1. Description
The Adesto
®
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
66MHz. 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 Adesto DataFlash
®
uses a RapidS serial interface to sequen-
tially 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.
