The Micron MT25QL256ABA1EW7-0SIT is a 256 Mbit serial NOR Flash memory built for code shadowing, firmware storage, and data logging in embedded systems. The 8-WPDFN (6x5 mm) package with exposed pad suits space-constrained designs on standard FR4, and the -40°C to 85°C temperature range covers industrial and outdoor telecom environments.
There is no end-of-life notice or last-time-buy date on record.
The MT25QL256ABA8ESF-0SIT is a functional equivalent — same 256 Mbit density, 133 MHz Quad I/O, and industrial temperature range — but packaged in an 8-SOIC. For the same 8-WPDFN package, the MT25QL256ABA8E12-1SIT is a direct drop-in alternate. Verify the exact package code against your board footprint before substituting.
