XCR3064XL-10VQ44I: High-Performance CPLD by AMD Xilinx | Embedded Logic Solution

The XCR3064XL-10VQ44I from AMD Xilinx is a cutting-edge Complex Programmable Logic Device (CPLD) engineered for high-speed, low-latency embedded applications. With 64 macrocells and 4 logic blocks, this device delivers 1500 equivalent gates, making it perfect for designs requiring dense logic integration. Its in-system programmability (ISP) supports over 1,000 program/erase cycles, enabling field updates without hardware changes. Operating at 2.7V 3.6V, it achieves a remarkable propagation delay of just 9.1ns, ensuring real-time performance for critical systems. The 44-VQFP package (10x10mm) offers a compact footprint, while 36 I/O pins provide versatile connectivity. Industrial-grade temperature tolerance (-40 C to 85 C) ensures reliability in harsh environments.

This CPLD excels in logic consolidation, replacing multiple discrete ICs with a single reconfigurable solution. Key features include a deterministic timing model for predictable performance, non-volatile configuration memory for instant-on operation, and low-power consumption (typical ICC of 10mA at 3.3V). The XCR3064XL-10VQ44I supports JTAG boundary scan (IEEE 1149.1) for simplified testing and integrates advanced pin-locking architecture for design flexibility. AMD Xilinx's proven CMOS technology guarantees high noise immunity and long-term availability, backed by industry-leading development tools like ISE WebPACK.

Applications span industrial automation (PLC I/O control, sensor interfacing), telecommunications (protocol bridging, signal conditioning), and consumer electronics (display controllers, input processing). Automotive designs leverage its robustness for ECU glue logic, while medical devices utilize its reliability for safety-critical functions. The device's mix of speed (fMAX of 100MHz) and density efficiently implements state machines, address decoders, and bus interfaces. Compared to FPGAs, it offers lower static power and simpler timing closure ideal for medium-complexity fixed-logic applications.

Designers choose the XCR3064XL-10VQ44I for its optimal balance of cost, power, and performance in CPLD applications. The architecture features parallel processing with 5ns pin-to-pin delays, far outperforming microcontroller-based solutions. Each macrocell includes programmable XOR gates for efficient arithmetic operations and dense product-term allocation (up to 56 per output). Security features include bitstream encryption to protect IP. Available in lead-free (Pb-free) packaging, it meets RoHS compliance for global deployment. Reference designs and migration paths from older XC9500XL series simplify upgrades.

AMD Xilinx provides comprehensive development support including schematic libraries, HDL examples, and power estimation tools. The device is footprint-compatible with other 44-VQFP CPLDs, enabling design reuse. For volume production, programmable ROM options reduce BOM costs. As an active product with a 10-year longevity commitment, the XCR3064XL-10VQ44I remains a future-proof investment for embedded control systems requiring reliable, reprogrammable logic.
