XCR3384XL-12TQ144I

Overview

The XCR3384XL-12TQ144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XCR3000XL family. It features 84 macrocells and supports up to 64 I/O pins within a TQFP-144 package. The device operates on a single 3V to 3.6V supply voltage and utilizes non-volatile EEPROM technology for configuration retention. Designed for industrial applications, it ensures reliable performance across an extended temperature range of -40°C to +85°C with a maximum operating frequency of 125 MHz.

Feature Summary

• 84 Macrocells with 64 I/Os in a TQFP-144 package
• Non-volatile EEPROM memory for instant-on operation
• Industrial temperature range (-40°C to +85°C)
• Single 3.3V power supply operation

Applications

• Industrial control systems requiring deterministic logic
• Automotive electronics interfaces
• Communication protocol conversion
• Memory interface adapters

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type is TQFP-144. Check current availability status as legacy CPLDs may have limited stock or end-of-life implications. Ensure design-in documentation matches the XCR3000XL datasheet specifications.

Selection Notes

Select this component when non-volatile configuration is required without external boot ROMs. Compare against the commercial grade variant (suffix 'C') if the application environment remains within 0°C to +70°C. Verify that 84 macrocells provide sufficient logic density for the target design complexity before finalizing the part number.

Part Context

This part belongs to the XCR3000XL series, which succeeded the original XCR3000 line. The XL variants offer improved performance and lower power consumption while maintaining pin-to-pin compatibility with previous generations. The XCR3384XL specifically targets designs needing moderate logic capacity with robust I/O capabilities.

Replacement Considerations

Direct pin-compatible replacements include other XCR3000XL devices with equal or higher macrocell counts, such as the XCR3512XL. Verify that any substitute maintains the same EEPROM architecture and voltage requirements to ensure functional equivalence in existing PCB layouts.
