XCR3384XL-10TQ144I

Overview

The XCR3384XL-10TQ144I is a Complex Programmable Logic Device (CPLD) belonging to the XCR3000XL family, manufactured by AMD. It features 384 macrocells organized into four logic blocks and provides 108 I/O pins within a TQFP-144 package. The device utilizes EEPROM technology for non-volatile configuration and supports system-in-programmability via JTAG. Electrical specifications include a maximum operating frequency of 95 MHz and a typical propagation delay of 10 ns. It operates on a single 3.3V supply voltage with 5V-tolerant inputs.

Feature Summary

• Contains 384 macrocells across four function blocks for complex logic implementation
• Supports up to 108 user I/O pins with 5V tolerant input levels
• Features EEPROM-based non-volatile memory allowing infinite reprogramming cycles
• Includes IEEE 1149.1 JTAG boundary scan support for in-system programming

Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus arbitration in embedded architectures
• State machine implementation for automated manufacturing equipment
• Interface bridging between 3.3V and 5V logic domains

Procurement Notes

Verify the manufacturer source, as production has transitioned from Xilinx to AMD. Confirm the specific suffix 'I' indicates the industrial temperature range (-40°C to +85°C). Ensure the package designation matches the TQFP-144 form factor required for the target PCB layout. Check for RoHS compliance documentation corresponding to the specific manufacturing batch.

Selection Notes

Select this component when designs require more than 256 macrocells but less than the capacity of the XC9500XL series. The 10 ns speed grade is suitable for moderate-speed synchronous applications. Consider the 108 I/O count against pin availability requirements. Verify that the 3.3V core voltage aligns with the system power distribution network.

Part Context

This part is part of the XCR3000XL line, which succeeded the original XCR3000 series. It offers improved performance and lower power consumption compared to its predecessors while maintaining compatibility with existing design tools. The device serves as a bridge between low-density PLDs and high-density FPGAs, offering deterministic timing characteristics.
