Description  
AT45DB041  
The AT45DB041 is a 2.7-volt only, serial interface Flash memory suitable for in-sys-  
tem reprogramming. Its 4,325,376 bits of memory are organized as 2048 pages of  
264-bytes each. In addition to the main memory, the AT45DB041 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. Unlike conventional Flash memo-  
ries that are accessed randomly with multiple address lines and a parallel interface,  
the DataFlash uses a serial interface to sequentially access its data. The simple serial  
interface facilitates hardware layout, increases system reliability, minimizes switching
