Description
The AT45DB041B is a 2.5-volt or 2.7-volt only, serial interface Flash memory ideally
suited for a wide variety of digital voice-, image-, program code- and data-storage
applications. 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
memor y is being reprogrammed, as well as reading or writing a continuous
data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-
