It is organized as 32 M x 8 or 16 M x 16, and operates from a 2.7 V to 3.6 V supply. The parallel interface provides direct random access for execute-in-place (XIP) code storage, with a 75 ns access time and a 60 ns write cycle time per word or page. Rated for the -40°C to 85°C industrial temperature range, it is suited for embedded systems requiring reliable non-volatile code storage in outdoor telecom, factory automation, and motor-drive environments. ## Active lifecycle — no LTB pressure The MT28EW256ABA1LJS-0SIT carries an active lifecycle status. Micron continues to manufacture this part; there is no last-time-buy notice or obsolescence date on record. ROHS3 compliance is confirmed. For BOM planning, this part can be specified without a near-term end-of-life watch. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.","metaTitle":"Micron MT28EW256ABA1LJS-0SIT 256Mbit NOR Flash, 75 ns","metaDescription":"Micron MT28EW256ABA1LJS-0SIT 256Mbit parallel NOR Flash in 56-TSOP. 75 ns access time, 2.7-3.6 V supply, -40 to 85°C.
