Description  
The AT45DB011B 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 1,081,344 bits of memory are organized as 512 pages of 264 bytes each. In addi-  
tion to the main memory, the AT45DB011B also contains one SRAM data buffer of 264  
bytes. The buffer allows receiving of data while a page in the main memory is being  
reprogrammed. EEPROM emulation (bit or byte alterability) 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 inter-  
face, the DataFlash uses a SPI serial interface to sequentially access its data. SPI  
mode 0 and mode 3 are supported. The simple serial interface facilitates hardware
