Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing this component. Confirm that the manufacturer part number matches the exact electrical specifications required for your design, particularly the voltage range and interface modes. Ensure compatibility with existing PCB footprints for the SOIC-16 package if applicable. Cross-reference with official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Memory IC Selection Notes

Select this component for designs requiring high-density non-volatile storage with flexible access speeds. Consider the 104MHz clock support for applications needing fast read performance. Evaluate the need for Quad SPI versus standard SPI based on pin availability and performance requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental constraints. Check for necessary security features like write protection if data integrity is critical.

Memory IC Part Context

The W25Q256FV belongs to Winbond's SpiFlash series, offering enhanced flexibility and performance over ordinary serial flash devices. This series is designed for systems with limited space, pins, and power. The FV variant specifically denotes the 3V operation and SOIC/WSON package options within the broader W25Q256 family, which includes various package codes and interface configurations.

Memory IC Replacement Considerations

Direct substitutes include other W25Q256 variants with compatible pinouts and electrical characteristics. Verify package type compatibility, such as SOIC-16 or WSON-8, when selecting alternatives. Ensure that any replacement part supports the same SPI modes and voltage ranges. Consult manufacturer documentation for cross-reference lists to identify equivalent components with similar capacity and feature sets.
