Product details

8 Mbit SPI DataFlash — BOM-fit note

The AT45DB081E-MHN-T is a 8 Mbit serial DataFlash from Renesas, organized as 264 bytes per page across 4096 pages. SPI interface at 85 MHz clock — the quad-I/O read can saturate a 100 MHz bus without wait states.

Layout needs a solid ground pour under the package to keep RthJA under 60°C/W.

Write-cycle timing and page architecture

Page program time is 4 ms typical, byte write 8 µs — the page buffer lets you load up to 264 bytes before committing, which matches a 256-byte sector write without partial-page overhead. The 264-byte page (not 256) means the last 8 bytes can be used for metadata or ECC — a firmware engineer should account for the non-standard page size in the flash driver.

What is the closest functional alternative to AT45DB081E-MHN-T?

The AT45DB081E-UUN-T is the same 8 Mbit DataFlash with identical SPI interface, clock speed, and supply voltage — the difference is package (8-UDFN vs 8-UUN). The AT45DB081E-SHN-T and AT45DB081E-SSHN-T are SOIC-8 variants. All share the same memory organization and timing.
