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. The part is sourced through independent distribution and quoted to order against an RFQ.
Package and mounting
Supplied in Tape & Reel (TR) or Cut Tape (CT) for surface-mount assembly. The exposed pad requires a thermal land pattern on the PCB; the centre pad must be soldered to a ground plane for heat dissipation. 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.
