1. Description

The AT45DB041D is a 2.5V or 2.7V, serial-interface Flash memory ideally suited for a

wide variety of digital voice-, image-, program code- and data-storage applications.

The AT45DB041D supports RapidS serial interface for applications requiring very

high speed operations. RapidS serial interface is SPI compatible for frequencies up to

66 MHz. Its 4,325,376 bits of memory are organized as 2,048 pages of 256 bytes or

264 bytes each. In addition to the main memory, the AT45DB041D also contains two

SRAM buffers of 256/264 bytes each. The buffers allow the receiving of data while a

page in the main Memory is being reprogrammed, as well as writing a continuous data

stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-con-

tained three step read-modify-write operation. Unlike conventional Flash memories

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

DataFlash uses a RapidS serial interface to sequentially access its data. The simple

sequential access dramatically reduces active pin count, facilitates hardware layout,
