ATMEL AT45DB041B handbook
The AT45DB041B is an SPI compatible serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applica- tions. Its 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each. In addition to the main memory, the AT45DB041B also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being repro- grammed, as well as reading or writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step Read-Modify- Write operation. Unlike conventional Flash memories that are accessed randomly with multiple pages, the AT45DB041B supports page programming, allowing programming or erasing a single page in a single clock cycle.
