It communicates over a standard SPI bus at up to 85 MHz, which in quad-I/O mode delivers roughly 34 MB/s read throughput — fast enough to copy a firmware image to RAM on power-up without stalling the processor. ## Page-write speed and buffer architecture A page write completes in 8 µs typical, and a page erase in 3 ms. The on-chip SRAM buffer lets you load the next page while the previous one is being written to the array — useful for data-logging or parameter-storage applications where the MCU cannot stall for milliseconds. The part is supplied on Tape & Reel for automated pick-and-place, with Cut Tape options available for prototype or low-volume builds.","metaTitle":"Renesas AT45DB041E-SHN2B-T 4Mbit SPI Flash, 85 MHz, 8-SOIC","metaDescription":"Renesas AT45DB041E-SHN2B-T 4Mbit SPI DataFlash, 85 MHz clock, 1.65-3.6V supply, industrial temp -40 to +85°C, 8-SOIC.
