ROHS3 compliance covers EU and other regulated markets without exemption paperwork. ## Write timing for in-system updates Page write takes 8 µs; a full page program (528 bytes) completes in 4 ms. For data-logging applications, the 8 µs page write lets you capture sensor bursts without dropping samples, as long as the host buffers a full page before writing. ## Tray packaging — order the Tape & Reel variant for volume This specific suffix (-Y) ships in Tray, which is typical for engineering samples, prototype runs, or low-volume production. If your pick-and-place line needs Tape & Reel, the sibling AT45DB321E-MHF-T is the same die in the same 8-UDFN package but on reel. Both are electrically identical — the only difference is the shipping medium.","metaTitle":"AT45DB321E-MHF-Y 32Mbit SPI Flash, 85MHz, 8-UDFN","metaDescription":"AT45DB321E-MHF-Y 32Mbit SPI Flash, 85MHz clock, 2.3-3.6V, -40 to 85°C, 8-UDFN exposed pad.

If your BOM calls for the base AT45DB321E in an 8-UDFN package, this -Y suffix (Tray) is electrically compatible. Verify the package code and temperature grade match your existing design — the -MHF suffix indicates the 8-UDFN package and industrial temperature range."},{"question":"What are the specifications of AT45DB321E-MHF-Y?","answer":"32 Mbit SPI DataFlash, 85 MHz clock, 2.3 V to 3.6 V supply, -40°C to 85°C operating temperature, 8-UDFN exposed pad package (5x6 mm), organized as 528 bytes x 8192 pages, with 8 µs page write and 4 ms page program times."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/AT45DB321E-MHF-Y","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/AT45DB321E-MHF-Y when reusing this data.
