XC2C64A-5VQ44C - 4.6ns 64-Macrocell CPLD | AMD
料号： XC2C64A-5VQ44C ✗ 停产XC2C64A-5VQ44C 概述
A CPLD is a programmable logic device that combines programmable AND/OR logic structures with non-volatile configuration memory. The XC2C64A belongs to the CoolRunner-II CPLD hierarchy, which sits between fixed-function logic and larger field-programmable gate arrays. It is useful when a design needs deterministic propagation timing, in-system reconfiguration, and a modest logic-cell count without the complexity of an FPGA or processor-based implementation.
The device provides 64 macrocells and approximately 1.5K gates according to the verified product data. Its 4.6 ns pin-to-pin delay supports moderate-speed control, decode, glue-logic, and interface tasks. The listed 333 MHz internal frequency provides additional timing context, while its optimized 1.8 V architecture targets modern low-voltage digital systems. A 15 A quiescent-current figure appears in the supplied specification extract, although the intended operating supply details should be confirmed in the manufacturer datasheet before power budgeting.
Typical uses include communications equipment, industrial automation, real-time signal processing, bus-interface control, data-capture front ends, and embedded control logic. The CPLD is particularly suitable for deterministic designs requiring several interconnected state machines, protocol converters, or glue-logic functions around microcontrollers and processors. Its macrocell architecture also allows designers to consolidate small controller sections into one programmable device rather than using several unrelated fixed-function ICs.
Designers should verify power-supply voltage, I/O standards, available package variants, and acquisition-file compatibility in the DS311 device documentation. PCB layouts should preserve adequate ground and power distribution, and unused inputs must be handled according to the manufacturer guidelines. This page synthesizes the supplied specifications, sourcing information, speed-grade alternatives, and design guidance into a compact engineering reference for the XC2C64A-5VQ44C.

典型应用
XC2C64A-5VQ44C 适用于 6 应用s: Communications Interface Control, Industrial Automation Controller, Real-Time Signal Processing, Bus Interface and Protocol Conversion, Custom Hardware Acceleration, Embedded Control and Sensor Interface.
Communications Interface Control
The XC2C64A-5VQ44C fits communications-interface control because its 64 macrocells can implement multiple protocol state machines, framing logic, and data-path glue functions while maintaining a 4.6 ns pin-to-pin delay. Engineers can place the CPLD between a transceiver or processor and peripheral logic to perform command decoding, byte alignment, or channel arbitration. The 44-pin VQFP package provides a compact surface-mount option for communications equipment where board area is constrained. The principal trade-off is finite macrocell capacity: wide parallel interfaces or deeply parallel datapaths must be mapped carefully against the approximately 1.5K-gate equivalent capacity. DS311 timing constraints and the target system clocking should be checked before implementation.
推荐
Industrial Automation Controller
The XC2C64A-5VQ44C is suitable for industrial automation logic that combines discrete controllers, interlocks, sequencing, and signal conditioning in a programmable device. Its 64 macrocells allow multiple small state machines to be consolidated, while the 4.6 ns delay supports deterministic control functions operating from an external clock. The CPLD can handle switch-debounce logic, pulse shaping, stepper sequencing, or safety-interlock decoding without relying entirely on firmware. The 44-pin VQFP package also supports compact controller boards. Because the verified data does not state the industrial temperature grade, operating range, isolation rating, or safety certification, engineers should not infer suitability for safety-critical machinery without checking the complete DS311 and qualification records.
推荐
Real-Time Signal Processing
The XC2C64A-5VQ44C can serve as the control and data-conditioning element in a real-time signal-processing pipeline because it combines a 4.6 ns pin-to-pin delay with programmable non-volatile logic. Suitable tasks include channel selection, trigger generation, sample-counter sequencing, clock-phase selection, and format conversion between a data source and a processor. The 64 macrocells make the device most valuable for control-plane logic surrounding higher-throughput DSP or FPGA functions, rather than for large waveform buffers or multiplier-heavy arithmetic. The 333 MHz internal-frequency figure provides useful timing context for design planning, but external interface timing must be evaluated against actual board-level clock and I/O constraints documented in DS311.
