XCR3256XL-12TQG144I

Overview

The XCR3256XL-12TQG144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XCR3000XL family, housed in a 144-pin Thin Quad Flat Package (TQFP). It features 256 macrocells and supports up to 120 I/Os. The device operates within a voltage range of 2.7 V to 3.6 V and includes EEPROM-based non-volatile configuration storage. Designed for industrial environments, it functions between -40°C and +85°C. Key electrical specifications include a maximum operating frequency of 154 MHz and a typical propagation delay of 7 ns, with a maximum supply current of 30 mA.

Feature Summary

• 256 Macrocells with 2 Logic Array Blocks (LABs)
• EEPROM non-volatile memory for instant-on configuration
• 154 MHz maximum operating frequency
• Industrial temperature range (-40°C to +85°C)

Applications

• High-density logic replacement
• Address/data bus muxing
• Board-level control logic

Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm lot codes and date codes against manufacturer records. Ensure proper ESD handling procedures are followed during inspection and storage. Check for moisture sensitivity level compliance prior to reflow soldering.

Selection Notes

Select this model when 256 macrocells and high pin counts are required in a TQFP package. Compare against the XCR3256XL-10 variant if a slower speed grade (10 ns vs 12 ns) suffices for the design timing requirements. Verify that the 3.3V core voltage aligns with the system power architecture.

Part Context

This part belongs to the XCR3000XL series, an enhancement of the original XCR3000 line. It offers improved performance and lower power consumption compared to legacy CPLDs while maintaining pin-to-pin compatibility with earlier generations in the same package footprint.

Replacement Considerations

The XCR3256XL-10TQG144I serves as a faster-speed-grade alternative within the same package and logic density. Cross-referencing with other manufacturers requires careful evaluation of pinout compatibility and voltage levels.
