Description
The AT45DB011 is a 2.7-volt only, serial interface Flash memory suitable for
in-system reprogramming. Its 1,081,344 bits of memory are organized as 512 pages
of 264 bytes each. In addition to the main memory, the AT45DB011 also contains one
SRAM data buffer of 264 bytes. Unlike conventional Flash memories that are
accessed randomly with multiple address lines and a parallel interface, the DataFlash
