XC95144XL-10TQ144I

Complex Programmable Logic Devices Overview

The XC95144XL-10TQ144I 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 3.0V to 3.6V and supports up to 117 user I/Os in its TQFP-144 package. Key electrical specifications include a maximum propagation delay of 10 ns and a maximum operating frequency of 178 MHz. It utilizes Flash memory technology for non-volatile configuration and supports In-System Programming via IEEE-1149.1 JTAG.

Complex Programmable Logic Devices Feature Summary

• High-density logic architecture with 144 macrocells and FastCONNECTII routing structure.
• Supports In-System Programming (ISP) and boundary scan testing via standard 4-pin JTAG interface.
• Flash-based non-volatile storage ensures data retention without battery backup.
• Enhanced product-term allocation allows flexible logic implementation with up to 90 terms per macrocell.

Complex Programmable Logic Devices Applications

• System control and glue-logic replacement in embedded designs.
• I/O buffering and level translation between different voltage domains.
• State machine implementation and bus bridging applications.
• Interface protocol front-ends requiring reprogrammable logic.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'I' indicates industrial temperature range operation (-40°C to +85°C). Check for recent discontinuation notices as older CPLD families may face end-of-life status. Ensure ESD protection measures are followed during handling due to moisture sensitivity classification.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells are required for complex combinational or sequential logic. The -10 speed grade is suitable for designs needing sub-10ns output delays. Consider the TQFP-144 package only if surface-mount leaded pins are preferred over BGA options. Verify that the 3.3V core voltage and 5V-tolerant inputs match the target system's power and I/O standards.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an evolution of the original XC9500 line offering higher density and improved performance. It serves as a drop-in compatible upgrade for legacy XC9500 designs while providing additional macrocells and faster switching speeds. The series is widely used in industrial and consumer electronics for cost-effective programmable logic solutions.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified against current AMD/Xilinx availability lists. Alternative packages such as CSG144 (CSBGA) offer the same logical resources but require PCB layout adjustments. Cross-series upgrades may require design resynthesis due to differences in function block architecture.
