Memory IC Procurement Notes

This component is officially marked as obsolete or discontinued by Micron Technology. Availability is limited to existing stock or secondary market sources. Verify the exact lifecycle status directly with the manufacturer or authorized distributors before design finalization. Sourcing may involve significant lead times or premium pricing due to end-of-life status. Ensure compatibility with replacement parts if this component is no longer producible.

Memory IC Selection Notes

Select this part only if legacy compatibility is required, as it is discontinued. Consider newer Micron NOR flash series with similar pinouts and capacities for new designs. Verify that the 75 MHz SPI speed and 3.6 V maximum voltage meet system requirements. Check for alternative packages if SOIC-8 is unavailable in the market. Evaluate supply chain stability given the obsolete status.

Memory IC Part Context

The M25P40 series represents Micron's standard SPI NOR flash lineup designed for general-purpose storage. The VMN6 suffix typically denotes specific package and temperature grade variations within the M25P40 family. These components are widely used in embedded applications where small code sizes and high reliability are prioritized over large data storage capacities.

Memory IC Replacement Considerations

Consult Micron's official cross-reference tools for direct replacements. Potential substitutes include other M25P40 variants with updated packaging or newer density levels like M25P80 if capacity allows. Verify pin compatibility and electrical specifications before substitution.
