It clocks at 85 MHz over the SPI bus, making it a solid choice for code shadowing, configuration storage, or data logging in embedded systems that need non-volatile storage with a small footprint. ## 85 MHz SPI — throughput for fast reads The 85 MHz SPI clock lets the host controller pull data at a practical read rate for firmware shadowing into RAM or streaming sensor logs. The page write time is 4 ms, and byte/word writes take 8 µs, so bulk writes are page-oriented — plan your write buffers around the 256-byte page size for best throughput. ## Supply range and temperature grade Rated for 1.7 V to 3.6 V supply, this part works in 1.8 V and 3.3 V systems without a level translator on the VCC rail — though the SPI signals still need matching levels. The -40°C to 85°C industrial temperature range covers outdoor telecom, factory automation, and automotive cabin applications. ## Package and rework notes Housed in an 8-SOIC narrow body (0.209\" wide, 5.30 mm body width), this is a surface-mount part with a standard pitch. No exposed pad to worry about, so rework is straightforward: preheat the board, hit the pins with flux, and lift the part without lifting the pad. ## Lifecycle and sourcing Listed as Active with ROHS3 compliance, so there is no last-time-buy pressure for new designs.","metaTitle":"AT45DB081E-SHN2B-T 8Mbit SPI Flash, 85 MHz, 8-SOIC","metaDescription":"AT45DB081E-SHN2B-T 8Mbit SPI Flash from Renesas (Dialog) — 85 MHz clock, 1.7V–3.6V supply, -40°C to 85°C.
