Product details

Industrial temperature range and active lifecycle

Rated for -40°C to 85°C, this part fits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics. 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.

Frequently asked questions

What is the difference between AT45DB321E-MHF-Y and AT45DB321E-MHF-T?

The die and electrical specs are identical — both are 32 Mbit SPI Flash in an 8-UDFN package. The -Y suffix ships in Tray; the -T suffix ships in Tape & Reel. Choose -T for automated pick-and-place assembly, -Y for bench prototypes or low-volume builds.

Is AT45DB321E-MHF-Y RoHS compliant?

Yes, it is ROHS3 compliant, covering all six original RoHS substances plus the four phthalates added in EU 2015/863.

Can AT45DB321E-MHF-Y be used as a replacement for AT45DB321E?

The AT45DB321E-MHF-Y is a specific variant of the AT45DB321E family. 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.

What are the specifications of AT45DB321E-MHF-Y?

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.
