heat transfer from the device to the PCB, making copper placement and thermal analysis important in compact embedded systems.
Typical applications include industrial control, embedded instrumentation, communications-interface adaptation, low-voltage consumer electronics, and compact control systems. A 37-I/O device can connect processors, sensors, memory interfaces, status indicators, and discrete I/O when the design does not require the capacity or routing flexibility of a larger FPGA.
The primary design consideration is maintaining a clean 1.8 V rail and providing adequate thermal copper beneath the exposed pad. Confirm timing constraints for every external path, reserve configuration pins for their designated functions, and validate all I/O standards against the AMD DS311 device data sheet before layout release.

Aplicaciones típicas
XC2C64A-5QFG48C es adecuado para 6 aplicacións: Industrial Control Logic, Embedded Instrumentation, Communication Interface Adaptation, Low-Voltage Consumer Electronics, Sensor and I/O Hub, Compact Control System.
Industrial Control Logic
The XC2C64A-5QFG48C fits compact industrial-control boards that need deterministic logic without the routing overhead of a large FPGA. Its 64 macrocells and 37 I/O can implement state machines, interlocks, alarm logic, and interface conditioning, while the 263 MHz performance supports short combinational paths and responsive control sequences. The 1.8 V core aligns with modern 1.8 V processors and transceivers. Keep the exposed pad connected to a solid thermal and ground plane, and use the AMD DS311 timing tables to confirm every external path against the selected I/O standard.
Recomendado
Embedded Instrumentation
The XC2C64A-5QFG48C is useful in embedded instruments that require sensor conditioning, acquisition sequencing, and control of mixed-signal front ends. Its 37 I/O can support digital sensors, status LEDs, front-panel controls, and communication links, while 64 macrocells provide enough logic for command decoding and timing-state management. The 1.8 V supply reduces level-shifting complexity in modern systems, and the 15 A quiescent current suits power-sensitive equipment. Validate input thresholds, output slew behavior, and setup-time requirements against the actual external clock and bus speed before release.
Recomendado
Communication Interface Adaptation
The XC2C64A-5QFG48C can bridge unmatched digital interfaces in communications equipment by translating signal formats, inserting protocol timing, and routing control signals. Its 37 I/O provide substantial parallel connectivity for status, chip-select, interrupt, and data paths, while the 4.6 ns pin-to-pin delay capability supports faster deterministic logic paths. The device's 1.8 V core is well matched to contemporary interface ICs. Because legacy CPLD I/O characteristics depend on the selected bank and timing mode, confirm voltage compatibility, drive strength, and timing against every connected component.
Recomendado
Low-Voltage Consumer Electronics
The XC2C64A-5QFG48C is appropriate for low-voltage consumer products requiring fixed, compact logic functions such as mode control, display sequencing, button decoding, or peripheral arbitration. Its 1.8 V core minimizes power and integration overhead, while 64 macrocells and 37 I/O cover moderate control logic without occupying a large board area. The 15 A quiescent current is particularly useful in battery-oriented designs, although total standby consumption also depends on external pull states and the configured I/O bank. Preserve the exposed-pad thermal path even in compact enclosures where internal heat dissipation is limited.
Recomendado
Sensor and I/O Hub
The XC2C64A-5QFG48C can serve as the coordination hub for a board containing sensors, discrete I/O, and a host processor. Its 37 I/O support sensor inputs, interrupt routing, actuator-control signals, and status LEDs, while the programmable macrocells implement filtering, debouncing, scaling, and sequencing logic. At 1.8 V, the CPLD can share a rail with compatible low-voltage sensors and processors, although each I/O still requires voltage-domain verification. Use short, well-grounded tracks for sensitive inputs, place input conditioning near the source, and test all unused pins in the configuration used by the production design.
Recomendado
Compact Control System
The XC2C64A-5QFG48C supports compact control systems where deterministic logic, nonvolatile configuration, and a small pin count matter more than programmable-logic capacity. It can implement sequencers, protection logic, watchdog handling, and peripheral selection around a microcontroller or processor. The 48-pin QFN exposed-pad package reduces board area, and in-system programming simplifies configuration maintenance. The footprint must still support reliable assembly and heat flow, so provide the exposed-pad copper and thermal vias recommended by AMD and verify pin assignments against the package drawing rather than inferring them from the family suffix alone.

Notas de diseño
Treat the exposed pad as both a thermal path and a layout-critical feature. Provide uninterrupted ground copper beneath the package, follow the AMD package drawing for pad dimensions, and place thermal vias where they can transfer heat without violating manufacturing rules. The heat-flow requirement is especially important because the QFN-48 body has no large exposed leads for mechanical or thermal transfer. Validate the completed board under worst-case ambient temperature and operating activity rather than relying on ambient-temperature calculations alone.
Assign configuration, supply, ground, and user I/O pins strictly from the AMD DS311 pin-description table for the selected QFG48 variant. Keep configuration paths short and away from high-speed or switching nodes, and route ground returns directly to the exposed-pad plane. Because the package has 37 user I/O in a 48-lead footprint, several leads carry mandatory power, ground, or configuration functions; using a generic 48-pin symbol can cause incorrect schematic-to-layout assignments.
Do not assume that every XC2C64A-7QFG48C or alternate-speed device is an unconditional electrical replacement for the -5 grade. The -7QFG48C operates at 159 MHz compared with 263 MHz for the target, so slower paths may still meet the original clock period while critical paths may not. Re-run static timing analysis with the actual external delays, and verify configuration pin states, supply sequencing requirements, and unused-pin treatment before approving a substitution.
Apply the AMD-recommended I/O timing and drive assumptions to every external interface. For slow control signals, place pull resistors at the appropriate device or source to prevent floating inputs during configuration or reset. For interfaces connected to higher-speed devices, account for board capacitance, connector or package delay, ringing, and the selected I/O standard in the timing budget. Do not infer edge rates solely from the 263 MHz device speed because package and board paths can dominate short critical paths.
Información de cumplimiento
RoHS-compliant and lead-free status are identified for the XC2C64A-5QFG48C. The device is a commercial-grade CPLD, so AEC-Q100 automotive qualification is not applicable. Exact-lot REACH, halogen-free, and conflict-minerals declarations require supplier confirmation.
