XC95144XL-7TQ144C

Complex Programmable Logic Devices Overview

The XC95144XL-7TQ144C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, designed for high-performance applications in 3.3V systems. It features 144 macrocells and approximately 3,200 usable gates, organized into eight Function Blocks. The device operates with a maximum propagation delay of 7 ns and supports internal system frequencies up to 178 MHz. It utilizes Flash memory technology for non-volatile configuration, allowing for in-system programming via JTAG. The component is housed in a 144-pin TQFP package, suitable for surface-mount assembly.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm commercial temperature range specifications. Confirm current availability status as older CPLD models may be subject to discontinuation notices. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells are required for moderate complexity logic designs. The -7 speed grade offers faster switching than -10 variants but may consume slightly more power. Verify that the TQFP144 package fits the PCB footprint constraints and thermal requirements of the target application environment.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, an evolution of the original XC9500 line offering higher density and improved performance. It serves as a drop-in replacement for many legacy CPLD designs while providing additional resources for modern embedded logic needs within the same pinout compatibility framework.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible alternatives within the XC9500XL family include the XC95144XL-10TQ144C for slower, lower-power applications. For higher performance needs, consider the XC95144XL-5TQ144C if available. Cross-family migration to XC9500 or XC9500X requires schematic review due to architectural differences.