推荐
Bus Interface and Protocol Conversion
The XC2C64A-5VQ44C is well suited to protocol conversion and bus-interface glue because CPLD macrocells can implement fixed-width state machines, address decoding, arbitration, and data-format translation. A design can bridge a legacy peripheral interface to a parallel processor bus, generate chip-select timing, or isolate asynchronous handshakes. Its 4.6 ns logic delay helps preserve timing margin in moderate-frequency systems, while the 44-pin VQFP package limits board footprint. The 64-macrocell limit means designers should establish a conservative pin and logic budget before committing the design. Use the manufacturer's timing analyzer and DS311 electrical characteristics to validate every registered input, output enable, and feedback path rather than relying on nominal delay alone.
推荐
Custom Hardware Acceleration
The XC2C64A-5VQ44C can add compact hardware acceleration alongside a microprocessor or FPGA by implementing parallel compare, CRC-like, filtering, or data-shaping logic in a small CPLD. Its 64 macrocells provide deterministic combinational and sequential resources without the configuration and routing complexity of a much larger FPGA. The 4.6 ns pin-to-pin delay can support pipelined accelerator functions when the board clock is appropriately constrained. The 44-pin VQFP package enables the accelerator to fit into compact embedded systems. Designers must ensure that accelerator outputs meet downstream setup and hold requirements after adding PCB delay; synchronizing across clock domains or inserting registers may be necessary even when the nominal internal frequency appears sufficient.
推荐
Embedded Control and Sensor Interface
The XC2C64A-5VQ44C fits embedded control and sensor-interface tasks that require deterministic digital logic close to the sensor or actuator electronics. Examples include conditioning discrete sensor signals, sequencing ADC control lines, debouncing switches, generating motor-step sequences, and coordinating power-control signals. Its 64 macrocells allow several related functions to be consolidated, while the 4.6 ns delay provides short deterministic paths for sampled sensor events. The package is suitable for compact embedded boards, and the reported 15 A quiescent-current figure should be checked against the exact operating mode and supply condition before low-power battery designs are finalized. ESD protection, input thresholds, and voltage compatibility must be handled at the board level unless explicitly supported by the relevant device documentation.

设计说明
Design all external interfaces against the published worst-case timing constraints, not only the nominal 4.6 ns pin-to-pin delay. Register inputs and outputs where practical, constrain every clock, and include setup, hold, skew, and PCB-delay margins. The 333 MHz internal-frequency figure is not a guarantee that an unregistered external interface will operate at that rate. Use the DS311 timing models and the appropriate device speed grade during implementation.
Keep the VQFP power and ground connections close to their package pins and provide a low-impedance plane for every required supply. Route high-speed or edge-sensitive inputs away from switching nodes and noisy power inductors. The supplied sources do not provide the complete pin table, so verify programming, clock, ground, and I/O assignments in DS311 before releasing artwork; incorrect interpretation of the 44-pin footprint can prevent programming or damage adjacent circuitry.
Do not assume that every XC2C64A suffix is interchangeable. The -5, -6, -7, and -4 suffixes select speed grades, while ordering-code letters can encode package, temperature, or production attributes. Before substituting a candidate, compare the complete ordering code, footprint, pin definitions, temperature requirements, and acquisition file in the DS311 ordering guide. A shared 44-pin package alone does not prove drop-in equivalence.
The supplied specification extract lists 15 A quiescent current, but that figure requires clarification before it is used in a power budget because the source snippet does not provide its measurement conditions. Confirm the relevant supply, I/O state, frequency, and operating mode in DS311. Include configuration-pin pull states, I/O loading, and dynamic current in the worst-case supply design rather than relying only on a nominal quiescent-current number.
合规信息
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the legacy product generation or ordering suffix.
