That 264-byte page size is the hallmark of the DataFlash architecture — it uses a dual-SRAM buffer scheme so writes are page-aligned, and a partial-page write triggers an internal read-modify-write cycle that takes 8 µs for the buffer load and 5 ms for the page erase. The SPI interface runs up to 85 MHz, which on a quad-I/O read gives a throughput ceiling around 34 MB/s — enough to shadow a firmware image into RAM or stream data-log buffers without stalling the host controller. ## Active lifecycle — no PCN watch needed Renesas lists the AT45DB641E-SHN-T as Active. ## Package and board-fit — 8-SOIC wide-body The supplier device package is 8-SOIC, and the mounting is surface-mount. ## Peer cross-reference — AT45DB641E-SHN2B-T drops in without rewiring The closest functional sibling is the AT45DB641E-SHN2B-T. The difference is in the ordering code suffix — the SHN2B variant uses a different test-flow revision.","metaTitle":"Renesas AT45DB641E-SHN-T 64Mbit SPI Flash, 85MHz, 8-SOIC","metaDescription":"Renesas AT45DB641E-SHN-T 64Mbit SPI flash, 85 MHz clock, 1.7-3.6V supply, -40 to +85°C.
