It is a non-volatile memory for firmware storage, parameter logging, or code shadowing in embedded systems where a small footprint and low pin count matter. The 8-SOIC package and surface-mount assembly suit compact PCBs in industrial controls, IoT edge nodes, and telecom modules. The supply range is 1.7 V to 3.6 V. ## 85 MHz SPI clock and page write timing The 85 MHz clock rate delivers read throughput suitable for direct code execution (XIP) or fast firmware downloads. Page write completes in 8 µs, and a full sector erase takes 4 ms — fast enough for over-the-air updates or frequent data logging without stalling the application. The 256-byte page size aligns well with common Flash file systems and bootloader block sizes. ## Industrial temperature grade Rated for -40°C to 85°C, the part is qualified for outdoor telecom cabinets, factory-floor automation, and engine-bay-adjacent electronics where the ambient temperature swings wide. The 85°C upper limit covers most industrial enclosures without active cooling. ## Lifecycle and sourcing posture The AT45DB081E-SSHN2B-T is listed as Active with ROHS3 compliance.","metaTitle":"AT45DB081E-SSHN2B-T 8Mbit SPI NOR Flash, 85 MHz, 8-SOIC","metaDescription":"AT45DB081E-SSHN2B-T 8Mbit SPI NOR Flash, 85 MHz clock, 1.7V-3.6V supply, -40°C to 85°C.
