The FastFLASH XC9500XL family is a 3.3V CPLD family targeted for high-performance, low-voltage applications in leading-edge communications and computing systems, where high device reliability and low power dissipation is important. Each XC9500XL device supports in-system programming (ISP) and the full IEEE Std 1149.1 (JTAG) boundary-scan, allowing superior debug and design iteration capability for small form-factor packages. The XC9500XL family is designed to work closely with the Xilinx® Virtex®, Spartan®-XL and XC4000XL FPGA families, allowing system designers to partition logic optimally between fast interface circuitry and high-density general purpose logic. The XC9500XL family members are fully pin-compatible, allowing easy design migration across multiple density options in a given package footprint.
The XC9500XL architectural features address the requirements of in-system programmability. Enhanced pin-locking capability avoids costly board rework. In-system programming throughout the full commercial operating range and a high programming endurance rating provide worry-free reconfigurations of system field upgrades. Extended data retention supports longer and more reliable system operating life.
Advanced system features include output slew rate control and user-programmable ground pins to help reduce system noise. Each user pin is compatible with 5V, 3.3V, and 2.5V inputs, and the outputs may be configured for 3.3V or 2.5V operation. The XC9500XL device exhibits symmetric full 3.3V output voltage swing to allow balanced rise and fall times.
