XCCACE-TQ144I

Overview

The AMD XCCACE-TQ144I is a CompactFlash memory controller IC designed for system-level FPGA configuration. It operates within a supply voltage range of 2.25V to 3.6V and supports an operating temperature range of -40°C to 85°C. The component is housed in a 144-LQFP surface-mount package with dimensions of 20x20 mm. It functions as part of the System ACE solution, providing non-volatile storage management for multiple FPGAs.

Feature Summary

• Integrates CompactFlash interface, JTAG boundary scan, and MPU bus interface for comprehensive configuration control.
• Supports automatic error correction and write retry mechanisms to ensure data integrity during programming.
• Enables multi-partition management and FAT12/16 file system compatibility for organized configuration storage.

Applications

• Configuration of multiple Field-Programmable Gate Arrays (FPGAs) in space-constrained systems.
• Non-volatile system solutions requiring high-density pre-designed configuration data.
• Embedded applications utilizing IBM PPC405 or Siemens 80C166 microprocessors via the MPU interface.

Procurement Notes

Verify component status carefully as this part is officially discontinued. Confirm that legacy designs can accommodate end-of-life constraints. Ensure replacement strategies align with long-term maintenance requirements. Check for available stock from authorized distributors before finalizing procurement plans. Validate that the 144-LQFP package remains compatible with existing PCB footprints.

Selection Notes

Select this controller when a compact, high-capacity solution for FPGA configuration is required. It is suitable for designs needing support for up to eight ACE flash cards or third-party CF cards. Consider its low-power CMOS characteristics and industrial temperature range for robust operation. Evaluate the need for JTAG chain throughput and MPU compatibility before adoption.

Part Context

This component belongs to the System ACE family developed by AMD (formerly Xilinx). It addresses the need for cost-effective, high-density configuration storage compared to traditional PROMs. The technology combines an ACE controller with ACE flash memory to streamline the configuration process for complex FPGA systems.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the discontinued status of this specific model. Designers should evaluate newer System ACE variants or alternative configuration controllers that offer similar interface capabilities and package compatibility.
