Description

The AT45DB080 is a 2.7-volt only, sequential access, parallel interface Flash memory

suitable for in-system reprogramming. Its 8,650,752 bits of memory are organized as

4096 pages of 264-bytes each. In addition to the main memory, the AT45DB080 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 memo-

ries that are accessed randomly with multiple address lines and a parallel interface,
