XC95144XL-10TQG144I

Complex Programmable Logic Devices Overview

The XC95144XL-10TQG144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 144-pin TQFP package. It features 144 macrocells and approximately 3,200 usable gates organized into eight Function Blocks. Operating at a supply voltage of 3.0 V to 3.6 V (typical 3.3 V), it delivers a maximum propagation delay of 10 ns and supports internal system frequencies up to 178 MHz. The device utilizes non-volatile Flash memory for configuration, enabling In-System Programming (ISP) via JTAG.

Complex Programmable Logic Devices Feature Summary

• 144 Macrocells with enhanced product-term allocation across 8 Function Blocks
• 10 ns maximum propagation delay with 178 MHz internal clock capability
• Non-volatile Flash technology supporting >10,000 erase/rewrite cycles
• 5V tolerant I/Os with bus-hold and input hysteresis for noise immunity

Complex Programmable Logic Devices Applications

• High-density glue logic replacement in embedded systems
• State machine implementation for industrial control
• Bus bridging and protocol conversion interfaces
• I/O buffering and level translation between voltage domains

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as the XC9500XL series has been discontinued by AMD. Check manufacturing date codes against discontinuation notices issued around January 2024. Ensure suppliers provide traceability documentation, as availability may be limited to surplus or recycled stock rather than new production units.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells are required in a TQFP-144 footprint. The -10 speed grade is suitable for designs requiring 10 ns timing constraints. Verify that the design does not exceed the 45 mA typical operating current. Consider the -7 variant if lower power consumption is prioritized over the fastest switching speeds.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL high-performance CPLD line, which succeeded the original XC9500 series. It offers higher density and faster performance while maintaining compatibility with existing XC9500 design tools. The series was widely used for cost-effective programmable logic solutions before being phased out in favor of newer FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

No direct pin-to-pin replacements are available due to the discontinuation of the XC9500XL family. Designers must migrate to modern FPGA platforms such as the Lattice iCE40 or Xilinx Artix-7 series, requiring schematic and firmware redesign.
