Atmel AT45DB081D Datasheet
The AT45DB081D is an 8‑Mbit serial‑interface Flash memory that operates from a single 2.5 V to 3.6 V supply and supports a RapidS® serial interface up to 66 MHz. It offers flexible page sizes (256 or 264 bytes), two SRAM buffers, continuous read capability, low‑power operation, and extensive data‑protection features.
The document provides pin‑out diagrams, a block diagram of the memory array, detailed descriptions of the memory architecture (sectors, blocks, pages), and the full instruction set for reading, programming and erasing the device. It also lists electrical characteristics, timing specifications, and recommended usage guidelines.
