1. Description  
The AT45DB161D is a 2.5-volt or 2.7-volt, serial-interface sequential access Flash  
memory ideally suited for a wide variety of digital voice-, image-, program code- and  
data-storage applications. The AT45DB161D supports RapidS serial interface for  
applications requiring very high speed operations. RapidS serial interface is SPI com-  
patible for frequencies up to 66 MHz. Its 17,301,504 bits of memory are organized as  
4,096 pages of 512 bytes or 528 bytes each. In addition to the main memory, the  
AT45DB161D 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  
3500J–DFLASH–4/08
