Description
The AT45D081A is a 5-volt only, serial 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 AT45D081A 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
