The Adesto Technologies AT45DB041E-SSHN-T is a 4 Mb (512 KB) Data Flash serial flash memory with an SPI interface, supplied in an 8-pin SOIC package on tape and reel. It is organized as 512000 words of 8 bits with a 19-bit address bus and an 8-bit data bus, and is rated for operation at up to 85 MHz with a 7 ns access time. The device operates from a wide 1.65 V to 3.6 V supply (1.8 V nominal) at 15 mA supply current. AT45DB041E-SSHN-T is a RoHS-compliant, lead-free surface-mount device rated -40 C to +85 C.

Serial flash provides non-volatile code and data storage over a few-pin SPI bus, and Data Flash devices are distinguished by small page sizes and on-chip SRAM buffers, which lets a host rewrite a small record without erasing a large sector. That behavior suits frequently updated data in systems with limited RAM. Typical uses for the AT45DB041E-SSHN-T are firmware and bootloader storage, over-the-air update staging, configuration and calibration records, event logs, and font or display asset storage. The 1.65 V minimum supply and wide temperature range fit battery-powered and industrial designs including wireless modules, IoT endpoints, wearables, metering, medical devices and instrumentation. Buyers are typically embedded designers and ODMs needing modest, frequently written non-volatile storage.
