AT45DB081B-RU8D93 – ATMEL

The AT45DB081B-RU8D93 is an 8-Megabit (1024K x 8) serial interface Flash memory device utilizing a RapidS architecture. It operates from a 2.7V to 3.6V power supply and features a serial peripheral interface (SPI) compatible interface for read and write operations. The device incorporates two SRAM data buffers, each 512 bytes in size, allowing for continuous data streaming and efficient program/erase cycles. The RU suffix denotes a specific package type, likely a SOIC or similar surface-mount package, while the 8 indicates an operating temperature range, typically -40°C to +85°C. The D93 likely represents a specific speed grade or timing characteristic within the AT45DB081B family, requiring reference to the complete datasheet for precise specifications regarding clock frequency, access times, and other performance parameters. The 07+ designation indicates manufacturing compliance with RoHS standards after 2007.
