The AT45DB011D is a 2.7V, serial-interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB011D supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 256 byte page size and flexible erase options make it ideal for large-capacity data storage applications. It also features low power consumption and high data retention.
The AT45DB011D is a 1‑megabit serial‑interface Flash memory designed for low‑pin‑count, low‑voltage, and low‑power applications. It features a RapidS® serial interface capable of up to 66 MHz clock rates, selectable page sizes of 256 bytes or 264 bytes, and a single 256‑byte SRAM buffer. The device supports a variety of erase options (page, block, sector, chip) and includes hardware data‑protection features such as sector lockdown and a 128‑byte security register.
The manual describes the pinout, memory architecture, and the full set of read, program, and erase commands. It details timing requirements, voltage ranges (2.7 V–3.6 V), and power consumption figures, making it a comprehensive reference for designers integrating the AT45DB011D into voice, image, code, or data‑storage applications.
