XCF04SVOG20C

Overview

The XCF04SVOG20C is a 4 Mbit Platform Flash PROM designed for in-system programmable configuration of Xilinx FPGAs. It utilizes a 3.3V supply voltage and supports Master Serial and Slave Serial FPGA configuration modes. The device features a TSSOP-20 package with industrial temperature range operation from -40°C to +85°C. It offers up to 20,000 program/erase cycles and includes IEEE standard 1149.1/1532 boundary scan support.

Feature Summary

• In-system programmable NOR flash memory architecture for storing FPGA configuration bitstreams
• Supports Master Serial and Slave Serial configuration interfaces for Xilinx FPGAs
• Integrated JTAG boundary scan capability for programming and testing via IEEE standards
• Low-power CMOS process technology with high endurance for repeated reconfiguration

Applications

• Configuration storage for small to medium density Xilinx FPGAs
• Industrial control systems requiring reliable FPGA boot-up data
• Embedded designs needing in-field reprogrammable logic configuration
• Prototyping environments utilizing JTAG-based configuration workflows

Procurement Notes

Verify component authenticity carefully as this part is discontinued. Supply chains may contain refurbished or counterfeit units. Confirm package marking and datasheet revisions match the specific lot code. Ensure compatibility with existing board layouts for the TSSOP-20 footprint before procurement.

Selection Notes

Select this component only for legacy designs requiring exact 4 Mbit capacity and 3.3V operation. Evaluate pinout compatibility if migrating to newer XCF series devices. Consider that newer alternatives may offer higher densities or different voltage levels, requiring schematic adjustments. Verify software toolchain support for the specific configuration mode required by the target FPGA.

Part Context

This device belongs to the Xilinx Platform Flash PROM family, specifically the XCFxxS series designed for 3.3V applications. It serves as non-volatile memory to initialize FPGA logic upon power-up. The VOG20 suffix indicates the specific TSSOP-20 package variant used for space-constrained PCB designs.

Replacement Considerations

Public confirmed substitutes include other XCFxxS series devices such as XCF02S or XCF08S, provided pinouts and capacities align with design requirements. Cross-brand SPI Flash replacements require significant interface adaptation and are not direct pin-compatible substitutes.
