Product details

8 Mbit SPI flash in a standard 8-SOIC footprint

The AT45DB081E-SSHN-B is an 8 Mbit serial flash from Renesas, organized as 264 bytes per page across 4096 pages.

Write timing and page-level granularity

Page program completes in 8 µs typical, while a page erase takes 4 ms. The erase time is the dominant factor for any write-heavy workload — if you are logging data every few seconds, budget the erase latency into the firmware loop or use a circular buffer across multiple pages. The 264-byte page size is slightly larger than a standard 256-byte sector, which means a firmware image built for a 256-byte page flash may need padding or alignment adjustments. Check the memory organization before porting code from a conventional serial flash.

The tube packaging suits manual assembly or low-volume kitting; for reel-fed pick-and-place, the tape-and-reel variant AT45DB081E-SSHN-T shares the same die and pinout.

Frequently asked questions

How is AT45DB081E-SSHN-B supplied and how do I order it?

The AT45DB081E-SSHN-B ships in tube packaging.

What is the closest functional second-source for AT45DB081E-SSHN-B?

The AT45DB081E-SSHN-T is the tape-and-reel variant of the same die — same 8 Mbit SPI flash, same 85 MHz clock, same 8-SOIC footprint. The only difference is packaging format, so it drops into the same PCB layout without any board change.
