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.","metaTitle":"Renesas AT45DB081E-SSHN-B 8Mbit SPI Flash, 85 MHz, 8-SOIC","metaDescription":"Renesas AT45DB081E-SSHN-B 8Mbit SPI flash in 8-SOIC tube. 85 MHz clock, 1.7-3.6 V supply, -40 to +85°C.
