XCR3128XL-7TQ144I

Complex Programmable Logic Devices Overview

The XCR3128XL-7TQ144I is a Complex Programmable Logic Device (CPLD) belonging to the XCR3000XL family, manufactured by AMD. It features an EEPROM-based non-volatile configuration memory and contains 128 macrocells organized into two logic array blocks. The device supports up to 108 I/O pins and operates within a supply voltage range of 2.7 V to 3.6 V. It is housed in a TQFP-144 package with lead-free construction. The component is rated for industrial temperature ranges and supports system-in-system programming via JTAG.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells with 2 Logic Array Blocks (LABs)
• EEPROM non-volatile configuration memory
• Supports System-In-System Programming (SISP) via JTAG
• Industrial temperature range (-40°C to +85°C)

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement
• Interface bridging between different voltage domains
• Address decoding and control logic in embedded systems

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '7' indicates the -40°C to +85°C industrial temperature grade. Confirm the package type is TQFP-144. Check current availability status as older CPLD families may have limited stock or end-of-life implications from distributors.

Complex Programmable Logic Devices Selection Notes

Select this part when 128 macrocells are sufficient for the design. Ensure the design requires non-vatile storage to eliminate external configuration PROMs. Verify that the 3.3V (2.7V-3.6V) power domain matches the system requirements. Compare against XC3S series if higher performance or FPGA flexibility is needed.

Complex Programmable Logic Devices Part Context

This component is part of the Xilinx XCR3000XL family, which was acquired by AMD. These devices serve as low-power, high-density replacements for standard PALs and GALs. The XL variant offers improved speed and density compared to earlier XCR3000 versions while maintaining pin compatibility with legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include XCR3128XL-7TQ144C (commercial temp) or XCR3128XL-10TQ144I (slower speed). For upgrades, consider the XCR3256XL series for double the macrocells.
