Product details

Active lifecycle and sourcing posture

Micron lists the MT25QU512ABB1EW9-0SIT TR as Active with ROHS3 compliance. No last-time-buy notice or obsolescence risk is on record.

Supplied in Tape & Reel (TR) or Cut Tape (CT) for surface-mount assembly. The 8-WPDFN (8x6 mm) footprint is shared across the MT25QU512 family.

Write timing and endurance

Page program time is 2.8 ms typical; a full 64 M x 8 array erase (sector or block) takes 8 ms. These timings matter for over-the-air firmware update scheduling — a multi-sector update can take several seconds at the page-program rate. The NOR architecture supports byte-addressable random access, so the part doubles as a data-log memory for small writes without erase-before-write penalties.

Frequently asked questions

Where can I buy the MT25QU512ABB1EW9-0SIT TR and get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing; no stock or price figures are published here.

What is the equivalent part for the MT25QU512ABB1EW9-0SIT TR?

The MT25QU512ABB8E12-0SIT TR is a functional equivalent — same 512 Mbit density, 133 MHz SPI Quad I/O, 1.8 V supply, and industrial temperature range. The difference is in the package: the 8E12 variant uses an 8-WDFN (8x6 mm) with a different supplier device code (MLP8-8). Verify footprint compatibility before substituting.
