1. Description  
The AT45DB321D is a 2.7-volt, serial-interface sequential access Flash memory  
ideally suited for a wide variety of digital voice-, image-, program code- and data-stor-  
age applications. The AT45DB321D supports RapidS serial interface for applications  
requiring very high speed operations. RapidS serial interface is SPI compatible for  
frequencies up to 66 MHz. Its 34,603,008 bits of memory are organized as 8,192  
pages of 512 bytes or 528 bytes each. In addition to the main memory, the  
AT45DB321D also contains two SRAM buffers of 512/528 bytes each. The buffers  
allow the receiving of data while a page in the main Memory is being reprogrammed,  
as well as writing a continuous data stream. EEPROM emulation (bit or byte alterabil-  
ity) is easily handled with a self-contained three step read-modify-write operation.  
Unlike conventional Flash memories that are accessed randomly with multiple  
address lines and a parallel interface, the DataFlash uses a RapidS serial interface to
