1. Description

The AT45DB011D is a 2.7V, serial-interface Flash memory ideally suited for a wide

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

AT45DB011D supports RapidS serial interface for applications requiring very high

speed operations. RapidS serial interface is SPI compatible for frequencies up to 66

MHz. Its 1,081,344 bits of memory are organized as 512 pages of 256 bytes or 264

bytes each. In addition to the main memory, the AT45DB011D also contains one

SRAM buffer of 256/264 bytes. EEPROM emulation (bit or byte alterability) is easily

handled with a self-contained three step read-modify-write operation. Unlike conven-

tional Flash memories that are accessed randomly with multiple address lines and a

parallel interface, the DataFlash

access its data. The simple sequential access dramatically reduces active pin count,

facilitates hardware layout, increases system reliability, minimizes switching noise,

and reduces package size.
