XC95144XL-7TQG144I

Complex Programmable Logic Devices Overview

The XC95144XL-7TQG144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, designed for 3.3V low-voltage systems. It features 144 macrocells and approximately 3,200 usable gates distributed across eight Function Blocks. The device operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum operating frequency of 178 MHz and a typical propagation delay of 7.5 ns. Packaged in a TQFP-144 format, it supports industrial temperature ranges from -40°C to +85°C and utilizes Flash memory for non-volatile configuration.

Complex Programmable Logic Devices Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or alternative suppliers holding remaining stock. Verification of part authenticity and storage conditions is critical due to the component's age and potential moisture sensitivity.

Complex Programmable Logic Devices Selection Notes

Select this model when a 3.3V CPLD with 144 macrocells and TQFP-144 packaging is required. Ensure the design accounts for the 7.5 ns propagation delay and 178 MHz internal clock limit. Verify that the application environment stays within the -40°C to +85°C operating temperature range and that 5V tolerant I/O interfaces are necessary for peripheral connectivity.

Complex Programmable Logic Devices Part Context

The XC95144XL-7TQG144I belongs to the XC9500XL series, which succeeded the original XC9500 line with improved performance and lower power consumption. It is part of AMD/Xilinx's portfolio of high-performance CPLDs, offering a balance of density and speed for embedded logic applications before the widespread adoption of smaller FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to the obsolete status. Consider evaluating newer Xilinx/AMD CPLD families such as the XC9500XV or XC9536XL if higher density or different package options are acceptable. Cross-reference with other manufacturers like Lattice for equivalent macrocell counts and I/O configurations.
