XC95144-10TQ100I

Complex Programmable Logic Devices Overview

The XC95144-10TQ100I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 144 macrocells, 3200 usable gates, and 8 Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3V (range 3.0V to 3.6V) with a maximum propagation delay of 10ns and a maximum operating frequency of 178MHz. It utilizes non-volatile Flash memory for configuration, eliminating the need for external programming devices. The component is housed in a TQFP-100 surface-mount package and supports an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• 144 Macrocells and 3200 Gates across 8 LABs
• Non-volatile Flash memory technology for instant-on operation
• High-speed performance: 10ns max propagation delay, 178MHz max frequency
• Industrial temperature range (-40°C to +85°C) and 3.3V supply

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus buffering in embedded designs
• State machine implementation for communication protocols
• Power-on reset generation and system initialization logic

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TQ100' against official datasheets, as standard nomenclature often uses 'TQFP100'. Confirm End-of-Life (EOL) status via manufacturer notifications, as this series has faced discontinuation notices. Ensure RoHS compliance documentation is available for current production batches or last-time buys.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells are required in a 100-pin TQFP package. Compare against the XC95144-10CSG144I if a BGA footprint is preferred for higher I/O density (117 vs 81 pins). Verify that the 10ns speed grade meets timing constraints; faster grades (e.g., -7) may be necessary for critical paths exceeding 178MHz effective throughput.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an enhanced version of the original XC9500 CPLDs. It offers improved power consumption and higher density while maintaining pin-to-pin compatibility with earlier generations. The series is characterized by its use of CMOS Flash technology, allowing for reprogrammability without volatile memory support.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the XC95144XL series (e.g., XC95144-7TQ100I). For package changes, the XC95144XL-10CSG144I offers the same logic density in a CSBGA-144 package but requires PCB layout redesign.
