Description

The AT45D011 is a 5.0-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 AT45D011 also contains one SRAM

data buffer of 264 bytes. Unlike conventional Flash memories that are accessed ran-

domly with multiple address lines and a parallel interface, the DataFlash uses a serial

interface to sequentially access its data. The simple serial interface facilitates hard-
