Description
The AT45D041 is a 5-volt only, serial interface Flash memory suitable for in-system
reprogramming. Its 4,325,376 bits of memory are organized as 2048 pages of 264-
bytes each. In addition to the main memory, the AT45D041 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
