Description

The AT45DB161D is a 2.5V or 2.7V, serial-interface sequential access Flash memory
ideally suited for a wide variety of digital voice-, image-, program code- and data-stor-
age applications. The AT45DB161D supports RapidS serial interface for applications
requiring very high speed operations. RapidS serial interface is SPI compatible for
frequencies up to 66MHz. Its 17,301,504-bits of memory are organized as 4,096
pages of 512-bytes or 528-bytes each. In addition to the main memory, the
AT45DB161D also contains two SRAM buffers of 512-/528-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 alterabil-
ity) is easily handled with a self-contained three step read-modify-write
