It communicates over a standard SPI bus at up to 85 MHz, making it a drop-in code or data storage companion for any MCU with an SPI peripheral — common in IoT edge nodes, industrial sensors, and embedded control boards that need non-volatile storage for firmware images, configuration tables, or data logs. ## Package and mounting 8-pin SOIC narrow body (3.90 mm width), surface-mount. Standard reflow profile; no underfill needed. Footprint matches legacy 8-SOIC Flash parts. ## Lifecycle and sourcing The part is ROHS3 compliant.","metaTitle":"AT45DB041E-SSHN2B-T 4Mbit SPI Flash, 85 MHz, 8-SOIC","metaDescription":"AT45DB041E-SSHN2B-T 4Mbit SPI Flash, 85 MHz clock, 1.65-3.6V supply, -40 to 85°C, 8-SOIC.

The supply range is 1.65 V to 3.6 V, so a 3.3 V rail is well within spec. The SPI I/O levels track VCC, so no level translation is needed when connecting to a 3.3 V MCU."},{"question":"What is the replacement or equivalent for AT45DB041E-SSHN2B-T?","answer":"The closest functional equivalent is the AT45DB041E-SSHN-T, which shares the same 4 Mbit density, 85 MHz SPI speed, 8-SOIC package, and -40°C to 85°C temperature range. The difference is the memory organisation: 264 bytes per page on the -SSHN-T versus 256 bytes per page on the -SSHN2B-T. Verify page size compatibility with your firmware before substituting."},{"question":"How do I interface AT45DB041E-SSHN2B-T with an Arduino?","answer":"Connect the SPI pins (MOSI, MISO, SCK, CS) to the Arduino's hardware SPI header. Use the standard SPI library; set the clock divider for 8 MHz or lower (the part runs at 85 MHz, but Arduino SPI tops out around 8-16 MHz). The 256-byte page size maps naturally to the library's page read/write functions. No level shifter needed if the Arduino runs at 3.3 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/AT45DB041E-SSHN2B-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/AT45DB041E-SSHN2B-T when reusing this data.
