XCF128XFT64C

Overview

The XCF128XFT64C is a PROM device from the AMD/Xilinx Spartan-3A Pro FPGA family. It features 128 Mbit of non-volatile configuration memory and operates at a maximum frequency of 100 MHz. The component utilizes an SPI interface for programming and configuration, supporting standard voltage levels. It is housed in a 64-pin FineLine BGA package with a 0.8 mm pitch, designed for high-density board layouts. This device provides reliable storage for FPGA configuration data, ensuring system integrity upon power-up without requiring external volatile memory components.

Feature Summary

• Provides 128 Mbit of non-volatile configuration storage for Spartan-3A Pro FPGAs
• Supports serial peripheral interface (SPI) programming and configuration protocols
• Operates within standard industrial temperature ranges for robust performance
• Integrates into compact designs via a fine-pitch ball grid array package

Applications

• Configuration storage for Spartan-3A Pro field-programmable gate arrays
• Industrial control systems requiring reliable FPGA boot data retention
• Telecommunications infrastructure equipment needing secure configuration profiles
• Automotive electronics utilizing programmable logic controllers

Procurement Notes

Verify the specific suffix 'FTG64C' against official AMD documentation to confirm pinout compatibility and temperature grade. Ensure the source document explicitly lists this part number as available or supported. Confirm that the ordering information matches the exact package type and speed grade required for your design. Cross-reference the manufacturer's current product status to avoid obsolete components.

Selection Notes

Select this component when configuring Spartan-3A Pro devices requiring 128 Mbit capacity. Verify that the target application supports SPI mode operation. Ensure the PCB layout accommodates the 64-pin FineLine BGA footprint. Check thermal requirements against the specified operating range. Confirm compatibility with the host FPGA's configuration interface specifications.

Part Context

This part belongs to the XCF series of PROM devices developed by AMD (formerly Xilinx). These devices are specifically engineered to store configuration bitstreams for Spartan-3A and Spartan-3A Pro FPGAs. They serve as the primary non-volatile memory solution for these logic families, replacing older parallel configuration methods with more efficient serial interfaces.

Replacement Considerations

Consult AMD's official cross-reference guides for verified substitutes. Potential alternatives may include other XCF series parts with compatible capacities or interfaces. Verify package compatibility before substitution. Do not assume functional equivalence without checking electrical specifications.
