A CPLD (Complex Programmable Logic Device) is a class of programmable logic IC that sits between simple SPLD devices such as GAL/16V8 parts and full FPGAs in the programmable logic hierarchy. CPLDs provide deterministic, pin-to-pin timing for glue logic, state machines, bus interfacing, and power-on configuration control, and are non-volatile - the design is retained through power cycles without external configuration memory.
Key features of the XC2C64A include the industry-leading 0.18 micron CMOS process optimized for 1.8 V systems, as low as 15 uA quiescent current, internal frequencies up to 333 MHz, and in-system programmability (ISP). The CoolRunner-II architecture delivers extremely low dynamic power because it uses a true 1.8 V core rather than 3.3 V or 5 V legacy cores, making it well suited to battery-powered and thermally constrained designs.
Technically, the XC2C64A provides 4 function blocks containing 16 macrocells each, supporting both combinational and registered logic with synchronous and asynchronous resets. The -5 speed grade offers 4.6 ns pin-to-pin delay and 263 MHz system toggle performance, with DataGate and CoolPower technologies further reducing active power. Schmitt-trigger inputs, optional dual-DATA-gate inputs, and 3.3 V-tolerant I/O standards through level-shifting ease mixed-voltage system integration.
Typical applications include glue logic consolidation in embedded systems, power-up sequencing and FPGA configuration control, address decoding, bus bridging, portable and battery-operated instrumentation, and industrial control boards where deterministic timing and non-volatile logic are required.
Design consideration: the 1.8 V core supply requires a clean, well-decoupled rail; I/O banks may interface to 3.3 V systems, but check the DS311 datasheet I/O standard selection in your tools before committing pin assignments.

典型應用
XC2C64A-5VQ100C 適用於 6 應用s: Glue Logic Consolidation, FPGA Configuration and Power-Up Sequencing Control, Battery-Powered Portable Instrumentation, Industrial Control and Address Decoding, Communication and Networking Interface Bridging, Prototype and Niche-Volume Embedded Boards.
Glue Logic Consolidation
The XC2C64A-5VQ100C replaces dozens of discrete 74-series logic devices with a single 64-macrocell, 1.8 V CPLD. With a 4.6 ns pin-to-pin delay in the -5 speed grade, it meets the timing budgets typically assigned to fast TTL/CMOS combinational paths, while 45 user I/O pins provide enough connectivity to absorb address decoding, chip-select generation, and bus buffering on one chip. Consolidation reduces board area, BOM count, and assembly cost, and the non-volatile flash-based design means no configuration time at power-up - logic is valid immediately, unlike an FPGA that must load a bitstream. The 1.8 V core also cuts dynamic power relative to 3.3 V or 5 V legacy SPLD solutions.
推薦
FPGA Configuration and Power-Up Sequencing Control
In multi-rail embedded systems, the XC2C64A-5VQ100C is frequently used as a sequencer that controls FPGA configuration, reset distribution, and power-good monitoring. Its non-volatile nature means sequencing logic is active from the instant power is applied, with no external configuration memory or load cycle, and the deterministic 4.6 ns pin-to-pin delay guarantees repeatable reset timing. The low 15 uA quiescent current keeps housekeeping power minimal in standby states. Typical circuits tie power-good comparators and reset-enabling signals into the CPLD macrocells, which then sequence enable pins across regulators, release processor resets, and drive the FPGA program/init handshake lines under HDL control via JTAG programming.
推薦
Battery-Powered Portable Instrumentation
The CoolRunner-II architecture is optimized for 1.8 V systems with quiescent current as low as 15 uA, making the XC2C64A-5VQ100C one of the lowest-power CPLDs available for portable and battery-operated equipment such as handheld meters, data loggers, and wireless sensor nodes. In these systems the CPLD provides interface expansion, keypad scanning, and display control logic that would otherwise keep an MCU awake and drain the battery. The VQG low-power variant with DataGate further trims dynamic I/O switching power by gating inactive outputs. The 100-pin TQFP package with 45 user I/Os offers high connectivity in a surface-mount footprint compatible with standard 0.5 mm pitch assembly processes.
推薦
Industrial Control and Address Decoding
Industrial controllers use the XC2C64A-5VQ100C for address decoding, I/O expansion, and deterministic interface logic between processors, memories, and peripherals. The 333 MHz internal frequency capability and 4.6 ns pin-to-pin delay handle fast bus cycles, while Schmitt-trigger inputs improve noise immunity in electrically harsh factory environments. Designs requiring extended ambient temperature ranges can specify the industrial-grade XC2C64A-5VQ100I, which is pin-to-pin identical and requires no PCB change. The non-volatile architecture also simplifies maintenance: field firmware for the CPLD is updated in-system through the JTAG port without removing the board from service.
推薦
Communication and Networking Interface Bridging
Networking line cards, backplane adapters, and communication modules use the XC2C64A-5VQ100C to bridge between bus standards, generate chip selects for PHY and MAC devices, and implement protocol-glue state machines. The 45 user I/Os and 4 function blocks provide enough density for simple serial-to-parallel converters, handshaking engines, and LED/status logic. Because the -5 speed grade delivers 4.6 ns pin-to-pin delay deterministically, interface timing analysis is straightforward - a key advantage over FPGA designs where routing delays vary. The 1.8 V core also helps meet system thermal budgets in densely packed switching equipment with limited airflow.
推薦
Prototype and Niche-Volume Embedded Boards
For prototypes, reference platforms, and low-to-medium volume boards, the XC2C64A-5VQ100C offers reprogrammable logic without FPGA cost and complexity. Designs are captured in VHDL or Verilog and compiled with the AMD/Xilinx ISE toolchain, then programmed over JTAG in seconds, enabling rapid iteration during bring-up. The 100-pin TQFP footprint is hand-solderable with standard equipment, unlike ball-grid packages, easing prototype rework. The non-volatile flash configuration means boards boot instantly with no configuration PROM, reducing BOM cost. When volume grows and density limits are reached, the same HDL often ports to a CoolRunner-II family member or an FPGA with minor changes.

設計說明
Provide a clean 1.8 V core rail within the 1.7 V to 1.9 V permitted range. Decouple with at least one 0.1 uF ceramic capacitor per power/ground pin pair placed within 2 mm of the device, plus 4.7 uF to 10 uF bulk capacitance near the package. The CoolRunner-II core draws as little as 15 uA quiescent, but dynamic I/O switching dominates real power draw, so size the regulator for peak simultaneous switching of the 45 user I/Os, not for static current. Avoid sharing the 1.8 V rail with noisy loads; a small ferrite bead in series is a low-cost improvement.
The VQ100 TQFP uses a 0.5 mm pitch - use standard 0.5 mm QFP land patterns per your PCB fabrication capability and inspect with magnification for solder bridging during hand assembly. Keep JTAG traces (TDI, TDO, TMS, TCK) short and add a series resistor (22 to 33 ohm) on TCK for signal integrity. Reserve the JTAG header on production boards for field updates, since the part is in-system programmable. Unused I/Os should be driven to a defined logic level in your HDL design rather than left floating, per CoolRunner-II design guidance.
Do not substitute the -7 speed grade into a board whose timing was verified at -5: the pin-to-pin delay rises from 4.6 ns to roughly 7 ns, which can break address-decode and bus-interface margins. Remember the original XC2C64 was discontinued (Xilinx notice XCN05017); only the enhanced XC2C64A is pin-for-pin orderable. Verify I/O bank voltage constraints in the ISE pin planner before routing 3.3 V-tolerant interfaces, and never exceed datasheet I/O standard voltage limits when interfacing mixed-voltage systems.
