Where the MT25Q family fits.

MT25Q is a strong fit when a design needs dependable boot or code storage, fast reads, and a broad range of configurations. The family name is only the beginning; confirm the complete manufacturer part number before you order.

Start with the system voltage and boot architecture, then verify package, temperature grade, and qualification level. A family name alone isn't enough to make a safe cross-reference.

Talk to the people who work this line.

For design-in, samples, lifecycle questions, availability planning, or a difficult cross-reference, start with our Micron technical team.

Micron gave our field application engineer Keith Peterson its 2025 Americas Distribution FAE Recognition Award for Excellent Technical Support.
Ask us about product-selection help, manufacturer technical resources, and supply or lifecycle support for your program.

Frequently asked questions

How do I choose between the 1.8 V and 3.0 V families?

Choose the voltage required by the board’s power supply and host interface. In the ordering matrix, MT25QU parts are the 1.7–2.0 V family and MT25QL parts run 2.7–3.6 V. If both rails are available in your system, talk the trade-offs through with us before qualification begins.

What densities does the family cover?

MT25Q spans 128 Mb to 2 Gb, with the points in between in the parts list below. We'll confirm what's current across the full range.

Are automotive temperature grades available?

The family carries industrial and automotive temperature options. The automotive path adds qualification requirements, so confirm the grade and the exact part number with us before the design commits to it.

Why isn't the family name enough to order a part?

Voltage, density, package, temperature grade, and qualification level all live in the complete manufacturer part number. Two parts sharing a family name may not be interchangeable. Verify the exact part number, or contact us for help matching the electrical and package requirements.

What if MT25Q isn't the right architecture?

When quad SPI throughput becomes the bottleneck, Micron's octal-interface Xccela line, the MT35X series, is the migration path. When density economics matter more than execute-in-place, serial NAND is the alternative, a different architecture and not a drop-in swap. Tell us the constraint and we'll narrow it with you.
