XC95144XL-7CSG144I

Complex Programmable Logic Devices Overview

The XC95144XL-7CSG144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 144-pin CSBGA package. It operates at a 3.3V supply voltage and features 144 macrocells organized into eight Function Blocks. The device provides approximately 117 user I/Os and supports In-System Programming (ISP) via IEEE 1149.1 JTAG boundary scan. The -7 speed grade indicates a maximum operating frequency of 142.8 MHz with a typical I/O to output delay of 7.0 ns. This non-volatile Flash-based component is designed for high-density logic applications requiring reprogrammability.

Complex Programmable Logic Devices Procurement Notes

The XC95144XL-7CSG144I has been officially discontinued by AMD. Final order dates were set for June 2024, with final deliveries concluding in December 2024. Current availability is restricted to existing stock or secondary market sources. Verification of authenticity and lot traceability is critical when sourcing from non-primary distributors due to the end-of-life status.

Complex Programmable Logic Devices Selection Notes

Designers should consider the -7 speed grade timing constraints, specifically the 7.0 ns max propagation delay, when targeting high-frequency designs. The CSBGA-144 package requires appropriate PCB layout considerations for thermal dissipation and signal integrity. As a 3.3V core device with 5V tolerant I/Os, ensure power sequencing adheres to datasheet specifications to prevent latch-up or configuration errors during power-up.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, which succeeded the original XC9500 and XC9500XV lines. While the broader XC9500 family offered various voltage cores (5V, 2.5V, 3.3V), the XL variant specifically targets 3.3V systems. The discontinuation of this series marks the end of production for this specific generation of Flash-based CPLDs, shifting focus toward newer FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-to-pin replacements may require evaluating newer Xilinx Artix or Spartan FPGA families, though these involve architectural differences and potential design modifications.
