Description  
The AT45DB321B is a 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 34,603,008 bits of memory are organized as 8192 pages of 528 bytes each. In  
addition to the main memory, the AT45DB321B also contains two SRAM  
data buffers of 528 bytes each. The buffers allow receiving of data while a page in the  
main memory is being reprogrammed, as well as reading or writing a continuous data
