XCR3128XL-7TQ144C

Overview

The XCR3128XL-7TQ144C 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 TQFP-144 package. The device utilizes EEPROM technology for non-volatile configuration storage. Electrical specifications include a maximum operating frequency of 175 MHz and a typical propagation delay of 5.5 ns. It operates on a single 3.3 V supply voltage with a maximum current consumption of 30 mA. The component is designed for surface-mount installation and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• 128 Macrocells with 108 available I/O pins in a 144-pin TQFP package
• EEPROM-based non-volatile memory architecture for instant-on operation
• Maximum system clock frequency of 175 MHz with 5.5 ns propagation delay
• Single 3.3V power supply requirement with low current consumption

Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus bridging in embedded computing platforms
• State machine implementation for communication protocol interfaces
• Power-on reset generation and configuration management circuits

Procurement Notes

This component is identified as an End-of-Life (EOL) product. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the discontinuation status. Buyers should confirm the specific suffix variants and ensure compliance with RoHS directives before procurement.

Selection Notes

Select this part when a moderate density CPLD with EEPROM retention is required for 3.3V logic applications. The 175 MHz speed grade suits high-frequency digital logic tasks. Compare against the XCR3128XL-10 variant if slower switching speeds are acceptable for lower power consumption. Ensure the TQFP-144 footprint matches the PCB design constraints.

Part Context

The XCR3128XL-7TQ144C belongs to the XCR3000XL series, which succeeded the original XCR3000 line with improved performance and lower power consumption. This series was widely adopted for replacing discrete logic gates and smaller PLDs. AMD continues to support the architectural lineage through newer programmable logic families, though this specific model represents a mature, legacy solution.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to EOL status. Consider the XCR3128XL-10TQ144C for identical functionality with different timing characteristics. For modern equivalents, evaluate AMD's MachXO or Lattice's iCE40 series, noting that architectural differences may require schematic and firmware modifications.
