Product details

64 Mbit SPI NOR Flash in 8-SOIC — the BOM-fit tier

Operating temperature covers -40°C to 85°C, which puts it in the industrial-grade bracket — suitable for outdoor telecom enclosures, factory automation panels, and IoT edge nodes that see seasonal swings but not under-hood extremes. The write cycle timing is 8 µs for a word and 5 ms for a full page, which matters when estimating firmware update durations or logging sensor data at high cadence.

Sourcing posture — quoted to order against RFQ

This part is sourced and quoted to order through independent distribution. For a BOM line that needs a 64 Mbit SPI NOR Flash in an 8-SOIC, the AT45DB641E-SHN-B is a drop-in fit with no lifecycle risk.

Frequently asked questions

Is AT45DB641E-SHN-B obsolete?

No, the AT45DB641E-SHN-B is Active in production with no end-of-life notice. It is safe to specify for new designs.

Does AT45DB641E-SHN-B have a direct equivalent or cross reference?

The AT45DB641E-MHN-T and AT45DB641E-MHN-Y are functional equivalents with the same 64 Mbit density, 85 MHz SPI interface, and 8-SOIC package. The difference is packaging format: the -SHN-B ships in Tube, while the -MHN-T is Tape & Reel and the -MHN-Y is Tray. All share the same die and electrical specifications.
