Description
The AT45DB081B 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 8,650,752 bits of memory are organized as 4096 pages of 264 bytes
each. In addition to the main memory, the AT45DB081B 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 reprogrammed, as well as writing a continuous data stream.
