The AT45DB021D 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
AT45DB021D supports RapidS serial interface for applications requiring very high
speed operations. RapidS serial interface is SPI compatible for frequencies up to 66
MHz. Its 2,162,688 bits of memory are organized as 1,024 pages of 256 bytes or 264
bytes each. In addition to the main memory, the AT45DB021D 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
uses a RapidS serial interface to sequentially
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.
