XCR3128XL-7CS144I

Overview

The XCR3128XL-7CS144I is a Complex Programmable Logic Device (CPLD) from the XCR3000XL family, manufactured by AMD. It features 128 macrocells and supports up to 108 I/O pins within a CSBGA-144 package. The device operates on an EEPROM storage type and functions within a voltage range of 2.7 V to 3.6 V. Key electrical specifications include a maximum operating frequency of 175 MHz and a typical propagation delay of 5.5 ns. Designed for surface-mount installation, it supports system-in-system programming and JTAG boundary scan testing.

Feature Summary

• 128 Macrocells with 3000 usable gates across 2 Logic Array Blocks
• High-speed performance with 175 MHz max frequency and 5.5 ns propagation delay
• EEPROM non-volatile memory technology for instant-on functionality
• Supports System-In-System Programming (SISP) and JTAG boundary scan

Applications

• Complex logic replacement in industrial control systems
• Address/data bus buffering and protocol conversion
• Clock generation and distribution circuits
• State machine implementation in embedded designs

Procurement Notes

This component is listed as End-of-Life (EOL). Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Supply chain stability cannot be guaranteed through standard manufacturing channels. Buyers should confirm the specific revision level and packaging condition before acquisition.

Selection Notes

Select this part when designing with 2.7V to 3.6V supplies requiring 128 macrocells. The CSBGA-144 package suits high-density surface-mount applications. Ensure design tools support the XCR3000XL architecture. Consider thermal management for the BGA package if multiple devices are active simultaneously.

Part Context

Part of the XCR3000XL CPLD family, which bridges the gap between simple PLDs and FPGAs. The XCR3128XL variant specifically offers 128 macrocells. AMD acquired Xilinx's programmable logic assets, leading to dual branding in documentation. This series emphasizes low power consumption and ease of use compared to FPGA alternatives.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to the EOL status. Evaluate newer Xilinx/AMD CPLD families such as the XC9500XL or Spartan-7 series for functional equivalents. Verify that alternative packages accommodate the required I/O count and voltage levels.
