XCR3128XL-10VQ100C

Overview

The XCR3128XL-10VQ100C is a Complex Programmable Logic Device (CPLD) from the XCR3000XL family, manufactured by AMD (formerly Xilinx). It features 128 macrocells and supports up to 84 I/O pins in a 100-pin VQFP package. The device operates within a voltage range of 2.7 V to 3.6 V and functions at temperatures between -40°C and +85°C. Key electrical specifications include a maximum operating frequency of 175 MHz and a maximum propagation delay of 5.5 ns.

Feature Summary

• 128 Macrocells with 84 available I/Os
• High-speed performance: 175 MHz max frequency, 5.5 ns max propagation delay
• Industrial temperature range: -40°C to +85°C
• Single power supply operation: 2.7 V to 3.6 V

Applications

• General-purpose logic replacement
• Address/data bus buffering
• Clock drivers and synchronizers
• Finite state machine implementation

Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Production has ceased, and no new units are available directly from AMD. Sourcing is limited to existing stock or secondary market distributors. Verification of authenticity and condition is critical when purchasing from third-party suppliers due to the discontinued status.

Selection Notes

Select this part for designs requiring low pin counts and moderate speed in a compact VQFP-100 package. Ensure the design voltage aligns with the 2.7–3.6 V range. For higher density or modern features, consider upgrading to newer CPLD families such as the XC9500XL series or FPGA alternatives, as the XCR3128XL is obsolete.

Part Context

The XCR3128XL belongs to the XCR3000XL family of CPLDs, which utilize CMOS Flash technology for non-volatile configuration. This family was designed for cost-sensitive applications requiring simple programmable logic. The '10' suffix indicates the 10 ns speed grade, and 'VQ100' denotes the 100-pin Very Thin Quad Flat Package variant.

Replacement Considerations

As an EOL component, direct functional replacements may require redesign. Potential substitutes include other Xilinx CPLDs like the XC95144 or XC95288 if pin compatibility allows, or modern FPGAs from AMD/Xilinx or Lattice Semiconductor. Verify pinout and I/O voltage compatibility before substituting.
