XCF08PFSG48C

Overview

The AMD XCF08PFSG48C is a PROM-based FPGA configuration device belonging to the Spartan-3E system generator family. It utilizes Flash memory technology for non-volatile storage of configuration data, enabling rapid boot-up times for connected FPGAs. The component features an 8 Mbit (1M x 8) capacity and operates within a standard voltage range. It supports multiple configuration modes including Master Serial and Slave Serial, allowing flexible integration into various embedded designs. The device is housed in a 48-pin FineLine Plastic Small-Outline (FPAG) package, providing a compact solution for space-constrained applications requiring reliable FPGA initialization.

Feature Summary

• Utilizes non-volatile Flash memory technology for persistent configuration storage without power loss
• Supports multiple configuration interfaces including Master Serial and Slave Serial modes
• Enables fast boot-up times for connected Spartan-3E FPGAs upon power application
• Integrated on-chip oscillator for simplified clock generation during configuration

Applications

• Configuration storage for Spartan-3E field-programmable gate arrays
• Embedded systems requiring reliable FPGA initialization sequences
• Industrial control equipment with space-constrained PCB layouts
• Telecommunications infrastructure utilizing serial configuration protocols

Procurement Notes

Verify the specific suffix 'P' indicates plastic packaging and 'S' denotes small outline when sourcing replacements. Confirm the 'F' designation aligns with industrial or commercial temperature ranges required by your design environment. Ensure the manufacturer documentation matches the exact part number string to avoid confusion with similar capacity devices in the same series. Cross-reference the pinout diagram with your board schematic to confirm compatibility with existing traces.

Selection Notes

Select this component when a dedicated configuration PROM is required for Spartan-3E devices rather than using external SRAM or internal block RAM. Consider the 8 Mbit capacity limits against the bitstream size of your target FPGA design. Evaluate the need for serial configuration speeds versus parallel options if available in other family members. Assess the physical footprint requirements against the 48-pin FPAG package dimensions provided in the official datasheet.

Part Context

This device is part of AMD's broader portfolio of configuration solutions designed specifically for its Spartan and Virtex FPGA families. It serves as a critical interface component that bridges the gap between power-on reset and full FPGA operational state. The product line emphasizes reliability and ease of integration for mass-produced electronic systems where consistent startup behavior is mandatory.

Replacement Considerations

Direct substitutes include other parts from the Spartan-3E System Generator family with equivalent or higher density, such as the XCF04P or XCF16P variants, provided the pinout remains compatible. Verify that any replacement maintains the same package type and electrical specifications to ensure mechanical and functional interchangeability without redesigning the host circuit.
