XC95144-7PQ160C

Complex Programmable Logic Devices Overview

The XC95144-7PQ160C is a complex programmable logic device (CPLD) from the Xilinx 9500 family, manufactured by AMD. It features 14,400 system gates and utilizes In-System Programmability (ISP) via JTAG. The device operates with a maximum propagation delay of 7 nanoseconds in the -7 speed grade. It is housed in a 160-pin PQFP package, providing extensive I/O capabilities for digital logic applications requiring non-volatile configuration and high-density integration.

Complex Programmable Logic Devices Part Context

This component belongs to the Xilinx 9500 series of CPLDs, which were among the first to offer ISP capabilities. The XC95144 variant specifically provides a balance of density and performance, serving as a drop-in replacement for GALs and PALs in legacy designs while offering reprogrammability advantages over fixed logic devices.

Complex Programmable Logic Devices Replacement Considerations

Compatible alternatives within the same family include the XC95144-7PQ100C and XC95144-7TQ144C, differing primarily in package type and pin count. Cross-family migration to newer Xilinx Spartan or Artix series requires significant design restructuring due to architectural differences.
