XC9536XL-10VQG44I CPLD - High-Performance Programmable Logic Device by Xilinx
The XC9536XL-10VQG44I from Xilinx represents the cutting edge of Complex Programmable Logic Device (CPLD) technology. This high-performance device features 36 macrocells with 800 equivalent gates, delivering exceptional logic density in a compact 44-pin TQFP package. With a propagation delay of just 10ns and operating voltage range of 3.0V to 3.6V, this CPLD offers the perfect balance of speed and power efficiency for demanding applications. The device supports in-system programming (ISP) with a minimum of 10,000 program/erase cycles, enabling flexible design iterations and field updates. Its industrial temperature range (-40 C to +85 C) ensures reliable operation in harsh environments.
Engineers will appreciate the XC9536XL-10VQG44I's advanced architecture that includes two function blocks with 18 macrocells each. Each macrocell can be individually configured for combinatorial or registered operation, providing tremendous design flexibility. The device features 34 user I/O pins with programmable slew rate control and individual output enable, allowing for optimal signal integrity in diverse system environments. Advanced power management features include programmable low-power modes that reduce current consumption by up to 50% during periods of reduced activity. The 10x10mm package makes this CPLD ideal for space-constrained applications while maintaining excellent thermal characteristics.
The XC9536XL-10VQG44I offers several technical advantages that set it apart from competing CPLDs. Its fast pin-to-pin delays of 10ns enable high-speed system operation, while the predictable timing model simplifies design verification. The device incorporates advanced security features including a programmable security bit that prevents unauthorized access to the configuration data. Designers can leverage the device's global clock and asynchronous reset resources to implement synchronous designs with minimal timing constraints. The architecture supports wide fan-in logic functions (up to 36 product terms per macrocell), reducing the need for logic level translation and improving overall system performance.
This versatile CPLD finds applications across multiple industries, including telecommunications, industrial control, and consumer electronics. In telecom systems, it's ideal for protocol bridging, interface conversion, and glue logic implementation. Industrial applications benefit from its robust design for motor control, sensor interfacing, and programmable logic replacement. Consumer electronics designers use it for display controllers, input processing, and system management functions. The device is particularly valuable in applications requiring quick time-to-market, as its programmable nature allows for design changes without hardware modifications. Common implementations include state machine control, address decoding, bus interfacing, and timing generation.
Xilinx provides comprehensive development support for the XC9536XL-10VQG44I through its industry-standard design tools. The ISE WebPACK software offers a complete development environment for design entry, synthesis, and device programming. Hardware debugging is facilitated through the device's support for boundary scan testing (IEEE 1149.1 JTAG). For production programming, Xilinx offers both standalone programmers and automated programming solutions. The device is fully supported by Xilinx's quality and reliability programs, with typical FIT rates below 50, making it suitable for mission-critical applications.
