Description  
AT45DB081  
The AT45DB081 is a 2.7-volt only, serial interface Flash memory suitable for in-sys-  
tem reprogramming. Its 8,650,752 bits of memory are organized as 4096 pages of  
264-bytes each. In addition to the main memory, the AT45DB081 also contains two  
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 memories 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 facil-  
itates hardware layout, increases system reliability, minimizes switching noise, and
