Description
The 45DB041B is a serial interface Flash memory designed for various digital voice-, image-, program code-, and data-storage applications. It operates at a voltage range of 2.5V to 2.7V and has a storage capacity of 4,325,376 bits, which is organized into 2048 pages of 264 bytes each. In addition to the main memory, it also features two SRAM data buffers, each with a capacity of 264 bytes. These buffers allow data receiving while a main memory page is being reprogrammed and enable continuous data stream read or write operations.
