AT45DB041D is a 2.5V or 2.7V serial-interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. It features flexible erase options, low power dissipation, and hardware and software data protection features.
The AT45DB041D is a 4‑megabit serial‑interface flash memory that operates from a single 2.5 V or 2.7 V supply up to 3.6 V. It offers a RapidS® serial interface with up to 66 MHz clock frequency, two SRAM buffers, and flexible erase options (page, block, sector, chip). The device is designed for low‑power, high‑density applications such as voice, image, code, and data storage.
The document details pin configurations, memory architecture (sectors, blocks, pages), and the full set of read, program, and erase commands. It includes timing diagrams, electrical characteristics, and programming procedures, enabling designers to integrate the AT45DB041D into commercial and industrial systems.
