XCR3384XL-10TQG144I

Overview

The XCR3384XL-10TQG144I is a Complex Programmable Logic Device (CPLD) from the CoolRunner XPLA3 series, manufactured by AMD. It features 384 macrocells and 118 I/O pins housed in a TQFP-144 package. The device operates on a supply voltage of 2.7 V to 3.6 V with a maximum operating frequency of 135 MHz and a typical propagation delay of 7 ns. It utilizes EEPROM storage technology for non-volatile configuration and supports system-in-system programming via JTAG.

Feature Summary

• Contains 384 macrocells and 9000 gates within 2 logic array blocks.
• Supports high-speed operation up to 135 MHz with 7 ns max propagation delay.
• Features EEPROM-based non-volatile memory for instant power-up configuration.
• Includes 118 I/O pins compatible with various logic standards.

Applications

• High-density logic replacement in industrial control systems.
• Address decoding and bus arbitration in embedded designs.
• State machine implementation requiring deterministic timing.
• Interface bridging between different voltage domains.

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or qualified second-source alternatives. Ensure that any sourced units are verified for authenticity and proper storage conditions due to the age of the product line.

Selection Notes

Select this part when a design requires moderate density (384 macrocells) with high pin count (118 I/O) in a TQFP package. It is suitable for applications needing fast, predictable logic delays and non-vatile configuration without external memory. Compare against the XCR3128XL for lower density needs or XC9500XL series for Flash-based alternatives if higher endurance is required.

Part Context

The XCR3384XL belongs to the CoolRunner XPLA3 family, which bridges the gap between traditional CPLDs and FPGAs. It offers the ease of use of a CPLD with performance levels approaching early FPGAs. The '10' suffix indicates the speed grade, while 'TQG144I' specifies the TQFP-144 package and industrial temperature range (-40°C to +85°C).

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific macrocell count and package. Consider the XCR3256XL for similar functionality with fewer I/Os. For modern equivalents, evaluate Lattice iCE40 or Xilinx Spartan-7 families, though these require architectural redesign.
